ProsodyAI uses a proprietary neural TTS engine that produces speech virtually indistinguishable from human recordings. With emotion control and prosody fine-tuning, the output captures natural intonation, breathing patterns, and subtle vocal nuances.
Across all three engines ProsodyAI covers 59 languages. The free Prosody engine supports 23 — 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.
Three engines on a single account: the Prosody engine (our own emotion-driven model with zero-shot voice cloning, free on every plan), 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.
Prosody is emotion-first: 8 emotion presets and voice cloning, best for storytelling and cloning your own voice. 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.
Upload a short audio sample (as little as 10 seconds) of the target voice. Our zero-shot cloning engine analyzes the vocal characteristics and creates a digital voice profile. You can then generate unlimited speech in that voice across all supported languages and emotions.
Absolutely. All audio files are encrypted at rest and in transit. Voice cloning data is isolated per workspace and never shared. We are GDPR and KVKK compliant, and you can delete your voice data at any time with full consent revocation support.
Rate limits depend on your plan. Free tier allows 10 requests per minute, while paid plans scale up to 200+ requests per minute. Enterprise customers get custom rate limits and dedicated infrastructure. All plans include priority queuing based on subscription tier.
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 GPU-accelerated infrastructure ensures consistent performance even under heavy load, with enterprise SLA guarantees available.
Yes! Our free tier includes 100,000 characters per month, one voice clone, and access to every built-in voice across 23 languages. 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.
