Title:
PROCESSING SPEECH FROM DISTRIBUTED MICROPHONES
Document Type and Number:
WIPO Patent Application WO/2017/197312
Kind Code:
A3
Abstract:
A plurality of microphones are positioned at different locations. A dispatch system in communication with the microphones derives a plurality of audio signals from the plurality of microphones, computes a confidence score for each derived audio signal, compares the computed confidence scores. Based on the comparison, the dispatch system selects at least one of the derived audio signals for further handling, receives a response to the further processing, and outputs the response using an output device. The output device does not correspond to the microphone that captured the selected audio signals.
