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 ;-)
