The air-flow fluctuations of the longitudinal velocity were measured by means of hot-wire anemometry downstream of the synthetic three-layer, self-oscillating, life-size vocal fold model. The mean airflow rate and the mean subglottic pressure were kept within physiologically relevant values for a normal human voice production. Resulted magnitudes of the turbulent fluctuation velocity component varied in the range 0.25 – 2.1 m/s and are comparable with those found in literature.
