Tigal announced the VoiceGP family of products under its VeeaR brand of voice and speech recognition products. The product family consists of the VoiceGP module and two development kits with bundled development software. It combines all the hardware and software required for easy and cost effective development and implementation of speech synthesis and multi-language speaker independent and speaker dependent speech recognition capabilities to virtually any application, says the manufacturer.

The VoiceGP Module is based on Sensory's RSC-4128 mixed signal processor. Its 42x72mm footprint and two 28-pin connectors with 2.54mm pin spacing make the module breadboard friendly and suitable for prototype boards.

The module is capable of running the latest Sensory FluentChip core technology libraries which enable speaker dependent recognition in any language, speaker independent recognition (US/UK English, German, French, Italian, Spanish (Latin American), Japanese and Korean), speech, DTFM synthesis, speaker verification, and record and play.

The module has 512KB of Code/Const Flash, 512KB of serial data flash, 128KB external RAM, and enables full access to the I/O pins of the RSC-4X processor. It also features an expansion bus that allows fast SPI interface to MMC cards, five dedicated chip select outputs, two memory enable outputs and an 8-bit wide read-write memory bus.

The VoiceGP development kit includes the VoiceGP module and a development board that can be powered via USB, batteries or an external power supply. It also has an on-board USB / serial adapter and programmer, on-board microphone, selectable audio output (PWM or DAC with on-board amplifier), 4 push-button inputs and 4 LED outputs for demos and fast prototypes, and an SD/SDHC/MMC compatible socket for extended storage.

The bundled development software consists of an integrated development environment, a tool chain with VeeSee C language code translator, VeeSee integrated C pre-processor, resource compiler and linker and VeeLoader code downloader / flash programmer.

Sensory's FluentChip technology library (build tools and documentation) and Sensory's QuickSynthesis4 software for speech and audio compression are also included. The kit is also optionally available with a user license for Sensory's Quick T2SI software that allows quick development of speaker independent vocabularies from text-based input in multiple languages.

All software tools (except QT2SI), documentation and demo videos are available online as a free download at www.veear.eu.
