| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Simulation of language acquisition processes is an active research area in speech and computer science. Here, models and hypotheses proposed in developmental psychology play important roles. Problems addressed in simulation studies may be broadly classified into two categories: (1) How to segment a continuous speech stream into words? (2) How to normalize the acoustic features that vary based on speaker and environment? The main focus of this study is put on the second problem. In our previous studies, we proposed a new speech modeling technique, called speech structures, where the non-linguistic aspect of speech is cancelled well from speech acoustics and only the linguistic aspect is represented in the model. In this study, by considering infants' good sensitivity to rhythmic structure of language, automatic detection of syllable nuclei are technically implemented using waveform envelopes. Then, the detected nuclei are used in the matching module of a structure-based word recognition system. Results show that the validity of using the syllable nuclei to improve the performance. | |
