Dictation Punctuation: How to Say Commas, Periods and More

You get punctuation in dictation in one of two ways. You can say the mark by name, so "comma" types a comma. Or you can let automatic punctuation insert marks from the timing and pitch of your speech. All four platforms in this guide offer both. You can switch the automatic method off on iPhone, on the Mac and in Windows, and in Word where the language allows it.

For most people the spoken method is the reliable one, and the automatic one is the convenient one. The spoken words are not the same on every platform, so this guide starts with the words you say, then covers where automatic punctuation helps and where it fails, and ends with the formatting that people struggle with: new lines, numbers, capitals and quotation marks. It is part of our overview of dictation, and for the broader picture of dictation commands, see dictation commands. The short answer to whether dictation adds marks by itself is on does voice typing add punctuation automatically.

Say the name of the mark and the software types the mark

Spoken punctuation is the method you control. On iPhone, Apple's steps say to "Say the name of the punctuation mark, such as 'exclamation point.'" ¹. The mark is typed where the cursor is. This is called spoken punctuation, and it is a kind of voice command that types a symbol instead of running an action.

The question mark uses the same spoken words on all four platforms in this guide. On the Mac, "question mark" produces "?" ². On iPhone, the Dictation command list includes "question mark" ³, Word's English table does too ⁴, and Windows lists "? question mark" in its English symbol table ⁵. The full answer, with the exact phrase to use, is on how to say a question mark when dictating.

Many marks have more than one spoken name, and you should learn the one your platform reads most reliably. On the Mac, the full stop is spoken as "period", "point", "dot" or "full stop" ². Use one name consistently in a session, so you do not have to guess which one the software will accept.

Deleting a mark is a voice command too. In Microsoft 365 Dictation, saying "delete" by itself "removes the last word or punctuation before the cursor" ⁶. Use it straight after a wrong mark, before you dictate the next sentence.

Automatic punctuation guesses periods and commas from your pauses and pitch

Automatic punctuation infers marks from the audio. Google describes its speech service this way: when the feature is on, the service "automatically infers the presence of periods, commas, and question marks in your audio data and adds them to the transcript" ⁷. Off by default, the service leaves punctuation out: "Speech-to-Text does not include punctuation marks" in its results ⁸. With the setting on, the same service capitalizes the first letter after each period and question mark ⁹. This describes Google's developer speech API, not the voice typing in Google Docs.

One research approach uses prosody, which is the rhythm and pitch of speech. A 2019 journal paper proposes "a prosody inspired approach" to punctuation in speech recognition output ¹⁰. The paper does not say that commercial dictation apps use it. Apple's Mac page says that for supported languages, Dictation "also adds certain punctuation automatically as you dictate" ¹¹, and the Mac User Guide names the marks, in supported languages: "automatically inserts commas, periods, and question marks" ¹². On iPhone the list is the same three marks, in supported languages: Dictation "automatically inserts commas, periods, and question marks as you dictate" ¹³.

Automatic punctuation is least reliable for question marks and commas

Accuracy depends on the mark. The clearest comparison comes from a 2023 chapter that reviews earlier English systems on the IWSLT 2011 benchmark, which uses TED talks. On reference text, the best reported comma F1 was 76.7% ¹⁴. On speech recognition output, it fell to 66.3% ¹⁵, a drop of 10.4 percentage points ¹⁶. On reference text, the best period F1 was 88.9% ¹⁷, and the best question mark F1 was 87.8% ¹⁸. On recognition output, periods held up best, at 82.3% ¹⁹. Question marks were the weakest on recognition output, at 63.4% ²⁰.

The chart below shows the six figures together.

Three limits apply to these numbers. They come from TED talks, not dictation. F1 combines missed marks and wrong marks into one score, so it does not tell you how many marks you will fix by hand. And each figure is the best of several earlier systems, not the average. A 2021 preprint reports a different kind of result: the best BERT models reached a macro-averaged F1 of 79.8 on English TED Talks transcripts ²¹. That single number averages across all marks, so it hides the gap between commas and periods.

The reason the errors matter is that a wrong mark is harder to ignore than a missing one. The 2019 paper argues that automatic punctuation should favor precision: "precision is more crucial in this sense than recall" ²². Its reason is that a reader should have to insert a missing mark rather than remove an incorrect one. For you, that means automatic punctuation is most useful for drafts, and spoken marks are safer for text where every comma counts.

The spoken words differ by platform, and one table shows them all

Each platform has its own list of spoken words, and the lists are not identical. The table compares the four official pages read for this guide: Apple's Mac and iPhone pages, Microsoft's Word page and Microsoft's Windows voice typing page. Microsoft's Word list is the English column. Other languages have different words, and Windows uses different words in other languages too.

Sources for the table: Commands for dictating text on Mac, Commands for dictating text on iPhone, Dictate your documents in Word and Use voice typing to talk instead of type on your PC. "Not listed" means the page read on 2026-10-16 does not give that command, not that the feature cannot exist.

Two rows matter most. The English Word list gives the question mark, comma and full stop, but it has no "new paragraph" entry ⁴. Word also offers an Auto Punctuation toggle, but only where it is available for the chosen language ²³.

Google Docs is missing from the table. The Google help page for voice typing did not open during this review, so its command list is not checked here. Check Google's own help page for the current list before you rely on it.

New line and new paragraph are separate commands on the Mac and in Windows

On the Mac and in Windows, a line break and a paragraph break are separate commands. On the Mac, "new line" starts a new line and "new paragraph" starts a new paragraph ²⁴. Windows lists "new line", "new/next line" and "new paragraph" in its English table ²⁵. On iPhone, both phrases add a line break, and the page lists them under the same step ²⁶.

