Word-level correction of speech input

A system for correcting words in transcribed text, the system comprising:

• an automated speech recognizer operable to receive speech audio data and in response transcribe the speech audio data in a word lattice;
• and
• a computing device comprising:
• a microphone operable to receive speech audio and generate the speech audio data,
• a network interface operable to send the speech audio data to the automated speech recognizer and in response receive the word lattice from the automated speech recognizer,
• a display screen operable to present one or more transcribed words from the word lattice,
• a user interface operable to receive a user selection of at least one of the transcribed words, and
• one or more processors and a memory storing instructions that when executed by the processors cause the computing device to perform operations to:
• provide a transcription of an utterance for output in an output region of a display of a computing device;
• receive a user selection of a portion of the transcription of the utterance, the user-selected portion of the transcription of the utterance comprising one or more words;
• in response to receiving the user selection of the portion of the transcription of the utterance, present one or more controls at the display of the computing device that each correspond to (i) one or more alternate words for the user-selected portion of the transcription of the utterance or (ii) a remove command to remove the user-selected portion of the transcription of the utterance from the transcription of the utterance;
• receive a user selection of a particular control from among the one or more controls;
• and
• update the transcription of the utterance output in the output region of the display of the computing device based at least on the user selection of the particular control.

A computer program product, encoded on a non-transitory computer-readable medium, operable to cause one or more processors to perform operations for correcting words in transcribed text, the operations comprising:

• receiving speech audio data generated by a microphone of a computing device, wherein the speech audio data corresponds to an utterance received by the microphone;
• providing a transcription of the utterance for output in an output region of a display of the computing device, wherein the transcription of the utterance is obtained from an automated speech recognizer operable to transcribe the speech audio data corresponding to the utterance;
• receiving a user selection of a portion of the transcription of the utterance, the user-selected portion of the transcription of the utterance comprising one or more words;
• in response to receiving the user selection of the portion of the transcription of the utterance, presenting one or more controls at the display of the computing device that each correspond to (i) one or more alternate words for the user-selected portion of the transcription of the utterance or (ii) a remove command to remove the user-selected portion of the transcription of the utterance from the transcription of the utterance;
• receiving a user selection of a particular control from among the one or more controls;
• and
• updating the transcription of the utterance output in the output region of the display of the computing device based at least on the user selection of the particular control.
