Voice Extreme™ Toolkit
Quick Start Manual
Software & Hardware Installation
1. Insert the Voice Extreme Toolkit CD into your CD-ROM reader. The CD menu program will run
automatically. If not, please run the setup.exe file located in the root directory of the CD.
2. Using the supplied serial cable, connect the Development Board to a spare RS-232 port on your PC.
Some PCs have 25-pin RS-232 connectors, in which case you will need a 9-pin to 25-pin adapter. If the
serial port is being shared with another application or device, make sure that the other application does not
have that COM port open. For Voice Extreme, you must choose either COM 1 or COM 2 as a serial port.
3. Connect the power supply to the Development Board using the power jack (adjacent to the serial port pictures and descriptions are included in the hardware section of this manual). If power is connected
properly, the green LED near the power jack will be lit. It is good practice to press the RESET button after
making all connections.
4. The Voice Extreme IDE software can be launched via the icon on your desktop or by using the Windows
Start -> Programs -> Sensory -> Voice Extreme -> Voice Extreme IDE menu item. By default, the program
expects the Development Board to be connected to COM 1. If you are using COM 2, make the appropriate
selection in the Options panel (go to Tools -> Options menu).
5. Start developing! This kit has been designed to streamline the process of enabling your product to talk
and hear. The general process consists of 3 steps:
Write, edit, and build your program using the Voice Extreme™ IDE Software
Download the program over RS-232 to the VE module
Run the program directly on the module!
Let’s Go!

Quick Start Manual
What is a Voice Extreme™ Application?
Before we get started, you may find it helpful to review an overview of the Voice Extreme System. (If you just
want to get going, you can safely skip to Creating Your First Voice Extreme™ Project). A Voice Extreme™
application consists of a program file plus any data files it needs, linked together into a binary image file that
can be downloaded to a 2Mbyte flash data memory. This program is then executed by the Voice Extreme™
interpreter, which runs in program memory built in to the VE IC.
Please refer to the Voice Extreme Manual for a more detailed explanation and example code.
Voice Extreme™ data files are described in detail in the “Voice Extreme™ Data Files” section of the Help
file. They consist of:
Speech synthesis files, also known as vocabulary tables (.VES file)
Speech sentences files (.VEO files)
Weights files, for use with Speaker Independent recognition (.VEW file)
Notes and tunes files, for use with the Music technology (.VEM file)
Most programs begin with a series of statements that define, and optionally initialize, the data used by the
program. VE-C allows both standard C data types and built-in data types specifically designed for use with
the Sensory technologies.
Data types used by Voice Extreme™ applications include:
Integers for use as counters, indices, error codes
Characters and strings of characters for messages
Boolean, or true/false, variables to control program flow
Templates (and arrays of templates) for use with Sensory recognition
Built-in Sensory data types (SPEECH, SENTENCES, WEIGHTS, NOTES, TUNES) contained in data
files and linked together with Voice Extreme™ programs
The data declarations are followed by a series of control statements that define the program flow. The Voice
Extreme™ language, VE-C, is very similar to ANSI-standard C.
The following types of statements are available:
Assignment of values to variables
Arithmetic and logical operations on variables
Looping (for, while, do…while)
Branching (if…else, switch…case, goto)
Calls to built-in functions that access Sensory technologies and system resources

