Abstract
A transcription system (100) includes a computer (102), a monitor (104), and a microphone (110). Via the microphone, a user of the system provides input speech that is received and transcribed (204) by the system. The system monitors (205) the accuracy of the transcribed speech during transcription. The system also determines (210) whether the accuracy of the transcribed speech is sufficient and, if not, automatically activates (214) a speech recognition improvement tool and alerts (212) the user that the tool has been activated.
Claims11
A method for transcribing speech performed by a transcription system, the method comprising the steps of:
- transcribing a received input speech into transcribed speech that includes a sequential listing of words in text format;
- monitoring an accuracy of the transcribed speech to determine whether the accuracy of the transcribed speech is sufficient;
- automatically activating an interactive speech recognition improvement tool during a dictation session upon determining that the accuracy of the transcribed speech is not sufficient;
- and
- during the dictation session, improving the accuracy of the transcribing step for subsequent transcriptions using the speech recognition improvement tool.
A transcription apparatus for transcribing input speech into text format, the apparatus comprising:
- a computer that transcribes a received input speech into transcribed speech and monitors an accuracy of the transcribed speech to determine whether the accuracy of the transcribed speech is sufficient, and that automatically activates an interactive speech recognition improvement tool during a dictation session when the accuracy is not sufficient, and which, during the dictation session, improves the accuracy of the transcribing step for subsequent transcriptions using the interactive speech recognition improvement tool;
- a display monitor, coupled to the computer, that displays the transcribed speech;
- and
- a microphone, coupled to the computer, that receives the input speech.
A machine-readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:
- transcribing a received input speech into transcribed speech that includes a sequential listing of words in text format;
- monitoring an accuracy of the transcribed speech to determine whether the accuracy of the transcribed speech is sufficient;
- automatically activating an interactive speech recognition improvement tool during a dictation session upon a determination that the accuracy of the transcribed speech is not sufficient;
- and
- during the dictation session, improving the accuracy of the transcribing step for subsequent transcriptions using the speech recognition improvement tool.
