An embedded system for speech recognition compression

With the success of Uni-Speech chip designed for advance speech recognition system, there is an effort to develop a cost efficient version of the Uni-Speech chip targeted for mass consumer market speech-recognition related applications with special focus in improving power consumption. In this paper, a new low cost speech device called UniSpeech-Lite is described. The UniSpeech-Lite is an integrated SoC (system on chip), containing the speech functions for prompt, record, speaker-independent voice recognition, suitable for many applications such as portable speech related educational devices, toys, digital recorder, voice based remote control, etc. UniSpeech-Lite is specifically targeted for stable performance, low cost and low power-consumption. This chip will enable extensive deployment of applied speech technology in many fields and achieve favorable economic and social benefits.
