Thanks for sharing! I tried using it for Thai language coming from English and found that the app understands me well! But I couldn’t understand it at all. It replied to my turns with very long messages (20+ syllables) in pure Thai and spoke with an unnatural rhythm which made it hard to pick out words or phrases. The foreign alphabet made it really difficult too. I tried changing some settings in the bottom left menu and it started speaking English to me too, but I found it unbearably slow. At one point it asked me if I wanted it to speak in pure Thai or a mix and then ignored my answer. Ultimately as a beginner I don’t think Issen will work for me very well as-is. Happy to check back in the future!
