Every recording your firm handles,
transcribed and searchable
Litigation teams use Sonix to turn deposition video, hearing audio, and client recordings into timestamped, speaker-labeled transcripts that attorneys and paralegals can search across every matter.
Hearings & arbitrations
Motion hearings, arbitration sessions, and oral arguments transcribed with precise timing, ready to cite in briefs and post-hearing submissions.
Client interviews & intake calls
Consultations and intake calls become organized transcripts your whole team can revisit, so details shared in the first meeting never get lost.
Witness preparation sessions
Prep sessions transcribed with speaker labels, so attorneys can compare what a witness said in prep against prior statements and deposition testimony.
Independent medical examinations
IME recordings in injury and malpractice matters transcribed with timestamps, with a HIPAA BAA available on Enterprise plans for medical evidence.
Recorded statements
Party and witness statements captured on phones or recorders become quotable, timestamped transcripts within minutes of upload.
How litigation teams work through
a matter's recordings
Upload depositions and hearings in bulk
Batch-upload deposition video, hearing audio, and interview files from your computer or from Google Drive, Dropbox, and OneDrive, without babysitting each file.
AI transcripts in minutes
Automated transcription returns timestamped text while testimony is still fresh, at $10 per audio hour instead of per-page agency rates.
Speakers labeled automatically
Attorneys, deponents, and experts are separated and labeled automatically, and your team can rename or merge speakers in one click.
Paralegals verify in the browser
Click any word to hear that exact moment. Paralegals correct the transcript directly in the in-browser editor, no software installs required.
Search across every matter
Multi-file search finds names, dates, exhibits, and phrases across every recording in a matter, or the firm's whole library, in seconds.
Export and share firm-wide
Export to DOCX or PDF for work product, then share with permission levels and password-protected links so the right people see the right matters.
Run every matter through one shared workflow
A transcription tool that works for one person becomes a problem at firm scale, where every matter has many hands on it.
Five attorneys with five personal accounts and five filing systems means five places a transcript can hide when the matter goes to trial. Sonix is organized the way a firm is organized instead.
A shared home for every matter
Team folders give each matter, client, or practice group its own shared home. When a paralegal uploads deposition media to the matter folder, everyone with access to that folder sees the transcript the moment it is ready: no forwarding, no duplicate copies, and no asking who has the latest version.
Permissions that follow the matter
Administrators set access at the account, folder, and file level. A litigation paralegal can edit everything in their matters while a contract attorney reads one folder and nothing else, and clients or outside experts can receive a password-protected, read-only link instead of a login.
A built-in paralegal-to-attorney handoff
Sonix uses focused, turn-based editing: one person edits at a time while everyone else reads, searches, and leaves notes on specific paragraphs. A paralegal verifies speaker labels, fixes names, and corrects the transcript against the audio, and the reviewing attorney answers in paragraph notes instead of a separate email thread. Version history captures every change, so nothing is overwritten and review work is never lost.
One standard for every office
Every transcript exports the same way, with timestamps and speaker labels carried through, so work product looks consistent no matter which office or which paralegal prepared it. New hires learn one system instead of each attorney's private method.
Admin controls built for firm IT, not just power users
The person who approves Sonix at a firm is rarely the person who uses it most, so these are the controls that matter to the administrator, IT manager, or managing partner who owns the account.
Roles and permissions
Control what each person can do with a transcript, from viewing and editing to sharing, exporting, and deleting, and lock sensitive matters down tighter than the general library.
Sign-in security
Two-factor authentication is available on every account and works with authenticator apps such as Google Authenticator, Authy, and 1Password. Enterprise plans add single sign-on through SAML identity providers, including Okta, Azure AD, and OneLogin, plus SCIM user provisioning, so access is granted and revoked through the directory your IT team already manages.
Audit logs on Enterprise plans
Enterprise plans log every action in the account with a timestamp and the user who took it, so you can see who accessed a file, changed a transcript, or shared it. When someone asks who opened a recording and when, the answer is in the log, not in anyone's memory.
Retention and network controls
Enterprise plans add custom data retention controls and IP restrictions, so the account can follow the firm's own document retention schedule and network policy instead of a vendor's defaults.
Billing that accounting will accept
All transcription and translation costs consolidate into one invoice, with breakdowns by user, project, or department. The Billing Administrator role is free, so the accounts payable team can see invoices and payment history without taking a paid seat.
The Sonix admin tools page covers each control in full detail, written for the administrator or IT manager running exactly this review.
Security that holds up under
legal scrutiny
Client confidentiality is not negotiable. Every claim below is part of how Sonix runs today, and your firm's IT team can verify all of it.
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, which matters 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 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 both 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.
The questions your IT committee will ask
Most firms route new software through a security review, and every answer below is documented on the Sonix site or available from legal sales.
The six controls above cover the audit, encryption, AI training, access, the BAA, and deletion. Once those are settled, a committee usually adds these four questions.
- Can Sonix staff open our files?
- Not without your permission. Sonix employees cannot open your files unless you give express written consent to investigate an issue, so support never becomes a back door into a privileged matter.
- Where is client data stored?
- All data is stored at AWS in the USA, in enterprise-grade facilities with around-the-clock monitoring and on-site security staff. Enterprise customers can ask about data residency options for a specific region.
- What can the firm get in writing?
- A DPA and SCC on request, a HIPAA Business Associate Agreement on Enterprise plans, and custom NDA and MSA terms, arranged through legal sales before the first upload.
- Is the platform tested independently?
