Early recognition of speech
Classic research on the perception of speech sought to identify minimal acoustic correlates of each consonant and vowel. In explaining perception, this view designated momentary components of an acoustic spectrum as cues to the recognition of elementary phonemes. This conceptualization of speech perception is untenable given the findings of phonetic sensitivity to modulation independent of the ...
متن کامل‘early Recognition’ of Words in Continuous Speech
In this paper, we present an automatic speech recognition (ASR) system based on the combination of an automatic phone recogniser and a computational model of human speech recognition SpeM that is capable of computing ‘word activations’ during the recognition process, in addition to doing normal speech recognition, a task in which conventional ASR architectures only provide output after the end ...
متن کاملImproving the performance of MFCC for Persian robust speech recognition
The Mel Frequency cepstral coefficients are the most widely used feature in speech recognition but they are very sensitive to noise. In this paper to achieve a satisfactorily performance in Automatic Speech Recognition (ASR) applications we introduce a noise robust new set of MFCC vector estimated through following steps. First, spectral mean normalization is a pre-processing which applies to t...
متن کاملAutomatic Speech Recognition: A Shifted Role in Early Speech Intervention?
Although automatic speech recognition (ASR) has been used in several systems that support speech training for children, this particular design domain poses on-going challenges: an input domain of non-standard speech and a user population for which meaningful, consistent, and well designed automatically-derived feedback is imperative. In this design analysis, we focus on and analyze the differen...
متن کامل‘On-line Early Recognition’ of Polysyllabic Words in Continuous Speech
In this paper, we investigate the ability of SpeM, our recognition system based on the combination of an automatic phone recogniser and a wordsearch module, to determine as early as possible during the word recognition process whether a word is likely to be recognised correctly (this we refer to as ‘on-line’ early word recognition). We present two measures that can be used to predict whether a ...
