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.

config = TTSConfig(model="zero-indic", voice="Varun")
await client.tts.synthesize("नमस्ते, आप कैसे हैं?", config=config)

python

# Tamil-native voice speaking English
config = TTSConfig(model="zero-indic", voice="Murugan")
await client.tts.synthesize("Good morning, how are you?", config=config)

Voice selection guide

Pick the voice whose native language matches the primary language of your content, it produces the most natural accent and prosody. Only pick a cross-lingual voice when you have a specific brand reason.

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="zero-indic", voice="Rajesh", language="hi")

python

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

python

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