ABSTRACT:
The invention relates to a method and an apparatus for improving the responsiveness and accuracy of speech recognition systems with tightly integrated Automatic Speech Recognition (ASR) and voice resources, more particularly to a system and method for providing an improved speech recognition enhanced user interface through a reduction in the effective talk-over period. The speech recognition system comprises a host server, managing and arbitrating between a voice resource and an ASR resource, among other resources, through the exchange of run-time controls. The novel method provides for a daisy chain architecture within the speech recognition system, whereby the voice data, or prompt, output by the voice resource is passed directly to the ASR resource, where it is output to the system user. Upon detection of speech from the user, the ASR resource stops transmitting the prompt to the system user, transparent to both the voice resource and the server, followed by a "speech detected" message sent to the server. The delay between the time at which the speech is detected and the time at which the voice resource stops playing the prompt, as a result of a "stop play" request received from the server, goes unnoticed by the system user due to the ASR resource intervention.
