Recent studies indicate that children with ASD have a significantly higher risk of co-occurring speech sound disorders than typically developing children. Early atypical speech development may be a critical yet overlooked bottleneck hindering their language improvement. Given the unique phonetic features of Mandarin, it is essential to investigate speech development in Mandarin-speaking children with ASD. This study aims to construct developmental trajectories and establish early identification and prognosis prediction models for this population.
