What is Indic-Speak?
Indic-Speak is a text-to-speech model from Bodhan AI, a company incubated at IIT Madras, built with AI4Bharat and released in September 2026 as one of four open Indic models. AI4Bharat's own Indic Parler-TTS page now recommends it in place of that older model. It is a speech language model of about 3.8 billion parameters on Llama 3.2 3B that predicts SNAC audio codes, which a fine-tuned Vocos decoder turns into 24 kHz audio.
It covers 22 Indian languages plus English: 13 at production quality (including Hindi, Bengali, Marathi, Telugu, Tamil, Urdu and Assamese) and 10 in preview, such as Bodo, Dogri, Santali and Sanskrit. It reads mixed-language text in native or Latin script. There is no voice cloning: every voice comes from a contracted voice artist who consented, and the hosted API lists 45 voices and 14 speaking styles.
Is Indic-Speak worth it?
Indic-Speak gives 22 Indian languages their own dedicated voices, twice the 11 of Maya2 Native, and every one of those voices belongs to someone who agreed to it. That matters in a market where cloning a teacher's or a film star's voice is the obvious abuse; Indic-Speak simply has no cloning, and its licence bans deepfakes, robocalls and voice phishing.
Breadth comes in tiers. Thirteen languages are marked production-ready and ten, including Bodo, Konkani, Kashmiri and Santali, are preview. Bodhan's only published scores are averages: a 26.49% word and 17.86% character error rate, a NORESQA quality score of 4.46 out of 5 and 96.47% voice consistency, with no comparison to other models. Maya Research's Maya2 Native, by contrast, has public arena results on Hindi.
The hosted API is the easy path. At ₹6 per 10,000 characters, a million characters cost ₹600, and the endpoint follows OpenAI's speech format with about 200 ms to first audio. The weights are 3B-class and need Transformers v5; no VRAM figure is published. AI4Bharat's older Indic Parler-TTS, at 0.9B under Apache 2.0, remains the lighter fallback, but its makers now point to Indic-Speak.
The catch: the licence is open but not Apache. You must credit Bodhan AI and AI4Bharat, keep derivatives under the same licence, and get Bodhan's written sign-off before offering it as an API to others, unless you are a non-profit, government or academic user. Products above 500 million monthly users or $250 million revenue need a separate deal. Style control is preview quality, it cannot laugh or sigh, and the model card's voice counts do not match the API's.
Our take: for an ed-tech or government service reading lessons and notices in many Indian languages, Indic-Speak is the default to test first; a consumer app that needs a custom brand voice will have to look elsewhere.
Where it earns its place
An ed-tech company producing school lessons in Hindi, Tamil and Odia
Turn written lessons into audio for students who read slowly
Send lesson text to the hosted API with a voice per language; at ₹6 per 10,000 characters, 5 million characters a month costs ₹3,000. Every voice is a consenting artist, so there is no rights question.
A state government department running a citizen helpline
Read scheme notices in Marathi and English, including mixed sentences
Self-host the weights on government servers; government users are exempt from the API sign-off rule. Mixed Marathi-English text in Devanagari or Latin script is read without pre-processing.
A news publisher in Assam
Offer an audio version of every article in Assamese and Bodo
Assamese is production-quality and Bodo is preview, so budget a listener to check Bodo output. Credit 'Built with Indic-Speak from Bodhan AI / AI4Bharat' as the licence requires.
Before you commit
- Setup
- Accept the licence on Hugging Face, install Transformers v5 and load the model; or create an API key at console.bodhan.ai and POST to /v1/audio/speech. New accounts get ₹10 of credit, no card needed.
- Integrations
- OpenAI-compatible speech endpoint at api.bodhan.ai/v1; Hugging Face Transformers for self-hosting; community ONNX and MLX conversions exist.
- Data and privacy
- Self-hosting keeps text local. Voices come only from consenting contracted artists; the licence bans cloning real people without consent, robocalls, voice phishing and disinformation, and asks you to disclose synthetic speech. The API page does not state data retention.
- Cost at scale
- API: ₹6 per 10,000 characters, prepaid in top-ups of up to ₹5,000, no subscription. Self-hosting is free below 500 million monthly users or $250 million revenue.
- Limits
- Preview-quality style control; no laughter, sighs or breaths; may mispronounce unusual words; per-key rate and concurrency limits on the API; no published VRAM figure.
