Hearing clear speech primes subsequent degraded-same-speech recognition
Evidence
A standard trial consisted of a first presentation (snippet a ) in which the speech was degraded using noise-vocoding as previously described. Therefore it was largely unintelligible. The second snippet (snippet b ) contained the same speech, but in its original clear form. The noise-vocoded version was then played again (snippet c ). As such, this third condition was affected by priming because the original clear speech was played immediately before and because the speech was vocoded at the limit of intelligibility. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4371

- XREF: Priming of degraded-but-repeated speech connects to the broader literature on perceptual priming and top-down restoration of degraded signals.
- QUESTION: Does priming work because the exact words are matched, or would any matched-prosody clear speech prime the vocoded version?
