911 and dispatch audio
Emergency calls, radio traffic, and call-center recordings in the common formats agencies produce, from one call to a whole night's worth.
Everything that happened
before help came
The opening minutes of an incident exist only in the 911 and dispatch audio. Sonix transcribes emergency calls at $10 an audio hour, timestamped and speaker-labeled, so the first report, the second caller, and the radio traffic in between read as one sequence rather than three separate files.

Every call about an incident,
in one readable order
Agencies, prosecutors, defense teams, and civil attorneys use Sonix to turn 911 and dispatch recordings into timestamped, speaker-labeled text that rebuilds an incident from the moment the first call came in.
Transcripts in minutes
A recorded call is typically transcribed in minutes at $10 an audio hour, so review starts while the case is still moving.
A timeline, minute by minute
Timestamps on every line 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.
Search every call at once
One query across every call about an incident surfaces an address, a name, or a phrase from any recording in seconds.
Exports for reports and filings
Timestamped transcripts to DOCX or PDF for incident reports, motions, and filings, each quote pointing back to its moment in the audio.
Security that holds up under
legal scrutiny
Every claim below is part of how Sonix runs today, and your agency's IT team can verify all of it.

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.
Three recordings,
one reconstructed sequence
An incident almost never lives in a single call. The first report, a second caller with a different vantage point, and the dispatch traffic between them each hold a piece of what happened before anyone arrived. Transcribing each with timestamps lets them be read as one sequence rather than three files opened in turn.
- 1Gather every call about the incident. Upload the 911 calls, the dispatch radio traffic, and any call-center recordings that touch the incident, from a single call to everything an agency produced that night.
- 2Verify the hard passages against the audio. Emergency audio is messy and accuracy follows the recording. The editor pairs every line with click-to-play audio, so your staff checks the panicked and overlapping stretches against the call itself.
- 3Lay the transcripts into one timeline. With a timestamp on every line, statements from different callers and dispatch updates fall into minute-by-minute order. Search across all of them at once to see what each voice adds.
Messy recordings,
and reconstructing a timeline
How do teams analyze 911 calls?
They transcribe the audio, then read and search it rather than re-listening. Each call becomes timestamped, speaker-labeled text, so investigators and attorneys quote exact words, compare accounts across calls, and tie every statement to the moment it was made. AI summaries give a quick overview of the longer recordings.
Can Sonix rebuild the timeline?
Every line carries a timestamp, so the first report, each dispatch update, and every statement fall into minute-by-minute order. Set transcripts from several calls beside each other and the opening of an incident reads as one reconstruction instead of scattered recordings.
How does it handle poor audio and panicked callers?
Not perfectly, and that is worth saying up front. Accuracy follows audio quality: clean speech reaches up to 99%, while shouting, crying, and crosstalk all need correcting. The editor pairs each line with click-to-play audio, so your staff settles a hard passage against the recording and fixes it in place.
Can I work with several calls about the same incident?
Upload every call and search across all of them at once, so a detail mentioned by one caller surfaces next to what the others reported. Files process in parallel and each transcript keeps its own timestamps, which is what makes comparing accounts quick.
Who uses 911 call analysis?
Agencies reviewing their own dispatch audio, prosecutors preparing cases, defense teams working through discovery, and civil attorneys reconstructing what happened before a crash or an injury. Both sides work from the same recordings, and each team verifies its own transcripts.
What does 911 call transcription cost?
$10 an audio hour, pay as you go, no subscription. The cost per incident stays predictable and small against the hours of re-listening it replaces, and volume pricing is available for teams that review emergency audio every week.
