SPEECH RECOGNITION APPARATUS AND SPEECH RECOGNITION METHOD |
| 摘要 |
A speech recognition apparatus includes: a sound collection unit that collects a sound signal; a sound source localization unit that calculates a spatial spectrum from the sound signal that is collected by the sound collection unit and uses the calculated spatial spectrum to perform sound source localization; a speech zone determination unit that determines a zone in which a power of the spatial spectrum that is calculated by the sound source localization unit exceeds a predetermined threshold value based on a vehicle state; and a speech recognition unit that performs speech recognition with respect to a sound signal of the zone determined by the speech zone determination unit. |
