| Abstract(in English) | In spontaneous speech, word pronunciations vary more than in read speech, while only standard pronunciations in citation form are used in most Japanese recognition systems disregarding real pronunciation variations. To cope with pronunciation variations in spontaneous speech, it is important to build a pronunciation dictionary from real speech data. In this paper, we propose an automatic generation method of a pronunciation dictionary based on pronunciation networks which give the most plausible pronunciations (henceforth correct pronunciations). First, phoneme recognition results are taken as the correct pronunciations. Then pronunciation networks are trained using multi-layer perceptron neural networks to predict these correct pronunciations from the canonical symbol sequences. Finally, pronunciation dictionaries are automatically generated from the pronunciation networks. Experimental results on spontaneous speech show that the automatically-derived pronunciation dictionaries give consistently higher recognition rates and require less computational time for recognition than the conventional dictionary. |
