Children who are deaf or hard of hearing (DHH) often have persistent language delays despite early identification and interventions. The technology-assisted language intervention (TALI), which incorporates augmentative and alternative communication technology into a speech-language therapy model, was designed to support language learning. The study objective was to evaluate the impact of the TALI on spoken language outcomes in DHH children.

Children aged 3 to 12 years with mild to profound bilateral hearing loss were enrolled in a single-site randomized controlled trial. Children were randomly assigned to receive the TALI or treatment as usual (TAU) (with no change in current care) and were followed for 24 weeks.
*Primary outcomes included spoken language measures elicited from language samples.
*Secondary outcomes included standardized assessments. Intention-to-treat analysis were used.

Results:
--Analysis focused on 41 children randomly assigned to TALI (n = 21) or TAU (n = 20). Among all participants, mean age was 6.3 years (SD 2.5).

--Over 24 weeks, children in the TALI group, compared with those in the TAU group, had significantly greater increases in the length of phrases they used to express themselves (beta = .91 vs .15, respectively).

--Similar findings were seen with conversational turn-taking and number of different words spoken.

Conclusively, having visual resources for language concepts that are usually difficult for DHH children to learn, helped children to process and comprehend spoken language more fully. Such interventions can reduce chronic language delays with the goal of enhancing lifetime results and independence across settings.
