Speaker Non-speech Event Recognition with Standard Speech Datasets

Distributed Speaker Recognition Using the ETSI Distributed Speech Recognition Standard

Biometrics is gaining strong support for the personalization of and the securing of mobile devices. It is not uncommon for individual users to be faced with a half-dozen or more passwords and personal identification numbers. The ubiquity of passwords actually relaxes system security since many users tend to use the same password across all applications, or collect the various passwords in a sin...

Speaker Independent Speech Recognition Using Hidden Markov Models for Persian Isolated Words

Speaker Adaptation in Continuous Speech Recognition Using MLLR-Based MAP Estimation

A variety of methods are used for speaker adaptation in speech recognition. In some techniques, such as MAP estimation, only the models with available training data are updated. Hence, large amounts of training data are required in order to have significant recognition improvements. In some others, such as MLLR, where several general transformations are applied to model clusters, the results ar...

Speaker Independent Speech Recognition with Neural Networks and Speech Knowledge

Regis Cardin Dept Computer Science McGill University We attempt to combine neural networks with knowledge from speech science to build a speaker independent speech recognition system. This knowledge is utilized in designing the preprocessing, input coding, output coding, output supervision and architectural constraints. To handle the temporal aspect of speech we combine delays, copies of activa...

Speaker Recognition with Mismatched Coded Speech

This paper investigates the effects of low-bit rate coded speech on the performance of a fixedtext speaker recognition system, under mismatched coding conditions between enrollment and testing. Significant degradation of performance has been observed relative to matched conditions, where same coding is used. Two techniques have been proposed to overcome mismatch effects; a linear discriminative...
