Adult readers signal metric and phrasing structure through acoustic variation in a Spanish children’s book

Mara Breen, Sheyla Garcia, Genevieve Franck, Ahren Fitzroy

The current study investigated how adult speakers produce the children’s book El Gato Ensombrerado, a Spanish translation of Dr. Seuss’ The Cat in the Hat, which maintains the original book’s consistent metric and rhyme scheme. Using linear mixed-effects regression, we assessed how metric and rhyme structure – in addition to lexical, syntactic, and semantic features – account for duration, intensity, and pitch variation on each syllable. Similar to previous English findings, we show that adult Spanish speakers consistently signal hierarchical metric structure: higher metric strength is cued by increasing duration, decreasing intensity, and decreasing pitch. In addition, speakers signal rhymes with intensity and pitch, though this effect is unlike that previously observed for English. These results demonstrate similarity in the realization of metric structure across languages, and further demonstrate the consistent cues to linguistic structure that child listeners receive through hearing children’s books read aloud.
