Spoken Language Identification (SLI) is the process of identifying the language spoken by a speaker. Language identification has several applications in day-today life. It may be used in call centers (e.g., emergency and customer services), information directories (e.g., airport, hotel, and tourist attractions) dealing with speakers speaking different languages[1]. Humans perform language identification mainly based on the specific words(phonetic information) and pattern of pronunciation. Spectral features are known well to capture phonetic information from the speech utterances[2]. Therefore, in this work MFCC’s(Mel Frequency Cepstral Coefficients) are used. Language identification is mainly done using some pattern classifier namely GMM, SVM, ANN and HMM[3].
