The world's most emotive AI speech engine for enterprise. Experience synthesis that feels human.
Also available on mobile
Precise tools for the perfect performance.
Adjust intonation curves visually. Manipulate pitch contours to match the specific gravity or lightness of your script's intent.
Describe the delivery you want — warm and unhurried, brisk and factual, a hushed aside — and the engine reads it that way.
Turn a script into a finished video: generated scenes, your voiceover on top, subtitles and music mixed in one render.
Powered by neural synthesis
ProsodyAI runs two text-to-speech engines side by side — OpenAI & Google Gemini. Switch per project, on one account, with one quota.

Instant translation and dubbing across 40+ languages while preserving the original voice identity.
SOC-2 compliant infrastructure designed for high-volume, low-latency synthesis.
Pick the engine per project rather than per subscription. One account, one quota, and no second API key to manage — switch mid-project when a script wants a different read.
Describe the delivery in plain words and the engine reads it that way — warm and unhurried, brisk and factual, a hushed aside.
The same request shape for both engines, so changing your mind about the voice does not mean changing your code.

ProsodyAI runs the OpenAI and Google Gemini neural TTS engines, which produce speech virtually indistinguishable from a human recording.
Across both engines ProsodyAI covers 59 languages. OpenAI TTS supports 57 — including English, Turkish, French, German, Spanish, Portuguese, Italian, Dutch, Polish, Russian, Chinese, Japanese, Korean, Arabic, Hindi and more — while OpenAI TTS extends coverage to 57 languages and Google Gemini TTS adds regional voices such as Indonesian, Vietnamese, Thai, Ukrainian, Bengali and Tamil.
Two engines on a single account: OpenAI TTS (gpt-4o-mini-tts, 57 languages), and Google Gemini TTS (30 studio voices, low-latency generation). You pick the engine per project — no separate API keys, no separate subscriptions.
OpenAI TTS gives the widest language reach and the most polished, studio-grade read — best for multilingual narration. Google Gemini TTS is the fastest and most conversational, best for quick turnarounds. OpenAI and Gemini also accept plain-language style instructions, so you can simply tell the AI to sound warm, slow or excited.

Yes. All paid plans include full commercial usage rights for generated audio. You own the output and can use it in podcasts, videos, apps, games, advertisements, and any other commercial project without additional licensing fees.
Typical generation latency is under 3 seconds for short texts. Longer content is automatically chunked and processed in parallel. Our infrastructure keeps performance consistent under load.
Yes. A new account gets 1,000 premium characters to try, once, plus access to every built-in voice. No credit card required. Upgrade anytime to unlock the premium OpenAI and Gemini engines, higher quotas, more voice clones, priority processing, and commercial usage rights.
