Phoneme-level analysis improves detection of emotionally manipulated synthetic speech

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for detecting deepfake audio by analyzing speech at the phoneme level. This approach, which uses self-supervised embeddings, proved more effective than previous methods that treated speech as a uniform signal. The study found that certain phonemes, particularly complex vowels and fricatives, show greater divergence in synthetic speech, making them key indicators for identifying manipulated audio across various emotions and synthesis systems.

    Phoneme-Level Deepfake Detection Across Emotional Conditions Using Self-Supervised Embeddings

    arXiv:2605.03079v1 Announce Type: cross Abstract: Recent advances in emotional voice conversion (EVC) have enabled the generation of expressive synthetic speech, raising new concerns in audio deepfake detection. Existing approaches treat speech as a homogeneous signal and largely…
