About

Coval is a simulation and evaluation platform designed to accelerate the development of reliable AI agents across chat, voice, and other modalities. By automating the testing process, Coval enables engineers to simulate thousands of scenarios from a few test cases, allowing for comprehensive assessments without manual intervention. Users can create test sets by adding customer transcripts or describing user intents in natural language, with Coval handling the formatting. The platform supports both text and voice simulations, facilitating the testing of AI agents against a set of scorecard metrics. Comprehensive evaluations of agent interactions are provided, enabling performance tracking over time and root cause analysis of specific runs. Coval also offers workflow metrics that provide observability into system processes, aiding in the optimization of AI agents.

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.

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 ;-)
