Quality of speech synthesis

The quality of synthesized speech refers to how well it resembles a human voice and conveys emotion through intonation.

The Yandex speech synthesis technology doesn't piece together fragments of actual speech – it trains an acoustic model on a dictor's speech. To do this, we use a statistical approach with a recurrent neural network. This creates a somewhat artificial-sounding voice, but the resulting speech is smooth, with natural intonation.

The statistical approach also allows us to change the parameters of existing voices. This means that you can choose the intonation for vocalization of a text.
