1. Source characteristics of voiceless dorsal fricatives

    This paper provides evidence that dorsal fricatives in Arabic, Persian, and Spanish are more properly characterized as voiceless trills, with characteristics of trill vibration frequency and stability determined from oral airflow data, and spectral characteristics determined from acoustic recordings.
