Intonation
A rising-falling intonation indicates that the speaker thinks his or her statement is correct and will be confirmed by the listener, regardless of whether the tag is positive or negative.
Examples:
- Alice lives in Taipei, doesn't she?
- Alice doesn't live in Taipei, does she?
A rising intonation indicates that the speaker is unsure of his or her statement.
Examples:
- Alice lives in Taipei, doesn't she?
- Alice doesn't live in Taipei, does she?
