Combining re-speaking, partial agent transcription and ASR for improved accuracy / human guided ASR
View Patent ↗A speech transcription system is described for producing a representative transcription text from one or more different audio signals representing one or more different speakers participating in a speech session. A preliminary transcription module develops a preliminary transcription of the speech session using automatic speech recognition having a preliminary recognition accuracy performance. A speech selection module enables user selection of one or more portions of the preliminary transcription to receive higher accuracy transcription processing. A final transcription module is responsive to the user selection for developing a final transcription output for the speech session having a final recognition accuracy performance for the selected one or more portions which is higher than the preliminary recognition accuracy performance.
1. A speech transcription system for producing a representative transcription text from one or more audio signals representing one or more speakers participating in a speech session, the system comprising:
a preliminary transcription module for developing a preliminary transcription of the speech session using automatic speech recognition having a preliminary recognition accuracy performance;
a speech selection module for user selection of one or more portions of the preliminary transcription to receive higher accuracy transcription processing; and
a final transcription module responsive to the user selection for developing a final transcription output for the speech session having a final recognition accuracy performance for the selected one or more portions which is higher than the preliminary recognition accuracy performance.
2. The system according to claim 1 , wherein the preliminary transcription module develops the preliminary transcription automatically.
3. The system according to claim 1 , wherein the preliminary transcription module develops the preliminary transcription with human assistance.
4. The system according to claim 1 , wherein the speech selection module makes the user selection based on one more specified selection rules.
5. The system according to claim 1 , wherein the speech selection module makes the user selection by manual user selection.
6. The system according to claim 1 , wherein the final transcription module develops the final transcription output using manual transcription.
7. The system according to claim 1 , wherein the final transcription module develops the final transcription output using automatic speech recognition.
8. The system according to claim 7 , wherein the final transcription module uses transcription models adapted from information developed by the preliminary transcription module.
9. The system according to claim 7 , wherein the final transcription module uses transcription modules adapted from one or more different speakers.
10. The system according to claim 1 , wherein there are a plurality of different audio signals representing a plurality of different speakers participating in the speech session.
