Speech input apparatus, speech processing method, speech processing program, ceiling member, and vehicle
First Claim
1. A speech input apparatus comprising:
- a sound insulating block attached to a ceiling member in a vehicle, so that a planer surface of the sound insulating block is attached to the ceiling member and side surfaces of the sound insulation block are projected from the ceiling member;
a first microphone that is out of the sound insulating block and attached to one of the side surfaces of said sound insulating block or attached to the ceiling member in a vicinity of said sound insulating block, on a side close to a passenger of the vehicle, inputs a first sound mixture including a voice of the passenger and noise in the vehicle and outputs a first signal to a noise suppressor;
a second microphone that is out of the sound insulating block and attached to another of the side surfaces of said sound insulating block or attached to the ceiling member in the vicinity of said sound insulating block, on a side far from the passenger, inputs a second sound mixture including a voice of the passenger and noise in the vehicle and outputs a second signal to the noise suppressor; and
a first mechanism capable of retracting said sound insulating block to be stored in or above the ceiling member, so that said sound insulating block insulates propagation of sound between the first microphone and the second microphone when said sound insulating block is projected from the ceiling member, and said sound insulating block does not insulate the propagation of sound between the first microphone and the second microphone when said sound insulating block is stored in or above the ceiling member.

Abstract
An apparatus of this invention is directed to a speech input apparatus for obtaining a piece of high-quality speech with included noise reduced. The speech input apparatus includes a sound insulating block attached to a ceiling member in a vehicle, a first microphone that is attached to a side surface of the sound insulating block or the ceiling member in the vicinity of the sound insulating block on a side close to a passenger of the vehicle, inputs a sound mixture including the voice of the passenger and noise in the vehicle, and outputs a first signal to a noise suppressor configured to output an enhanced speech signal, and a second microphone that is attached to a side surface of the sound insulating block or the ceiling member in the vicinity of the sound insulating block on a side far from the passenger, inputs the noise in the vehicle, and outputs a second signal to the noise suppressor.
