For human infants, producing recognizable speech is more than a cognitive process. It motor skill that requires infants to learn coordinate multiple muscles of varying functions across their body. This coordination directly linked ongoing fluctuations in heart rate; physiological process can scaffold behavior. We investigated whether rate coincide with vocal production and word formation 24-mo-old infants. Infants were most likely produce vocalization when reached peak (local maximum) or trough minimum). Vocalizations produced at the longer expected by chance. Functionally, vocalizations just before trough, while decelerating, be recognized as naive listeners. Thus, for developing infant, align timing productions are associated duration likelihood speech. Our results have broad immediate implications understanding normative language development, evolutionary basis production, potential early indicators communication disorders.

In the target article, authors give evidence of infants’ use gestures to support early communication in a speech-plus-gesture model spoken language acquisition. I propose extend this account include ‘vocal gestures’ – that is, vocal productions incorporate phonetic, prosodic or phonological features not typical language. These forms have been reported various case study accounts production, and are often highly iconic. another component multimodal communication, should be included our analyses speech development.

ABSTRACT Speech development occurs in highly variable environments; however, little is known about the effect of situational context on emerging infant vocalizations. At 4 time points (4, 6, 9, and 12 months), we longitudinally measured vocalizations 104 White infant‐caregiver dyads (41 girls) during three play contexts: book‐sharing, toy play, rattle‐shaking. The frequency differed between contexts only at months age. Meanwhile, caregivers systematically spoke more frequently book‐sharing than other from age onwards. Book‐sharing elicited conversational turns dyadic level 9 Our results show emergence vocal differentiation by infants role facilitating early turn‐taking.
