Official title: Promoting System-Wide Change for Bilingual Children with Speech Sound Disorder

Funded at University of Iowa · NIH-11318900 · Data updated 2026-11-12

This work will teach Spanish–English bilingual children with speech sound problems to produce harder speech sounds so their overall speech improves in both languages.

Who could benefit from this research

Could help

Spanish–English bilingual children (young childhood/early school age) who have diagnosed speech sound disorders and difficulty producing specific speech sounds.

Less likely to help

Children who are not bilingual, whose speech problems are caused by hearing loss or significant neurological conditions, or older teens/adults are unlikely to benefit from this specific program.

What this research studies

You and your child would be invited to a program that focuses on practicing more complex speech sounds, like consonant clusters, that can help other sounds get better too. The team will work with Spanish–English bilingual children, provide targeted practice sessions, and track changes in speech across both languages. Children will have regular sessions at the clinic or partner sites and their speech will be measured before and after the program. The aim is to find a faster, more efficient way to help bilingual kids gain clearer speech.

Why it matters

Potential benefit: If successful, this approach could speed up speech improvement for bilingual children and reduce how long they need therapy.

How similar studies have gone: Previous work with English-only children showed that teaching more complex sounds can produce broader speech gains, but testing this approach in Spanish–English bilingual children is relatively new.
