call-voice-deepfake-liveness-detector skillA

call-voice-deepfake-liveness-detector is agent-read markdown (skill) from calle-ai/awesome-phone-call-agents: Offline experimental scorer of supplied acoustic features for phone-workflow demonstrations. Returns heuristic review suggestions, not caller authentication or a deployed deepfake detector..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

# 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`).

This skill is grounded in the peer-reviewed anti-spoofing literature:
