Abstract: In this paper, recognising the speaker in the multilingual context is demonstrated. Multilingual speaker recognition is useful in countries like India, Canada and South Africa where multiple languages are used for communication. In such countries, use of the monolingual speaker recognition system may not yield the expected level of performance. This is because a speaker may change his training and test languages whenever it is necessary. As a result, the system yields poor performance due to variation in language parameters. Therefore, developing a robust multilingual speaker recognition system is an issue in many countries. Researchers in the field of speaker recognition have made a few attempts to identify the speaker in a multilingual context. This paper gives an overview of various techniques developed for monolingual, cross-lingual and multilingual speaker recognition systems.

Keywords: speaker recognition; monolingual speakers; cross-lingual speakers; multilingual speakers; feature extraction; modelling; multiple languages.
