| Popis: | To use an automated speech-processing technology to identify patterns in sound environments and language output for deaf or hard-of-hearing infants and toddlers.Observational study based on a convenience sample.Home observation conducted by tertiary children's hospital.The system analyzed 115 naturalistic recordings of 28 children3.5 years old. Hearing ability was stratified into groups by access to sound. Outcomes were compared across hearing groups, and multivariable linear regression was used to test associations.There was a significant difference in age-adjusted child vocalizations (P = .042), conversational turns (P = .022), and language development scores (P = .05) between hearing groups but no significant difference in adult words (P = .11). Conversational turns were positively associated with each language development measure, while adult words were not. For each hour of electronic media, there were significant reductions in child vocalizations (β = -0.47; 95% CI, -0.71 to -0.19), conversational turns (β = -0.45; 95% CI, -0.65 to -0.22), and language development (β = -0.37; 95% CI, -0.61 to -0.15).Conversational turn scores differ among hearing groups and are positively associated with language development outcomes. Electronic media is associated with reduced discernible adult speech, child vocalizations, conversational turns, and language development scores. This effect was larger in children who are deaf or hard of hearing as compared with other reports in typically hearing populations. These findings underscore the need to optimize early language environments and limit electronic noise exposure in children who are deaf or hard of hearing. |
