Enable Pulse Spoken Keyword and Speaker Identification
March 2015
About the Pulse Video Analytics Feature
The Pulse video analytics feature set provides spoken keyword and speaker identification for videos that are transcoded by the Cisco MXE 3500. Keywords are matched to a white list that is configured by the administrator on the Pulse video analytics engine. Speaker identification is a learned process. The Pulse video analytics engine learns to identify different speakers in a video. If the speaker has been identified previously, speaker identification is entered automatically. If the speaker has not been identified, a generic speaker tag is assigned to the speaker. Authors can then use the Cisco Show and Share video editor to identify the speaker. Subsequent videos uploaded with that speaker will show the speaker name. Keyword and speaker information appear on a new tab, called Pulse, on the video player window.
Guidelines and Limitations
- Videos recorded directly in Cisco Show and Share are not transcoded unless the Pulse video analytics features are enabled. If the Pulse video analytics features are not enabled, recorded videos will not be transcoded and therefore will not be available to mobile clients or have any Pulse video analytics information associated with them.
- Windows media that has bypassed transcoding will not contain the Pulse video analytics features.
- Existing videos published in an earlier version of Cisco Show and Share will not have the Pulse video analytics features unless they are re-uploaded and transcoded.
- Existing videos published before the Pulse video analytics feature set was enabled will not have the Pulse video analytics features unless they are re-uploaded and transcoded.

Disable Pulse Video Analytics Features
Any videos that are uploaded after disabling the Pulse video analytics features will not be processed by the Pulse video analytics engine. They will need to be re-uploaded in the future. Disabling Pulse video analytics features prevents videos that are recorded directly in the Cisco Show and Share interface from being transcoded. Therefore, videos that are recorded while the Pulse video analytics features are disabled will not be viewable in the mobile client.

Step 3
To disable the feature, clear the check box under Pulse Spoken Keyword and Speaker Recognition in the Settings area.
Re-Upload a Published Video
For a video that was published before the enabling Pulse, you must re-upload the video to apply the Pulse analytics features. Re-uploading the video sends the file to the Cisco MXE 3500 for transcoding.
