The aim of thisstudy is to determine the acoustic features of voice and speech of children with autism spectrum disorders(ASD) as a possible additional diagnostic criterion. The multiplicity of symptomatology, different age ofits manifestation, and the presence of a leading symptom complex individually for each child make itdifficult to diagnose ASD. To determine the specificity of speech features of ASD, we analyzed thespeech of children with developmental disabilities in which speech disorders accompany the disease -Down syndrome (DS), intellectual disabilities (ID), mixed specific developmental disorders (MDD).The features that reflect the main physiological processes occurring in the speech tract during voice andspeech production are selected for analysis. The speech of 300 children aged 4-16 years was analyzed.Speech files are selected from the speech database {"}AD_Child.Ru{"} (Lyakso et al., 2019). Acousticfeatures of voice and speech, which are specific for different developmental disorders, were determined.The speech of ASD children is characterized by: high pitch values (high voice); pitch variability; highvalues for the third formant (emotional) and its intensity causing {"}atypical{"} spectrogram of the speechsignal; high values of vowel articulation index (VAI). The speech of children with DS is characterized bythe maximal duration of vowels in words; low pitch values (low voice); a wide range of values of the VAIdepending on the difficulty of speech material; low values of the third formant; unformed most ofconsonant phonemes.
