Introduction,ssue in applications such as speech-to-speech translation devices or speech dialog systems..The pronunciation of non-natives deviates from native speech, leading to insertions, deletions and especially substitutions of sounds. The accent pattern depends mainly on the mother tongue of the speaker, ph

Automatic Speech Recognition,ction mechanism. An ASR system aims to infer those original words given the observable signal. The most common and as of today best method is the probabilistic approach. A speech signal corresponds to any word (or sequence of words) in the vocabulary with a certain probability.

We also summarize existing non-native speech databases and a provide classification into database types, explain their limitations and the importance of collecting our own database. All importan

Section 6.3 gives a brief outlook into automatic scoring of non-native speakers pronunciation and mispronounced word detection, comparing
