Adding speech and voice recognition to any product made easy

21 September 2005 Electronics Technology

With Sensory's new VR Stamp, you can now add voice recognition, speech output, and music synthesis to any product imaginable, according to the company.

The VR Stamp is the first rapidly deployable speech module to use Sensory's proprietary Quick T2SI (text to speaker independent) technology, which allows developers to create working recognition sets in minutes. Multiple languages are supported, making it useful for products worldwide. Based on Sensory's RSC family of microcontrollers, the VR Stamp is a completely modularised, production-ready speech recognition system that allows products to speak and hear with minimal development time and 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 standardised packaging allow rapid prototyping, less debugging and shorter time to market. It offers 24 I/O lines, as well as connections for a power, ground, microphone, speaker, and logic-level RS232 interface. The VR Stamp has low power requirements: 2,7 V-3,6 V, IACT = 26 mA @ 3 V, and less than 20 μA in sleep mode. Many language models are now available for international use.

The VR Stamp Toolkit is a development platform that contains everything necessary to program the VR Stamp to one's specifications. Application programs are downloaded onto the module using a VR Stamp 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.
