Does Reading Clearly Produce the Same Acoustic-Phonetic Modifications as Spontaneous Speech in a Clear Speaking Style?

This paper describes an acoustic-phonetic comparison of casual and clear speech styles elicited in read and spontaneous speech. For the spontaneous speech, 20 pairs of English talkers were recorded doing a problem-solving picture task in good and degraded listening conditions. Each person also read sentences in casual and clear styles. The read clear speech was an exaggerated form of clear speech relative to the spontaneous clear speech: it had higher median F0 in both styles, a greater increase in F0 range and greater decrease in speaking rate between casual and clear styles, and trends towards greater vowel space expansion.
