Conversation design and grounding strategies
Conversation design is one of the core skillsets required to create engaging and effective voice and conversational experiences. UX Mag recently wrote about how the role of conversation designer will be one of the fastest growing UX roles in 2020.
But what exactly is conversation design? And what does a conversation designer actually do?
This week, we're joined by Jon Bloom, Senior Conversation Designer at Google to find out.
We discuss the role, what's involved, Jon's prior experience, the resurgence of enthusiasm in the voice community, as well as some conversation design techniques you can use to start creating engaging conversational experiences.
Conversation design techniques
One of the highlights of the conversation is Jon's take on errors.
Within the conversation design community, most people talk about 'error recovery', which is recovering from situations in a conversation where things go wrong. For example, if a user asks for a pizza, and the system says 'what flavour', what happens when the user says a flavour that the system doesn't have? Or if the system mishears the user?
Recovering from these situations is typically known as 'error recover', but Jon's perspective is different and refreshing.
Jon mentioned that within all conversations, there are no such thing as errors. There is simply 'grounding'.
Grounding includes anything and everything the two people do within a natural conversation in order to ensure understanding.
For example, if a user asks for a hotel room for Tuesday, the system might confirm with 'Here's the rooms I found for Tuesday'. Confirming that it heard Tuesday is a form of grounding.
In the pizza example, where the user asks for a flavour the system doesn't have, the system might respond with 'I'm sorry, we don't have Hawaiian, but we do have farmhouse'.
These aren't 'errors', they're natural parts of human conversations and the things we do to ensure both parties are on the same page.
We get into some great detail on this with Jon, as well as plenty more conversation design techniques.
