# Register — VoiceNet dimension guide

*Category:* Speaker Identity · *code:* `vn_REGS` · *slot:* 53

This dimension measures the dominant musical tessitura / pitch-class of the voice. Merge the `__high` / `__low` LoRA from `laion/moss-voicenet-dimension-loras` at 25/50/75/100/125%. Costs are shifts vs. the 24-sample neutral baseline.

**TL;DR.** **Register** controls the dominant musical tessitura / pitch-class of the voice. The **__high** LoRA shifts it +0.61 at 125% (worst cost: burst-blend -0.23); the **__low** LoRA shifts it -0.21 at 100% (worst cost: burst-blend -0.17). The **__high** direction is the stronger, more reliable knob here.

## ▲ HIGH — Register __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.214 | — | — | — | — |
| 25% | 0.422 | +0.21 | +0.02 | +0.02 | +0.05 |
| 50% | 0.663 | +0.45 | -0.03 | -0.20 | +0.03 |
| 75% | 0.684 | +0.47 | -0.07 | -0.26 | -0.05 |
| 100% | 0.788 | +0.57 | -0.05 | -0.23 | -0.03 |
| 125% ★ | 0.823 | +0.61 | -0.07 | -0.23 | -0.14 |

- **EmoNet emotion** — ↑ Impatience and Irritability (+0.52), Elation (+0.50), Pleasure/Ecstasy (+0.37); ↓ Longing (-0.69), Sexual Lust (-0.64), Infatuation (-0.52)
- **VoiceNet dimension** — ↑ Mask Resonance (+0.91), Valence (+0.88), Nasal Resonance (+0.87); ↓ Perceived Gender (-0.94), Cognitive Load (-0.78), Chest Resonance (-0.75)

Merging **Register __high** lifts the dimension: at the recommended **125%** dose the measured Register score moves from a 0.21 baseline to 0.82 (a +0.61 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is a real cost — the biggest hit is to **burst-blend** (-0.23); across the board genuineness -0.07, burst-blend -0.23, speech quality -0.14. Emotionally it reads as Impatience and Irritability (r 0.52), Elation (0.50) and Pleasure/Ecstasy (0.37), and it moves away from Longing, Sexual Lust and Infatuation. On other voice dimensions it co-moves most with Mask Resonance (0.91), Valence (0.88) and Nasal Resonance (0.87), while pulling down Perceived Gender, Cognitive Load and Chest Resonance. Practical call: merge __high at **100–125%**; expect Impatience and Irritability and Mask Resonance to rise and burst-blend to fall. If you don’t want Impatience and Irritability bleeding in, offset it with a prompt cue toward Longing to keep the register shift without the side-effect.

## ▼ LOW — Register __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.214 | — | — | — | — |
| 25% | 0.054 | -0.16 | -0.03 | +0.13 | +0.03 |
| 50% | 0.093 | -0.12 | -0.01 | +0.02 | -0.02 |
| 75% | 0.023 | -0.19 | -0.06 | -0.14 | +0.04 |
| 100% ★ | 0.001 | -0.21 | -0.09 | -0.17 | +0.05 |
| 125% | 0.015 | -0.20 | -0.03 | -0.09 | +0.01 |

- **EmoNet emotion** — ↑ Contentment (+0.53), Relief (+0.36), Concentration (+0.21); ↓ Sexual Lust (-0.35), Malevolence/Malice (-0.34), Anger (-0.22)
- **VoiceNet dimension** — ↑ Mask Resonance (+0.49), Nasal Resonance (+0.40), Oral Resonance (+0.40); ↓ Chest Resonance (-0.82), Perceived Gender (-0.81), Roughness (-0.70)

Merging **Register __low** suppresses the dimension: at the recommended **100%** dose the measured Register score moves from a 0.21 baseline to 0.00 (a -0.21 shift). The dose-response is mostly ordered but noisy between doses. That reach is a real cost — the biggest hit is to **burst-blend** (-0.17); across the board genuineness -0.09, burst-blend -0.17, speech quality +0.05. Emotionally it reads as Contentment (r 0.53), Relief (0.36) and Concentration (0.21), and it moves away from Sexual Lust, Malevolence/Malice and Anger. On other voice dimensions it co-moves most with Mask Resonance (0.49), Nasal Resonance (0.40) and Oral Resonance (0.40), while pulling down Chest Resonance, Perceived Gender and Roughness. Practical call: merge __low at **75–100%**; expect Contentment and Mask Resonance to rise and burst-blend to fall. If you don’t want Contentment bleeding in, offset it with a prompt cue toward Sexual Lust to keep the register shift without the side-effect.
