Abstract

In this proposal, we propose a novel handheld system to automatically identify the current speaker and recognize his/her speech. The system consists of several parts. First, the acoustic signal collected by the commercial off-the-shelf array microphone is first passed through the state machine based speech segmentation module to extract the speech segments. The speech segments are then enhanced by speech enhancement module to compensate the channel distortion and background noise. The enhanced speech is then fed to speaker identification and speech recognition modules. For each recognizable speaker, the speaker adaptation module is continuously adapting its models for both speaker identification and speech recognition.
