Continuous Speech Recognition from a Phonetic Transcription
A long-standing and widely accepted linguistic theory of speech recognition holds that natural spoken messages are understood on the basis of an intermediate representation of the acoustic signal in terms of a small number of phonetic symbols. The traditional linguistic theory is very attractive for several reasons. First, it provides a natural way to partition the process of communication by s...
متن کاملContinuous Speech Recognition from Phonetic Transcription
Previous research by the authors has been directed toward phonetic transcription of fluent speech. We have applied our techniques to speech recognition on the DARPA Resource Management Task. In order to perform speech recognition, however, the phonetic transcription must be interpreted as a sequence of words. A central component of this process is lexical access for which a novel method is prop...
متن کاملcontext dependent modeling in continuous speech recognition based on a persian phonetic decision tree
context-dependent modeling is a well-known approach to increase modeling accuracy in continuous speech recognition. the most common way to implement this approach is via triphone modeling. nevertheless, the large number of such models results in several problems in model training, whilst the robust training of such models is often hardly obtained. one approach to solve this problem is via param...
متن کاملAdapting phonetic decision trees between languages for continuous speech recognition
In a continuous speech recognition system it is important to model the context dependent variations in the pronunciations of phones. In this work we have attempted to build decision trees for modeling phonetic context-dependency in Hindi. The approach followed is to modify a decision tree built to model context-dependency in American English. The reason the decision trees turn out to be differe...
متن کاملPhonetic Modelling in the Philips Chinese Continuous Speech Recognition System
We have extended the Philips large vocabulary continuous speech recognition system towards Chinese On the way from our existing Western language technology to Mandarin the rst step was to build a suitable phonetic model This paper describes the development of our phonetic model excluding tones for Mandarin Chinese We will present a systematic comparison of three forms of sub syllabic units for ...