Word is the exception in the English table. The list has "new line" but no "new paragraph" entry ⁴. If you dictate a letter in Word, test "new line" first and check the paragraph spacing afterward. The steps for starting a paragraph by voice are on how to start a new paragraph by voice. For a fuller list of editing commands, see Word dictation.

Numbers and symbols follow formatting commands you can steer

The simplest method for numbers is to say them. Windows voice typing says you "can dictate most numbers and punctuation by saying the number or punctuation character" ²⁷. The page says "most", not all, so check any long number before you rely on it.

On the Mac, a formatting command changes how the next phrase is written. "No space on" formats the next phrase without spaces, and "no space off" resumes the default spacing ²⁸. That is useful for a code name or a file name, where a space would be wrong. "Numeral" formats the next phrase as a number, and "roman numeral" formats it as a Roman numeral ²⁹. The Windows symbol table also lists spoken names for symbols such as "@ at sign" ⁵, so symbols you use often can be dictated the same way as punctuation.

I did not find a dictation command for dates on any of the four pages. For dates, say the words, or type the date afterward. The steps for numbers, with examples, are on how to dictate numbers.

Capitals and quotation marks have their own commands

Capitalization is a formatting command, not a punctuation mark, and the platforms do not agree on the words. Spelling is the related problem: a name or a code that the software does not know. On iPhone, Apple's example is to "Say something like 'Let's invite Steven S-T-E-P-H-E-N'" ³⁰, so you spell the word letter by letter. Use spelling for a name that you cannot get right by voice, and read how to make dictation spell names correctly for the wider fix. On the Mac, "caps on" formats the next phrase in Title Case, and "caps off" returns to the normal lettering ³¹. Title Case capitalizes the main words of a phrase, so it suits headings and not ordinary sentences. On the Mac, "all caps" formats the next word in capitals ³².

On iPhone, "Cap" capitalizes the next word, and "caps on … caps off" capitalizes the first character of each word in the enclosed words ³³. On Windows, you say "uppercase" before a letter to dictate a capital letter ³⁴. The Word list uses "capitalize" followed by a word or phrase, which is listed on the page but was not fact-checked for this guide. Read how to capitalize a word by voice for the steps on each platform.

Quotation marks have two parts: an opening and a closing command. On the Mac, "quote" opens a quotation and "end quote" closes it ². Word and Windows use "open quotes" and "close quotes" in their tables. The Word and Windows pages are the sources for those phrases, shown in the table above.

Spoken and automatic punctuation can overlap, and the pages do not say how

The four pages read for this guide describe the two methods separately. None of them says what happens when you say a mark and automatic punctuation also inserts one. You should test this in the app you use. Dictate a sentence with "comma" in it and read the result. If you always say your marks, turn automatic punctuation off. On iPhone, that is Settings > General > Keyboard, then turn off Auto-Punctuation ³⁵. In Word, it is the Auto Punctuation toggle, where the language allows it ²³. In Windows, it is the Automatic punctuation setting ³⁶. Apple's Mac command page does not describe a switch for its automatic marks. Apple's Mac User Guide says to turn that feature off by choosing Apple menu > System Settings, then clicking Keyboard in the sidebar ¹².

Windows also has a feature that goes beyond punctuation. Fluid dictation on Copilot+ PCs "automatically corrects grammar, punctuation, and filler words as you speak" ³⁷. The page says it works in English locales, and you can undo a correction by saying "Revert" or "Undo that".

The 2019 paper describes the design of dictation systems in its introduction. It says that a "telegraphic style alike explicit dictation of the punctuation marks was foreseen" ³⁸. If you rely on spoken marks, automatic insertion is the part to switch off.

A short routine settles the question for your own app in a few minutes:

1. Open a new note or document and dictate one sentence that includes a comma, a period and a question mark, all spoken.
2. Read the result. Note any mark you did not say that appeared, and any mark you said that did not.
3. Turn automatic punctuation off in the app's settings, dictate the same sentence again, and compare the two results.
4. Keep the setting that gives you the fewest marks to fix, for the kind of writing you do.

Spoken corrections can be misheard, so fix a stray mark by keyboard

Correcting a mistake by speaking again can backfire. In a 2006 study on a simulated dictation interface, spoken corrections were often misrecognized too, which cost users time ³⁹. A misplaced comma is a small error, so it is usually simpler to fix it with the keyboard than to say a correction and hope it is heard.

I found no study that times punctuation fixes on their own, so the advice here is practical rather than measured. Dictate the words, use the spoken marks you need for formal text, and fix a leftover comma with a key press. For the wider habit of drafting by voice and editing afterward, see how to dictate and dictation mistakes.

What to do next

1. Learn the spoken names your platform uses from the table above. Test the marks you use most.
2. Use spoken marks for formal text. Use automatic punctuation for drafts, and check the commas.
3. In Word, test "new line" before relying on "new paragraph".
4. Fix leftovers with the keyboard, not with another spoken correction.

Built-in tools are enough for most of this. The Mac, iPhone, Windows and Word pages cover the commands above, and the platform guides list the rest: Mac dictation commands, Windows voice typing commands and Google Docs voice typing. To try dictation without installing anything, use online dictation.

Yap, which we make, is an on-device dictation app for Mac and Windows. This guide does not check its command list, so if you compare apps, check each app's own command list against the table above before you choose. You can find the app on the download page.
