| Abstract(in English) | This paper describes a phoneme boundary estimation method based on recurrent neural networks (RNNs). The proposed method only requires acoustic observations to accurately estimate segment boundaries. Experimental results showed that the proposed method could estimate segment boundaries significantly better than an HMM or an MLP (multi-layer perceptron) based method. Furthermore, we incorporated the RNN based segment boundary estimator into the HMM based and segment based recognition systems. As a result, we confirmed that (1) the usage of BRNN outputs was effective for improving the recognition rate and reducing computational time in an HMM based recognition system and (2) segment lattices obtained by the proposed methods dramatically reduce the computational complexity of segment model based recognition. |
