Voice User Interface

Blog Home » Latest » Voice User Interface

Voice user interface helps us interact with the device or an app through voice command. With more digitalization, it has become a common trend that people often tend to avoid doing things manually on the devices as it even causes screen fatigue. 

So with all this, the voice user interface usage has reached a new level all together. All the leading companies of the world have developed and are still developing many voice controlled devices. Apple’s Siri, Google’s Assistant and Amazon’s Alexa are some common well known examples.

How does it work?

It is actually a combination of various AI technologies. The user’s intent is understood by AI and returns a response to the device. The addition of GUI and sound effects to VUI improves the user experience.

Advantages and Disadvantages

Some of the major advantages of VUI are :

  1. Ease of use
  2. No need of typing
  3. Makes things fast
  4. Less strain on eyes

While on the other hand there are also some disadvantages of VUI, which are :

  1. Misinterpretation
  2. Lack of accuracy
  3. Not practical at public places   

Why Voice User Interface

Majority of the people today prefer searching by voice rather than typing. Even the use of voice controlled devices has seen a tremendous growth in recent times.  The increasing popularity has made it important to make the UI and UX accordingly. 

A good knowledge of human communication that includes the tone understanding, level of misinterpretation, etc. is required to create a successful interface. So a thorough research and observations are required along with proper analysis to achieve an efficient design.
