Dictate text on iPhone
With Dictation on iPhone, you can dictate text anywhere you can type it. You can also use typing and Dictation together—the keyboard stays open during Dictation so you can easily switch between voice and touch to enter text. For example, you can select text with touch and replace it with your voice.
Dictation requests are processed on your device in many languages—no internet connection is required. When dictating in a search box, dictated text may be sent to the search provider in order to process the search.
Note: Dictation may not be available in all languages or in all countries or regions, and features may vary.
When using Dictation, cellular data charges may apply. See View or change cellular data settings on iPhone.

Dictate text

Tap in the text field to place the insertion point where you want to begin dictating text.
Tap
on the onscreen keyboard (or in any text field where it appears).
When

To insert an emoji or a punctuation mark, or perform simple formatting tasks, do any of the following:
Say the name of an emoji, such as “heart emoji” or “smiley face emoji.”
Say the name of the punctuation mark, such as “exclamation point.”
Note: In supported languages, Dictation automatically inserts commas, periods, and question marks as you dictate. To turn off automatic punctuation, go to Settings

Say a formatting command such as “new line” or “new paragraph.”
When you’re done, tap
