| Abstract(in English) | We propose a speech recognition method under noisy environments using multiple microphones based on asynchronous and intermittent observations. In this method, microphones placed at various locations in the room sometimes observe sounds, and clustering by GMM is performed to model the noise in the environment. Each of the clustered noise spectrum is subtracted from the input signal, and then the noise-reduced signals are decoded in parallel. Then, the final recognition result is determined by integrating all of the recognition results. |
