7. A method, comprising: by a computing device: obtaining speech recognition input that includes an occurrence of a first word, wherein the first word shares a pronunciation with a second word that is spelled differently than the first word; process the speech recognition input to identify probabilities for at least two different alternative language outputs, the probabilities including: a first probability of a first speech recognition output obtained by replacing the occurrence of the first word in the speech recognition input with the second word, and a second probability of a second speech recognition output obtained by leaving the occurrence of the first word in the speech recognition input; and when the first probability exceeds the second probability, replacing the occurrence of the first word in the speech recognition input to obtain the first speech recognition output having the second word, and wherein the probabilities are identified based on a third word that appears in sequence with the occurrence of the first word in the speech recognition input.

The method of claim 7 , wherein the speech recognition input comprises speech recognition training data.