Quick Start Manual
Creating Your First Voice Extreme™ Project
No C manual would be complete without a “hello world” example. We will build a sample application that
speaks “hello world” and runs on the Voice Extreme™ Toolkit.
To build our application:
Create a document
Create a project
Build the project
Download the project to flash memory on the VE module
Note that we need a vocabulary containing one phrase, “hello world”. For this example, Quick Synthesis™
was used to produce a speech file, “hello.ves”. This file contains the label “VPhelloworld”, which allows our
program to link to it.
Creating a ‘Hello World’ Program
Using the editor, we first create a document and save it:
Go to "File", "New" then “Empty document” (CTRL-N) or press the
An "untitled.vec" document will be created.
Enter the following text:
button.
/* My first Voice Extreme program */
extern SPEECH VPhelloworld;
// Label or address of speech data
main ()
{
Talk(0, &VPhelloworld);
// Say “hello world”
}
Save it by pressing the
button on the editor toolbar, using “hello” as a file name (the extension will be
added automatically).
The file “hello.vec” will be created.
Creating the Project
To generate the binary file, we need to create a project that contains the document, and then add any data
files required for linking.
Go to "Project" then "New".
A document named "untitled.vep" will be created, and the project window will be opened.
Add the document to the project by pressing the
button.
Add the speech file “hello.ves” by pressing the
button; the file is located in the “samples\data\speech”
folder.
Change the project description, if you like.
Save the project. Go to “Project”, then “Save” and use “hello” as a file name (the extension will be added
automatically). A file named “hello.vep” will be created.
Building the Project
At this point, we can compile our document and link it with the vocabulary file to produce a binary image in
“hello.veb”.
Go to “Project”, then “Build” or press the
button.
The "Build process" box will show each step performed by the builder, reporting any errors (shown in
red). The blue progress bar provides an estimate of the remaining time to complete the build.
At the end of the build process, the program makes a single beep and the "Build progress" box reports:
"BUILD PROCESS OK”. If there are any errors, the text in the "Build progress" box turns red, and an
error message will be reported.

Downloading
After a successful build, the binary image file is generated, in this case “hello.veb”. Now you are ready for
the “Download” process.
Go to “Project” then “Download” or press the
button.
The "Download process" box will show each step performed by the programmer, reporting any errors
(shown in red). The blue progress bar provides an estimate of the remaining time.
At the end of the download process the program makes a single beep, and the download progress box
reports: "DOWNLOAD PROCESS OK".
If there are any errors, the text in the build progress box turns red and an error message will be
reported.
The application is now stored in non-volatile memory in the module, allowing us to turn it off and on, saying
“hello world” every time.

Quick Synthesis™
The Sensory Quick Synthesis™ tool is designed to help create and manage speech synthesis for Voice
Extreme™ and other Sensory RSC microcontroller applications. The process can be done quickly and
without the use of a Sensory linguist. However, audio files created with Quick Synthesis™ will have
somewhat lower quality sound and will require more memory than those created by Sensory. Its important to
note that speech files created by Quick Synthesis™ must be 64 Kbytes or less. If your project requires more
than 64 KBytes of speech, please create several smaller files.
Quick Synthesis™ is often used to generate speech synthesis for prototypes or moderate volume
production, where development time and cost must be minimized. Once a product goes to production,
Sensory-processed files can be generated to yield the highest audio quality, while minimizing the amount of
required
memory.

Voice Extreme™ Toolkit
Quick Start Manual
Creating Your First Quick Synthesis™ Project
To create synthesis files:
1. Go to "File", then "New" or press the
button.
2. An "untitled.qsp" project will be created.
3. A description of the project can be entered into the window on the right side of the file list. Your
description will be saved in the project file.
Adding Files to the Project
1. Go to "Edit" then "Add Wav file" or press the
button.
2. Select the files you would like to add (multiple files can be selected) and click "OK". The selected
files will be added to the project list.
3. If you need to adjust the volume of your sound files, slide the volume control bar to the left or right,
depending on how much the amplitude needs to be raised or lowered (in percentages). The value
will be applied to all selected files. This allows you to regulate the volume of individual files. It is also
possible to compare the levels by selecting the files and clicking on the option “Play” in the “Editing”
menu or by pressing the
button. The files will be played sequentially and the volume will be
adjusted according to the value of each file.
Note that the format of the .wav files must be mono, 22050 Hz, 16 bits. If a selected file does not conform
to this format, an error message will be generated. You can’t override this error so it is recommended that
you convert the format using your preferred .wav editor.
Editing the Project
Add the files in the order you would like them listed, or change their position in the list with the "move up" or
"move down" commands. A speech file may contain multiple speech fragments. The index number tells the
program which speech to play. The first wave file in your project list will have an index number of zero. The
second wave file will have an index number of one, and so on.
To do this go to "Edit" then "Move up"/"Move down" or press the
buttons. Alternatively, you can select
and move a group of files. If you need to remove a file from the list, select it and go to "Edit", then "Remove"
or press the
button. It is also possible to select and delete a group of files.
Setting Project Options
Silences
). Selecting this option will add ten predefined silences to the
Decide if you want to add silences (press
output files. The silence durations are as follows: 20ms, 40ms, 75ms, 100ms, 160ms, 200ms, 400ms,
800ms, 1600ms, 3200ms. This will add approximately 50 bytes to the project file.
Compression
Select compression preferences (choose from "Compression" list). Select the amount of compression you
wish to apply to the speech synthesis. The compression ratios are approximately as follows:
2-Bit: 2700 bytes/second
3-Bit: 3400 bytes/second
4-Bit: 4100 bytes/second
The compression level chosen will depend on the available memory for speech synthesis data and the
desired speech quality. If, during the build process, the program calculates that the <ProjectName>.ves file
will exceed 64Kbytes, it will inform you of this and allow you to abort or proceed anyway with the build. 4-bit
compression will take up the most space, but it will give you the best quality synthesis. A good
approximation for 2-bit memory space is that 12 seconds of sound at 2-bit compression will use 32Kbytes of
memory. Voice Extreme has a 2 Mbits (256 Kbytes) Flash, which is broken into four banks of 64 Kbytes. So,
if your speech file is larger than 64 Kbytes, you need to create an additional speech file and link it to your
project.

