Audio Speaker Identification Annotation -- 2

I need help turning a batch of raw recordings into clean, speaker-labelled data. Every file already carries basic metadata; what is missing is precise speaker identification. Your task is to listen through each track, mark the start- and end-times whenever a new voice begins, and assign a consistent speaker ID throughout the set.

Please deliver:
• A time-stamped annotation file for each recording (CSV or JSON) that lists segment start, segment end, and assigned speaker label.
• The annotated audio back in its original folder structure so it stays aligned with our internal pipeline.

Accuracy matters more than speed, so feel free to use diarization tools such as pyannote.audio, SpeechBrain, or your own proprietary workflow—just document what you use so we can reproduce results later.

When you reply, point me to past work that shows you have handled speaker identification before; a short paragraph and one or two sample links are enough.
