摘要： In one example, a method includes outputting, at a presence-sensitive display operatively coupled to a computing device, a graphical keyboard comprising a plurality of keys and receiving an indication of a gesture to select a group of keys of the plurality of keys. The method may further include determining, in response to the indication, a candidate word based at least in part on the group of keys. The method may further include determining a group of alignment points traversed by the gesture and respective cost values for each of at least two keys of the plurality of keys. The method may further include comparing the respective cost values for at least each of at least two keys of the plurality of keys to determine a combination of keys having a combined cost value and outputting the candidate word that is based on the respective cost values.

摘要： A method may include receiving a context comprising data that is indicative of one or more characters input by a user at the first computing device, sending information comprising at least a portion of the context and determining a first predicted word based at least in part on the context. The determining may be based at least in part on a local language model. The method may include receiving a second predicted word from a second computing device within a time period. The second predicted word may be determined based at least in part on the context and a remote language model, and the local language and the remote language model may be different. The method may include identifying one of the first predicted word and the second predicted word as a final predicted word, and outputting the final predicted word at a display.

摘要： Training data from a plurality of utterance-to-text-string mappings of an automatic speech recognition (ASR) system may be selected. Parameters of the ASR system that characterize the utterances and their respective mappings may be determined through application of a first acoustic model and a language model. A second acoustic model and the language model may be applied to the selected training data utterances to determine a second set of utterance-to-text-string mappings. The first set of utterance-to-text-string mappings may be compared to the second set of utterance-to-text-string mappings, and the parameters of the ASR system may be updated based on the comparison.
