Analysis of the Possibilities to Adapt the Foreign Language Speech Recognition Engines for the Lithuanian Spoken Commands Recognition

摘要

This paper presents our activities trying to adapt the foreign language based speech recognition engine for the recognition of the Lithuanian speech commands. The speakers of less popular languages (such as the Lithuanian) have several choices: to develop own speech recognition engines or to try adapting the speech recognition models developed and trained for the foreign languages to the task of recognition of their native spoken language. The first approach is expensive in time, financial and human resources sense. The second approach can lead to the faster implementation of the Lithuanian speech recognition modules into some practical tasks but the proper adaptation and optimization procedures should be found and investigated. This paper presents some of our efforts trying to adapt the foreign language oriented speech recognition engines for the recognition of the Lithuanian speech commands for the speaker-independent applications. The experimental investigation shows that the promising results could be achieved with relatively modest investments.
