Using acoustic and prosodic cues to correct Chinese speech repairs

Speech repairs introduce much noise in spoken language processing. Properly correcting speech repairs can help the speech recognizer to avoid the textual errors, and prevent the interpretation errors during the subsequent processing. Because the task of repair processing cannot defer to the latter (word segmentation, part-of-speech tagging and sentence parsing) stages, this paper employs acoustic and prosodic cues to correct Chinese repetition and addition repairs. The experimental results show that the precision rate of 93.87% (76.09%) and the recall rate of 90.65% (70%) can be achieved for correcting Chinese repetition (addition) repairs.
