This study compared the speech and prosody-voice profiles for 30 male speakers with either high-functioning autism (HFA) or Asperger syndrome (AS), and 53 typically developing male speakers. Both HFA and AS groups had more residual articulation distortion errors and utterances coded as inappropriate for phrasing, stress, and resonance. AS speakers…

This study reviewed the exceptional educational needs histories of 36 children who had received preschool speech services at a phonology clinic. Findings indicated that 75-80 percent of children continued to have speech/language and other special education needs as they neared middle school and beyond. (Author/DB)

This study provides a clinical profile of 178 children (ages 3-6) with developmental phonological disorders, based on prior reports and new data on 64 children. Data discussed include gender, age, and severity; speech profiles; prosody-voice profiles; causal-correlates profiles; and a prevalence profile. (Author/JDD)

Ten preschool children with developmental phonological disorders were followed for seven years. Analyses characterize the sequence, rates, and error patterns of long-term speech-sound normalization in relation to developmental perspectives. Findings support the hypothesis of a critical period for speech-sound development, with long-term…

A conceptual framework for short-term and long-term speech-sound normalization research is presented, and 1-year normalization outcomes for the 54 children described in EC 609 708 are reported. Although certain individual speech variables were significantly associated with normalization, there were no speech, prosody-voice, or risk-factor…
