Plasticity in Systems for Automatic Speech Recognition: A Review
نویسندگان
چکیده
Although the topic ‘plasticity in speech perception’ is primarily concerned with the malleability of human speech perceptual behaviour, it may be illuminating to consider in parallel the degree to which current state-of-the-art ‘automatic speech recognition’ (ASR) systems also change their behaviour over time. This paper provides a review of the computational mechanisms underlying contemporary ASR systems with a particular focus on their adaptive and learning behaviour. It is shown how such systems can change dynamically in order to accommodate new speakers, handle unexpected user behaviour and track and compensate for constantly varying acoustic environments.

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...
