Two Hindi text-to-speech APIs price in rupees: our Mira TTS at ₹1.80 per 1,000 characters, and Sarvam's Bulbul from ₹2.00 on pay as you go, less on its monthly plans. ElevenLabs, Google, Azure, Amazon Polly, OpenAI and Cartesia price in US dollars.

How do I test Hindi TTS on my own script?
A leaderboard averages other people’s sentences. Test yours:
- Take the twenty or thirty lines your app says most.
- Add names, rupee amounts, dates, phone numbers, an OTP, and English words like “order”, “refund” or “delivery”.
- Write Hindi in Devanagari with English in Latin script, and also in Roman script if that’s how your text arrives.
- Render every line in each shortlisted voice, labelled with model and voice.
- Play them, shuffled and unlabelled, to people who speak Hindi daily. Ask what sounded wrong, not only which they liked.
- Play the best two over a real phone call at 8 kHz, which hides some errors and exposes others.
For a live agent, also time the gap before the reply’s first audio. The Hindi TTS guide has starter sentences, and the OpenAI-compatible TTS guide gets you audio in a few lines.
Pricing a whole calling agent instead? Ours cost ₹1.50 a minute all-in on the volume plan, voice included.

Questions
These are the questions developers ask us most.
Which Hindi TTS API is cheapest?
It depends on your volume and your currency. In rupees, Mira TTS is ₹1.80 per 1,000 characters on pay as you go. Sarvam's Bulbul V4 Flash is ₹2.00 on pay as you go, and ₹1.70 on its Growth and Business plans, which carry a monthly payment. Google's and Amazon's free tiers cover the first million or more characters a month. Convert the dollar prices at your own rate.
Which Hindi TTS voice sounds best?
It depends on the script. Public leaderboards average other people's sentences, and we don't quote one for Mira TTS today. Test your shortlist on your own lines, played blind to native speakers.
Which Hindi TTS APIs handle Hinglish?
Each vendor describes it differently. Mira TTS voices switch into English. Sarvam's Bulbul V4 Flash has voices tagged enhi for English-Hindi code-mixing. Amazon Polly's Aditi and Kajal switch between Hindi and Indian English within a sentence. Cartesia says Sonic 3.6 has expanded support for Hindi written in Latin script. Test your own mixed sentences either way.
Is Mira TTS priced like the agents?
No. A whole phone agent on our volume plan is ₹1.50 a minute all-in, with our line and insights. Mira TTS on its own is ₹1.80 per 1,000 characters over HTTP, or ₹0.90 a connected minute on the WebSocket, before GST.
