Expectations
Screen Reader support by expectation
| Expectation | JAWS | Narrator | NVDA | Orca | TalkBack | VoiceOver (iOS) | VoiceOver (macOS) | ||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Chrome | Edge | Firefox | Edge | Chrome | Edge | Firefox | Firefox | Chrome | Safari | Safari | |
| MUST convey the `inline` value | none | none | none | none | partial | partial | partial | none | none | none | none |
| MUST convey the `list` value | none | none | none | none | partial | partial | partial | none | none | none | partial (1/2) |
| MUST convey the `both` value | none | none | none | none | partial | partial | partial | none | none | none | none |
| MUST convey the `none` value | supported | supported | supported | supported | supported | supported | none | supported | supported | supported | supported |
Expectation: convey the `inline` value
Rationale:
Screen reader users need to be aware that a form control has inline autocomplete behavior before they start typing so that the behavior is not unexpected.
Strength of this expectation for different types of assistive technologies:
- Screen Readers: MUST
- Voice Control: NA
| Test | JAWS | Narrator | NVDA | Orca | TalkBack | VoiceOver (iOS) | VoiceOver (macOS) | ||||
|---|---|---|---|---|---|---|---|---|---|---|---|

| aria-autocomplete reduced test case applied to: input[type="text"] element | none | none | none | none | partial | partial | partial | none | none | none | none |
Expectation: convey the `list` value
Rationale:
Screen reader users need to be aware that a form control has list autocomplete behavior before they start typing so that the behavior is not unexpected. When used on a combobox, this value should hint to users that the popup contains auto complete suggestions rather than a static set of options.
Strength of this expectation for different types of assistive technologies:
- Screen Readers: MUST
- Voice Control: NA

Expectation: convey the `both` value
Rationale:
Screen reader users need to be aware that a form control has both inline and list autocomplete behavior before they start typing so that the behavior is not unexpected. When used on a combobox, this value should hint to users that the popup contains auto complete suggestions rather than a static set of options.
Strength of this expectation for different types of assistive technologies:
- Screen Readers: MUST
- Voice Control: NA
Expectation: convey the `none` value
Rationale:
Screen reader users should not be informed that auto complete behavior exists when the behavior does not exist.
Strength of this expectation for different types of assistive technologies:
- Screen Readers: MUST
- Voice Control: NA
Examples:
- Screen readers will omit any announcements about autocomplete behavior.
