It seemed like an impossible task some years ago but Artificial intelligence slowly and steadily is finding its feet in various businesses around the world. And on top of this if some years back anybody would have said that there would be Voice-based AI making buzz in the market in 2020 than he would have been labelled as a freak.
But in the recent years scenarios have changed so dramatically that Voice-based AI has kind of become a trend in today’s world. Iphone 4S brought this trend in the market by introducing Siri to the audience. Floodgates were open after this and world have been showered with various Voice-based AI since then such as Google Assistant, Alexa, Cortona and many more.
Now, you are reading this article because you are interested in creating a voice-based AI mobile app development or want it to be created for you. Whatever the case, you need certain type of skills and right kind of knowledge for that to happen and this article will provide you just that. But first let us take complete knowledge about VUI.
What exactly is VUI?
VUI stands for Voice User Interface and its main function is to let users interact with a system via voice commands. They serve the users with a hands-free and eyes-free way of interacting with a specific system and this is something that makes them very unique.
Some of the very famous voice user interface examples out there are Siri, Google Assistant and Amazon’s Alexa.
VUI consists of three layers that makes them work efficiently on OS and all the devices and these three layers are,
Reasons behind hype around VUI
It is a no brainer that speaking is more convenient than typing and any app that uses VUI will attract far more customers than the app that doesn’t. Users don’t want to get limited by the option of just typing, they would love to have both the options at their disposal to use them according to the situation. This is what prompting various companies to indulge voice technology in their products one way or the other.
Yes, we humans have put technology to a great use but there are still other benefits that the technology is ready to provide, all we have to do is unearth its full potential. Voice assistants can help us unlock the full potential of technology. Today, voice assistants are used mostly for opening messages or dialling a number but it can be put to many other tasks such as opening up a garage door, ordering a food delivery, starting up your car, making an appointment.
Most of the new discoveries that takes place around the world don’t try much to involve the specially-challenged in their plans. Since Voice assistant is of great assistance for the specially-challenged audience that is why we decided to label it as one of its benefits. Specially-challenged people are being served to great extent through this unique medium of help. They are now able to use their devices and applications which they were not able to do using visual user interfaces.
Difference between Video and other types of UI
Privacy can determined as one of the major concern and a point of real difference between these interfaces. It is quite possible to develop gesture-based, text-based and touch-based interfaces private but creating a visual based interface design can prove to an uphill task for creators out there.
Speed can easily be said as one of the other determining factor between voice user interfaces and other graphical user interfaces out there. Humans are more likely to pick the side of visual user interface as humans are inherently visual in nature and also because visual user interface provides faster responses in comparison to other interfaces. VUIs is certainly playing a catch up game in terms of speed.
Visual user interface does not enjoy the monopoly anymore as people are more open to trying new options such as voice-based interface and gesture-based interface. Voice takes in natural language and then converts it into a command for the Voice-based AI to perform it. While for gesture-based interface the function is to process certain type of gestures and then act according to it, for example Sony Play station.
Procedure for designing a voice user interface
Do thorough research on what is the need of the audience at the present moment of time. You need to have an outgoing approach towards your audience which will serve as a base for the success of your voice-over interface. Gather all the necessary information regarding the behaviour of your users, assemble all their needs and then act in accordance to that.
• Define the process
You have define the capabilities and shape of your product at this point of time. This will include various steps such as these.
These scenarios are pretty important and comes before the actual idea of the app. These scenarios will serve as high value for your users when you design them keeping in mind that why should someone actually think of using a VUI.
For mobile app developers out there sometimes it can be quite confusing to determine which scenario is more important. To get rid of this confusion, they can use a use case matrix.
The most important part about these scenarios is that they need to work well more effectively in comparison to its alternatives. Prime motive of this step is to find the easiest and most common cases that the users can benefit from. There are three factors that are associated with it and these factors are – Intent, Utterance, Slot.
There are two types of intents,

Design Guidelines for VUI
Since this concept is new to the users they might face some difficulty in getting it started. That is why you should be there helping them out beforehand.
Less is more in case of Video User Interface. The content that you are providing to the users should be full of meaning and understandable in one go.
The users should be made aware when the device is actively interacting. Cues must be given to the users when to speak and when the voice assistant is listening.
Confirmation of task being completed should be provided to the users. This will eliminate the need for user asking the VUI whether the task has been completed or not.
Some of the major challenges that are presented in front of VUI are namely
Voice user interface is good for the future but make it an unstoppable force we need to combine it with visual user interface. Google assistant and Siri are prime example of that. Both of them will balance out each other’s shortcomings and will complete even complete the most complete tasks for the users.
