Deposition Transcription: How Law Firms Do It

A deposition generates two very different transcription needs, and law firms that treat them as one problem overpay for both. The official record needs a certified court reporter. The twenty other things a litigation team does with testimony, searching it, summarizing it, checking it against prior statements, need a fast, cheap working copy, and that is where AI transcription has changed how firms work.

The numbers make the split obvious. A certified deposition transcript typically costs $500 to $2,000 or more. An AI working copy of the same two-hour recording costs $6.00 at BrassTranscripts and arrives in minutes. Firms that AI-transcribe everything and certify only what gets filed cut transcription spend dramatically without giving up a single certified page where the rules require one.

The Two-Track Workflow Law Firms Use

The prevailing 2026 workflow is AI-transcribe everything, certify only for filing: every deposition recording gets an immediate AI working copy for case preparation, and certified court reporter transcripts are ordered only for recordings that will be filed with the court or entered into evidence. This keeps certified costs limited to the documents that legally require certification.

The reason this works is that most deposition transcript use never touches a courtroom. Associates search testimony for admissions. Paralegals build chronologies. Partners compare a witness's answers against interrogatory responses. None of that requires certification. It requires text that is searchable, speaker-labeled, and available the same day.

Legal work is already moving this direction broadly. The 2025 Thomson Reuters Future of Professionals Report found document review (77%), legal research (74%), and document summarization (74%) are the top AI use cases among legal professionals. Deposition working copies sit squarely in that document-review category. The law firm transcription guide covers the full workflow; this post focuses on the deposition-specific pieces.

What an AI Working Copy Gives You

BrassTranscripts turns a deposition recording into a speaker-labeled, timestamped transcript in roughly 1-3 minutes of processing per hour of audio, with automatic speaker identification handling up to 6 distinct voices. The output arrives in four formats (TXT, SRT, VTT, and JSON), so the same job feeds a readable document, a video-synced caption file, and structured data for analysis tools.

Speaker labels matter more in depositions than almost anywhere else. A transcript that cannot distinguish the deposing attorney from the witness is nearly useless for contradiction work. Automatic diarization separates each voice with timestamps, and a find-and-replace turns Speaker A and Speaker B into names in a couple of minutes.

The working copy also becomes raw material for analysis. BrassTranscripts publishes AI prompts built for legal workflows, including a deposition contradiction-analysis prompt that checks testimony against prior statements, and a paralegal review and tagging system for working through transcript batches methodically. Text in, case-ready notes out.

Deposition Transcription Costs in 2026

A two-hour deposition recording costs $6.00 to transcribe as a BrassTranscripts working copy, against $500 to $2,000 or more for a certified court reporter transcript of the same testimony. For internal case preparation, that is a working copy at around one percent of the certified price.

Single-file pricing is flat by duration: $2.50 for recordings 15 minutes and under, $6.00 for anything 16 minutes or longer. There is no subscription and no minimum commitment; you pay per file.

Case backlogs change the math further. Bulk processing prices long recordings on a sliding schedule, $6.00 per file at 1-5 files down to $3.00 per file at 250 or more, with short recordings on a parallel $2.50-to-$1.25 track. A discovery production with forty hearing and deposition recordings lands at $4.50 per long file. The bulk calculator for law firms walks through when batch pricing beats single-file uploads, and the bulk service itself was built for a legal case: a paralegal with 102 audio files from a highway construction dispute.

One practical note: the upload limit is 450MB per file, with no enforced duration limit — that ceiling covers several hours of typical recorded audio. If a long deposition produces a file larger than 450MB, split the recording at a break. Most recording software exports segments in seconds, and morning-session and afternoon-session files are easier to work with anyway.

Handling Privileged Recordings

Disclosing a recording to a transcription service does not automatically waive privilege, and the ABA's Formal Opinion 477R (2017) confirms attorneys may use third-party technology services provided they exercise reasonable care over confidentiality. The care obligations point at data handling, which is where a service's retention policy matters.

BrassTranscripts deletes uploaded audio 24 hours after upload and completed transcripts 48 hours after processing. Nothing is retained after those windows, and audio is never used to train AI models. Files are encrypted in transit and at rest. The operational habit to build: download transcripts promptly and move them into the firm's document management system with the same access controls as any privileged material. The attorney-client privilege analysis covers the ethics-opinion landscape in depth.

Recording consent is the other compliance edge. Deposition recording is governed by procedure rules and stipulations, but firms transcribing client calls and witness interviews should know their state's consent requirements; the state-by-state recording laws guide maps them.

Working With Deposition Recordings in Practice

Audio quality determines transcript quality, and deposition audio is usually good: an indoor room, seated speakers, and turn-taking enforced by procedure. The recurring problems are crosstalk during objections and distant audio from a phone or laptop microphone at the far end of a conference table.

Three habits fix most of it. Place the recorder or microphone centrally rather than next to one party. Ask for verbal answers, the court reporter needs them anyway, and nods transcribe as silence. And when objections produce overlapping speech, expect the transcript to interleave the voices; the timestamps make those passages easy to find and check against the audio.

For remote depositions, the platform's own recording is normally the best source file. Export the audio, split it only if the file exceeds 450MB, and upload. Processing at 1-3 minutes per audio hour means a morning session is searchable before the afternoon session starts.

Frequently Asked Questions

How do law firms transcribe depositions?

Most firms use a two-track workflow. A certified court reporter produces the official transcript for any deposition that will be filed or entered into evidence. For case preparation, review, and discovery organization, firms increasingly run the deposition audio through AI transcription to get a working copy in minutes instead of days. BrassTranscripts processes a recording in roughly 1-3 minutes per hour of audio and labels each speaker automatically, so attorneys can search and annotate testimony the same day it was taken.

How much does deposition transcription cost?

Certified court reporter transcripts typically run $500 to $2,000 or more for a full deposition, depending on page count, turnaround, and location. An AI working copy of the same recording costs $6.00 at BrassTranscripts for any file 16 minutes or longer, or $2.50 for recordings 15 minutes and under. Firms with case backlogs use bulk processing, where the long-file rate scales from $6.00 down to $3.00 per file as batch size grows.

Are AI deposition transcripts admissible in court?

No. AI transcripts are not certified court documents and cannot replace a certified court reporter transcript for official filings or evidence. Their role is internal: case preparation, contradiction checks, timeline building, and deciding which recordings are worth ordering certified transcripts for. The common pattern is to AI-transcribe every recording for working copies, then certify only the subset that will be filed.

Is AI transcription safe for privileged deposition recordings?

Using a third-party transcription service does not automatically waive attorney-client privilege, and the ABA's Formal Opinion 477R (2017) confirms attorneys may use cloud technology services with reasonable care. BrassTranscripts deletes uploaded audio 24 hours after upload and transcripts 48 hours after processing, retains no copies afterward, and never uses client audio for AI training. Download the transcript within the 48-hour window and store it in your firm's document management system.