Platform
Select your platform (choose from the "Platform" list). Select the format for the output files here. The first
option (RSC-3x) is for RSC-3x assembly language applications. The second option (Voice Extreme) is for
Voice Extreme™ applications.
Label
Choose a label for your project (input label in "Label" box). This is the label that will be used in the final
assembly language or VE-C application to refer to the starting address of the speech synthesis file. This
speech label has to be defined as an extern in the application code; otherwise you will get an error
message. Also, the speech file has to be linked with the project to avoid an “Unresolved External Symbol”
error message.
Note that some older versions of Quick Synthesis™ add a VP prefix in front of the label. Please visit
www.voice-extreme.com to download the latest copy of the software.
Building the Project
Projects must be saved before they can be built. The program checks if the project has been saved,
indicated by the "Save" button becoming active when the project needs to be saved.
Go to "File", then "Save" or press the
button. You should change the name from the default name
"untitled.qsp". Otherwise, at each attempt to save the project, you will be prompted to change its name.
For test purposes, use "MyProject" and a file will be created: MyProject.QSP.
Go to "Tools", then "Build project" (F9) or press the
button. You will be prompted to save if the
project has been modified since the last save, or if there are errors in the project configuration.
The build process starts and the "Build process" box will show each step performed by the builder,
reporting any errors (shown in red). The blue progress bar provides an estimate of the remaining time.
At the end of the build process the program makes a single beep, and the "Build progress" box reports:
"BUILD PROCESS OK”. If there is an error, the text in the "Build progress" box turns red and an error
message will be reported.
Note that the duration of the build process can vary from a few seconds to several minutes, depending on
the number of files contained in the project. The process can be interrupted by pressing the “Stop” button
. To close the build window, press the “Exit” button .
The builder will create two output files:
MyProject.ves is the speech file that can be added to your Voice Extreme™ project.
MyProject.veh is a file that can be included in a Voice Extreme™ source file. It contains information
about the speech, such as the index number.

a .VEO object file. Sentence tables typically contain a label starting with “SN”. The “\sample\speech” folder
contains a few source files as well as corresponding object files.
There are seven main components that are required to create a sentence table file.
1. Define the speech file(s) as an external component. Example:
extern VPsddemo
extern VPsensopow
extern VPhelloworld
2. Define the sentence table label as a public label, allowing the Voice Extreme program to access the
sentence table. Example:
public SNtest
3. Include the sentence table definition. This is required because most of the definitions and macros
used in a sentence table file are defined in the sentable.inc file. Example:
include "sentable.inc"
4. Name the sentence label segment and define the label. Example:
_SNtest segment "CDATA"
SNtest:
; Name the segment beginning with “_”
; Sentence Table starts with Speech Table List
5. Define the label, add the number of speech files and list the speech file labels. A sentence table
supports up to 30 speech files. The number of speech files should be preceded by a db. The labels
for the speech file should preceded by a “dt”. Example:
db
dt
dt
dt
3
VPsddemo
VPsensopow
VPhelloworld
;
;
;
;
3=number of speech files
0=sddemo phrases
1="Sensory powered"
2="Hello World"
Note: Comments are preceded with a semicolon.
6. Define the number of sentences to be created and create the actual sentence strings. Example:
db 7
; M=number of sentences, maximum=255
SpeechTable 0
; use speech table 0=VPsddemo
db 21, EOM
;1:“Beep” is word 21 in VPsddemo
; EOM = End of sentence token
SpeechTable 0
db 21, 21, EOM
;2:“Beep” “Beep”
SpeechTable 0
; use speech table 0=VPsddemo
db 13, MSIL, 34, 1, EOM
;3:“say” MSIL “word” “one”. MSIL=75mS silence
SpeechTable 0
db 13, MSIL, 34, 2, EOM
;4:“say” MSIL “word” “two”
SpeechTable 0
db 13, MSIL, 34, 3, EOM
;5:“say” MSIL “word” “three”
SpeechTable 2
; use speech table 2=VPhelloworld
db 0, EOM
;6:“Hello World”
SpeechTable 1

