# Chest Resonance — VoiceNet dimension guide

*Category:* Resonance Placement · *code:* `vn_R_CHST` · *slot:* 75

This dimension measures lower-body resonance originating from the chest cavity. 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.** **Chest Resonance** controls lower-body resonance originating from the chest cavity. The **__high** LoRA shifts it +0.49 at 125% (worst cost: burst-blend -0.35); the **__low** LoRA shifts it -0.29 at 50% (worst cost: burst-blend -0.14). The **__high** direction is the stronger, more reliable knob here.

## ▲ HIGH — Chest Resonance __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.324 | — | — | — | — |
| 25% | 0.460 | +0.14 | -0.03 | +0.02 | -0.02 |
| 50% | 0.592 | +0.27 | -0.02 | -0.08 | +0.00 |
| 75% | 0.760 | +0.44 | -0.09 | -0.33 | +0.01 |
| 100% | 0.777 | +0.45 | -0.09 | -0.31 | +0.03 |
| 125% ★ | 0.813 | +0.49 | -0.08 | -0.35 | +0.08 |

- **EmoNet emotion** — ↑ Malevolence/Malice (+0.56), Triumph (+0.53), Pride (+0.45); ↓ Contentment (-0.73), Affection (-0.56), Relief (-0.53)
- **VoiceNet dimension** — ↑ Stance (+0.89), Throat Resonance (+0.84), Attack (+0.83); ↓ Register (-0.85), Vulnerability (-0.71), Casual Style (-0.67)

Merging **Chest Resonance __high** drives the dimension: at the recommended **125%** dose the measured Chest Resonance score moves from a 0.32 baseline to 0.81 (a +0.49 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is a steep cost — the biggest hit is to **burst-blend** (-0.35); across the board genuineness -0.08, burst-blend -0.35, speech quality +0.08. Emotionally it reads as Malevolence/Malice (r 0.56), Triumph (0.53) and Pride (0.45), and it moves away from Contentment, Affection and Relief. On other voice dimensions it co-moves most with Stance (0.89), Throat Resonance (0.84) and Attack (0.83), while pulling down Register, Vulnerability and Casual Style. Practical call: merge __high at **100–125%**; expect Malevolence/Malice and Stance to rise and burst-blend to fall. If you don’t want Malevolence/Malice bleeding in, offset it with a prompt cue toward Contentment to keep the chest resonance shift without the side-effect.

## ▼ LOW — Chest Resonance __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.324 | — | — | — | — |
| 25% | 0.119 | -0.20 | -0.02 | +0.04 | +0.06 |
| 50% ★ | 0.030 | -0.29 | +0.00 | -0.14 | +0.03 |
| 75% | 0.078 | -0.25 | +0.03 | -0.13 | -0.01 |
| 100% | 0.141 | -0.18 | -0.03 | -0.27 | -0.13 |
| 125% | 0.100 | -0.22 | +0.02 | -0.09 | -0.27 |

- **EmoNet emotion** — ↑ Longing (+0.34), Fatigue/Exhaustion (+0.29), Intoxication/Altered States (+0.28); ↓ Contentment (-0.33), Elation (-0.32), Amusement (-0.26)
- **VoiceNet dimension** — ↑ Perceived Gender (+0.89), Throat Resonance (+0.57), Fullness (+0.51); ↓ Register (-0.75), Velocity Flux (-0.56), Playful Style (-0.48)

Merging **Chest Resonance __low** dials back the dimension: at the recommended **50%** dose the measured Chest Resonance score moves from a 0.32 baseline to 0.03 (a -0.29 shift). The dose-response is mostly ordered but noisy between doses. That reach is a modest cost — the biggest hit is to **burst-blend** (-0.14); across the board genuineness +0.00, burst-blend -0.14, speech quality +0.03. Emotionally it reads as Longing (r 0.34), Fatigue/Exhaustion (0.29) and Intoxication/Altered States (0.28), and it moves away from Contentment, Elation and Amusement. On other voice dimensions it co-moves most with Perceived Gender (0.89), Throat Resonance (0.57) and Fullness (0.51), while pulling down Register, Velocity Flux and Playful Style. Practical call: merge __low at **25–75%**; expect Longing and Perceived Gender to rise and burst-blend to fall. If you don’t want Longing bleeding in, offset it with a prompt cue toward Contentment to keep the chest resonance shift without the side-effect.
