Tool and method for enhanced human machine collaboration for rapid and accurate transcriptions

摘要

A system and methods for transcribing text from audio and video files including a set of transcription hosts and an automatic speech recognition system. ASR word-lattices are dynamically selected from either a text box or word-lattice graph wherein the most probable text sequences are presented to the transcriptionist. Secure transcriptions may be accomplished by segmenting a digital audio file into a set of audio slices for transcription by a plurality of transcriptionist. No one transcriptionist is aware of the final transcribed text, only small portions of transcribed text. Secure and high quality transcriptions may be accomplished by segmenting a digital audio file into a set of audio slices, sending them serially to a set of transcriptionists and updating the acoustic and language models at each step to improve the word-lattice accuracy.
