About

The most realistic and versatile AI speech software, ever. Eleven brings the most compelling, rich and lifelike voices to creators and publishers seeking the ultimate tools for storytelling. Generate top-quality spoken audio in any voice and style with the most advanced and multipurpose AI speech tool out there. Our deep learning model renders human intonation and inflections with unprecedented fidelity and adjusts delivery based on context. Our AI model is built to grasp the logic and emotions behind words. And rather than generate sentences one-by-one, it’s always mindful of how each utterance ties to preceding and succeeding text. This zoomed-out perspective allows it to intonate longer fragments convincingly and with purpose. And finally you can do this with any voice you want.

About

Inworld TTS is a state-of-the-art text-to-speech platform designed to deliver ultra-realistic, context-aware speech synthesis and precise voice-cloning capabilities at a radically accessible price. The flagship model, TTS-1, is optimized for real-time applications and supports low-latency streaming (first audio chunk in ≈200 ms) as well as multiple languages (including English, Spanish, French, Korean, Chinese, and more). Developers can use instant zero-shot voice cloning (5-15 seconds of audio) or professional fine-tuned cloning, add voice-tags for emotion, style, and non-verbal sounds, and switch languages while preserving voice identity. The larger TTS-1-Max model (in preview) offers even more expressive speech and multilingual strength. The platform supports both API and portal access, streaming or batch mode, and is designed for everything from interactive voice agents and gaming characters to branded audio experiences.

Pros & Cons from Real Users

Pros

  • Aesthetic interface. The support team answer quickly when they are interested in selling you crap. A variety of languages and pronunciations just as on similar platforms.
  • Text to speech works seamlessly, consistently accurate and produces a high quality output superior to competitors. The real standout to me is voice cloning, must be experienced to appreciate the magic.
  • I’ve been using ElevanLabs for 6 months now. I’ve been impressed by the quality and range of voices available on TTSA, as well as how responsive the team is. The Discord was a life saver when I started producing audio using the platform and continues to be useful. Their voice cloning is also better than other services I’ve tried.
  • Super realistic voices, even whisper! It's fast (much faster than many others). It has tons of voices. 10.000 credits for free. Super easy download of MP3.

Cons

  • See below. When you realize what crap they sold you, you are strongly suggested to upgrade for an additional $200.
  • Wish it was more popular so there was a bigger community to leverage.
  • A bit on the expensive side once you’re producing a lot of audio, but worth the spend for the quality.
  • The voices change a little bit in tone each time you generate. This is great if you are looking for variations. But if you want 10 separate sentences in 1 tone, you can't generate them sentence by sentence, as they might not match in tone. (I hope you understand what I mean). Always need more voices ;-)
