Repair is a very common phenomenon in spoken languages. Speakers usually repeat, add, replace, or even abandon some constructions in utterances for some mental reasons. A repair is composed of a repaired segment and a repairing segment which immediately follows the repaired segment. A repaired segment denotes the portion that the speaker utters need to be removed in order to correctly understand the speaker's meaning. Because the repairs introduce much noise in language processing, we cannot defer the task of repair processing to the latter stages. This paper employs acoustic and prosodic cues to correct Chinese speech repairs. The experiments show that these cues achieve a satisfactory result.
