Perceptual significance of the CID W-22 carrier phrase

The 2-part study provides evidence that the carrier phrase "You will say..." contains perceptual cues which can be used by the listener to help identify place of initial consonant articulation for many test words, and when these cues are removed, the test words in isolation constitute a mre difficult word discrimination test. In the first experiment, test words beginning with voiceless stop consonants were truncated from their carrier phrases, and the phrases alone were presented to 10 normally hearing listeners. Results demonstrated above chance performance by listeners for identification of place of initial consonant articulation for the deleted test words solely on the basis of carrier phrase cues. In the second experiment, acoustically identical W-22 words with and without carrier phrases were presented to 10 normally hearing listeners at a O dB signal-to-noise ratio. A significant difference was observed in word discrimination scores for the 2 lists that can be attributed to deletion of carrier phrase cues.
