The role of talker sex and physical dimensions in horizontal speech directivity.

ABSTRACT: Human speech directivity plays a role in speech perception, including for speech recognition in multi-talker environments. Individual variability in speech directivity patterns arises in part because of differences in physical attributes across talkers. Here, individual variability in horizontal speech directivity using anechoic, multi-channel, high-fidelity recordings of the Bamford-Kowal-Bench sentences produced by 15 female and 15 male talkers were examined. The frequency-dependent directivity index (DI) for each talker was calculated and the effects of frequency, sex, and body mass index (BMI) on directivity indices were tested. Minimum radiation toward 0° and maximum radiation toward 90° occurred at 700-850 Hz, resulting in an increase in spectral level at 90° compared to 0° for this
