I'm trying to solve the problem of unlimited conversation practice for various languages with "CallAnnie", an iOS/android app with various kind of AI friends, powered by real time voice and avatars.

The interface is specifically made for advanced learners that want to simulate a conversation as close as possible to a real one (in terms of latency and without pushing any button). Learning to respond fast in a new language is important, so we're trying to keep a natural pace.

We support audio or video-calling the characters (with subtitle translations), guided conversations and we recently added mini games to learn vocabulary.

You can see a quick intro and demo video here: https://www.sixthtone.com/news/1013961

We don't have a Dutch speaking character in the default character list, but you can follow this link https://app.callannie.ai/a/mhLnHflAyf1Ygb0D0wm6 after installing the app to use a custom character speaking Dutch (or you can create a custom character).

If you'd like to try it, check out: callannie.ai . I would love to get your feedback (here or francesco a t callannie.ai) and suggestions - we're trying to solve this speaking practice use case.
