# Vulnerability — VoiceNet dimension guide

*Category:* Social & Interpersonal · *code:* `vn_VULN` · *slot:* 50

This dimension measures the perceived openness or permeability of the speaker. 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.** **Vulnerability** controls the perceived openness or permeability of the speaker. The **__high** LoRA shifts it +0.05 at 125% (worst cost: burst-blend -0.26); the **__low** LoRA shifts it -0.40 at 125% (worst cost: burst-blend -0.36). The **__low** direction is the stronger, more reliable knob here.

## ▲ HIGH — Vulnerability __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.523 | — | — | — | — |
| 25% | 0.573 | +0.05 | +0.04 | +0.03 | +0.04 |
| 50% | 0.512 | -0.01 | -0.01 | -0.03 | +0.04 |
| 75% | 0.556 | +0.03 | +0.01 | -0.08 | +0.00 |
| 100% | 0.543 | +0.02 | +0.06 | +0.03 | -0.11 |
| 125% ★ | 0.575 | +0.05 | -0.01 | -0.26 | -0.07 |

- **EmoNet emotion** — ↑ Pain (+0.54), Helplessness (+0.42), Sadness (+0.36); ↓ Triumph (-0.42), Amusement (-0.41), Impatience and Irritability (-0.40)
- **VoiceNet dimension** — ↑ Disfluency (+0.45), Respiration (+0.44), Conversational Style (+0.38); ↓ Arousal Shift (-0.56), Harmonicity (-0.55), Stance (-0.49)

Merging **Vulnerability __high** raises the dimension: at the recommended **125%** dose the measured Vulnerability score moves from a 0.52 baseline to 0.57 (a +0.05 shift). The dose-response is mostly ordered but noisy between doses. That reach is a real cost — the biggest hit is to **burst-blend** (-0.26); across the board genuineness -0.01, burst-blend -0.26, speech quality -0.07. Emotionally it reads as Pain (r 0.54), Helplessness (0.42) and Sadness (0.36), and it moves away from Triumph, Amusement and Impatience and Irritability. On other voice dimensions it co-moves most with Disfluency (0.45), Respiration (0.44) and Conversational Style (0.38), while pulling down Arousal Shift, Harmonicity and Stance. Practical call: merge __high at **100–125%**; expect Pain and Disfluency to rise and burst-blend to fall. If you don’t want Pain bleeding in, offset it with a prompt cue toward Triumph to keep the vulnerability shift without the side-effect.

## ▼ LOW — Vulnerability __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.523 | — | — | — | — |
| 25% | 0.465 | -0.06 | -0.01 | -0.04 | +0.05 |
| 50% | 0.438 | -0.08 | -0.04 | -0.25 | -0.02 |
| 75% | 0.136 | -0.39 | -0.09 | -0.43 | -0.04 |
| 100% | 0.164 | -0.36 | -0.07 | -0.41 | -0.14 |
| 125% ★ | 0.128 | -0.40 | -0.05 | -0.36 | -0.24 |

- **EmoNet emotion** — ↑ Contemplation (+0.64), Relief (+0.64), Contentment (+0.55); ↓ Triumph (-0.72), Malevolence/Malice (-0.57), Pride (-0.57)
- **VoiceNet dimension** — ↑ Cognitive Load (+0.67), ASMR Style (+0.66), Whisper-Talk Style (+0.62); ↓ Harmonicity (-0.85), Authoritative Style (-0.85), Stance (-0.85)

Merging **Vulnerability __low** damps the dimension: at the recommended **125%** dose the measured Vulnerability score moves from a 0.52 baseline to 0.13 (a -0.40 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** (-0.36); across the board genuineness -0.05, burst-blend -0.36, speech quality -0.24. Emotionally it reads as Contemplation (r 0.64), Relief (0.64) and Contentment (0.55), and it moves away from Triumph, Malevolence/Malice and Pride. On other voice dimensions it co-moves most with Cognitive Load (0.67), ASMR Style (0.66) and Whisper-Talk Style (0.62), while pulling down Harmonicity, Authoritative Style and Stance. Practical call: merge __low at **100–125%**; expect Contemplation and Cognitive Load to rise and burst-blend to fall. If you don’t want Contemplation bleeding in, offset it with a prompt cue toward Triumph to keep the vulnerability shift without the side-effect.
