Jabberjay 🦜

One API. Every state-of-the-art synthetic voice detector.

Why Jabberjay?

Synthetic voice detection is a fragmented landscape — state-of-the-art models are scattered across research repositories, each with its own dependencies, input formats, and output conventions. Jabberjay brings them all under one consistent Python API and CLI so you can detect AI-generated speech without wrestling with model internals.

• Seven model families — ViT, AST, Wav2Vec2, HuBERT, WavLM, RawNet2, and a classical baseline
• Unified output — every model returns the same DetectionResult with label, confidence, and scores
• Zero boilerplate — pass a file path, get a verdict; models are downloaded and cached automatically
• Flexible — use strings for quick experiments, enums for IDE autocomplete, or pre-load audio to run multiple models on the same clip

$ jabberjay interview.wav
Bonafide ✔️  (94.1% confidence, model=VIT)

$ jabberjay suspicious.wav -m HuBERT
Spoof ❌  (97.8% confidence, model=HuBERT)

Installation

pip install jabberjay

Requires Python ≥ 3.10. Models are downloaded from Hugging Face Hub on first use and cached locally.

---

Quickstart

from Jabberjay import Jabberjay

jj = Jabberjay()
result = jj.detect("audio.wav")

print(result)              # Bonafide ✔️ (94.1% confidence, model=VIT)
print(result.label)        # "Bonafide"
print(result.is_bonafide)  # True
print(result.confidence)   # 0.941

Usage

Command Line Interface

usage: jabberjay [-h] [-m {AST,Classical,HuBERT,RawNet2,VIT,Wav2Vec2,WavLM}]
                 [-d {ASVspoof2019,ASVspoof5,VoxCelebSpoof}]
                 [-vis {ConstantQ,MelSpectrogram,MFCC}] [-v]
                 audio

# Quickstart — VIT with ConstantQ on VoxCelebSpoof (defaults)
jabberjay audio.wav

# Self-contained models (no dataset or visualisation required)
jabberjay audio.wav -m Wav2Vec2
jabberjay audio.wav -m HuBERT
jabberjay audio.wav -m WavLM
jabberjay audio.wav -m RawNet2

# AST with a specific dataset
jabberjay audio.wav -m AST -d ASVspoof2019

# VIT with full options
jabberjay audio.wav -m VIT -d ASVspoof5 -vis MelSpectrogram

# Verbose output
jabberjay audio.wav -v

Python API

All public names are importable from the top-level package:

from Jabberjay import Jabberjay, DetectionResult, Model, Dataset, Visualisation

Choosing a model

String names and enum values are both accepted:

jj = Jabberjay()

# Self-contained models — no extra arguments needed
result = jj.detect("audio.wav", model="Wav2Vec2")
result = jj.detect("audio.wav", model="HuBERT")
result = jj.detect("audio.wav", model="WavLM")
result = jj.detect("audio.wav", model="RawNet2")
result = jj.detect("audio.wav", model="Classical")

# AST — requires a dataset
result = jj.detect("audio.wav", model="AST", dataset="VoxCelebSpoof")

# VIT — requires a dataset and a visualisation
result = jj.detect("audio.wav", model="VIT", dataset="ASVspoof5", visualisation="MFCC")

# Enums give IDE autocomplete and catch typos at import time
result = jj.detect(
    "audio.wav",
    model=Model.VIT,
    dataset=Dataset.ASVspoof5,
    visualisation=Visualisation.MFCC,
)

DetectionResult

Every call to detect() returns a DetectionResult regardless of the model used:

Attribute	Type	Description
label	str	"Bonafide" or "Spoof"
is_bonafide	bool	True if the audio is classified as genuine
confidence	float	Confidence score for the top prediction (0.0–1.0)
model	Model	The model that produced this result
scores	list[dict] | None	Full label/score breakdown for VIT, AST, Wav2Vec2, HuBERT, and WavLM (sorted highest-first); None for Classical and RawNet2

if result.is_bonafide:
    print(f"Genuine voice detected with {result.confidence:.1%} confidence")
else:
    print(f"Synthetic voice detected with {result.confidence:.1%} confidence")

# Full per-label scores
if result.scores:
    for entry in result.scores:
        print(f"  {entry['label']}: {entry['score']:.3f}")

Pre-loading audio

Use load() when running multiple models on the same clip to avoid re-reading the file:

audio = jj.load("audio.wav")  # returns (samples, sample_rate)

results = [
    jj.detect(audio, model="Wav2Vec2"),
    jj.detect(audio, model="HuBERT"),
    jj.detect(audio, model="VIT", dataset="VoxCelebSpoof", visualisation="ConstantQ"),
]

Discovering available options

jj.list_models()         # prints and returns list[Model]
jj.list_datasets()       # prints and returns list[Dataset]
jj.list_visualisations() # prints and returns list[Visualisation]
