The Benefits of Smart Speakers

Smart speakers offer a range of benefits that have made them an integral part of many households. The key advantage is the convenience they provide. With a simple voice command, you can check the latest news and weather, play music, set reminders, and much more. This hands-free interaction eliminates the need to operate different devices or use a smartphone.

Another benefit is their ability to integrate with other smart home devices. Whether it’s turning on lights or adjusting the thermostat, they can act as a smart home hub, allowing you to control other compatible devices without lifting a finger.

Furthermore, research commissioned by the UK’s OFCOM in 2022 showed smart speakers can also be beneficial for individuals with disabilities or mobility issues. By providing a hands-free and voice-activated interface, these devices can empower users to independently control their environment and access information much more easily.

How do Smart Speakers Work?

At the heart of every smart speaker is a virtual assistant, such as Alexa, Siri, or Google Assistant. These assistants use voice recognition and natural language processing (NLP) to understand and interpret human speech.

You’ll find that smart speakers are usually equipped with an array of microphones for capturing audio. This audio is processed and analysed by the virtual assistant, so it can provide relevant information or perform a requested task.

As with all new technology, smart speakers aren’t 100% foolproof and can sometimes misinterpret a command. However, by leveraging machine learning and artificial intelligence, these devices can adapt and improve over time.

What is a Wake Word?

A wake word is a predefined word or phrase that triggers a smart speaker to start listening for a command. For example, with an Alexa-enabled smart speaker, you would say “Alexa” followed by a command or question. Similarly, with Siri, you would say “Siri,” and with Google Assistant, you would say “Hey Google” or “OK Google.” These wake words are designed to be easily recognisable by the virtual assistant. It’s important to note that voice commands are clear and concise to ensure accurate interpretation. This includes enunciating words clearly, and avoiding as much background noise as possible.

Smart Speakers and Your Privacy

Smart speakers have raised privacy concerns since their introduction. As we touched on earlier, each time you interact with a smart speaker, an audio recording is sent to a server to be analysed. Amazon, Apple and Google may use certain recordings and transcripts to improve the service that their virtual assistants offer.

Also, since smart speakers are always listening for the wake word, there is the potential risk of unintended audio being captured. Instances have occurred where words that sound like the wake word and dialogue off the television have accidentally triggered recordings. To address these concerns, look out for the following features that help protect your privacy:

A Visual Indicator

A light will usually come on or change colour to tell you when a smart speaker is active and listening for a command.

A Microphone Off Button

This could be a physical button or a mute option that can disable any microphones.

The Ability to Delete Your Audio History

Alexa, Siri, and Google Assistant allow you to delete audio recordings that they have stored.
