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. This tool could also be manually activated (206) by the user. The type of recognition problem is identified (216) by the user or automatically by the system, and the system provides (218) possible solution steps for enabling the user to adjust (219) system parameters or modify user behavior in order to alleviate the recognition problem. The system also provides the user the ability to test (222) the transcription process in order to determine whether the solution has improved the recognition accuracy.
