Knovvu Text-to-Speech technology supports multiple languages, enabling businesses to communicate effectively with a diverse customer base. We are continually exploring new opportunities to expand our language support, so businesses can communicate effectively with customers around the world.

Supported Languages

We currently support the following languages through the endpoint:

Arabic, Azerbaijani, English, French, German, Indian, Japanese, Kurdish, Pashto, Persian, Russian, Spanish, Turkish, Ukrainian, Urdu.

Embracing Linguistic Diversity through Accent-Specific Voices

Text-to-speech (TTS) technology has advanced to the point where it can now offer voices that vary not only in language but also in accent, reflecting the rich diversity of speech patterns around the world.

For instance, in the realm of Arabic, TTS voices can differentiate between Saudi, Gulf, and Kuwaiti accents, each with its own unique pronunciation and intonation. Similarly, in English, there's a clear distinction between UK and US accents, catering to users' preferences for a more localized experience.

This capability enhances the naturalness and relatability of TTS systems, allowing for a more personalized and engaging interaction.
