Effect of Gas Constants on Voicing Frequency

Zusammenfassung:It is well known that the composition of the exhaled gas has no large effect on voicing periodicity but, so far, the question of small effects has been left open. Mathematical models of vocal-cord action, though admittedly imperfect, nevertheless indicate, by virtue of the fact that the expressions contain gas constants, that some effects might be expected to occur. However, the results of experiments to detect such effects are too greatly influenced by talker variability when conversational speech is used as the test material. The present paper describes an experiment designed to reduce the effect of talker variability. The subject is presented with a complex tone through earphones. It is his task to match the frequency of the tone vocally, but after it has been removed and noise sufficient to mask his own performance substituted on the earphones. Under such conditions, the usual auditory feedback is lacking, and only proprioceptive feedback is available to position and tension the vocal cords. Preliminary results from measuring voicing frequency with various gases will be reported.
