Early detection and early management of children with Autism Spectrum Disorder (ASD) are crucial to their developmental outcomes. Vocalization refers to the noises that children create before they begin to talk. Studies have indicated that non-speech-like and speech-like vocalizations are the most prevalent cause of ASD children before the age of 2 possible identifying markers. Theoretical reasons for aberrant vocalization in children with ASD largely comprise motivation-oriented, neuromotor-oriented, sensory-oriented and social feedback-oriented to the theory. Future research may be explored to study the potential of aberrant vocalization as a unique early identification flag in children with ASD, boosting sobbing in children with ASD. Research on early screening, examining automatically trained classification models based on the best-predicted set of auditory characteristics, exploring the impact of intrinsic and social motivation on ASD The effect of children's speech-like vocalization and further research on the brain mechanism of ASD children's speech-like speech abnormalities. Thus, early detection and early action gives a more objective theoretical grounding.
