Likewise, for effective communication, much is dependent upon such things as gestures, emphases, and other modulations of voice.
The resonance, timber and modulation of his voice gave life to his expressive words that made me part of the game.
Similarly to the case of respiratory tremor, its main effect is amplitude modulation of the voice signal but it also causes frequency modulation with a lower modulation extent.
Reported results are consistent with previous knowledge in that respiratory tremor mainly causes amplitude modulation of the voice signal while laryngeal tremor causes both amplitude and frequency modulation.
Note that other shares of parameter controls between the GUI and chironomy are possible; for instance, modulation of breathiness, voice tension, or vocal tract length can be assigned to the stylus (see Table 2 for musical examples).
MS provides a visual representation of sound energy spread in acoustic and modulation axes [ 37, 38] supplying information about perturbations related to amplitude and frequency modulation of the voice signal.
Clearly, the era of teaching table manners and the decibel modulation of "outside voices" to children is long gone.
Over the summer, an Israeli firm called Beyond Verbal raised millions of dollars in funding; its vice president described how its software can "understand a speaker's transient mood and emotional decision-making characteristics in real time", by analysing the modulations of the voice.
Similarly, vibrato is a modulation of the acoustic voice signal too, but vocal tremor differs from it in that for vibrato, the span of typical modulation rates is narrower (between 4 and 7 Hz) [2] and the modulation is more cyclic [3].
