Speech Recognition and Synthesis Technologies on Bluetooth™ Chipset for In-Car Use

Toshiba has developed high-performance, smallfootprint speech recognition and synthesis middleware on a Bluetooth™ chipset for an in-car hands-free communication system.

The speech recognizer achieves highly accurate speaker-independent recognition capable of recognizing continuous digits such as telephone numbers as well as commands even in a noisy environment, while the speech synthesizer produces highly natural and intelligible speech. A grapheme-to-phoneme translator is also provided, which can automatically produce phoneme sequences from name entries in directory information.

With the use of a Bluetooth™-enabled cellular phone, these speech technologies enable car drivers to make hands-free calls easily and safely simply by saying a person’s name or telephone number such as “Call Bob” or “Dial 090 123 4567.”
