Finally—AI voices that actually sound humanElevenLabs offers a wide variety of high-quality voices that sound natural and human. The interface is easy to use, and it’s simple to test and fine-tune different tones. It also integrates smoothly into our existing workflows, making it easy to automate calls and adapt to different use cases. The voice cloning and multilingual support add even more flexibility. The real-time voices are impressive but still feel slightly off at times, especially in longer conversations. While there are many voices available, only a few sound truly natural, so finding the right one can take some time. Iterating through voices and settings can be a bit clunky, and the prompt-building suggestions aren’t always helpful—so there’s a lot of trial and error involved to get a reliable setup. It’s a powerful tool, but getting to a production-ready voice takes patience. Ignacio G.

Authentic Sounding Voices!Love ElevenLabs. For a while I have been looking for a solution to speed up my work. I make YouTube videos for Danish learners, but the voices are often inauthentic and too robotic. ElevenLabs gives voice over artists the chance to record their voice in detail and this provides great results. Not only can I record my own voice, but I have also been able to find other native speakers with great results. The multilingual option has also made it possible for me to mix both English and Danish together so learners can hear both in, for example, a phrase video! Love it! I also really love the ability to create a chat bot!! That is actually what initially attracted me to ElevenLabs. Liam J.

Lots of optionsThere are lots of voices to choose from, and interesting ways to get them to pronounce the words correctly. Tone of voice was a little harder to get right, but for the most part I have been able to figure it out adequately. I like that you can use multiple voices in a single project, so, for example, you can have each character in a book have a different voice. But wow that's a lot of work, and I haven't decided if it's worth it. I may come back to the books in the future and modify them. Since Elevenlabs saves the books in an easy to find dashboard, that will be eminently possible. It lets you organize your book into chapters, and the export function is easy to use. It was a lot of work to sort through the voices and decide which one was best for my project. I don't know how it could be improved. Since my books are science fiction, with aliens, I have some unusual names, I had to figure out tricks to get the voices to pronounce each name correctly, and occasionally (not often) it would pronounce the name right in one paragraph, then give a different pronunciation in another paragraph. Just means you have to be on your toes and catch these things. LeAnn R.
