Abstract
Automatic Speech Recognition has been widely employed in the last years. However, when a perfect transcription of the input is required, it is still necessary to rely on a human operator that supervises and corrects the mistakes that recognition systems usually make. Although the use of automatic systems can speed up the transcription process significantly, the intervention of these human supervisors can slow down this job considerably. Owing to this fact, the application of the Interactive Pattern Recognition approach to this task turns out to be a good opportunity to improve the cooperation between the computer and the human when an error-free transcribed document is needed.
In this chapter, an interactive multimodal approach for efficient transcriptions of speech signal is presented. This approach, rather than full automation, aims at assisting the expert in the proper transcription process. In this sense, an interactive scenario is proposed and it is based on a cooperative process between an automatic recognition system and a human transcriber to generate the final transcription of the speech signal. It will be shown how user’s feedback directly allows one to improve the system accuracy, while multimodality increases system ergonomics and user acceptability.
