Use case
Deposition transcription, ready for case prep
BrassTranscripts Legal transcribes deposition audio and video with automatic speaker identification — attorneys, witnesses, and interpreters labeled distinctly — and feeds straight into AI prompts for contradiction analysis, timeline construction, and cross-examination preparation.
Create an accountFrom recording to working-copy transcript in minutes
BrassTranscripts Legal processes deposition recordings at 1–3 minutes per hour of audio, returning speaker-labeled TXT, JSON, SRT, and VTT — a 90-minute deposition is back in the dashboard before the transcriptionist's coffee gets cold.
Upload deposition audio or video files (up to 2 hours and 250 MB each) through the bulk dashboard. Files process in parallel — a batch of 30 depositions completes in roughly the same time as a single 30-deposition file. Speaker identification runs automatically; you don't configure speaker counts or label individual voices manually.
Speaker identification keeps the dialogue distinct
BrassTranscripts Legal's automatic speaker identification labels each speaker turn — distinguishing examining attorney, deponent, opposing counsel, and interpreter — so cross-references and contradictions are searchable by participant rather than buried in a single voice stream.
Speaker labels appear inline in the TXT output (Speaker 1, Speaker 2, etc., with timestamps) and as structured fields in the JSON output. After download, replace the generic Speaker labels with names manually or with one of the AI prompts in the legal toolkit.
AI prompts for case-ready analysis
BrassTranscripts Legal includes a toolkit of legal-specific AI prompts — contradiction analyzer, timeline constructor, cross-examination prep, key facts extractor, legal strategy developer — that turn raw deposition transcripts into structured case work product when piped to ChatGPT, Claude, or your firm's AI tool.
Contradiction Analyzer
Surface contradictions across multiple depositions or between deposition and prior statement.
Timeline Constructor
Extract a chronological timeline of events from witness testimony.
Cross-Examination Prep
Generate cross-examination question outlines based on testimony gaps and contradictions.
Key Facts Extractor
Pull case-relevant facts (names, dates, amounts, locations) into a structured list.
See AI Prompts for the full toolkit.
Working copy, not certified court document
BrassTranscripts Legal produces working-copy transcripts for case preparation, internal review, and AI-assisted analysis — they are not certified court documents and do not replace certified court reporter transcripts when filings or evidence require certification.
Most law firms adopt an AI-first / certify-as-needed workflow: AI-transcribe every deposition for working copies, then order certified transcripts from a court reporter only for the depositions actually filed with the court. This keeps the bulk of case preparation cost-effective without compromising on certification where it's legally required.
Frequently asked questions
Can AI replace certified court reporters for depositions?
No. AI transcripts are not certified court documents and cannot replace certified court reporter transcripts when filings, evidentiary submissions, or court rules require certification. AI transcription handles the volume side of deposition workup (working copies, AI-prompt input, internal review); court reporters handle the certification side.
How accurate is automatic speaker identification in depositions?
BrassTranscripts Legal speaker identification labels each speaker turn with consistent labels (Speaker 1, Speaker 2, etc.). Accuracy is highest when each participant speaks distinctly and cross-talk is minimal — typical deposition dynamics. After download, generic speaker labels can be replaced with names manually or via an AI prompt.
What about video depositions?
Video depositions are supported directly. BrassTranscripts Legal accepts MP4 and MPEG video files (up to 250 MB and 2 hours per file) and processes the audio track of the video without needing audio extraction. Output includes SRT and VTT subtitle formats specifically for syncing transcripts back to the video timeline.
How long does deposition processing take?
BrassTranscripts Legal processes deposition recordings at 1–3 minutes per hour of audio. A 90-minute deposition is back in under 5 minutes. A batch of 30 depositions processes in parallel and typically completes within roughly the same time as the longest single deposition in the batch.
Can I get a discount for ongoing case work?
Bulk pricing automatically rewards larger batches: $4.00 per file at 50-99 files, $3.50 at 100-249, $3.00 at 250+. The account file-count limit also grows with each paid batch (+100 files per batch), so heavy-volume firms can run progressively larger batches without contacting support.
