The glottal waveform can be estimated indirectly through inverse modeling of microphone recordings

Evidence

The phonatory function, or the vibration of the vocal folds, is difficult to see due to their position, but, for example, with high-speed digital imaging it is possible to obtain a relatively accurate observation of how they vibrate, as shown in Figure 5.3. Other means of study are, for example, to use a contact microphone attached externally to the larynx or an electroglottograph to measure the external electrical conductivity changes in the skin close to the larynx caused by the opening and closing of the vocal folds (Colton and Conture, 1990). A further possibility is to analyse the speech waveform, as registered by a high-quality microphone, and to use inverse modelling techniques to derive an estimate of the the glottal waveform (Alku, 2011). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 561
