Synopsis
The Early Language in Victoria Study (ELVS) has been following the speech and language development of a large group of children (>1900) born in the surrounds of Melbourne, Victoria (Australia) since they were 8 months of age. ELVS continues to follow this same group of children as they transition from middle childhood to adolescence. There are a number of ELVS sub-studies investigating different areas of communication development including: stuttering, autism and bilingual language development.
