متن کاملReal-time correction of closed-captions
Live closed-captions for deaf and hard of hearing audiences are currently produced by stenographers, or by voice writers using speech recognition. Both techniques can produce captions with errors. We are currently developing a correction module that allows a user to intercept the real-time caption stream and correct it before it is broadcast. We report results of preliminary experiments on corr...
متن کاملFull Utilization of Closed-captions in Broadcast News Recognition
Lightly supervised acoustic model training has been recognized as an effective way to improve acoustic model training for broadcast news recognition. In this paper, a new approach is introduced to both fully utilize the un-transcribed data by using closed captions as transcripts and to select more informative data for acoustic model training. We will show that this approach is superior to regul...
