摘要
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for recognizing speech in an utterance. The methods, systems, and apparatus include actions of receiving an utterance and obtaining acoustic features from the utterance. Further actions include providing the acoustic features from the utterance to multiple speech locale-specific hotword classifiers. Each speech locale-specific hotword classifier (i) may be associated with a respective speech locale, and (ii) may be configured to classify audio features as corresponding to, or as not corresponding to, a respective predefined term. Additional actions may include selecting a speech locale for use in transcribing the utterance based on one or more results from the multiple speech locale-specific hotword classifiers in response to providing the acoustic features from the utterance to the multiple speech locale-specific hotword classifiers. Further actions may include selecting parameters for automated speech recognition based on the selected speech locale.
