Introduction to clipping audios, file naming and usual order of administration

 

This section provides guidance for Research Assistants on clipping Connected Speech task audios, including file naming and the standard order of task administration. The same task and clipping order applies across all languages unless otherwise noted by the clinician in the last comment column of the Smartsheet.

Before April 2024 and participant BISE013 all participants were video clipped. Now we only clip audios and in specific cases we clip videos, please refer to video clipping guide: 2.2 Clipping VIDEOS Using Quicktime Player

Clipping and reclipping should always be completed in the lab. If you must work remotely, it’s essential to follow these steps since we are handling patient data:

  • Connect through the UT VPN

  • Work in a private, secure location

  • Use headphones to protect audio confidentiality

  • Delete all audios and videos from the computers and Trash before finishing your shift

The usual task orders are organized by:

  • Set 1 + 3

  • Set 2 + 3

  • Mid-treatment (Clinical Trial/Therapy only)

  • EB1/EB2 (Non-R01 participants only)

Important:
Per Decision 20241003, always prioritize clipping Pre, Post, and Follow-up sessions. Mid-treatment sessions should be clipped only if specified for a research need or if all other samples are clipped. This structure ensures consistency, clarity, and efficient data handling across all projects.
