Free Text to Speech Online - AI Voice Generator

Pick an Engine, choose a Voice from the library, then press Play to hear the whole script or Download to save it as one MP3 or WAV. Long scripts are generated part by part and joined into a single file.

AI podcast turns one script into a whole conversation. Write each line with a speaker name in front of it, like Host: or Guest:, and every speaker gets their own voice from the library plus their own pause length. Nothing is uploaded and there is no limit on how many speakers you use.

Captions that match the audio. After you generate, the SRT and VTT buttons give you a subtitle file timed to the real length of every sentence. Load it straight into CapCut, Premiere, DaVinci, YouTube or Facebook, and the words stay locked to the voice.

Share link packs the script, the voices, the speed and the pauses into the link itself. Send it to a friend or drop it in a video description, and anyone who opens it hears exactly what you built - with no account, no server and no cost to you.

Device voice (0 MB) uses the voices already installed on your own computer, so it starts instantly but sounds as good as your operating system allows. It cannot be exported to a file.
Kokoro Studio (88 MB once) is a real open-source AI voice model - 54 studio voices across English, Spanish, French, Hindi, Italian, Japanese, Portuguese and Chinese. It is the fastest of the AI engines and the best all-rounder.
Supertonic Natural (252 MB once) is the most lifelike of the three. It speaks English, Korean, Spanish, Portuguese and French - pick the spoken language to match your script. Be aware it is a diffusion model, so it is noticeably slower than Kokoro and wants WebGPU for usable speed. Best for final, high-stakes audio; use Kokoro for drafts and for podcasts.

Smart text rewrites what a speech model would otherwise misread: $1,299.99 becomes "one thousand two hundred ninety nine dollars", 2026 becomes "twenty twenty six", 3:30 becomes "three thirty", and markdown formatting is removed. Turn it off to hear your text exactly as typed.

Both AI engines run inside your own browser. Your text is never uploaded, there is no API key, no account and no usage limit, and once the model is cached it keeps working offline. 100% free.
