Hi Kelsey,

In Video Labeler App, it is only possible to label image frames/sequences and you will not be able to access the audio in the videos. To work with the audios, you must use the Audio Labeler App which is also available in the MATLAB Apps tab under the Signal Processing and Communications.

You can select load Audio files option to load audio files as well as video files and it will automatically extract the audio in case of video files to work with.

Refer to the documentation to learn more about the Audio Labeler App:

Hope it is helpful.
