AI Audio Detector

Checks whether speech in an audio clip is AI-generated or voice-cloned.

Slug	ID	Status	Tagged	Model version
`ai-audio-detection`	`2`	Active	Yes	`v2-MILE-Ensemble`

What it detects

Detects	Does not detect
AI-generated or voice-cloned speech	Background-noise editing, simple splicing of real recordings, or non-speech AI-generated sounds

The clip is analyzed in 4-second windows, and the overall score combines them.

Request

Slot	Accepted `contentType`
`original`	`audio/mpeg`, `audio/wav`, `audio/m4a`

Result

Uses the standard result fields, plus:

Field	Type	Description
`windows`	object	One entry per 4-second window, keyed by time range (e.g. `"0-4s"`). Each has `RealConfidencePercent`, the real confidence (0–100) for that window

Each window entry, and the result itself, also has a spectrogram path. These paths are internal and can't be downloaded; use the image artifacts instead.

{
  "isFake": false,
  "confidencePercent": 54.18,
  "fakeConfidencePercent": 45.82,
  "realConfidencePercent": 54.18,
  "tag": "likely_real",
  "tagBoundaries": { "real": 30, "likelyReal": 50, "likelyFake": 75 },
  "modelVersion": "v2-MILE-Ensemble",
  "windows": {
    "0-4s": { "RealConfidencePercent": 15.62, "spectrogram": "/app/jobs/560/output/spectrogram_window_0.png" },
    "4-8s": { "RealConfidencePercent": 98.02, "spectrogram": "/app/jobs/560/output/spectrogram_window_1.png" },
    "8-12s": { "RealConfidencePercent": 15.29, "spectrogram": "/app/jobs/560/output/spectrogram_window_2.png" }
  },
  "spectrogram": "/app/jobs/560/output/spectrogram.png"
}

Low window scores show where in the clip the model found synthetic speech.

Output artifacts

`kind`	File	Description
`result`	`result.json`	Full result with the raw probabilities
`image`	`spectrogram.png`	Spectrogram of the whole clip with per-window confidence overlays
`image`	`spectrogram_window_N.png`	One spectrogram per 4-second window (`metadata.window` gives the time range)

Download them from artifacts on GET /jobs/{id}.
