Talking to your AI: a beginner's guide to AI voice assistants

An AI voice assistant lets you talk to artificial intelligence the way you would talk to a person, and hear it answer back, without touching a keyboard. This guide explains how it works, which assistants offer voice as of October 22, 2026, how to get good results and which settings to check to protect your privacy.

What happens when you talk to an AI

A voice assistant runs through three steps in a few seconds:

1. It listens. Speech recognition turns your voice into text.
2. It thinks. A large language model, the same kind of program that powers ChatGPT, works out what you want and writes a reply.
3. It answers. Text-to-speech reads that reply aloud, in a voice that sounds more natural every year.

The first mainstream assistants, such as Siri, unveiled by Apple on October 4, 2011, mostly recognized set commands: “set a timer”, “what’s the weather”. Today’s assistants can hold a real conversation, handle follow-up questions and keep track of what you said earlier.

Three ways to talk to an AI

Depending on the device you use, voice works in different ways.

Form	Examples	Best for	Watch out for
Chatbot voice mode	ChatGPT, Gemini, Copilot, Le Chat	Chatting, practising, thinking out loud	Usage limits on free plans
Phone assistant	Siri with Apple Intelligence, Gemini on Android	Acting in your apps, hands-free	Requires a compatible device
Smart speaker or display	Alexa+ on Echo	Home, timers, music, smart devices	A microphone in the room

You don’t have to pick just one: plenty of people dictate on their phone and keep a speaker in the kitchen.

Which assistants offer voice?

Here are the main assistants and their features, taken from the providers’ websites. The “voice” column shows whether the provider advertises voice interaction.

Assistant	Free	Paid from	Web search	Agent mode	Voice	Images
ChatGPT	Limited	$8/mo	Yes	Yes	Yes	Yes
Gemini	Limited	€4.99/mo	Yes	—	Yes	Yes
Microsoft Copilot	Limited	$9.99/mo	Yes	—	Yes	Yes
Le Chat (Mistral Vibe)	Limited	$5.99/mo	Yes	Yes	Yes	Yes
Alexa+	Limited	$19.99/mo	Yes	Yes	Yes	—
Apple Intelligence et Siri AI	Yes	—	Yes	Yes	Yes	Yes

A blank cell means the provider doesn’t say, not that the feature is missing. To compare more assistants against your own criteria, try our AI assistant comparison tool.

Two cases are worth a closer look. Alexa+, Amazon’s rebuilt Alexa based on generative AI, is available in the United States and Canada; according to the site’s profile page, it is included with Amazon Prime or costs $19.99 a month without Prime in the US, while the UK has free early access, with £19.99 a month announced for later. Siri with Apple Intelligence is included at no extra cost on compatible Apple devices, starting with the iPhone 15 Pro.

Getting started in four steps

1. Pick your starting point. If you already have an assistant’s app on your phone, start there. There’s no need to buy a speaker just to try it.
2. Allow microphone access. The first time, your phone asks for permission to use the microphone. You can withdraw it at any time in your settings.
3. Open voice mode. In the app, look for the microphone or voice mode icon. On a speaker, say the wake word.
4. Start simple. A general knowledge question, a recipe, a word to translate: you’ll quickly see how the assistant responds and how fast it answers.

How to talk to your assistant

Speaking changes the way you phrase requests a little.

• Give context first. “I’m cooking dinner for six, and one guest is vegetarian: suggest a simple menu” works better than a string of small questions.
• Feel free to interrupt. If the answer is heading the wrong way, cut in and rephrase, just as you would in a real conversation.
• Ask for short answers. A long list is hard to remember when you hear it. Say “in three points” or “in two sentences”.
• Ask it to repeat or spell. For a name, an address or a number, ask for confirmation. Speech recognition gets these wrong more often.

A few situations where voice really shines: practising a language through conversation (see our guide to learning a language with AI), asking questions on the road or while sightseeing (our tutorial on planning a trip with AI), or listening to a summary when your eyes are tired (see how to summarize a document with AI).

When typing is still better

Voice isn’t always the right choice. Stick with the keyboard in these situations:

• Text you need to keep or send. A letter, meeting notes or a long list are easier to review in writing, where you can fix every word.
• Sensitive information. In a public place or a shared office, everyone hears your question, and the answer read aloud.
• Documents to analyze. A contract, a spreadsheet or a photo is easier to handle by uploading the file into a written chat.
• Technical vocabulary. Drug names, legal terms or product references are often transcribed wrongly: type them.

Privacy: the settings to check

A voice assistant picks up the sounds of your daily life, sometimes your family’s too. Take ten minutes to go through the settings.

Three habits apply to every assistant: mute the speaker’s microphone during a sensitive conversation, clear your voice history regularly, and let guests know that a device may hear them.

Beware of cloned voices

Text-to-speech has become so realistic that it can imitate a specific person’s voice from a short recording. That opens the door to AI-powered scams: a fake call from a relative in trouble, a fake message from a bank or a boss.

Check yourself Your son calls from an unknown number in a panic: he needs money wired right away. It really sounds like him. What do you do?

You hang up and call him back on his usual number, or reach a relative who can confirm. A familiar voice no longer proves who is speaking. Agreeing on a family code word in advance is a simple, effective precaution. If it was a scam attempt, you can report it to the FTC in the US or to Action Fraud in the UK.
