Hybrid Approaches for Language and Lexical Modeling in Speech Recognition

Status

completed

Description:

The goal of this thesis is the improvement of automatic speech recognition for highly inflective languages with a complex grammar, like Russian or German.

Large vocabulary continuous speech recognition (LVCSR) of such languages with rich morphology is considered to be a challenging task. Augmenting the full-word language model by fragments is a well-proven approach targeting this challenge and capable of recognizing missing words in the lexicon (so called open vocabulary recognition). Within the scope of this research Russian LVCSR System is built and various hybrid approaches for Lexical and Language Modeling are investigated.
