+If speaker identification or differentiate is enabled, then even if you have already received `Transcribed` results, the service is still evaluating them by accumulated audio information. If the service finds that any previous result was assigned an incorrect `UserId`, then a nearly identical `Transcribed` result will be sent again, where only the `UserId` and `UtteranceId` are different. Since the `UtteranceId` format is `{index}_{UserId}_{Offset}`, when you receive a `Transcribed` result, you could use `UtteranceId` to determine if the current `Transcribed` result is going to correct a previous one. Your client or UI logic could decide behaviors, like overwriting previous output, or to ignore the latest result.
