Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for language identification. In some implementations, speech data for an utterance is received and provided to (i) a language identification module and (ii) multiple speech recognizers that are each configured to recognize speech in a different language. From the language identification module, language identification scores corresponding to different languages are received, the language identification scores each indicating a likelihood that the utterance is speech in the corresponding language. A language model confidence score that indicates a level of confidence that a language model has in a transcription of the utterance in a language corresponding to the language model is received. A language is selected based on the language identification scores and the language model confidence scores.
