Abstract: Disclosed are apparatus and methods for processing spoken speech. Input speech can be received at a computing system. During a first pass of speech recognition, a plurality of language model outputs can be determined by: providing the input speech to each of a plurality of language models and responsively receiving a language model output from each language model. A language model of the plurality of language models can be selected using a classifier operating on the plurality of language model outputs. During a second pass of speech recognition, a revised language model output can be determined by: providing the input speech and the language model output from the selected language model to the selected language model and responsively receiving the revised language model output from the selected language model. The computing system can generate a result based on the revised language model output.
