Speaker Identification: How Speak AI Recognizes Speakers
How it works
When you transcribe audio or video with multiple people talking, Speak AI automatically detects and separates different speakers. Each speaker is labeled (Speaker 1, Speaker 2, etc.) and their dialogue is organized by paragraph.
Accuracy
Speaker identification works best when:
Speakers have distinct voices
People talk one at a time (minimal overlap)
Audio quality is good with clear separation
Each speaker uses a dedicated microphone
In noisy environments or recordings with lots of crosstalk, speaker detection may occasionally merge or split speakers incorrectly.
Renaming speakers
After transcription, you can rename speakers to their real names:
Click on any speaker label in the transcript
Type the person's name
Press Enter
The name applies to every instance of that speaker throughout the transcript. You can also use AI Chat: "Change Speaker 1 to John Smith".
For more details on managing speakers, see our speaker editing guide.
Speaker analytics
Once speakers are identified, Speak AI tracks:
Speaking time per person
Word count per speaker
Words per minute (speaking pace)
Percentage of conversation
These analytics are visible on the media detail page and can be analyzed across multiple files on the Explore page.
