Zusammenfassung:	Noise suppression performance is enhanced by performing appropriate noise suppression suitable for an environment of noise. Noise dictionary data read out from a noise database unit on the basis of installation environment information including information regarding a type of noise, and an orientation between a sound reception point and a noise source is acquired. Then, noise suppression processing is performed on a voice signal obtained by a microphone arranged at the sound reception point, using the acquired noise dictionary data.
