Language Identification is the task of identifying a language from a given spoken utterance. Main task of a language identifier is to design an efficient algorithm which helps a machine to identify correctly a particular language from a given audio sample. We have proposed here a hybrid approach for identifying a language which is a combination of Vector Quantization (VQ) and Gaussian Mixture Models (GMM). A brief review of work carried out in the area of Speaker Identification using VQ-GMM hybrid approach is discussed here. We have carried out experiments for identifying four Indian Languages--Assamese, Bengali, Hindi and Indian English. The experiments were carried out on our own recorded standard language database collected from 50 speakers. Speech features were extracted using MFCCs. Results show that after applying hybrid approach, accuracy is best with highest mixture order and with the increase in mixture order, accuracy increases uniformly for all four languages. It is also concluded here that hybrid approach gives better results when compared with the baseline GMM system.
