Accessibility Label Not Punctuated

Accessibility labels on iOS elements should end with appropriate punctuation so VoiceOver produces natural pauses and intonation when reading them.

WCAG Reference

Maps to: WCAG 3.3.2 Labels or Instructions | Applies to: WCAG 2.0, WCAG 2.1, WCAG 2.2 Introduced in: WCAG 2.0 | Level: A | Read the official specification →

What this rule checks​

The scanner flags accessibility labels that do not end with proper punctuation (period, comma, question mark, or exclamation mark), which affects VoiceOver's speech cadence and clarity.

Why it matters​

VoiceOver uses punctuation to determine pacing and intonation. A label that ends abruptly without punctuation causes VoiceOver to run the label into the next announcement without a pause, making it harder for users to parse individual elements.

Common failure patterns​

  • labels like "Add to cart" with no trailing period
  • descriptive labels on images that read as sentences but lack ending punctuation
  • multi-word labels that describe status or state without punctuation

Remediation guidance​

  • end accessibility labels with a period when they form a complete phrase or sentence
  • use punctuation consistent with the label's tone: period for statements, question mark for questions
  • keep labels concise: a label should describe the element, not be a paragraph
  • test with VoiceOver to confirm the speech rhythm sounds natural between consecutive elements
