Training an Audio Quality Detection Model Using Synthetic Noise and PESQ Scoring

This article explains how to generate low‑quality audio samples from clean speech by randomly inserting noise at various SNR levels, compute objective PESQ scores as ground‑truth, and use these paired data to train a neural‑network model for reference‑free audio quality assessment.
