Service used in the Smartix electronic queue system is a simple and powerful API that allows to receive mp3 voice messages generated on the basis of a third-party voice platform.

Voice messages are transferred in real time or made in the form of pre-created cache of sound files. The cache is built on the basis of its own algorithms and on the internal database of the service.

Modern voice services at a relatively high level solve the issue of imitation of pronunciation close to natural — the problems of recreating the tone of the voice, smoothness of sound and intonation have been eliminated. The solution created by our company uses all advantages of modern technologies for recognition and voicing from the world’s largest developers.
