I have used TalkPal for Catalan. I found it slightly superior to ChatGPT, especially, I find the feedback about performance, daily/weekly summary emails, the suggested responses, and the gamified experience to be motivating. The conversations use voice and text input, and audio and text output. I believe they also have a Dutch version.

It is not quite what you are looking for, but I also liked Lingoclip for both Catalan and Spanish. I had exceptional difficulty training my ear to distinguish speech sounds, so recognizing words in song lyrics was helpful.
