Individual differences across caregivers in acoustic implementation of infant-directed and adult-directed speech: Modeling impacts on intelligibility in children with cochlear implants

Caregivers modify their speaking style from adult-directed speech (ADS) to infant-directed speech (IDS) when talking to infants. However, it is unclear how individual caregivers acoustically implement differences between ADS and IDS, and how these differences may affect experienced speech intelligibility by infants, particularly those with cochlear implants (CIs). Seven female talkers spoke fifteen utterances both in IDS and ADS. We analyzed...
