question

I should add that, my understanding is that, it could perhaps be achieved by account linking. However, the Interaction Model requires values to be entered for Custom Slot Types. What values should be given if the value is expected to be dynamic/open-ended? Thanks

No. You can't. Please search the forum for explanations of why, and suggestions of what to do about it. There are plenty of threads on the topic.

I have and found this post https://forums.developer.amazon.com/forums/thread.jspa?threadID=10165 and that's what got me a little confused. It was mentioned that the Drive Time skill does something like this. The example was that the user's enter the names of destinations (for example, "nora's house") via account linking, and then compute the string similarity between what Alexa hears and strings in the database. However, how should the values of the Custom Slot Type be defined? My understanding is that it's a static list. When the user adds "nora's house" into our system's db, it needs to somehow be reflected in the Custom Slot Type values - right? Message was edited by: mun3 Message was edited by: mun3

If I remember right, it uses a "generic slot". You can search the forum on that technique too. It is basically creating a slot/intent so generic that Alexa will try to match it to anything. Alexa is not built for this. You can trick it into it, but the quality is poor. If you are just doing a flashy demo, go for it. If you want to create a wide release skill of quality, I do not recommend this option.
