Sarvam AI Text to Speech review
A usage-priced TTS API for Indian languages, code-switching, and voice agents.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sarvam AI Text to Speech is a browser-based and API text-to-speech service built around Bulbul V3 voices. It targets developers, enterprises, content teams, education providers, voice-agent builders, IVR systems, and accessibility projects that need speech in Indian languages. The service supports 11 languages, 35+ voices, consent-based voice cloning, Hindi-English and other code-switching, and commercial use. Its web and API access make it suitable for both direct generation and integration into applications.
Pricing is usage-based rather than monthly. The Pay as you go plan costs INR 3 per 1,000 characters and includes universal credits across supported APIs, credits that never expire, and no monthly commitment. Sarvam also provides free signup credits, while the Enterprise plan adds higher rate limits, custom concurrency and throughput, volume discounts on credits, dedicated support, and SLAs. This structure fits teams that want to align spend with generated volume, while organizations with sustained traffic or operational requirements can move to enterprise terms.
The strongest technical fit is for applications that need regional language coverage and live audio delivery. Developers get REST and real-time streaming APIs, pace, pitch, loudness, and tone controls, requests up to 2,500 characters through REST, and output formats including MP3, WAV, AAC, Opus, FLAC, linear16, mulaw, and alaw. Integrations include LiveKit, Pipecat, Vapi, Twilio, Exotel, LangChain, Vercel AI SDK, and n8n. Sarvam is a strong choice for Indian-language voice experiences and code-switching; teams seeking a simple monthly subscription or longer single-request limits should consider alternatives.
