Meeting speaker diarization & speaker analysis: complete guide
Speaker analysis turns a meeting recording into a structured profile of who spoke, how much, how, and with what impact. It's the foundation of any serious people analytics on meeting behaviour.
What speaker analysis is
Automatic analysis of meeting participation: distinguishes speakers, measures talk time and turns, qualifies how each one communicates.
What diarisation is
Foundational step: splits audio into segments per voice, labelling "Speaker 1, 2, 3..." even without knowing names. Once labelled, speakers can be mapped to real names.
Typical per-speaker metrics
- Total and percentage talk time
- Number of interventions
- Average intervention length
- Average sentiment
- Main topics covered
- Interruptions given and received
- Dominance index
Meeting speaker analysis: the practical guide
What speaker analysis is
Speaker analysis is the set of techniques that, starting from a meeting transcript, produces a structured profile per participant: talk time, communication style, sentiment, topics, dominance.
Diarisation: step one
Speaker diarisation is the automatic process that splits audio into per-voice segments: "Speaker 1 talks 0:00–0:42, Speaker 2 talks 0:42–1:18..." even without knowing who they are. Once labelled, speakers can be mapped to real names.
Without diarisation, any per-person metric is impossible.
Extractable metrics
- Talk time: In seconds and as a % of the total meeting.
- Number of turns: How often each one took the floor.
- Average length: Short and frequent vs long and rare interventions.
- Sentiment: Average tone per speaker.
- Topics: What each one spoke about.
- Interruptions: Who interrupts whom.
- Dominance: Composite index of time + interruptions.
Use cases
- •Leadership coaching: is the manager speaking 80% of the time? Worth knowing.
- •Team balance: measure actual participation.
- •Sales: customer call analysis, talk-to-listen ratio.
- •HR: participation patterns in team meetings.
- •Recruiting: dynamics of group interviews.
