In this paper, an m-level optimal subtree based phonetic decision tree clustering algorithm is described. Unlike prior approaches, the m-level optimal subtree in the proposed approach is to generate log likelihood estimates using multiple mixture Gaussians for phonetic decision tree based state tying. It provides a more accurate model of the log likelihood variations in node splitting and it is...

Standard phonological representations provide only a very coarse-grained specification of the phonetic properties of a word or phrase. That is, representation in terms of standard phonological features and timing units corresponds approximately to the level of detail contained in a broad phonetic transcription, and the representation of time is in many ways even more limited. For example, consi...

computer-assisted language learning (call) is reaching an up most position in the pedagogical field of english as a second or foreign language (esl/efl). the present study was carried out to study the effect of using phonetic websites on iranian efl students’ pronunciation and knowledge of phonemic symbols. participants of the study included 30 efl female pre-intermediate students studying in k...

A Conditional Random Field is a mathematical model for sequences that is similar in many ways to a Hidden Markov Model, but is discriminative rather than generative in nature. In this paper, we explore the application of the CRF model to ASR processing of discriminative phonetic features by building a system that performs first-pass phonetic recognition using discriminatively trained phonetic f...

This paper describes the development procedure of three different Bangla read speech corpora which can be used for phonetic research and developing speech applications. Several criteria were maintained in the corpora development process that includes considering the phonetic and prosodic features during text selection. On the other hand, a specification was maintained in the recording phase as ...
