Labeling speakers in Reduct

Reduct has a very advanced speaker identification and labeling system. It identifies speakers by the sound of a voice.

When you upload a recording into a fresh project, each paragraph is labeled as Unnamed Speaker.

You can name a speaker a handful of times, and the system picks up the same voice through the rest of the clip and across other recordings in that project, and automatically labels it.

If the same speaker turns up in another video in the project, whether it is already there or you add it next week, Reduct identifies them without you naming them again.

How to label a speaker in Reduct

  1. Click the Unnamed speaker label on a paragraph.
  2. Type the speaker's name.
  3. Press Enter.
đź’ˇ Pro tip
Label every voice you want named. In a four-person interrogation clip, label all four the first few times each one speaks. The rest of the recording will have that label applied automatically.

What happens after you label a paragraph?

  1. The label is applied wherever that voice appears: A label that Reduct automatically added shows a sparkle icon to the left.
  1. Recognition carries forward to future uploads: If the same speaker turns up in another video in the project, whether it is already there or you upload it next week, Reduct adds labels automatically without you doing it again.

Troubleshooting

A speaker you already labeled shows up as Unnamed speaker

Click the label and set the name yourself. Reduct treats that correction as a trusted sample of the voice, which makes detection on the next recording more accurate.

A label keeps landing on the wrong person

Reduct stores the voice samples for each speaker you name and uses the sample to match against the rest of the recordings. If it’s constantly detecting a wrong person, you may need to check the voice sample for that particular speaker.

  1. Click Speakers.
  2. Click the speaker whose voice you want to hear.

Play each snippet. If a snippet is someone else's voice, click Remove from trusted list.

Final tips:

  • Label each person the first few times you hear them, wherever they come up in the recording.
  • Muffled or overlapping stretches are the weakest samples. If labels are drifting, open the voice samples list and remove cross-talk and muffled snippets.
  • If a paragraph is still labeled as the wrong person after you have cleaned up the voice samples, email support@reduct.video and we'll help you out.
