The objective of Spoken Language Identification (LID) is to recognize automatically the language spoken in an unknown speech signal. This system has several applications such as Speech-To-Speech Machine Translation Systems and telephone-based services. In the case of Automatic Speech Recognition (ASR), the LID allows the selection of appropriate parameters of the ASR system. There are two main types of LID system: there are LIDs based on spectral features and others based on tokens.
