Improving speech recognition transcriptions

A computer system for improving speech recognition transcriptions, the system comprising:

• one or more computer processors;
• one or more computer readable storage device;
• computer program instructions stored on the computer readable storage device, comprising instructions to:
• identify one or more high frequency terms based on the history of utterances;
• convert the identified one or more high frequency terms into one or more phonemes;
• generate a sounds similar list for the identified one or more high frequency terms, based at least in part, on the one or more phonemes;
• transcribe an utterance from a virtual assistant into a transcription including one or more words, wherein the transcription is based on a predictive deep neural network;
• calculate a transcription score for each of the one or more words included in the transcription;
• and
• responsive to the transcription score for a word from the transcription being below a threshold, compare one or more phonemes of the word having the transcription score below the threshold to the one or more phonemes of the high frequency terms on the sounds similar list to determine a sounds similar score and replacing the word included in the transcription having the transcription score below the threshold with a high frequency term on the sounds similar list if the sounds similar score is above a threshold.

A computer program product for improving speech recognition transcriptions, the computer program product comprising a computer readable storage media device and program instructions sorted on the computer readable storage media device, the program instructions including instructions to:

• identify one or more high frequency terms based on the history of utterances;
• convert the identified one or more high frequency terms into one or more phonemes;
• generate a sounds similar list for the identified one or more high frequency terms, based at least in part, on the one or more phonemes;
• transcribe an utterance from a virtual assistant into a transcription including one or more words, wherein the transcription is based on a predictive deep neural network;
• calculate a transcription score for each of the one or more words included in the transcription;
• and
• responsive to the transcription score for a word from the transcription being below a threshold, compare one or more phonemes of the word having the transcription score below the threshold to the one or more phonemes of the high frequency terms on the sounds similar list to determine a sounds similar score and replacing the word included in the transcription having the transcription score below the threshold with a high frequency term on the sounds similar list if the sounds similar score is above a threshold.
