Voice measurement and human review
Resources for compliance, fraud, and technology teams evaluating voice and channel measurements, recording validity, and evidence for human review.
Voice and channel measurement for human review
Sonotheia measures physical properties of the voice and the channel in call audio and reports each one as nominal, deviated or unavailable, with the validity of the recording. A reviewer decides what to do with the result. Sonotheia does not decide whether a voice is synthetic.
Read solution →Voice and channel measurement for callback and wire workflows
Sonotheia does not verify liveness or identity. The review instrument does not enroll a speaker or compare a caller against an identity. Confirm storage and retention terms for the actual deployment. It measures the voice and the channel in a recorded request and reports what it found, so the person running the callback or approving the wire has evidence beside their own judgment.
Read solution →Voice fraud governance for regulated financial services
Sonotheia provides voice and channel measurements and a structured evidence record for people reviewing voice-driven requests. The record supports a reviewer's judgment; it does not determine fraud, verify liveness or identity, or establish regulatory compliance.
Read solution →Recorded-request review for banking and wire workflows
Sonotheia measures voice and channel properties in recorded requests for banking review, and gives the reviewer a record of what it measured and how valid the audio was.

How to evaluate voice deepfake detection vendors
Evaluate voice-analysis vendors against the decision you need to support, the measured channel, the quality of their evidence and their deployment data terms. Distinguish a detector's classification claim from a measurement instrument and from speaker authentication.
Read resourceVoice measurement benchmark methodology and limits
The benchmark configuration is documented internally, with the corpus, partition and simulated codec chain identified. No headline performance figure is published here. A corpus benchmark does not establish performance on a customer's calls.
Read resourceWhat a phone channel does to voice measurements
Sonotheia's measurements are benchmarked on simulated wideband, G.711 and AMR-NB chains built from public spoofing corpora. They have not been validated on live telephone traffic. A real trunk adds handset, network and transcoding effects the simulation did not include, so it stays pending until measured in place. Zoom, Teams and WebRTC meeting audio are out of scope.
Read resourceVoice review records for compliance teams
A structured measurement record with the instrument version can support a compliance team's own review and SAR narrative preparation. It is not a qualified SAR filing or a determination that a reporting requirement has been met. The institution and its legal reviewers decide what to file.
