How long will it take to develop a new language?

A 1000-hour heterogeneous speech training dataset is required to develop a new language. Exact terms will be subject to the quality of this dataset and whether a model for this language already exists or not.

What is SSML?

SSML (Speech Synthesis Markup Language) is a markup language made for speech synthesis applications. It is used to apply tweaks and adjustments to synthetic voices, e.g., to make the voice higher on a specific part of speech.
