Phonetic segmentation: unsupervised approach
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Phonetic segmentation can find its potential application for Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) Synthesis systems. In this thesis, we propose use of different spectral features viz., Mel Frequency ...
Vocal tract length normalization for automatic speech recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Various factors affect the performance of Automatic Speech Recognition (ASR) systems. In this thesis, speaker differences due to variations in vocal tract length (VTL) are taken into account. Vocal Tract Length Normalization ...
