What is the role of Voice Revolution in Industry 4.0?

Introduction of Voice User Interface (VUI)

A new kind of User The interface is a voice user interface. It creates spoken human interaction with computers likely with speech recognition to recognize spoken instructions and to show an answer. The device organized with a voice user interface is known as a voice command device (VCD). The speaker-independent new VCDs have been introduced which may answer to many voices irrespective of pronunciation or dialectal effects. They are skillful at answering numerous commands at once. They are similarly able to provide proper feedback, sort out vocal messages, and precisely reproducing a natural conversation. AI Assistants allow us to control things like our thermostat, garage door, and other connected devices just by speaking.

Most suitable uses of Voice control in IoT

  • Home automation, home appliances like washing machines, television remote controls, and microwave ovens. IoT devices are an integral part of the bigger concept of home automation.
  • Automobiles: VUI has been added in Cars and vehicles. Voice command for cars should permit a driver to issue directions and not be diverted.
  • Health Care: IoT devices may be used to assist remote health monitoring and emergency notification system. Advanced hearing aids are the best example of a health monitoring device
  • Entertainment: A smart speaker having a touch screen is a smart Bluetooth device. It adds a conversational user interface with display screens to increase voice interaction with images and video.

Voice Assistants Are Taking Over Consumer IoT

More than Consumer IoT (CIoT), no industry felt the heat of the voice assistant battle in which voice assistant integrations became the primary focus for any CIoT product-centric company. Imagine a future in which every command is at the tip of our tongue. When we wake up our bathroom mirror can report the schedule for the day. During breakfast, we can ask the coffee machine for a latte, extra foam. On the train, our watch will tell us just how late we’ll be to work. In the office, our printer will pipe up, asking for more ink, please.

The entry point into the IoT

The entry point into the Internet of Things has been Amazon and Google’s smart speakers for several consumers. Voice control is one of the main drivers of smart home market development with the number of home voice devices predictable to reach 275 million by 2023 in the USA alone.

Digital Assistants are So Hot

  • German company major in the market and consumer data named Statista describes that the market for AI-driven personal assistants and bots will almost double in 2020, reaching more than $14 billion by 2022 with 1.8 billion active users.
  • Attractive greatly today every tech giant is making digital agents for their customers. Amazon’s Alexa, Microsoft’s, Apple’s Siri, and Google’s Assistant are prominent digital mediators.

Causes for being So Hot

  • Natural language is more spontaneous than web or mobile interfaces, which commonly entail a certain degree of a learning curve.
  • Boosted productivity
  • Personalization drives far beyond voice recognition. They pay machine learning to refine their replies and bring only applicable options built on customer likings.
  • Personal assistants may contact a huge variety of data
  • AI-aided assistants and innovations in the IoT get an entirely new level of communication between devices, people, and companies.

AI Voice Assistants

AI voice assistants generally take input by voice. A lot of them listen continuously for a prompt word, which makes hands-free use possible. If that’s not likely, we simply tap an icon to say our piece. We’ll find them in smartphones, smart speakers, smart TVs, and other “smart” internet-connected devices. The Google Assistants is a powerful AI that’s available on just about every Android device on the market. Most people allow voice Assistants for internet searches, media playback, message dictation, scheduling, and alarms. We may even control things like volume, Bluetooth, and WiFi.


  • Apple’s Siri                                   2011
  • Microsoft’s Cortana                     2014
  • Amazon’s Alexa                            2014
  • Google’s Assistant                       2016
  • Samsung’s Bixby                         2017

What is a Bot?

A Bot is a conversation-based UI. The conversation is based on language. It takes place on a general canvas. The canvas can be:

  • Chat Client: Skype, Team, Slack, Messenger
  • Voice: Echo, Cortana Skills, Siri, Google Now
  • App: Website, App

Scenario’s for Bots

  1. Question and Answers
  2. Systematize Helpdesk, Handoff to human if besides difficult
  3. Product selection and ordering
  4. Task Automation
  5. Proactive Assistance & Monitoring
  6. Expert Systems

Embedded devices with dialogue capabilities

  • Amazon Echo (2014) – home assistant device: It plays music with voice commands. Have the capability to Question answering, get weather, news. It replies to more complex questions, like “how many spoons are in a cup? Other types include setting timers and manage TODO lists.
  • The Voice-Activated Smart Clock: The unique features of the voice-activated smart clock is answering the questions, set the time, thermostat, and device control & queries

Dialogs are for bots like screens are for appsTraditional Application

  • The distinct fears and organize flows, correctly the same way:

Traditional Application

  • Main Screen
  • New Order Screen
  • Product Search Screen


  • Root Dialog
  • New Order Dialog
  • Product Search Dialog

Google Assistant coming soon ….

  • Google is locating its Assistant on wide-ranging third-party hardware.
  • It has declared that it’s going to be setting the Assistant on partner speakers, appliances, connected cameras, and much more.
  • It is already on the iPhone.
  • Google wants to ‘see’ as well as ‘hear’ our surroundings. For this purpose, it developed Google Lens that is an image recognition technology.

How to develop for the Google Assistant platform?


  • Developer, the platform of Google is known as Google actions that let us make software to cover the functionality of the Google Assistant, Google’s virtual personal assistant, across in excess of 500 million devices, with TVs, headphones, watches, smart speakers, phones, cars, and more.
  • We can build smart home Actions that let users control the Internet of Things (IoT) devices through Google Assistant. Building smart home Actions lets us connect, query, and control devices through our existing cloud infrastructure.
