Pitch
-- Hz
target 203 Hz
Pitch (F0): Fundamental frequency. How high or low your voice sounds. Target range for feminine voice: 180-250 Hz. Watch the line for stability (smooth = controlled) and range (expressive = varied).
Resonance
-- Hz
target 719 Hz
Resonance (F1): First formant. Shaped by jaw openness and vocal tract size. The most important dimension for perceived voice gender. Higher = smaller perceived vocal tract.
Brightness
-- Hz
target 1916 Hz
Brightness (F2): Second formant. Related to tongue position (front vs back). Higher = brighter, more forward placement. Target: 1800-2200 Hz.
Breathiness
-- dB
target 10 dB
Breathiness (H1-H2): Difference between first and second harmonic. Higher = breathier, lighter vocal weight. Lower = more pressed, denser. This relates to vocal weight (saturation).
Clarity
-- dB
target 17 dB
Clarity (HNR): Harmonics-to-Noise Ratio. How clean your voice sounds vs rough/noisy. Above 15 dB = good. Above 20 dB = very clear. Related to breath support and relaxed phonation.
Volume (Intensity): How loud you are. Watch for consistency. Large spikes may indicate pushing. Drops may indicate losing support.
