Fearless Steps Challenge:
Phase II

Topic Detection

Identifying salient events in a continuous audio stream is important. Its significance is even more for time-critical events such as the Apollo Missions. Identification of ‘hotspots’ in over 150,000 hours can help both STEM and non-STEM researchers in analysing high value content. We define the following critical events as ‘hotspots’

• Alarms
• Loss of Signal
• Acquisition of Signal
• mission critical status checks
• mission landings (earth-reentry and lunar)
• mission liftoffs (earth and lunar)
• Team switch
• Checkpoints

These hotspots are defined a conversational context. All mission control speech segments with the above mentioned events as primary topics of discussion between personnel are considered for this task.
