Correlates of Turbulent Noise Production for Speech
Thomas J. Hixon, Fred D. Minifie, Charles A. Tait · Journal of Speech and Hearing Research · 1967
Intraoral air pressure, volume rate of airflow, and sound pressure level were measured during /∫/ and /s/ productions of two speakers. In addition numerical estimates of the loudness of the productions were made by each speaker and by a group of judges. The power laws governing the relations among the parameters of interest are discussed and the results are compared with available data on voice production.
