| Abstract: | Recently, speech recognition systems are in practical use as an input device of a car navigation system, etc. However, since the computational and storage resources are usually limited for a car navigation system, these systems are required to achieve high recognition performance with the limited resource. In this paper, we propose a method that reduces the components of full covariance matrix considering only the dominant correlation components between static and dynamic feature parameters. The recognition experiment was performed by using the conventional and the proposed method, and both were compared. From the continuous syllable recognition result, we confirmed the effectiveness of proposed component reduction technique considering the correlation between parameters. |
