Every recording in the case file,
transcribed and searchable
Licensed PIs, insurance SIU teams, and corporate investigators use Sonix to turn long field recordings into timestamped, speaker-labeled transcripts they can search in seconds. Police and government agencies have a dedicated Sonix page for law enforcement.
Field & subject interviews
Interviews captured on a phone or recorder in the field become organized, quotable transcripts within minutes of upload, with each speaker labeled.
Recorded claimant statements
Insurance and SIU teams get speaker-labeled transcripts of recorded statements in minutes, with the questioner and claimant separated across the entire session.
Witness locates & background interviews
Conversations from locates, canvasses, and background work become searchable notes, so names, addresses, and details never get lost between cases.
Phone & call recordings
Recorded calls are transcribed with precise timing and speaker labels, ready to align against case timelines and claim files.
Case file audio archives
Years of old recordings become a searchable archive. Reopen a file and find every mention of a subject in seconds instead of re-listening.

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.
From Stakeout to Searchable the Same Day
I used to lose my evenings scrubbing surveillance audio for one admission. Now the transcript is waiting before I am back at the office, and I search the whole case for a name or a plate in seconds.
Investigator transcription,
answered directly
Can Sonix handle long, low-quality surveillance audio?
Yes, with the caveat that accuracy always depends on audio quality. Clear speech transcribes at up to 99% accuracy, while distant or muffled voices need more correction. The in-browser editor makes fixes fast: click any word to hear that exact moment, verify it, and move on.
Can I search across every recording in a case?
Yes. Multi-file search scans all of your transcripts at once, so a subject's name, a plate number, an address, or a phrase surfaces from any recording in seconds. Every result is timestamped, and clicking it plays the exact moment in the original audio or video.
Does Sonix work for insurance recorded statements and EUO prep?
Yes. SIU and claims teams upload recorded claimant statements and get timestamped, speaker-labeled transcripts in minutes, with the questioner and claimant separated automatically. Adjusters and counsel search past statements for inconsistencies and pull quotable excerpts when preparing for an examination under oath.
Is Sonix discreet enough for client work product?
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 and two-factor authentication control who sees a case, and permanent deletion controls let you decide how long files exist.
How much does transcription cost for a small agency?
Sonix is $10 per audio hour on the pay-as-you-go plan, with no subscription required. A one-hour subject interview costs $10, transcribed in minutes instead of billed by the page. Solo PIs pay only for what they upload, and subscription plans add volume discounts as caseloads grow.
Can I record interviews in the field on my phone?
Yes. The Sonix mobile app records interviews on your phone and uploads them for transcription on the spot, and files from any voice recorder app work too. By the time you are back at the office, the interview is a timestamped transcript ready to verify and quote.
