Michaels Voice Assistant
Voice Premisses
There are a few things to be considered when it comes to voice while developing an assistant like this.
First, you have to have a help guide, customers might get lost and they might need a way to know everything the device is capable of.
Second you have to be prepared to follow-up intents which are often common and a must-have if you want to provide a seamless experience. This way users can talk naturally as they would talk to a real person. An interesting bonus feature that would increase customer engagement is to have alternative responses when users are not understanding what the assistant is telling them to do. You can see an example of that on the video above when the customer doesn't understand where he should go and the assistant shows him an alternative response by showing him a picture of the location he should go.
Lastly, since all retail establishments want to increase their revenue, why not use a voice assistant to do that? It's an interesting strategy to add selling opportunities and call to actions related to what customers are asking for. Are customers asking where the blank canvas are? Suggest to also check the art supplies on the adjacent aisle for half price. This way you would not only help customers in a more efficient way but would also increase sale opportunities.