- Independent security firms run annual network and application penetration tests, with summaries shared under NDA, and every Sonix employee completes security training each year.
For vendor questionnaires or anything beyond the published material, our legal sales team will walk your committee through it. The Sonix security overview covers the full stack.
Deposition volume without the review queue
Litigation volume arrives in bursts, and per-page pricing turns every burst into an invoice that depends on how much was said and how fast you need it back.
Built for bursts
Upload a multi-day deposition as one batch. Files process in parallel, and a one-hour recording typically comes back in 5 to 6 minutes, timestamped and speaker-labeled while testimony is still fresh. No queue of human transcriptionists sits between your paralegals and the working draft.
Priced by the audio hour, not the page
Per-page transcription bills grow with testimony length, speaking speed, and rush fees. Per-audio-hour billing grows only with the length of the recording: a one-hour recording costs the same whether it holds two thousand words or twelve thousand, and the price is known before anyone presses upload. That makes transcription a line item litigation support can budget.
Plans that match firm volume
Pay-as-you-go transcription is $10 per audio hour with no subscription required. Firms with steady monthly volume save with subscription plans, and enterprise plans add volume pricing alongside single sign-on and consolidated administration for multi-office rollouts.
From Client Call to Searchable Record
I can pull up exactly what a client said eight months ago in seconds. Nothing gets lost between meetings anymore.
Where litigation teams go deeper
The firm account is the foundation, and each page below covers what a specific team builds on top of it.
Deposition summaries
AI summaries turn a verified deposition transcript into key points and themes, drafts your attorneys check against the timestamped testimony before taking them into motion practice.
Evidence review
Work through the recorded portion of a production as text: search every recording at once, anchor the moments that matter to timestamps, and leave the recordings untouched as the source.
Case chronologies
Search every recording for dates and events, then pull each statement with its timestamp and speaker, so the timeline your team assembles traces back to the moment it was said.
Case chronologies from transcripts
Individual attorneys
For one attorney's practice rather than a firm, the solo workflow runs from the intake call to the prep session, with dictated memos and the billable-hours math along the way.
The full legal platform
Sonix Legal brings every legal workflow together, from depositions and bodycam audio to real-time transcription and integrations with the legal software your firm already uses.
Multilingual matters without translation guesswork
Firms that handle immigration, international arbitration, or multilingual client bases do not get to choose the language the evidence arrives in.
Sonix transcribes 54+ languages and translates transcripts into 54+, so an interpreted deposition or a Spanish-language client interview goes through the same firm workflow as everything else.
The order of operations is the honest part. Sonix transcribes the recording in its source language first, then translates, so a bilingual paralegal or reviewing attorney can verify the original words before anyone relies on the translated version.
Translation accuracy depends on audio quality and the language pair, so recordings destined for critical use deserve review time. Filings that require a certified translation still go through your certified process: Sonix gives the firm a fast, reviewable working layer, not a substitute for sworn translation where a court demands one.
Law firm transcription, answered directly
What is the best way to set up Sonix for a law firm?
Start with a folder structure that mirrors your matters, then add attorneys and paralegals with the permission level each role needs. Team folders keep everyone with access to a matter in sync, so new transcripts appear the moment they are ready. Administrators manage users and billing from one account, and legal sales can plan the firm-wide rollout with you.
Can paralegals and attorneys work on the same transcript?
Yes. Sonix uses focused, turn-based editing: a paralegal verifies and corrects the transcript in the in-browser editor while attorneys read, search, and leave paragraph-level notes. When the paralegal finishes, anyone with edit access picks up the work. Version history captures every change, so nothing is overwritten and no edits are lost.
Does Sonix support SSO and role-based permissions for law firms?
Yes. Permissions are set at the account, folder, and file level, and administrators can restrict who shares, exports, or deletes content. Two-factor authentication is available on every account. Enterprise plans add SSO through SAML identity providers, including Okta, Azure AD, and OneLogin, plus SCIM user provisioning and policies for the whole organization.
How secure is Sonix for confidential client recordings?
Sonix is SOC 2 Type II certified and audited every year, with more than 100 internal controls monitored continuously. Files are encrypted with TLS in transit and AES-256 at rest, and nothing you upload is used to train AI models. A HIPAA Business Associate Agreement is available on Enterprise plans for medical evidence.
How fast can Sonix transcribe a full day of deposition testimony?
Minutes, not days. Files process in parallel, so a litigation team can upload every session from a multi-day deposition at once and receive timestamped, speaker-labeled transcripts while testimony is still fresh. There is no review queue to wait through: paralegals verify transcripts in the browser as soon as they are ready.
How much does law firm transcription cost with Sonix?
Pay-as-you-go transcription is $10 per audio hour, with no subscription required to start. Firms with steady volume save with subscription plans, and Enterprise plans add volume pricing, SSO, and a HIPAA BAA. Because billing is per audio hour rather than per page, costs scale with recording length, not with how fast people spoke.
Does Sonix integrate with Clio and standard legal export formats?
Yes. Send transcripts to Clio in one click, or connect other tools in your stack through Zapier. Export to DOCX and PDF for work product, or SRT and VTT for video evidence, with timestamps and speaker labels carried through every export. To automate uploads and retrieval, firms can use the Sonix API.
Can Sonix handle recordings in languages other than English?
Yes. Sonix transcribes 54+ languages and translates transcripts into 54+. It transcribes the source language first, then translates, so a bilingual reviewer can verify the original transcript before anyone relies on the translation. Translation accuracy depends on audio quality and the language pair, so plan review time for critical evidence.
