Speaker Recognition and Timestamps: Professional Transcript Preparation — memozero

Automatic Speaker Recognition

memozero automatically identifies different speakers in your recording and assigns each a unique label (e.g., “Speaker A”, “Speaker B”). This assignment is powered by the locally executed diarization engine pyannote.audio.

Renaming Speakers

In practice, you’ll want to replace generic labels with real names or roles. The Global Rename feature lets you change a speaker label in one place — and it updates automatically throughout the entire document. “Speaker A” becomes “Witness” or “Dr. Smith” in seconds.

Word-Level Timestamps

Every recognized word receives an exact timestamp. This enables:

• Citable references: Provide the exact audio position in reports or protocols.
• Synchronized playback: During audio playback, the currently spoken word is highlighted karaoke-style in the text.
• Quick navigation: Click any word to jump directly to the corresponding position in the recording.
