Multimodal Name Recognition in Live TV Subtitling
Original language description
In this paper, we present a method of combining a visual text reader with a system of automatic speech recognition to suppress errors when encountering out-of-vocabulary words – specifically names. The visual text reader outputs detected words that are mapped into a large list of names via the Levenshtein distance. The detected names are inserted into the class-based language model on the fly which improves recognition results. To demonstrate the effect on the real speech recognition task we use data from sports TV broadcasting where a lot of names are present in both the audio and video streams. We superseded manual vocabulary editing in live TV subtitling through re-speaking by an automated online process. Further, we show that automatically adding the names to the recognition vocabulary online and with forgetting lowers the WER relatively by 39 % in comparison with the case when names of all sportsmen are added to the vocabulary beforehand and by 15 % when only the relevant names are added beforehand.
