Modelling pronunciation variation with single-path and multi-path syllable models: Issues to consider
In this paper, we construct context-independent single-path and multi-path syllable models aimed at improved pronunciation variation modelling. We use phonetic transcriptions to define the topologies of the syllable models and to initialise the model parameters, and the Baum-Welch algorithm for the re-estimation of the model parameters. We hypothesise that the richer topology of multi-path syll...
متن کاملMulti-path Syllable Models Based on Phonetic Knowledge
Recent research suggests that syllable-length acoustic models might be more appropriate for pronunciation variation modelling than the context-dependent phones that conventional automatic speech recognisers use. In this paper, we compare the recognition performance of two types of recognisers: a conventional recogniser that only uses triphones, and an experimental recogniser that employs a mix ...
متن کاملOn the Utility of Syllable-Based Acoustic Models for Pronunciation Variation Modelling
Recent research on the TIMIT corpus suggests that longer-length acousticmodels aremore appropriate for pronunciation variation modelling than the context-dependent phones that conventional automatic speech recognisers use. However, the impressive speech recognition results obtained with longer-length models on TIMIT remain to be reproduced on other corpora. To understand the conditions in which...
متن کاملContextual Word and Syllable Pronunciation Models
This work focuses on the evaluation of models of syllable and word pronunciations constructed automatically using the Broadcast News corpus of radio and television news reports. Previous work [4] introduced the concept of extended-length decision tree models; here I report on ASR-independent assessment of these models. This study also discusses integration of static and dynamic pronunciation ev...
متن کاملConstruction and analysis of multiple paths in syllable models
In this paper, we construct multi-path syllable models using phonetic knowledge for initialising the parallel paths, and a data-driven solution for their re-estimation. We hypothesise that the richer topology of multi-path syllable models would be better at accounting for pronunciation variation than context-dependent phone models that can only account for the effects of left and right neighbou...
