With over 7,000 languages spoken worldwide, many children grow up learning one or more. Some, however, face challenges in speech development and require support from specialists.
These presentations provide insights from global researchers, covering general language information, typical speech acquisition, and guidance on assessing and supporting children with speech sound disorders.
They're available in English and 40+ other languages, and growing.

You can discover how children learn to speak more than 45 home languages by watching over 70 presentations provided by international experts in each language. The experts explain where the language is spoken, the components of the language (vowels, consonants, tones), and the assessments and interventions available to support children learning to speak that language.
Once you have listened to the presentations in English, you can listen to the same information presented in the language being spoken about. For example, you can hear how children learn to speak Kurdish in an English presentation and then listen again in Kurdish, or you can listen to a presentation about Greek in English and in Greek. These presentations will appeal to speech-language pathologists, teachers, psychologists, and linguists, as well as others wanting to learn linguistic terminology for information about each language. They may also be of interest to parents, second language learners, and people who want to listen to professional language users speaking in the language.
You can also access the same presentations by language along with additional information including author details, summary abstracts, key words, reference, and the slides created by the presenters. Those presentations recorded in English as well as the language being spoken about, can be viewed side-by-side.
