I can't scream when facing an attacker

Sudden voicelessness during an attack is a common sideration symptom. Larynx muscles contract involuntarily, cutting the voice. It is neurological, not psychological.

なぜ起こるのか — メカニズム

The vagus nerve controlling the larynx is the first hit by the freeze response. Tian et al 2020 (Anesthesiology): under acute stress 35% of subjects lose voice temporarily. Screaming needs diaphragm + vocal cords + breath coordination — 3 systems that can each lock independently.

アヴィクザール体系の応答

Yehouda teaches the 'low kiai' — a diaphragm grunt, not a throat scream. Easier to produce under stress as it bypasses the locked larynx. Combined with forced exhale, it reboots breathing and unfreezes.
