A conversation app could give learners guided scenarios such as making an appointment or discussing a journey. Practice should have a clear level and purpose rather than relying on an unrestricted chat screen.
If automated feedback is used, it should be presented as a suggestion that can be wrong. Learners need understandable corrections and opportunities to retry. Voice recordings require clear consent, storage choices and an alternative for people who cannot or prefer not to speak.
Start with a small set of carefully reviewed conversations and test them with the intended learners. Include different accents and unexpected answers. The app could support practice between lessons, without claiming that an automated score independently certifies fluency or replaces a teacher's assessment.
