Abstract: Techniques for speech-to-text hypothesis generation and hypothesis selection described. A text input representing at least part of a voice recording is received from a speech-to-text component. A first text alternative is generated using a finite state transducer based at least in part on the text input. A hypothesis from a hypothesis set is selected using a language model that includes probabilities for sequences of words, the hypothesis set including the text input and the first text alternative. A selected hypothesis text associated with the selected hypothesis is sent to a search engine.
