Trusted by businesses worldwide
Native TTS for Hindi, Tamil, Telugu, Bengali, Marathi, Kannada, Malayalam, Gujarati, Odia, Punjabi, and Assamese. Each language has dedicated models trained on native speakers.
Sarvam's proprietary Bulbul text-to-speech engine is trained specifically on Indian language data, producing natural pronunciation, correct stress patterns, and authentic intonation.
Handles Hinglish and other mixed-language patterns naturally. When callers mix Hindi and English (or any two languages), the TTS seamlessly switches between languages mid-sentence.
Supports regional accent variations within languages. The Hindi voice sounds different for Delhi, Mumbai, and Lucknow contexts, matching the caller's regional expectations.
Optimized for Indian telephony infrastructure with streaming output and low first-byte latency, ensuring smooth conversations even on Indian mobile networks.
Cost-effective pricing designed for the Indian market. Significantly lower per-character rates compared to global TTS providers, making large-scale Indian voice AI affordable.

Edesy detects the caller's language from the conversation context and routes TTS requests to the appropriate Sarvam Bulbul language model.
The LLM response is preprocessed for Indian language TTS, handling transliteration, number formatting, and mixed-script text correctly.
Sarvam's Bulbul engine synthesizes speech with native pronunciation, correct intonation, and natural rhythm specific to the target Indian language.
The synthesized audio is streamed to the caller via the telephony provider, optimized for Indian mobile network conditions and audio codecs.
"Our customers in Tamil Nadu immediately noticed the difference. Sarvam's Tamil voice sounds like a real person from Chennai, not a robotic translation. Customer engagement doubled."
