Global knowledge in 131 languages and dialects about children’s speech development, assessment, and intervention

assessment and intervention resources for supporting multilingual children's speech. The Multilingual Children's Speech website https://www.csu.edu.au/research/multilingual-speech/home has curated 1337 (mostly free) resources for supporting multilingual children's speech acquisition, assessment, and intervention in 131 of the world's languages and dialects (86 languages). Specifically, there are 658 speech acquisition studies in 55 languages, 423 speech assessment resources in 77 languages, and 178 speech intervention resources in 21 languages. This free website includes links to assessment tools, intervention manuals, journal articles, books, chapters, theses, and video recordings for 16 of the top 20 most spoken languages in the world and many minority languages, Indigenous languages (e.g. Māori, Samoan, Sesotho, Setswana, Warlpiri, isiXhosa, Zapotec, isiZulu) and languages and dialects impacted by colonisation and slavery (e.g. African American English, Fiji English, Jamaican Creole, Tok Pisin). Only 17.95% of the resources are about English, with 51.68% about 39 other Indo-European languages, and 30.37% about 46 languages belonging to 15 non-Indo-European language families. Previous analyses of curated knowledge about children's development in psychology and linguistics have found a WEIRD bias 'Western, Educated, Industrialized, Rich, and Democratic societies'; however, only 29.07% of the languages included on the Multilingual Children's Speech website are WEIRD. While only 1.23% of the 7000 world languages are represented on the website, these assessment and intervention resources will continue to grow due to ongoing work of multilingual communication specialists across the globe.
