What speech costs, Amazon Polly and Voice Infra, in their words
Detail	Amazon Polly	Voice Infra
Published price	Standard $4.00, Neural $16.00, Generative $30 and Long-Form $100.00 per 1 million characters aws.amazon.com	₹1.80 per 1,000 characters, on pay as you go and on Business (₹50,000/month commitment), before GST

What it costs

Polly lists ₹380 per million characters for Standard voices and ₹1,519 for Neural. Generative and Long-Form cost more, but neither has a Hindi voice. The free tier is long: 5 million Standard characters a month, and 1 million Neural a month for your first year.

Mira TTS is ₹1.80 per 1,000 characters, so 10 lakh cost ₹1,800. That’s more than Polly. You pay from a prepaid rupee wallet. A request that fails costs nothing, and every response says what it cost, in paise.

Why switch

Why people switch to Voice Infra.

On pay as you go and on Business, paid from one rupee wallet. No plan to pick first.

Eight Indian languages, live.

Speech recognition and the model run on our own GPUs in India.

The listening and the thinking: Mira STT and Gemma 4 26B. Mira TTS speaks.

Ready for the phone line.

Ask for 8 kHz μ-law or A-law and send it straight down the line. Or take 48 kHz PCM for everything else.

Phone agents, on the same key.

Two Hindi voices, or four

Here is how Polly and Voice Infra differ.

If you use Polly for Hindi, your voice is Aditi or Kajal. They're solid bilingual voices, and Polly serves Kajal from Mumbai. Mira TTS gives you four newer voices, made for phone calls where English words come up all the time, in Hindi, Gujarati, Marathi, Bengali, Tamil, Telugu, Kannada and Malayalam, at ₹1.80 per 1,000 characters from a rupee wallet.

Polly is AWS’s speech service, with four voice engines on one price list. Hindi has two voices on it. Aditi uses the older Standard engine and Kajal the Neural one. AWS says both are fully bilingual in Hindi and Indian English, switch inside a sentence, and read Hindi in Devanagari or Latin script. Neural voices run in Mumbai, and Speech Marks give you word timings for captions.

Mira TTS has four voices: ashu, neha, shruti and sameer. We made them for phone calls in India, where “आपका order” and “delivery” share a sentence all day long. They speak Hindi, Gujarati, Marathi, Bengali, Tamil, Telugu, Kannada and Malayalam.

Which to pick

Which is right for you?

Sometimes it's them. We'll say so.

Choose Polly if…

You run on AWS and want the voice in the same account, served from Mumbai.
You need Speech Marks, the word timings Polly returns for captions and lip sync.
Price comes first. Polly's Hindi voices cost less per character than ours, and the free tier is long.
Your text is Romanised Hindi. AWS documents it for both its Hindi voices.

Choose Voice Infra if…

You want more than two Hindi voices, made for phone calls.
You need Gujarati, Tamil or Telugu too. Polly lists Hindi and Indian English only.
Your code speaks OpenAI's speech API, or you build on Pipecat.
You'll want call transcripts or a full phone agent on the same key later.

Moving

Moving your code across is easy.

Your code stays. Three values change.

Step 1
Get an API key.
Look around with no sign-up. When you are ready, create a key in Developers.
Step 2
Change three values.
The base URL, the model and the voice. The rest of your OpenAI code stays as it is.
Step 3
Pick a voice.
Four voices, each speaking Hindi, Gujarati, Marathi, Bengali, Tamil, Telugu, Kannada and Malayalam.

Get an API key

What changes when you switch

You swap a SynthesizeSpeech call for OpenAI’s speech API: POST /v1/audio/speech with model: "mira-tts", a voice, a format, and up to 2,000 characters of text. Polly’s mulaw and alaw become our ulaw_8000 and alaw_8000. Its pcm maps to ours, which is 48 kHz unless you set sample_rate. We have nothing like Speech Marks, so keep Polly for anything that needs them.

On a live call, our WebSocket endpoint keeps one connection open, takes text as your model writes it, and stops a reply when the caller talks over it. On Pipecat, pipecat-mirai handles that for you.

Hear them side by side

Write a script from your own calls, with names, amounts, dates and an OTP. Add lines that switch language halfway, since both of us say we handle that. Render it with Kajal and with two of our voices. Play the clips blind to people who speak Hindi every day, then play the winner over a phone line. The Hindi TTS comparison lists the other options and their prices.

If your Hindi voice reads out a phone menu today, look at our agents too. They listen and answer, and cost ₹1.50 a minute all-in on the volume plan.

Questions

Here is what people ask before switching from Polly.

What do 10 lakh characters cost on each?

On Polly, ₹1,519 ($16) with Kajal and ₹380 ($4) with Aditi, before the free tier. On Mira TTS, ₹1,800. So Polly costs less per character; the reasons to switch are the voices and the call.

Can Mira TTS read Romanised Hindi?

We write Hindi in Devanagari, with English words in Latin script, and that's how we test our voices. If your text is Romanised Hindi, try a sample first. Polly documents it for Aditi and Kajal, and our docs don't.

Can I get phone-ready audio?

Yes. Ask for ulaw_8000 or alaw_8000 and pass each chunk to Twilio, Plivo or your SIP leg as it arrives. Exotel streams take pcm_8000.

Still deciding? Ask us.