Voice Extreme™ Development Board
The Voice Extreme™ Development board is the larger of the two circuit boards in the Voice Extreme™
Toolkit, and provides a convenient means of interfacing the Voice Extreme™ Module with the development
PC, as well as many handy “accessory” functions.
The Development Board offers several features:
Speaker
The onboard speaker has a fixed volume and is intended for application debugging. For better audio quality,
use of an external speaker with adjustable volume is recommended. Plugging an external speaker into the
speaker jack will disable the onboard speaker.
Prototyping Area
A grid of 0.1” through-holes for use by the application developer to add external circuitry.
RS-232 Port
A 9-pin connector for connecting the serial cable to the development PC.
I/O Port
A standard 20-pin shrouded header with 0.1” centers for wiring the I/O lines from the development board to
the target application. The I/O pins are initially assigned and configured as:
I/O

If an application is stand alone, the two serial I/O pins, P0.0 and P0.1, and the serial port enable, P1.7, may
be used for other purposes; however, programs will download via asynchronous serial I/O. Since I/O pins
P0.5 and P0.6 are connected to the address bus of the Flash memory, they should not be used under any
circumstances.

Voice Extreme™ Module
The Voice Extreme™ (VE) module is the heart of the Voice Extreme™ system, and is intended to be
removed from the Development Board and wired into the target application.
The VE module offers several features:
Mounting Hole
Four mounting holes are provided for secure mechanical connections in mounting the module in an
application. When the module header connector is used to connect the module to another board, the
mounting holes are normally not required.
Module Connector
A standard header with 0.1” centers to carry signals between the Development Board and the Voice
Extreme™ module. See the Interfaces section for a pinout table of this connector.
VE IC
The Voice Extreme™ Integrated Circuit (VE IC) is the central speech processor. Please refer to the Voice
Extreme™ IC Datasheet for a detailed specification.
VE ROM
This 64KB OTP ROM contains the VE interpreter and the speech technology code. If the VE IC is purchased
from Sensory, the VE interpreter and speech technology code are masked into an internal ROM on the VE
IC. In this case, the external ROM is not required.
Microphone Gain Resistor
An optional microphone resistor may be added to the VE module. From the factory, the microphone gain is
pre-set to a level suitable for arms-length user interfaces. An application note is available for selecting a gain
resistor for other applications.
Osc 1 Crystal
A 14.318 MHz crystal used to establish the frequency of Timer 1 on the VE IC. Timer 1 is used for all speech
recognition functions.
Osc 2 Crystal
A 32.768 KHz crystal used to establish the frequency of Timer 2 on the VE IC. Timer 2 is useful for
timekeeping applications since it is not interrupted, unlike Timer 1.
Note that Timer 2 is not available on the TQFP versions of the VE IC.
2MB Flash Memory
This memory is required on the VE module and all VE applications. Due to the powerful dynamic memory
handler of VE system software, this Flash is designed to store the application code, speaker independent
weight sets, speech templates, record and playback data, program data, and music data.
Voice Extreme™ Module Connector
A standard 34-pin header with 0.1" centers to carry signals between the Development Board and the Voice
Extreme™ module. This header has pins on 0.1” centers, and interfaces the VE module with the
Development Board. It is referenced as J3 on the Development Board and J1 on the VE Module.

