I'm currently developing a german skill for ordering a taxi. During the order process, the skill fetches the device location and prompts it to the user for confirmation purpose (e.g. Are you sure, you want to order a taxi to STREETNAME...?).
I created an "Confirm" intent which has utterances like "yes", "correct" etc. (all in german). Since about 2 hours now, alexa doesn't recognize the "ja" (german for yes) anymore. Instead of triggering the confirm intent alexa just makes that quick sound sounds, like it didn't understand, and then listens again. All the other utterances for the confirm intent are working fine.
Do you have any ideas on why this isn't recognized anymore?
