AlexaDev Tuesday: Alexa Dialog Management Allows Capture of Multiple Slots

One frustration many Alexa skill developers have is the rigidity of the interaction model. Sometimes your skill needs to get more than one piece of information from the user in order to fire its next function. Thankfully, the new Alexa dialog management tools allow for capture of multiple utterances in a single interaction.

 

User Experience

 

In his recent post on the Amazon Developer Blog, Justin Jeffress says:

During Alexa Dev Days, my colleagues and I have been leading a voice design workshop that focuses on voice-first experience design and leans on dialog management to simplify collecting a set of required slots that an intent needs to perform its task for the user.

Recently an attendee asked me, “I need to get the user’s address based on zip code or city and state. Can I do that with dialog management?” The answer is, yes!

In that case, you’re looking for the condition A and B or C, where A is the zipcode, B is the city and C is the state. You can mark all 3 slots required and then hook into the state machine and jump out of dialog management if the condition has been met by setting the dialogState to COMPLETED and returning the slots.

 

New to Dialog Management?

Dialog Management tools are powerful, but they can be confusing and their use often demands that the developer have a basic grounding in state management. Here are some resource links that should help get you from zero to proficient with Alexa state and dialog management.
