Insufficient Vibrato

颤音不足

Vocal Science Principle

Insufficient vibrato — vibrato is underdeveloped or lacking in rate/extent.

Detection criteria:

  • Vibrato rate below lower bound of configured range, OR
  • Vibrato extent below lower bound of configured range
  • Minimum vibrato presence required (rate > 0.5 Hz or extent > 5 cents)
  • No vibrato at all is considered normal (not flagged)

    • When vibrato is present but weak, it may indicate excessive muscular control or tension preventing natural oscillation.

    健康的颤音是喉部肌肉放松的表现
