ISpeechRecoResultTimes OffsetFromStart Property (SAPI 5.4)

Microsoft Speech API 5.4

Interface: ISpeechRecoResultTimes

OffsetFromStart Property

The OffsetFromStart property returns the time from the start of the stream to the start of the phrase.

It is specified in 100 nanosecond units.


Set: (This property is read-only)
Get: Variant = ISpeechRecoResultTimes.OffsetFromStart


  • ISpeechRecoResultTimes
    The owning object.
  • Variant
    Set: (This property is read-only)
    Get: A Variant type containing time offset from the start of the stream.


When a recognition occurs with a valid RecoResult, the times can be extracted in order to select data at a later time. For example, using the phrase "variety is the spice of life," the OffsetFromStart position could be 21120 if the user started speaking relatively quickly once the stream began.


Use of the ISpeechRecoResultTimes object is demonstrated in a code example at the end of this section.
