1. A method performed by a computer processor executing computer program instructions tangibly stored on a first computer-readable medium to perform a method comprising: (A) deriving, from a region of a document and a corresponding region of a spoken audio stream, a likelihood score representing a likelihood that the region of the document correctly represents content in the corresponding region of the spoken audio stream, and tangibly storing a representation of the likelihood score in a second computer-readable medium; (B) selecting a relevance score representing a measure of relevance of the region of the spoken audio stream, the measure of relevance representing a measure of importance that the region of the spoken audio stream be brought to the attention of a human proofreader, and tangibly storing a representation of the relevance score in a third computer-readable medium; and (C) deriving, by performing a calculation on the likelihood score and the relevance score, an emphasis factor for modifying emphasis placed on the region of the spoken audio stream when played back, and storing a representation of the emphasis factor in a fourth computer-readable medium.

The method of claim 1 , wherein the region of the document comprises a hypothesis generated by an automatic transcription system for the corresponding region of the spoken audio stream, and wherein (B) comprises: (B)(1) identifying a competing hypothesis generated by the automatic transcription system for the corresponding region of the spoken audio stream; (B)(2) selecting a prior relevance of the competing hypothesis; and (B)(3) selecting the measure of relevance based on the prior relevance of the competing hypothesis.
