A system and method for providing a transcription service over a network. The transcription service includes a transcription server, a database, and several communication gateways. A transcription request is received by the system from anyone and includes an audio file, transcription instructions are derived by the system from a requestor profile, from preferences submitted with the audio file, or both. The request is then processed by the transcription server, the audio file is transmitted to at least one transcriber for transcription, transcribers receive the audio file, transcribe the file, and send the transcription back to the transcription server. The transcription server processes the file and sends the transcription to the entity that requested the transcription. Transcription accuracy is validated statistically by the system, thereby enabling reliable transcription from unknown transcription nodes. Profiles may be configured for both transcribers and transcription requestors. A rating and other performance metrics may be generated, monitored and maintained by the transcription system for a transcriber.
