Evaluation of speech intelligibility with the coordinate response measure

This is the authors' abstract. We don't add key points for this paper.

The sentences in the coordinate response measure (CRM) corpus described in a recent letter to this journal [Bolia et al., J. Acoust. Soc. Am. 107, 1065–1066 (2000)] have been used to measure speech intelligibility as a function of signal-to-noise ratio with a speech-spectrum-shaped noise masker. The data from this experiment, along with those of an earlier experiment comparing intelligibility with the CRM and the well-known modified rhyme test (MRT), have also been used to estimate performance with the CRM as a function of the articulation index (AI) for a variety of different masking signals. The results provide a normative evaluation of the CRM for potential users of the CRM corpus, and can be used to compare the CRM with other measures of speech intelligibility.
