VR STAMP™
WITH SERIAL EEPROM
VOICE RECOGNITION MODULE
With the VR Stamp™ from Sensory, you can now add voice
recognition, speech output, and music synthesis to any product
imaginable.
The VR Stamp is the first rapidly deployable speech module to use
Sensory’s proprietary Quick T2SITM (text to speaker independent)
technology, which allows developers to create working recognition
sets in minutes. Multiple languages are supported, making the VR
Stamp useful for products virtually anywhere in the world.
Based on Sensory's award-winning RSC Family of microcontrollers,
the VR Stamp is a completely modularized, production ready
speech recognition system that allows products to speak and hear
with minimal development time and low system cost.
VR Stamp simplifies the integration of speech recognition into products by combining all key components into a
small 40-pin DIP footprint module. A low-noise audio channel and standardized packaging allow rapid
prototyping, less debugging and shorter time to market. The VR Stamp offers 24 I/O lines, as well as
connections for a power, ground, microphone, speaker, and logic-level RS232 interface. With its small size, full
suite of development tools and Sensory's world-class FluentChip™ Technologies, the VR Stamp will change
the way you think about speech recognition.

VR STAMP DEVELOPMENT PLATFORM
The VR Stamp Toolkit contains everything necessary to program
the VR Stamp to your specifications. Application programs are
downloaded onto the VR Stamp module using a Module
Programmer Board that has been connected to a PC’s USB port.
The VR Stamp can then be removed and plugged directly into the
final product using an industry standard DIP socket.
The VR Stamp Toolkit includes samples and demos of key
Sensory technologies that make developing with speech easier
than ever. Tools like QuickSynthesisTM 4 allow recordings of
speech to be compressed quickly with the right combination of
size and quality. Phyton’s Assembler and Linker work together
with a limited-life C Compiler to provide a powerful development
and coding environment.
All of the world-class technologies in the FluentChip library are available for use on the VR Stamp, with the
exception of Record & Play due to memory constraints.
THE VR STAMP TOOLKIT ALLOWS YOU TO:
Download an application program from the PC to VR Stamp using the Module Programmer Board
Develop VR Stamp applications
Sample key Sensory speech technologies and Demo common speech applications
