# timestamp

The start time of the segment in the processed audio stream.

## Declaration

```swift
var timestamp: TimeInterval { get }
```

## Discussion

Discussion The timestamp is the number of seconds between the beginning of the audio content and when the user spoke the word represented by the segment. For example, if the user said the word “time” one second into the transcription “What time is it”, the timestamp would be equal to 1.0.
