Commercial use

YouTube
Yes, AI voices are allowed. What YouTube limits is mass-produced, repetitive content: videos made from a template with little original work. Its July 2025 update renamed that rule from “repetitious” to “inauthentic” content (YouTube’s monetisation policies).
Write your own script, add your own research or editing, and keep one consistent voice for the channel. Where a realistic AI voice could mislead viewers, use YouTube’s altered or synthetic content label. The monetisation decision is always YouTube’s.
The production problem
Commercial Hindi voice-over for social media or OTT runs about ₹25,000 to ₹80,000 for 3 to 6 months of use, per voice and per language (non-union rates, CapCut guide, November 2025). Across hundreds of episodes and several languages, that adds up fast.
Keeps the performance, but every language needs its own artists, sessions and fees, and voice artists for Bhojpuri or Marwari are hard to book at volume.
Many text-to-speech tools stop at Hindi and English, or read a dialect like Bhojpuri as Hindi with an accent. Your non-metro audience hears the difference.
Pāṇini was built for exactly this: one model, 250+ languages including deep regional dialects, at a quality that holds on a mobile speaker.
Use cases
One piece of writing becomes a Bhojpuri episode, a Marwari episode and a Telugu episode from a single API call.
Clone your narrator once. Every subsequent episode sounds like the same person, in any language, brand voice without re-recording.
Bhojpuri, Marwari, Haryanvi, Chhattisgarhi and more, written in the dialect and read as the dialect, with platform voices recorded by speakers of several of them.
Connect Pāṇini to your CMS. New written content triggers audio generation across every language you support, with no human in the loop.
Voice cloning
Send a ten-second sample. Pāṇini clones the voice and carries the original speaker's accent and pronunciation into every language you produce in.
No studio session, no extended recording.
The voice does not flatten to a generic pronunciation.
No per-language re-cloning required, ever.
AI voice for dubbing
For AI dubbing in Hindi and other Indian languages, Sonex gives you the voice track: your translated script read by Pāṇini, or by a voice cloned from the original speaker with their consent. You sync it to the video in your own editor.
What Sonex does not do: take a video, translate it automatically or lip-sync the result. If you need that, use a video tool for those steps and Sonex for the voice.
You or your translator write the script in the target language, line by line, with the timing of each line from the original. Have a native speaker check it.
Pāṇini reads the translated script in a platform voice, or in a voice cloned from the original speaker with their consent, so the dub sounds like the same person in Hindi, Tamil or any of 250+ languages.
Drop the audio into Premiere Pro, DaVinci Resolve, CapCut or any editor and line each clip up with its shot. Generate scene by scene so you can redo one line without touching the rest.

FAQ
Pāṇini is trained on telephony-grade audio at 8 kHz, not studio recordings. Quality holds on a mobile speaker in a noisy environment. This is a deliberate training choice, not an afterthought.
The cloned voice carries the original speaker's accent and pronunciation characteristics into every language, including regional dialects. The goal is a Bhojpuri episode that sounds like the original narrator, not a generic AI reading Bhojpuri text.
Yes. Pāṇini is a REST API. If your CMS can make an HTTP request, it can trigger audio generation. For platforms with custom pipeline requirements, our team can work through the integration directly.
Self-serve is pay-as-you-go via the dashboard. For platforms producing at scale, a direct commercial arrangement with volume pricing and committed terms is the better structure.
Audio starts streaming in under 200 ms from the API call. For long-form content the audio streams as it generates, so the first seconds of a ten-minute episode are available almost immediately.
Sonex supplies the voice track, not the finished video. You bring the translated script, Pāṇini generates the dubbed audio in a platform voice or a consented clone, and you sync it to the picture in your own editor. There is no upload-a-video workflow, no automatic translation of a video and no lip sync.
Yes, with their consent. Clone the speaker from a 10-second sample and use that voice for the translated script. One voice can speak across languages, and a cloned voice carries across languages too. The speaker's accent carries over into the new language.
Translate for length as well as meaning, generate one clip per line or scene, and speed up a clip that runs long, in your video editor or with the API's speed parameter. A translation that is much longer than the original will not fit however it is read, so shorten the line first.
Yes. Audio you generate, on the free tier or with paid credits, can be used on monetised YouTube channels, Shorts, Reels and in ads, with no attribution. YouTube limits mass-produced, repetitive videos, not AI voices, so write your own script and keep your edits original. The monetisation decision is YouTube's.
The audio you generate is yours to use, including commercially, with no attribution and no royalties to Sonex Labs. You are responsible for the script itself: if you read someone else's text, you need their permission.
