Research Abstract

For speech recognition, in a large vocabulary task, any phone sequence didn't induce statistically significant deficient performance without contribution of language models. For speaker recognition/verification, on the other hand, it seems to be difficult other than increasing of training data. Most applications of speaker recognition, it cannot be expected sufficient training data. Moreover, it is difficult to assume a target phone sequence in advance. Therefore, a new method is required for speaker recognition, because many previous methods for improving speech recognition cannot be efficient for speaker recognition.
