Gradium’s natural-sounding, low-latency voice makes practice in my app, Eloqa, feel like a real conversation. I also appreciate how reliable it is and how much control it gives me over voice parameters. On top of that, the voice-design feature has been especially useful, letting us create the coach’s voice from a single prompt. Review collected by and hosted on G2.com.

As of our latest testing, Gradium speech-to-text model was not precise enough for our use case. It could be better now. But Gradium text-to-speech models are top-notch. Review collected by and hosted on G2.com.
