About Pulse Keyword Identification
The Pulse engine can identify specific keywords spoken within videos. It does not identify all words in
a video. Instead, your system administrator provides and maintains a list of keywords on the Cisco MXE.
The Pulse engine scans the video for those keywords and places markers in the video timeline where they
appear. When you select a keyword from the list, all instances of that keyword appear as markers in the
timeline. You can jump to a specific marker or navigate forward and backwards through them.
The black triangle marks in the video timeline, below, mark each instance of the keyword “videos” in
the video.
Additionally, these keywords are included when filtering video lists or searching for videos with
keywords.
The Pulse keyword identification feature only identifies English keywords. Additionally, the accuracy
of keyword identification depends upon the quality of the recorded audio and whether or not there is a
lot of background noise in the audio track.
