Voice Assistants Explained: Siri, Alexa and Google for Seniors
A voice assistant is the part of your phone, tablet or smart speaker that listens when you speak and does what you ask. You say a few words out loud, and it sets a timer, plays the radio, rings your daughter or tells you the weather. For an older person, or for anyone whose hands or eyes are not what they were, that can turn a fiddly job into a simple sentence. This guide explains the three you will hear about most in Australia, in plain English, with no jargon.

Quick answer: what is a voice assistant?
A voice assistant is a helper you talk to instead of type to. You wake it with a phrase, then ask in everyday words. The three main ones are Siri on Apple devices, Google Assistant or its newer version Gemini on Android phones, and Alexa on Amazon Echo speakers. They are best for quick, hands-free jobs: calls, timers, reminders, music, the weather and simple questions. You do not need to buy anything special to start, since Siri and Google are already on the phone in your pocket.
How a voice assistant works
Every voice assistant works the same way. You say a wake word to get its attention, then your request. On an iPhone or iPad you say “Hey Siri”. On most Android phones you say “Hey Google”. On an Amazon Echo speaker you say “Alexa”. After the wake word, you simply talk. “Set a timer for ten minutes.” “What is the weather in Brisbane tomorrow?” “Ring Margaret.” The device listens, works out what you meant, and does it or answers back.
Siri, on iPhone and iPad
Siri is Apple’s voice assistant, and it is already built into every iPhone and iPad. There is nothing to download. You turn it on in Settings, then say “Hey Siri” followed by your request, or hold the side button. Siri is handy for calls, messages, timers, reminders, alarms and simple questions, all without finding your glasses or tapping a small screen.
Apple has been adding cleverer AI features to recent iPhones under the name Apple Intelligence, and a much-improved Siri is on the way during 2026. Those newer features only work on recent models, such as the iPhone 15 Pro and the iPhone 16 and 17 ranges. If you have an older iPhone, the everyday Siri still works perfectly well for calls, timers and reminders, which is what most people use it for anyway.

Google Assistant and Gemini, on Android
If you have an Android phone, such as a Samsung, the Google voice assistant is built in. You say “Hey Google” and ask away. It does all the same everyday jobs as Siri: calls, reminders, timers, directions and questions.
One thing is changing, and it is worth knowing so it does not catch you out. Google is gradually replacing the older Google Assistant with a newer, smarter version called Gemini through 2026. On a brand new phone you may see Gemini already. On an older phone you may still have Google Assistant for a while yet. Either way, the wake phrase stays “Hey Google” and the simple jobs work just the same, so there is nothing you need to do.
Alexa, on Amazon Echo speakers
Alexa is Amazon’s voice assistant, and unlike the other two it usually lives in a separate little speaker called an Echo, which sits on the bench or the bedside table. You say “Alexa” and then your request. Echo speakers are sold here at Officeworks, JB Hi-Fi, Harvey Norman and Amazon Australia, and they range from a small round speaker to one with a screen for video calls.
An Echo is popular with older people because you do not need to hold or look at anything. From across the room you can play the radio, set a kitchen timer, hear the news, add to a shopping list, or ask the time. A newer, chattier version of Alexa is being rolled out in some countries and is expected in Australia in time, but the Alexa sold here already does the everyday jobs well.
What voice assistants are good for
The real value is in the small, hands-free jobs that are awkward any other way. Setting a timer while your hands are covered in flour. Ringing a family member without scrolling for their name. Hearing the weather before you hang out the washing. Playing your favourite station without hunting through menus. None of it is essential, but together it takes a lot of small frustrations out of the day.
A sensible word on privacy
People often ask whether the device is always listening. It is waiting for its wake word, but it is not meant to record or send anything until it hears that word. Even so, a little common sense helps. Do not read out passwords or card numbers to a voice assistant, and if you would rather, you can open the settings on the phone or in the Alexa app and delete your voice history or turn the microphone off when you want quiet. Treat it like any helper in the house: useful, but not the keeper of your secrets.
Easy first things to ask
- “What is the weather today?”
- “Set a timer for fifteen minutes.”
- “Remind me to take my tablets at eight tonight.”
- “Play ABC Radio National.”
- “Call Margaret.” (once her name is in your contacts)
Start with one or two of these. Once they feel natural, the rest follows on its own.

FAQ: voice assistants for seniors
Do I need to buy anything to use a voice assistant?
Not necessarily. Siri is already on every iPhone and iPad, and the Google assistant is on every Android phone. You only need to buy something, like an Amazon Echo, if you want a standalone speaker to talk to.
Is it always listening to me?
It waits for its wake word and is not meant to record until it hears it. If it makes you uneasy, you can delete your voice history in the settings or switch the microphone off when you want quiet.
What is the difference between Google Assistant and Gemini?
Gemini is the newer, smarter version of Google’s assistant, and it is gradually replacing the older Google Assistant through 2026. You still say “Hey Google” either way, and the everyday jobs work the same.
Which one is best for an older person?
Usually the one already on your phone, since there is nothing to buy or set up. An Amazon Echo is worth considering as well if you want something on the bench to talk to without holding a phone.
What if it does not understand me?
Speak a little slower and use simple, direct requests. If it still struggles, you can train it to your voice in the settings, and it tends to get better the more you use it.
