Infant-directed speech: Final syllable lengthening and rate of speech
Keywords:Speech communication, Video recording, Infant-directed speech (IDS)
AbstractThe present study compared infant-directed speech (IDS) and adult-directed speech (ADS) for two mothers of preverbal infants. Each mother participated in two recording sessions, one with her child, and one with an adult friend. The primary objective of the study was to determine the influence of exaggerated utterance-final syllable lengthening on the rate of IDS. A secondary objective was to compare the rate of speech read to infants with the rate of spontaneous IDS. The results showed an overall slower rate of speech in IDS to preverbal infants compared with ADS, replicating previous research. However, when the utterance-final syllable was excluded from the calculation of rate, the rate of speech in spontaneous IDS and ADS did not differ significantly. Speech was read to infants at a slower rate than spontaneous IDS. Implications for future research are suggested.
