In this video, Emmanuel Henri introduces voice UX and the factors of a successful voice conversation with any voice activated systems.
- [Instructor] It wasn't long ago that talking to a box on your kitchen countertop would have been cause for concern. But over the past few years, voice-controlled systems have slowly grown in popularity and the offering of these types of device has also grown to support this demand. As soon as we start interacting with a device by talking to it, we are experiencing Voice UX. So for anyone building interactive voice systems, a certain amount of thought and due process needs to be taken into consideration. I call this process the trifecta of Voice UX, where we can properly evaluate whether the user experience is pleasurable or frustrating.
Let's take a look at the major elements that need to be taken into consideration when building such a system. The first part of the trifecta is comprehension, which is the most important step in a successful interaction. Much the same way that a person might need to clarify a request, the device may need to ask additional questions to be 100% sure that the meaning of the user's command is properly understood. The second factor and what is often missed with many systems is the personality of the system.
Do we enjoy having a conversation with the system? Can we distinguish the difference in talking to the system versus a person? And finally, do we get accurate results? The whole purpose of a Voice UX is to be able to give the person what they need. It might be a request to convert grams to pounds, turn on the lights, or play a sound from a library. Did the device provide what we asked for? We'll explore these factors in detail in the following chapters, including how to evaluate them against our trifecta.
And I'll demonstrate some examples of successful voice-activated systems.
