Overlapping phone segments

Z. Li, P. Kenny

We present a new approach to acoustic-phonetic modelling in which the acoustic segments which correspond to the phones in a given phonetic transcription are allowed to overlap with each other. We show how any type of phone segment model including conventional HMMs can be accommodated in this framework by matching transcriptions to data in a phone-synchronous rather than the conventional frame-synchronous manner. We present a new and efficient algorithm which can be used to carry out phone-synchronous scoring with overlapping phone segment models in both training and recognition. We give some preliminary experimental results obtained using conventional HMMs to model overlapping phone segments.
