Speech to text on iPhone: how to turn on dictation and dictate in any app

Your iPhone can already write while you talk, with nothing to install. Speech to text on iPhone lives inside the iOS keyboard: a microphone icon, a few spoken words, and the text lands in whatever app you're in. This guide covers how to turn on dictation on iPhone in thirty seconds, how to dictate a message, an email or a note, how punctuation and offline mode work, what to do when the microphone vanishes from your keyboard, and when an AI dictation app is genuinely worth it.

Two ways to dictate on iPhone

Before choosing, it helps to separate two tools that share a name but don't do the same job:

• Apple's built-in dictation. Free, already in the keyboard, often processed directly on the device. It transcribes what you say, word for word, and adds basic punctuation. Perfect for a short message.
• AI dictation apps (like Fast Dictate). They add a layer of artificial intelligence: fillers removed, punctuation and grammar handled, text formatted. You get a paragraph that's ready to send, not a draft to fix with your thumbs.

Let's start with the one already in your pocket.

How to turn on dictation on iPhone

iOS dictation is enabled once, in Settings. Per Apple's official iPhone User Guide:

1. Open Settings, then General, then Keyboard.
2. Scroll to the Dictation section and turn on Enable Dictation.
3. Open any app where you write (Messages, Mail, Notes) and tap a text field to bring up the keyboard.
4. Tap the microphone icon 🎤 at the bottom of the keyboard: bottom right on Face ID iPhones, to the left of the space bar on Home button models.
5. Speak naturally. The text appears as you talk. Tap the microphone again to stop, or just pause: dictation ends on its own after about 30 seconds of silence.

One detail that matters in practice: the keyboard stays on screen while you dictate. You can go back and forth between voice and typing without breaking stride, dictate a sentence, fix a word by hand, then carry on speaking. That's what makes iOS dictation comfortable for everyday messages.

Dictating a message, an email or a note: the same gesture everywhere

Voice to text on iPhone belongs to the keyboard, not the app. The gesture is therefore identical anywhere a keyboard appears: Messages, Mail, Notes, WhatsApp, Safari, Word, Slack, LinkedIn or any search field. To dictate a text message on iPhone:

1. Open the conversation and tap the message field.
2. Tap the microphone on the keyboard and dictate your message.
3. Read it back, fix anything if needed, then send.

For fully hands-free use there's another route: ask Siri to send the message for you (“Hey Siri, send a message to Marie”). Siri takes the dictation, reads the message back and sends it on confirmation. Handy in the car, less precise for anything long or polished.

Punctuation, emoji and voice commands

This one is widely misunderstood: since iOS 16, Apple's dictation adds punctuation automatically (commas, periods, question marks) in supported languages. You no longer have to say “period” at the end of every sentence, contrary to what a lot of older articles still claim.

You keep control when you want a specific character. Apple documents a list of commands for dictating text:

• Say “period”, “comma”, “question mark” or “colon” to force punctuation.
• Say “new line” or “new paragraph” to structure a longer text.
• Apple also documents commands for emoji and formatting, plus “stop dictation” to finish by voice.

In practice, automatic punctuation does well on short, clean sentences. On a paragraph dictated in one go, with hesitations and mid-sentence changes of mind, it rarely breaks the text up the way you would have written it.

Does iPhone dictation work offline?

Often, yes. Apple states that dictation requests are processed on the device in many languages, with no internet connection required. That's a real advantage of the iOS ecosystem: on a plane or with no signal, dictation keeps working.

The nuance matters for professional use. According to Apple's Siri and Dictation privacy notice, your device indicates in Keyboard Settings whether your audio and transcripts are processed on the device and not sent to Apple's servers. Otherwise, what you dictate is sent to and processed on Apple's servers, where it isn't stored unless you opted in to help improve Siri and Dictation. To understand what really separates on-device recognition from cloud processing, see our local vs cloud voice dictation comparison.

Changing the dictation language

On iPhone, dictation follows the language of the active keyboard. To dictate in French or German, add the matching keyboard:

1. Go to Settings › General › Keyboard › Keyboards › Add New Keyboard and pick the language you want.
2. In any app, press and hold the globe key 🌐 to switch languages, then tap the microphone.

