摘要
A method and apparatus for indicating emotional stress in speech by detecting the presence of vibratto or rapid modulation of the phonation constituent within the speech signal envelope. The modulation is emphasized by rectification, smoothing, and time and amplitude discrimination of the speech wave form and is compared to a selected voltage level to produce a series of uniform pulses, the number of which is indicative of the magnitude of vibratto content.
