911 and dispatch audio
Upload 911 calls, dispatch radio traffic, and call-center recordings in the common audio formats agencies produce, from a single call to a full incident's worth.
The first minutes of every incident, reconstructed in text
What happened before anyone arrived on scene lives in the 911 and dispatch audio. Sonix transcribes emergency calls at $10 per audio hour, with timestamps and speaker labels your own staff verifies in the in-browser editor, so the opening of an incident reads as a timeline.

Every call about an incident,
transcribed and searchable
Agencies, prosecutors, defense teams, and civil attorneys use Sonix to turn 911 and dispatch recordings into timestamped, speaker-labeled transcripts that rebuild an incident from the moment the first call came in.
Transcripts in minutes
A recorded call is typically transcribed in minutes at $10 per audio hour, with up to 99% accuracy on clear audio, so review starts while the case is moving.
A timeline, minute by minute
Timestamps on every line rebuild the incident as it unfolded, so your team can put each statement, siren, and dispatch update in order against the clock.
Caller and dispatcher, separated
Speaker labels split the caller from the dispatcher, so panicked, overlapping exchanges read as a clean script of who said what and when.
Search every call at once
Multi-file search runs one query across every call about an incident, surfacing an address, a name, or a phrase from any recording in seconds.
Exports for reports and filings
Export timestamped transcripts to DOCX or PDF for incident reports, motions, and court filings, with every quote pointing back to its moment in the audio.
Security that stands up to legal scrutiny
Evidence-grade security your agency's IT team can verify: every claim below is part of how Sonix runs today.
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.

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.
From scattered recordings,
to one timeline
An incident rarely lives in a single recording. The first report, the second caller with a different vantage point, and the dispatch traffic in between each hold part of what happened before anyone arrived. Sonix turns each recording into a timestamped transcript, so the opening minutes read as one sequence instead of separate files.
- 1Gather every call about the incident. Upload the 911 calls, dispatch radio traffic, and call-center recordings that touch the incident, from a single call to everything an agency produced that night. Files process in parallel.
- 2Verify the hard passages against the audio. Emergency audio is messy, and accuracy depends on the recording. The in-browser editor pairs every line with click-to-play audio, so your staff checks panicked or overlapping stretches against the call itself.
- 3Lay the transcripts into one timeline. With timestamps on every line, statements from different callers and dispatch updates fall into a minute-by-minute sequence. Search across all the calls at once to see what each voice adds to the reconstruction.
911 call analysis, answered directly
How do teams analyze 911 calls with Sonix?
They transcribe the audio, then read and search it instead of re-listening. Each call becomes a timestamped, speaker-labeled transcript, so investigators and attorneys can quote exact words, compare accounts across calls, and tie every statement to the moment it was said. AI summaries give a quick overview of longer recordings.
Can Sonix rebuild the timeline of an incident?
Yes. Every line of the transcript carries a timestamp, so the first report, each dispatch update, and every statement fall into a minute-by-minute sequence. Lay transcripts from multiple calls side by side and the opening of an incident reads as one reconstructed timeline instead of scattered recordings.
How does Sonix handle poor audio and panicked callers?
Accuracy depends on audio quality: Sonix reaches up to 99% accuracy on clear audio, and difficult stretches will need more correction. The in-browser editor pairs every line with click-to-play audio, so your staff verifies hard passages against the recording itself and fixes them in place.
Can I work with multiple calls about the same incident?
Yes. Upload every call about an incident and search across all of them at once, so a detail mentioned by one caller surfaces alongside what the others reported. Files process in parallel, and each transcript keeps its own timestamps, which makes comparing accounts across callers fast.
Who uses 911 call analysis?
Agencies reviewing their own dispatch audio, prosecutors preparing cases, defense teams reviewing discovery, and civil attorneys reconstructing what happened before a crash or injury. Both sides of a case work from the same recordings, and each team verifies its own transcripts in the in-browser editor.
What does 911 call transcription cost?
Sonix is $10 per audio hour on the pay-as-you-go plan, with no subscription required. Costs stay predictable per incident and small next to the hours of re-listening they replace, and volume pricing is available on plans for teams that review emergency audio every week.
