New research evaluates speech quality metrics for neural audio codecs

A new research paper evaluates 45 objective speech quality metrics to determine their reliability for assessing neural audio codecs. The study found that neural-based metrics, specifically scoreq and utmos, demonstrated the highest correlation with subjective listening scores under clean speech conditions. However, the research also indicated that non-intrusive metrics tend to become less effective when evaluating very high levels of subjective speech quality. AI

IMPACT This research could lead to more accurate and reliable evaluation of neural audio codecs, potentially improving the quality of AI-generated speech and audio processing.

    Assessing speech quality metrics for evaluation of neural audio codecs under clean speech conditions

    arXiv:2509.24457v1 Announce Type: cross Abstract: Objective speech-quality metrics are widely used to assess codec performance. However, for neural codecs, it is often unclear which metrics provide reliable quality estimates. To address this, we evaluated 45 objective metrics by …
