macOS Feature Availability, Apple, Apple, 2026, Dictation: Auto-Punctuation (feature table).

What it measures: Checked on 2026-10-17 on the same Apple page. Auto-Punctuation adds commas, periods and question marks as you dictate, in the languages the page lists.
What it does not show: This is the list on the page checked on 2026-10-17, not a guarantee for every macOS version. The absence of Chile means the page does not list it, not that the feature fails there.
