Synthetic speech prosody of digital assistents and their functions in the modern world
The article is devoted to the speech prosody analysis of digital assistants and their functions in the modern world. Peculiarities of their functioning in different spheres, in particular in educational, are considered and as well as tasks which they perform. Synthetic speech prosody is investigated on the example of voice assistants which speak in a female, male and genderless voice. Characteristics of melody (melodic scales and terminal tones), FF and intensity range, tempo and pause features, voice quality were taken into account. In the course of comparative study some identical and distinctive features of assistants’ speech were singled out. The results of the experiment demonstrate variability of prosodic parameters, used by digital assistants. Voice differentiation and different degrees of expressiveness depend on the sphere of application, users’ preferences and communication context.
