Models
Overtone provides a versatile text-to-speech solution, supporting over 15 languages to cater to a diverse user base. It is important to note that the quality of each model varies, which in turn affects the voice output. Overtone offers four quality variations: X-LOW, LOW, MEDIUM, and HIGH, allowing users to choose the one that best fits their needs.
The plugin includes a default English-only model, called LibriTTS, which boasts a selection of more than 900 distinct voices, readily available for use. As lower quality models are faster to process, they are particularly well-suited for mobile devices, where speed and efficiency are crucial.
