Every recording in the production,
transcribed and searchable

Defense teams use Sonix to turn discovery productions into timestamped, speaker-labeled transcripts that attorneys, paralegals, and investigators can search in seconds.

Discovery bodycam & dashcam

Hours of body-worn and in-car video from the production become searchable text, with timestamps that tie every statement back to the exact frame.

Interrogation recordings

Full custodial interviews transcribed with speaker labels, so you can trace exactly what was asked, what was answered, and where the account changed.

Jail & detention calls

Recorded facility calls become quotable transcripts within minutes, so your team reviews weeks of calls in an afternoon instead of listening in real time.

911 audio

Emergency calls transcribed with timestamps, ready to compare against the responding officers' reports and the timeline in the complaint.

Witness statements

Recorded statements become organized, searchable text, making it fast to line up what each witness said against their earlier accounts.

Client interviews

Privileged conversations recorded in the office, at the jail, or over the phone become accurate transcripts your team controls end to end.

From Production to Prep

How defense teams work through
large discovery productions

Upload the whole production

Batch-upload bodycam, interrogation video, and jail calls from your computer or from Google Drive, Dropbox, and OneDrive. No per-file babysitting.

AI transcribes in minutes

Automated transcription returns timestamped text while you plan the defense, at $10 per audio hour instead of per-page transcription rates.

Speakers labeled automatically

Officers, clients, and witnesses are separated and labeled across every recording, and your staff can rename or merge speakers in one click.

Staff verify in the browser

Click any word to hear that exact moment. Paralegals and attorneys correct the transcript directly in the browser, no software installs required.

Search every recording at once

Multi-file search finds names, times, and phrases across the entire production in seconds, so one contradictory sentence cannot hide in hour twelve.

Clip and export for motions

Pull timestamped passages for motions and cross-examination prep, then export to DOCX, PDF, or subtitle formats your whole team can use.

Security & Trust

Privileged client recordings demand more than promises. Every claim below is part of how Sonix runs today, and it can all be verified before you upload a single file.

SOC 2 Type II certified

Independently audited every year against the highest standards for security, availability, and confidentiality — with continuous monitoring of 100+ internal controls.

HIPAA BAA available

Sonix signs Business Associate Agreements on Enterprise plans and implements the required safeguards — relevant for personal-injury, medical-malpractice, and health-records evidence.

No AI training on your data

Nothing you upload is ever used to train our systems — or anyone else's. Your recordings and transcripts remain strictly confidential and are never sold or shared.

Encrypted at every layer

TLS encryption for every transfer and AES-256 server-side encryption at rest — one of the strongest block ciphers available — across our database and file storage.

Role-based access & 2FA

Grant and revoke team access quickly with multiple permission levels, require two-factor authentication, and password-protect shared files.

You control your data

View, export, and delete your files at any time — deleted audio and transcripts are completely wiped. GDPR-ready, with DPA and SCC available on request.

Common Questions

Criminal defense transcription,
answered directly

How do small defense teams review hours of discovery video?

They transcribe it and read instead of watch. Sonix turns a discovery production of bodycam, interrogation video, and jail calls into timestamped transcripts in minutes, so a solo attorney or a two-paralegal office can scan, search, and flag key moments without assigning someone to watch footage in real time.

Can Sonix find a specific statement across many recordings?

Yes. Multi-file search scans every transcript in your case at once, so you can type a name, a time, or a phrase and see each recording where it appears. Click a result to hear that exact moment, which turns hunting for one statement into a seconds-long lookup.

Are Sonix transcripts admissible in court?

Sonix produces fast working transcripts, not certified court records. Your own staff verifies and corrects every transcript in the in-browser editor, and whether a transcript can be used in a proceeding depends on your jurisdiction's rules and is the attorney's call. Most teams use Sonix for review, prep, and drafting.

Is Sonix secure enough for privileged client recordings?

Yes. Sonix is SOC 2 Type II audited every year, encrypts files in transit and at rest with AES-256, and never uses your recordings to train AI models. Role-based access controls and two-factor authentication let you limit privileged material to the people working the case.

Can solo attorneys and public defenders afford Sonix?

Yes. Pay-as-you-go transcription is $10 per audio hour with no subscription required, so you pay only for the recordings you actually transcribe. That pricing puts full-production review within reach of solo practices and public defender offices that could never justify outsourced per-page transcription rates.

How fast is turnaround before a hearing?

A one-hour recording is typically transcribed in minutes, and files process in parallel, so a batch uploaded in the evening is searchable the same night. There is no human review queue: your staff verifies transcripts in the editor as soon as they are ready, even the morning of a hearing.
