What are voice assistants and how do they work?
You may have guessed from our introduction what a voice assistant is, but let’s try to provide a more precise and simple definition to help you understand the topic better. A voice assistant is an artificial intelligence-based software designed to understand your voice commands and perform specific actions or simply provide you with the information you’re looking for. Its purpose is to act as an intermediary between you and your devices, freeing you from the need to use screens and keyboards.
But how does it work? This system is based on three main technologies: speech recognition , which captures your voice through a microphone and converts it into text; natural language processing (NLP) , a technology that allows machines to recognize the meaning and intent of your request; and finally, artificial intelligence , which processes everything. The latter seeks the best response or action, then responds to you, usually with a synthesized voice. While it may seem like a complex process, it actually happens in a matter of moments.
Having identified these three components , over time, companies have created products that can integrate them; in fact, today we have an infinite number of smart devices, which, thanks to home automation and smartphones , amplify their potential, allowing you to manage an entire ecosystem of connected products, from smart light bulbs to household appliances , directly with your voice.
Types of voice assistants
We can classify voice assistants into two broad categories, depending on the platform on which you use them.
Voice assistants for the home (smart speakers and displays)
You can buy various smart products that belong to the category of home voice assistants, which are nothing more than software that powers smart speakers such as Amazon Echo Dot or Google Nest Mini , and smart displays such as Amazon Echo Show or Google Nest Hub .
Voice assistants for Android smartphones
Another large category is that of voice assistants for Android smartphones , in which the software is integrated into the operating system. Very often, you’ll find it pre-installed, as is the case with Google Assistant . This doesn’t mean you don’t have a choice, however; you can download alternatives from the Play Store. The Amazon Alexa app , for example, can be installed and selected as the default assistant to enhance your experience with the Amazon ecosystem . Several manufacturers, such as Samsung , have developed their own assistant, Bixby , but we could list many more examples.
The best voice assistants for home
Choosing the right assistant for your connected home depends largely on the ecosystem of devices you have or want to integrate. You might be wondering: which is better, Siri or Alexa? Let’s take a closer look.
Amazon Alexa
Alexa is among the best-known and most used digital assistants , with which you have the possibility of connecting many Alexa-compatible devices , both from Amazon’s Echo line and from other manufacturers.
Its ecosystem is based on ” Skills ,” which you can identify as voice apps that expand its capabilities. With the Alexa app, you also have the option to create custom ” Routines ,” which are sequences of actions activated by a single command. For example, by saying ” Alexa, good morning ,” you can turn on the lights, start the coffee maker, and listen to the news. For more information, we recommend our guide How Alexa Works .
Pros:
- It integrates seamlessly with Amazon services (Amazon Music, Prime Video, Amazon Shopping and Alexa Skills)
- Skills for anything (over 100k).
- Excellent product for home automation.
Against:
- Answers to complex questions are not as precise as Google’s.
- Privacy and constant listening.
- Some smart home devices are not supported or require bridges and extra configurations.
Google Assistant
Google Assistant is more than an alternative to Alexa; it has the intelligence to understand the context of conversations. It obviously uses Google’s search engine and provides relevant answers . Integration with the Google Home ecosystem is excellent, and device management is simple and seamless. It’s a smart choice for managing complex commands and answering general knowledge questions.
Pros:
- Very precise responses and basic commands (alarms, calls, apps) that also work offline.
- Understands context immediately thanks to advanced speech recognition.
- Integrates with Android and Google services (Gmail, Google Calendar, Google Maps, YouTube, etc.)
Against:
- The number of compatible devices is less than Alexa (e.g. non-Google smart speakers)
- Privacy and data tracking.
- Custom routines are less intuitive and less powerful than Alexa’s.
Apple Siri (with HomePod)
If you’re a user deeply connected to the Apple ecosystem, Siri and its HomePod are almost an obvious choice. Integration with your iPhone, iPad , and Mac is seamless; in fact, the HomeKit platform , while more selective, guarantees high standards of security and privacy. However, if you’re wondering whether Siri or Alexa is better for home automation , the balance often leans toward Alexa or Google, due to their greater flexibility and support for more devices .
Pros:
- Full integration with the Apple ecosystem (iPhone, iPad, Apple Watch, Mac, Apple TV, and HomePod).
- Quick and customizable voice commands (e.g. setting Siri shortcuts).
- High privacy compared to other assistants (Siri stores voice commands locally).
Against:
- It supports fewer apps and smart devices than competitors Alexa and Google Assistant.
- Less precise speech understanding.
- Weak smart home features.
Other voice assistants for home automation
As we mentioned, there are also solutions developed by specific manufacturers, such as Xiaomi or Samsung with SmartThings . However, these tend to focus on their own brand’s devices, offering a less universal experience and more limited support for products from other brands.
The best voice assistants for Android
Even on your smartphone, choosing the most suitable assistant for your daily activities can make a difference.
Google Assistant
If you use Android, Google Assistant is almost always the best voice assistant. It’s pre-installed and developed by Google , and it integrates deeply with the operating system. It can read your notifications , send messages for you, initiate calls , set reminders , and control phone functions with unparalleled precision. Plus, it offers excellent Italian support.
Pros:
- It is pre-installed and integrated into all system functions.
- Complete voice control for searches, event creation, translations, and more.
- Allows you to create custom actions with a single voice command.
Against:
- Always-on “ Hey Google ” recognition affects battery life.
- Privacy and voice recordings raise concerns.
- In noisy environments it does not always respond coherently.
Amazon Alexa
With the Alexa app for Android, you can take the Amazon assistant experience with you wherever you go. It’s the best choice if you already have Echo devices, as it lets you manage your home automation and use skills even when you’re away. It works very well, but its system-wide integration can’t compete with Google Assistant.
Pros:
- Allows you to set up and manage lights, plugs, thermostats, cameras and other Alexa-compatible devices.
- You can quickly create daily routines (e.g. “Good morning” = turn on lights + weather + news).
- It lets you update your Echo device settings, listen to music, change alarms, timers, and more.
Against:
- Performance isn’t always top-notch on some smartphones.
- Interface not always intuitive.
- If you have multiple Amazon accounts or multiple Echo devices, syncing issues may occur.
Samsung Bixby
If you have a Samsung smartphone , you have Bixby , a very powerful virtual assistant for controlling your device. It can execute complex commands within Samsung apps (for example, you can tell it: “Open the gallery, find yesterday’s photos, and create an album called ‘Memories’ ”). However, it lacks in general knowledge questions and home automation control.
Pros:
- Integration with Samsung devices
- It allows you to create custom automations based on location, time, device status, and so on.
- You can launch apps, take photos, change music, dictate messages with your voice.
Against:
- Unlike Google Assistant or Alexa, Bixby is less compatible with external, non-Samsung apps.
- It doesn’t integrate well with Google services or non-Samsung smart home devices.
- Not widely used.
Other Voice Assistants
On the Play Store, you can also find less popular alternatives to those just listed. Hound , for example, is known for its speed, while Replika is designed to create a real emotional connection. Like ChatGPT, the app now with voice support (Voice Mode) can be used as a talking assistant on Android. For more information, you can check out our guide on How to make ChatGPT talk and turn it into a voice assistant .
Which voice assistant should you choose?
Choosing the best voice assistant isn’t easy; it depends on many factors: the device you use, your ecosystem (Android, Apple, Samsung, etc.), the apps you use most, and the level of integration you want with your smart home. Below is a comparison table of the four most popular voice assistants available in Italy: Alexa, Google Assistant, Siri, and Bixby .
