Speech processing apparatus, method, and program

A speech processing method comprising:

• recognizing speech from an air microphone acquiring speech through air,
• recognizing speech from a wearable microphone,
• measuring environmental conditions including at least a distance between the air microphone and a speaker,
• calculating weights for results of recognizing the speech from the air microphone and from the wearable microphone on the basis of the environmental conditions, and
• combining the results of recognizing the speech from the air microphone and from the wearable microphone, using the weights,
• wherein the weight for the results of recognizing the speech from the wearable microphone is determined in accordance with the distance between the air microphone and the speaker, and
• wherein the weight for the results of recognizing the speech from the wearable microphone is a monotonically non-decreasing function, with respect to the distance between the air microphone and the speaker.

A non-transitory computer readable information recording medium storing a speech processing program, when executed by a processor, executes:

• recognizing speech from an air microphone acquiring speech through air,
• recognizing speech from a wearable microphone,
• measuring environmental conditions including at least a distance between the air microphone and a speaker,
• calculating weights for results of recognizing the speech from the air microphone and from the wearable microphone on the basis of the environmental conditions, and
• combining the results of recognizing the speech from the air microphone and from the wearable microphone, using the weights, w
• herein the weight for the results of recognizing the speech from the wearable microphone is determined in accordance with the distance between the air microphone and the speaker, and
• wherein the weight for the results of recognizing the speech from the wearable microphone is a monotonically non-decreasing function, with respect to the distance between the air microphone and the speaker.
