| Abstract(in English) | Speeh recognition based on one-model of articulatory movement HMMs that are commonly applied to both speech recognition (SR) and speech synthesis (SS) is described. In a SR module, speaker-invariant HMMs are applied to recognize articulatory feature (AF) sequence. This paper focuses on our approaches in designing an optimal state configuration for accurate phoneme recognizer based on articulatory movement. We consider several strategies to improve Articulatory Feature (AF) based phoneme recognition and compare its performance. In the experiments on Japanese Newspaper Article Sentences (JNAS) utterances, the approach of separating short vowel and long vowel in 5-states HMM triphone models provides higher accuracy compared to other approaches. |
