Dump voice vectors and enable diarization only.

Great addition with the diarization! :-)
We use diarization as a separate independant step in a complex workflow using FFAStrans. But it would be nice to do it without the extra separate pyannote package now that you have implemented it in faster-whisper-xxl. So in that regard I have two feature requests

1. Fetch speaker embeddings (if available?) and dump. Speaker Diarization #322 (reply in thread)
2. Make it possible to only do diarization without transcribing.

Keep up the great work! :-)

Please add the ability to diarize by saving the file --diarize_dump but without running transcribing. Now I have to wait for transcribing to finish although I only need the txt file of the dump.

Also from txt dump, with the help of PowerShell script written by ChatGPT, I get srt file with SPEAKER_01, SPEAKER_02, etc. as text.
It would be great if you could do such output in srt in Faster-Whisper-XXL directly without using external scripts.

Then I work with this file in SubtitleEdit and leave only subtitles for the desired speaker in the bilingual video. After that I use another PowerShell script and mute other speakers in the video and transcribe the result as usual. In this way I get transcription of bilingual video of acceptable quality.

Script diarize_dump2srt:

# Input file path
$inputFile = “video.mp4_diarize_pyannote_v3.1_dump.txt”
# Path to output file
$outputFile = “output.srt”

# Read lines from the file
$content = Get-Content $inputFile

# Initialize subtitle counter
$counter = 1

# Create or clear the output file
Out-File -FilePath $outputFile -Encoding utf8

foreach ($line in $content) {
# Extract start time, end time and text
if ($line -match '\[\s*(\d{2}:\d{2}:\d{2}\.\d{3})\s*-->\s*(\d{2}:\d{2}:\d{2}\.\d{3})\]\s*\w+\s*(SPEAKER_\d+)') {
$startTime = $matches[1]
$endTime = $matches[2]
$text = $matches[3]

# Subtitle generation
$srtEntry = @”
$counter
$startTime --> $endTime
$text

“@
# Write subtitle to file
Add-Content -Path $outputFile -Value $srtEntry

# Increase subtitle counter
$counter++
}
}

Write-Host “Conversion completed. The file is saved as $outputFile”
