Principles of VUIs

What is Voice User Interface (VUI)?

• An interaction model where a human interacts with a machine and performs a set of tasks at least in part by using voice.

• The process designers use to build interfaces in software or computerized devices, focusing on looks or style.

• A type of assistive technology that reads digital text aloud.

• The integration of digital information with the user's environment in real time.

The first generation of VUI is dated to the 1950s. In 1952, who built a system called Audrey?

• Bell labs

• Microsoft

• Google

• IBM

From 1980s to 1990s, for the first time in history, a digital system could recognize human voice-over calls and perform the tasks given to them. At this moment, what is the digital system called?

• Voice assistant

• Interactive voice response (IVR)

• Dictation system

• Embodied conversational agents (ECAS)

We need to build a conversation that seems natural, understands the user’s ___, and responds intelligently.

Which one of the following statements is correct regarding the principles of designing VUI?

• Users need as much as possible information to complete the task.

• To make sure the interaction is successful, we need to provide a wide range of sentences, phrases, and words.

• We should provide only one utterance per intent to improve the accuracy of the system.

• We need to provide complex information to the conversations as human communications.

A high-utility interaction is about performing a very specific task, for example...

• Requesting that the AC in the bedroom be turned off.

• A user wants to buy a laptop.

When a person says: "Winter is coming." We know that the user is referring to a Game of Thrones quote and wants a response that is more context dependent. In this case, humans typically know what the intent is due to what?

• Shared world information.

• Superpower.

• Social knowledge.

• Cultural background.

"Speaker: Max, what is the height of Mt. Everest?

Listener: Mt. Everest is 8,848 meters high.

Speaker: Which one is the second highest?"

There is one principle that helps the listener to know how to continue this conversation. This principle is ?

• Understanding context.

• Predict the content.

• Cooperate and respond.

• Keep the conversation efficient.

We tend to give a face to a person or object even if they have none. This is called?

• Euphemism

• Metaphor

• Anthropomorphism

• Empathy.

We have an intent in mind and we want answers from the assistant. We simply want to complete a task. This type of conversation is called?

• Intent-based conversations

• Casual conversations
