摘要
En 中文
This tutorial presents an overview of the progression of spoken language identification (LID) systems and current developments. The introduction provides a background on automatic language identification systems using syntactic, morphological, and in particular, acoustic, phonetic, phonotactic and prosodic level information. Different front-end features that are used in LID systems are presented. Several normalization and language modelling techniques have also been presented. We also discuss different LID system architectures that embrace a variety of front-ends and back-ends, and configurations such as hierarchical and fusion classifiers. Evaluations of the LID system are presented using NIST language recognition evaluation tasks.
