Abstract:
According to one embodiment, a sound processing apparatus extracts a feature of first speech uttered outside an objective area from first speech obtained at positions different from each other in a space of the objective area and a place outside the objective area. The apparatus creates, by learning, a determination model configured to determine whether an utterance position of second speech in the space is outside the objective area based at least in part on the feature uttered outside the objective area. The apparatus eliminates a portion of the second speech uttered outside the objective area from the second speech obtained by a second microphone based at least in part on the feature and the model. The apparatus detects and outputs remaining speech from the second speech.

Claim (Index 8):
A method of speech recognition, the method comprising:\n arranging a plurality of first microphones at positions different from each other in a space comprising an objective area and a place outside an objective area; extracting a feature of first speech uttered outside the objective area from first speech obtained by the plurality of first microphones; creating, by learning, a determination model configured to determine whether an utterance position of second speech is outside the objective area based at least in part on the feature of the first speech uttered outside the objective area; arranging a second microphone in the space; eliminating a portion of the second speech uttered outside the objective area from the second speech obtained by the second microphone based at least in part on the feature and the determination model; detecting remaining speech from the second speech; and recognizing contents of the remaining speech.
