A Dynamic Alignment Algorithm for Imperfect Speech and Transcript
This paper presents a novel alignment approach for imperfect speech and corresponding transcription.The algorithm gets started with a 3-stage sentence boundary detection in audio,followed by a dynamic programming based search,to fmd the optimal alignment and detect the mismatches at sentence level.Experiments show promising performance,compared to the traditional forced alignment approach.The proposed algorithm has already been applied in preparing multimedia content for an online English training platform.
