Voices & languages

46 speaker voices, one male and one female per language, spanning 23 Indic languages and English. The voice parameter controls vocal character; the input text controls the language spoken. They're independent.

Cross-lingual synthesis

Any voice can speak any language. A Tamil-native voice can read Hindi text (with a Tamil-inflected accent); an English-native voice can read Bengali. Useful for brand consistency across markets.

Language hint for preprocessing

The optional language field in TTSConfig hints the text preprocessor, it decides how to expand numbers, dates, and script-specific rules. It does not restrict what language the model speaks.

python

# Devanagari number expansion, Hindi date formats
config = TTSConfig(model="radiance-indic", voice="Rajesh", language="hi")

python

# English number expansion, English date formats
config = TTSConfig(model="radiance-indic", voice="Varun", language="en")

python

# Model auto-handles mixed scripts natively
config = TTSConfig(model="radiance-indic", voice="Varun")
