Offline experimental scorer of supplied acoustic features for phone-workflow demonstrations. Returns heuristic review suggestions, not caller authentication or a deployed deepfake detector.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Voice Deepfake Liveness Detector This skill directly addresses one of the most urgent and growing threats in telephony: **AI-powered voice cloning fraud**. With tools like ElevenLabs and VALL-E, a bad actor can clone a person's voice from just a few seconds of audio and use it to impersonate family members, executives, or even government officials in phone calls. Unlike transcript-oriented `call-fraud-shield`, this prototype accepts three already-extracted numeric acoustic features. It includes no raw-waveform extraction, telephony middleware, call blocking, identity verification, or audit logger. Its synthetic-fixture labels are advisory examples, not proof that a caller is human or synthetic. > **Note**: This skill and `call-fraud-shield` are *complementary*, not competing. Together, they form a two-layer defense: acoustic (this skill) + semantic (`call-fraud-shield`). ## Scientific Foundation This skill is grounded in the peer-reviewed anti-spoofing literature: …

How to install
mdr add calle-ai/awesome-phone-call-agents/call-voice-deepfake-liveness-detector@sha256:d4aa60a5139f6e5fThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
