What are Voice Assistants?

Voice assistants are wonders of the modern smart home. Through them, there is a vast ocean of information available and with smart home integrations, they can physically influence the environment around them.

These assistants are embedded in smartphones and smart speakers. They don’t just listen, but also interact with you. Hands-free, you’re able to play movies, ask questions, find music, read out recipes, get delivery updates, check the weather, and more!

Through artificial intelligence, voice assistants' understanding of human commands gets better each day. Increased interconnectivity with other smart devices, help us achieve a more futuristic automated home!

Features of Voice Assistants


Voice assistants are able to recognize multiple voice profiles. Correct vocal recognition is important for these technologies to ensure users keep using them.

There have been huge strides in the deep learning technologies behind voice assistants to continually improve the accuracy of voice recognition. This helps them provide relevant answers to questions. 

With the technological complexity in natural language processing, it is no surprise that Google, with its Google Cloud infrastructure; Amazon, relying on Amazon Web Services; and Microsoft, with Azure Cloud, are leading the charge in this industry.

Smart Speakers

Aside from the voice assistant’s smartphone applications, integration with smart speakers broaden their usability and function.

Compared to smartphones, smart speakers are equipped with better (and multiple) microphones standing by for easier interaction around the home. Of course, they have better speakers too. The audio quality introduces better interaction to the home. 

Newer smart speakers have evolved into smart displays, employing excellent screens with touch functionality.

Compatibility & Smart Home Integration

Voice assistants have been designed specifically with smart homes in mind. 

While competition between brands benefits customers, it can lead to a patchwork of compatibilities, with some devices supported and others not. Generally speaking, you’ll always be able to find compatible devices in one brand’s ecosystem or another.

Smart home device manufacturers and small competitors work fast to satisfy users’ compatibility needs, to broaden their reach. In addition, there are integration platforms such as IFTTT which try and bridge the compatibility gap between devices.

Supported Languages

For people in countries where English is not the first language, it’s exciting to be able to interact with voice assistants in their mother tongue.

Apple is one of the leading brands when it comes to the number of languages supported. Siri’s features can be accessed in more than 21 languages. Some dialects are even covered. There’s a good chance your language is supported, try it out!


Privacy is an ongoing concern of many who have smart speakers and displays or who are considering investing in one.

The idea of placing microphones and video cameras in your home, and allowing servers to remotely access them at all times is too much for some people. While these device manufacturers have some of the best security protocols in the world, any IT device can be hacked which strikes fear into a lot of people.

Manufacturers are coming up with ways to satisfy the privacy concerns of users. Alexa has a “Mute” option on the Echo device so you can disable all microphones. There is also a shutter on the Amazon Echo Show to block the camera until you want it.

Device manufacturers have privacy options around the storage lifespan of audio clips, so people can choose to have their private information deleted from cloud servers.

This is an area that will continue to evolve, as governments catch up and start legislating in this area.
