Read the licence before you pick a voice
Most free plans are for practice only. If the film is for a client, a brand or a monetised channel, you need a plan that includes a commercial licence. Check that first, before you get attached to a voice.

For Hindi and Telugu
Not every model speaks Telugu, even inside one company. In ElevenLabs, v4 and v3 handle both languages, while the older Multilingual v2 and Flash v2.5 handle Hindi only. Pick the model, not just the tool.
Always get a native speaker to listen before you publish. A voice can sound fluent and still stress the wrong syllable.
Free and open source
- Kokoro: small and quick, Apache-2.0 licence. Hindi, no Telugu.
- AI4Bharat Indic Parler-TTS: Apache-2.0. Hindi and Telugu.
- AI4Bharat IndicF5: MIT licence, 11 Indian languages. Clone a voice only with that person’s permission.
These cost nothing to use, but you run them yourself, which takes some technical setup.
Closed or changed
Older “best voice tools” lists still recommend these. Check before you sign up.
- Play.ht / PlayAI: closed at the end of 2025.
- Hume Octave: its voice service was scheduled to close in November 2026.
- Resemble AI: now sells deepfake detection, not voices.
- OpenAI’s older speech models (tts-1, gpt-4o-mini-tts): switched off on 6 January 2027.
Video tools that speak
Some video generators now make sound together with the picture: Google’s Veo 3.1 and its Gemini Omni successor, Kling, and Seedance 2.5. For a short line spoken on screen, that can replace a separate voice step. For narration, a dedicated voice tool still gives you more control.
Direct the voice like an actor
- Write for the ear. Short sentences, one idea in each.
- Punctuation is your pacing. A full stop is a breath.
- Generate line by line, so you can redo one line without losing the rest.
- Make three takes of every line and choose by listening, not by reading.
- Keep one voice and the same settings for a character through the whole film.
Then build the world around the voice: where to find sound effects.
Tools, prices and platform rules change often. Everything here was checked in November 2026; confirm on the tool’s own page before you rely on it.
