DISTRIBUTED SPEECH RECOGNITION WITH BACK-END VOICE ACTIVITY DETECTION APPARATUS AND METHOD |
摘要 |
In a distributed voice recognition system, a back-end pattern matching unit (27) can be informed of voice activity detection information as developed through use of a back-end voice activity detector (25). Although no specific voice activity detection information is developed or forwarded by the front-end of the system, precursor information as developed at the back-end can be used by the voice activity detector to nevertheless ascertain with relative accuracy the presence or absence of voice in a given set of corresponding voice recognition features as developed by the front-end of the system. |