Worth knowing if you're bilingual or work internationally: Apple's dictation doesn't switch languages by itself mid-sentence. Every switch costs you a gesture.

iPhone dictation not working, or the microphone is gone: the usual causes

This is the most common follow-up question. In the vast majority of cases, one of these four explains it:

If you keep hitting the microphone by accident and would rather remove it from the keyboard, it's the same path in reverse:

1. Open Settings › General › Keyboard.
2. Turn off Enable Dictation and confirm.
3. The microphone icon disappears from the keyboard in every app. You can switch it back on anytime the same way.

The limits of built-in iOS dictation

Apple's dictation is fast, free and privacy-friendly when it runs on the device. Its limits show as soon as the text gets longer or has to be polished:

For a text message, none of this costs you anything. For a client email, a report or a message that has to be flawless, you end up correcting with your thumbs, which cancels out part of the time saved. That's exactly where AI dictation changes the equation.

Fast Dictate: AI dictation on iPhone

Fast Dictate is a dictation app that adds a layer of artificial intelligence between your voice and the text. On iPhone it takes the form of a Fast Dictate keyboard that you add to iOS, so you can dictate in any app, right where you already write.

Setup, in three steps:

1. Install Fast Dictate from the App Store and create your free account.
2. Open Settings › General › Keyboard › Keyboards › Add New Keyboard and choose Fast Dictate.
3. Tap Fast Dictate in the list and turn on Allow Full Access. That setting is what lets the keyboard share the dictated text with the app. The keyboard never reads or logs your keystrokes and has no network access of its own: the microphone is only used when you explicitly ask for it.

Then, in any app: tap the globe key 🌐 to switch to the Fast Dictate keyboard, tap the Fast Dictate button, speak, and confirm with ✓. The clean text is inserted in the field you were in. On the first dictation the app opens for a second to start the microphone, then you swipe back to your app: iOS does not allow a keyboard extension to record audio itself, so this step is imposed by Apple. Follow-up dictations start straight from the keyboard.

The difference is in what happens between your voice and the text. The AI:

• automatically removes hesitations, repeats and false starts;
• adds punctuation and splits sentences based on meaning, not on voice commands;
• corrects spelling and grammar;
• structures the text into paragraphs or lists based on your intent.

The result: you write 3 to 5 times faster than typing, with text that's ready to send rather than a draft. The same account and the same AI work on iPhone, Android, Mac and Windows, with more than 130 languages supported.

Where does your voice go?

When it comes to the dictation keyboard itself, several apps look alike. Wispr Flow, the leading US app, also offers an AI dictation keyboard on iPhone. So the real question for a European user isn't “how does it work”, but where your voice goes.

Any AI dictation involves cloud processing: that's the price of having a language model rewrite your text, and it's the clear difference with Apple's on-device dictation. Most of these services process your audio on servers located in the United States. Data hosted across the Atlantic can fall under the US CLOUD Act, a genuine point of caution as soon as you dictate professional or confidential information.

This is where Fast Dictate stands apart. The Standard Plan already gives you fast, GDPR-compliant AI transcription. With the Pro Plan, your voice is processed on ISO 27001-certified servers located in France, with zero data retention, for the professions where residency genuinely matters: lawyers, accountants, HR, management. For more, see voice dictation and GDPR and our Wispr Flow alternative guide.

Apple Dictation vs Fast Dictate on iPhone

Apple wins on price and offline use; AI dictation wins on the quality of the text you get, and with the Pro Plan on having your data processed in France.

When Apple's dictation is enough

Let's be straight about it: built-in iOS dictation already covers a lot of needs, and it costs nothing. Stay with it if:

• you mostly dictate short messages, where two words to fix change nothing;
• you need to dictate without a connection, on a plane or with no signal;
• you want nothing to leave the device, which Apple's dictation allows in many languages.

Speaking is faster than typing for almost everyone, roughly three times faster according to a 2016 Stanford study. AI dictation starts paying off when you write longer texts from your phone, when the result has to be presentable with no editing, or when the confidentiality of your professional dictations means you need to know exactly which country processes them. That's typically the case for lawyers and legal teams, or for work emails dictated between two meetings.
