Speaker Adaptation is a technique which is used to improve the recognition accuracy of Automatic Speech Recognition (ASR) systems. Here, we report a study of the impact of online speaker adaptation on the performance of a speaker independent, continuous speech recognition system for Hindi language. The speaker adaptation is performed using the Maximum Likelihood Linear Regression (MLLR) transfo...

Matching algorithms have significant importance in speaker recognition. Feature vectors of the unknown utterance are compared to feature vectors of the modeled speakers as a last step in speaker recognition. A similarity score is found for every model in the speaker database. Depending on the type of speaker recognition, these scores are used to determine the author of unknown speech samples. F...

In this paper, a probabilistic speaker-class (PSC) based acoustic modeling method is proposed for taking into account speaker variability influence in HMM-based speech recognition systems. Firstly, within the context of speaker-class based speech recognition, an experiment is conducted to investigate the performance of speaker-class recognition based on hard-cut speaker clustering. Then, in the...
