Abstract(in English) | This paper proposes a speech recognition strategy to deal with utterances having unregistered words. The strategy integrates unregistered-word detection using phoneme cluster Hidden Markov Models (HMMs) and registered-word recognition using phoneme HMMs. These phoneme cluster models are designed to minimize both the increase in processing for unregistered words and the decrease in the recognition performance for registered words. A further goal is to maximize the detection performance of unregistered words. In sentence recognition experiments using this unregistered-word processing, the proposed cluster models that achieved the best word accuracy of 70.3%, compared with 58.1% for sentence recognition without this processing. The processing using the cluster models is the half computation and perform as well as phoneme models. We confirmed the effectiveness of this strategy. |
