case.dev Transcription

Audio and video transcription with speaker diarization, ideal for depositions, hearings, and recorded proceedings. Supports MP3, WAV, M4A, FLAC, OGG, WEBM, and MP4 up to 5GB.

Requires the casedev CLI. See setup skill for installation and auth.

Start a Transcription

The source file must be in a vault:

casedev transcribe run --vault VAULT_ID --object OBJECT_ID --json

The object must be an audio or video file. Non-media files are rejected.

Flags:

--speaker-labels — enable speaker diarization
--speakers-expected N — hint for number of speakers
--language — language code (e.g., en, es)
--format — output format
--auto-highlights — extract key phrases

Uses focused vault if set via casedev focus set --vault.

Check Status

casedev transcribe status TRANSCRIPTION_ID --json

Returns: ID, status, vault, source/result object IDs, audio duration, word count, confidence.

Statuses: queued -> processing -> completed or failed.

Get Result

casedev transcribe result TRANSCRIPTION_ID --json

Returns the transcript text. If the result is stored as a vault object, it fetches the text automatically. Fails if the job is not yet completed.

Watch Until Complete

casedev transcribe watch TRANSCRIPTION_ID --json

Polls until done, then prints the result. Flags:

--interval / -i — poll interval in seconds (default: 3)
--timeout / -t — max wait in seconds (default: 900)

Common Workflow

Transcribe a deposition recording

# 1. Upload to vault
casedev vault object upload ./deposition-2024-01-15.mp3 --vault VAULT_ID --json

# 2. Start transcription with speaker labels
casedev transcribe run --vault VAULT_ID --object OBJECT_ID --speaker-labels --speakers-expected 4 --json

# 3. Watch until complete
casedev transcribe watch TRANSCRIPTION_ID --json

# 4. Or check status + get result separately
casedev transcribe status TRANSCRIPTION_ID --json
casedev transcribe result TRANSCRIPTION_ID --json

Using the job tracker

# Transcription jobs are auto-tracked
casedev jobs list --type transcribe --json
casedev jobs watch JOB_ID --type transcribe --json

Troubleshooting

"Invalid file type for transcribe": Only audio/video MIME types are accepted. Check the object with casedev vault object list --vault VAULT_ID. Upload audio files, not PDFs.

"Invalid object ID for this vault": Run casedev vault object list --vault VAULT_ID to see valid IDs.

"Transcription is not complete yet": Wait for the job to finish. Use casedev transcribe watch or casedev jobs watch.

Transcription failed: Check casedev transcribe status TRANSCRIPTION_ID --json for the error message. Common causes: corrupted file, unsupported codec, file too large.

Long audio (2+ hours): Increase timeout with --timeout 3600. Large files take proportionally longer.
