Fairness Adjusted ASR Score Metric

🎯 FAAS-Metric

FAAS (Fairness Adjusted ASR Score) is a fairness-aware evaluation metric for Automatic Speech Recognition (ASR) systems. It combines traditional ASR accuracy (like WER) with fairness evaluations across demographic groups to provide a holistic performance measure.

📦 Installation

pip install faas-metric

🚀 Usage

▶️ Python API

from faas_metric import compute_faas

# Example input
wer_list = [12.5, 15.0, 9.0]
speaker_metadata = [
    {"gender": "male", "first_language": "Hindi"},
    {"gender": "female", "first_language": "Tamil"},
    {"gender": "male", "first_language": "Bengali"}
]

# Compute FAAS score
faas = compute_faas(wer_list, speaker_metadata)
print(f"FAAS Score: {faas}")

---

🖥️ Command Line Interface (CLI)

faas --input path/to/data.csv --output path/to/result.json

📄 Input CSV Format

Your CSV should include:

• A wer column (Word Error Rate)
• Any number of fairness-related attributes like gender, first_language, ethnicity, etc.

Example:

wer,gender,first_language
12.5,male,Hindi
15.0,female,Tamil
9.0,male,Bengali

✅ Output

A JSON file (if --output is specified), or the FAAS score printed to the terminal:

{
  "faas_score": 88.0
}
