Locate child segments marked as CRY

CRY segments can be located several ways:

Search the exported TRS file

  • This article provides basic information on doing a manual search in the .trs file.
  • See the trs2seg article for information on using this executable file to export segment and CRY information from LENA's TRS file.

Pull directly from the exported ITS file

  • ADEX does not currently pull CRY information, but CRY is clearly labeled and can be obtained directly from the .its file.
  • Users with programming knowledge may write a script to pull CRY onset and offset times directly from the .its file.

Use ADEX to create a summary of all NonVOC segments (where CRY may occur)

  • This summary can be a starting point for locating CRY segments in LENA.

1. Manual search for CRY in the .trs file.

1.1. Export a TRS for the recording (must have audio available).

Full instructions for exporting the TRS are here.

1.2. Open the .trs file in Transcriber software.

Open the .trs file in Transcriber software.

1.3. Ctrl+F (or Edit/Find) to find each instance of CRY.

From here you can see the segment duration, see the segment onset and offset, and/or listen to the segment.

2. Obtain onset and offset times for CRY directly from the exported ITS file.

A manual search for StartCry will take you to each onset, noted in seconds.

In this example, the CRY portion of the segment starts at 46914.52 seconds into the recording.

The CRY portion ends at 46915.52 seconds, as noted by endCry.

The duration is 1 second (childCryVfxLen).

A manual search for StartCry will take you to each onset, noted in seconds.

Users with programming knowledge may wish to write a script to pull CRY onset and offset times.

3. ADEX can be used to create a summary of all NonVoc segments (where CRY may occur).

This summary can be a starting point for further investigation.

3.1. In ADEX choose Output Row Resolution = Vocalization Activity Block, and check the box for Segment Details.

3.2. Select the following Output Columns:

  • CHN (segment duration)
  • Child_Voc_Duration (optional, for reference only)
  • Child_NonVoc_Duration (portion of the CHN segment that is neither speech-related nor interstitial silence)
  • FUZ (may contain some CHF-NonVoc segments)
  • Elapsed_Time
  • Clock_Time (optional, if you wish to look at a certain time of day, e.g., around feeding time)
  • Segment_Duration
  • Speaker_ID (helpful for filtering CHN/CHF if desired)
Select the following Output Columns:

3.3. In your export program of choice (Excel, SPSS, etc), filter to show only rows with Child_NonVoc_Duration >0 seconds.

The Elapsed Time column now serves as a summary of areas to investigate in the .trs file.
