• Google Assistant — compatible with Google Home devices and many smart home products, this assistant controls gadgets, searches the internet, and beyond.
• Apple Siri — integrates with Apple’s HomePod, iPhones, iPads, and other Apple devices and controls smart home devices Apple’s HomeKit, plays music, sets reminders, and more.
• Microsoft Cortana — mainly integrates with Microsoft products for limited IoT applications.
• Samsung Bixby — available on Samsung smartphones and smart devices, this voice assistant can control gadgets, search the web, and handle Samsung ecosystem-specific tasks.

Besides the above popular solutions, there are alternative options for specific use cases. These are, for example, AliGenie for retail and shopping in China, XiaoAI tailored to Xiaomi’s smart home products, Kakao i for smart devices in the Korean language, and Line Clova for Japanese-language voice assistance.

Combining voice assistance with your IoT ecosystem extends beyond just convenience. It can offer hands-free operation of medical devices or automate industrial processes — the possibilities are almost limitless. Read on to explore other benefits of these innovative solutions.

Benefits of Voice Assistance in IoT

An IoT voice assistant offers hassle-free management of your smart devices and equipment. Let’s see the advantages this solution provides:

Enhanced User Experience

IoT voice control presents a new level of accessibility and user-friendliness. Users can effortlessly manage their devices with just their speech. Particularly, voice assistants offer the following perks for consumers:

• Simplified device management
• Hands-free operation
• Phone-free control via devices like smart speakers
• Better accessibility for people with disabilities or those facing challenges in traditional device control

By leveraging a combination of IoT and voice assistance tech, users can set thermostat preferences, check weather updates, or shop online without even touching their devices.

Efficiency and Automation

Using a voice assistant in IoT lets you automate various processes. You can configure the IoT devices of your ecosystem according to your needs and give them voice commands that they will execute. Consider a smart factory scenario where worker-voiced commands simplify complex machinery operations or a healthcare setting where medical professionals access patient information hands-free.

Scalability and Adaptability

An IoT voice assistant works well in different scenarios. You can either manage a smart home ecosystem or streamline industrial workflows and your operations as necessary. You can also integrate voice assistance-enabled devices into your systems and control them, along with other equipment.

Data Insights and Analytics

Voice data lets you analyze your end-user behavior and preferences to bring your customers more tailored solutions. If you’re using IoT device voice control within your company, let’s say, a manufacturing plant, you can study the obtained data for insights into potential workflow improvements.

Get a Consultation

An IoT voice assistant is a complex combination of various components. Let’s go through each of them in greater detail:

1. Voice input — a user command or query captured by a microphone or voice-enabled device
2. Speech recognition — a technology, usually automatic speech recognition (ASR), which processes the voice input and converts speech into text
3. Natural language processing (NLP) — a combination of algorithms that analyze the text to understand what the user wants
4. IoT devices — smart appliances, sensors, actuators, or machinery that use voice assistance tech and can be controlled by voice commands
5. Cloud services — a part of the voice IoT systems that stores voice data and enables its processing
6. Decision logic — an algorithm responsible for decision-making, which interprets user intent and comes up with relevant actions
7. Device control — an action that occurs after the IoT device processes the command, e.g., turning on the light or setting up the indoor temperature
8. Feedback and response — a response the voice IoT system provides to the user after completing the action
9. Security and authentication — measures that ensure protection of voice and user data
10. IoT Data analytics and learning —  data analytics and ML tools that help the IoT system improve voice recognition accuracy and adapt to user preferences

Examples of Voice Assistance in IoT

As already mentioned, plenty of IoT smart applications involve voice assistance. Here are just several of them:

Smart Home Integration

Integrate an IoT voice assistant into your smart home ecosystem to control your gadgets conveniently. You can embed the following solutions with voice control:

• Smart lighting systems
• Security systems
• Multimedia systems
• Climate control solutions
• Sleep enhancement solutions
• Personalized shopping assistants
• Energy management solutions
• Assistants for older adults and people with disabilities

Or you can simply leverage smart speakers by Google or Alexa to perform simple tasks like setting reminders or turning on the TV.

Healthcare and Medical Devices

Use an IoT voice assistant in healthcare to improve patient safety and streamline workflows for medical professionals. For example, patients can easily share health information by just talking to medical systems, making remote patient monitoring simpler. Or they can leverage voice-activated medication reminders to stay on track with their treatment plans.

Industrial and Manufacturing

An IoT voice assistant makes industrial processes more efficient by offering hands-free control in manufacturing, supply chain, and logistics. For instance, factory workers can use voice commands to activate the necessary actions within their equipment.

Retail and Customer Service

Voice assistants are prevalent in retail and customer service. In-store, customers can use this tech to receive recommendations or ask questions about products. Businesses, in turn, can leverage chatbots and virtual assistants to offer top-notch customer support.

Agriculture and Environmental Monitoring

Combining IoT and voice assistance in the agricultural sector lets farmers leverage precision farming techniques with voice-activated controls, e.g., to manage equipment or observe their crops. It’s also possible to use voice assistants for environmental monitoring, for example, adjusting heating, ventilation, and air conditioning systems to ensure optimal climate conditions.

Challenges and Considerations

When dealing with voice control in the Internet of Things, it’s crucial to get ready for certain limitations. Here are some of them:

Privacy and Security Concerns

Since users exchange voice data with their IoT devices constantly, ensuring privacy and robust protection is essential. Consider implementing encryption and access control management system, as well as providing secure data storage. It’s also best to educate your users about privacy settings.