Now What?
Adding the VE Module to Your Product
Always check out www.voice-extreme.com for the latest news on the Voice Extreme line of products. While
documentation in the program help is current at the time of shipping, it is always best to check our web site
for the latest information. You will also find software updates, sample applications and useful application
notes.
System Design Issues
If the module is used in a system with other digital clocks (switching power supplies, LCD drivers, etc.) take
special care to prevent these signals from being coupled into the audio circuitry of the VE module. Using a
shielded cable for the microphone connection will also reduce noise in the audio path.
With proper product construction, the module will meet the CE requirements for electromagnetic radiation
and immunity. To minimize radiated emissions, speaker wires should be less than 3” long. In addition, the
speaker cable and power cable should be oriented on opposite sides of the module.
Microphone Considerations
For most applications, an inexpensive omni-directional electret capacitor microphone with a minimum
sensitivity of -60 dB is adequate. In some applications, a directional microphone might be more suitable if
the signal comes from a different direction than the audio noise.
Since directional microphones have a frequency response that depends on their distance from the sound
source, such microphones should be used with caution. For best performance, speech recognition products
should be used in a quiet environment with the speaker’s mouth in close proximity to the microphone.
Important mechanical issues pertaining to microphone assembly:
FIRST: In the product, the microphone element should be positioned as close to the mounting surface as
possible and should be fully seated in any housing. There must be NO air space between the
microphone element and the housing. Having such an air space can lead to acoustic resonance,
which can reduce recognition accuracy.
SECOND: The area in front of the microphone element must be kept clear of obstructions to avoid
interference with recognition. In general, the diameter of the hole in the housing in front of the
microphone should be at least 5 mm. Any necessary plastic surface in front of the microphone should
be as thin as possible, no more than 0.7 mm.
THIRD: The microphone should be acoustically isolated from the housing if possible. This can be
accomplished by surrounding the microphone element with a spongy material such as rubber or
foam. Mounting with a pliable, non-hardening adhesive is another possibility. The purpose is to
prevent auditory noises produced by handling or jarring the product from being “picked up” by the
microphone. Such extraneous noises can reduce recognition accuracy.

The Interactive Speech™ Product Line
The Interactive Speech line of ICs and software was developed to “bring life to products” through advanced
speech recognition and audio technology.
The Interactive Speech Product Line was designed for consumer telephony products and cost-sensitive
consumer electronic applications such as home electronics, personal security, and personal communication.
The product line includes award-winning RSC series general-purpose microcontrollers and tools, SC series
of speech microcontrollers, plus a line of easy-to-implement chips that can be pin-configured or controlled by
an external host microcontroller. Sensory’s software technologies run on a variety of microcontrollers and
DSPs.
RSC Microcontrollers and Tools
The RSC product line contains low-cost 8-bit speech-optimized microcontrollers designed for use in
consumer electronics. All members of the RSC family are fully integrated and include A/D, preamplifier, D/A, ROM, and RAM circuitry. The RSC family can perform a full range of speech/audio
functions including speech recognition, speaker verification, speech and music synthesis, and voice
record/playback. The family is supported by a complete suite of evaluation tools and development kits.
SC Microcontrollers and Tools
The SC-6x product line features the highest quality speech synthesis ICs at the lowest data rate in the
industry. The line includes a 12.32 MIPS processor for high-quality low data-rate speech compression and
MIDI music synthesis, with plenty of power left over for other processor and control functions. Members of
the SC-6x line can store as much as 37 minutes of speech on chip and include as much as 64 I/O pins for
external interfacing. Integrating this broad range of features onto a single chip enables developers to create
products with high quality, long duration speech at very competitive price points.
Application Specific Standard Products (ASSPs)
Voice Direct™ 364 provides inexpensive speaker-dependent speech recognition and speech
synthesis. This easy-to-use, pin-configurable chip requires no custom programming and can
recognize up to 60 trained words in slave mode, and 15 words in stand-alone mode. Ideal for
speaker-dependent command and control of household consumer products, Voice Direct 364 is part
of a complete product line that includes the IC, module, and Voice Direct 364 Speech Recognition
Kit.
Voice Extreme™ simplifies the creation of fully custom speech-enabled products by offering
developers the capability of programming the chip in a high-level C-like language. Program
code, speech data, and even record and playback information can be stored on a single offchip Flash memory. Based on Sensory's RSC-364 speech processor, Voice Extreme
includes a highly efficient on-chip code interpreter, and is supported by a comprehensive
suite of low-cost development tools.
