# Volatility — VoiceNet dimension guide

*Category:* Emotion & Affect · *code:* `vn_VOLT` · *slot:* 56

This dimension measures how much the emotional state shifts or vibrates within the clip. 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.** **Volatility** controls how much the emotional state shifts or vibrates within the clip. The **__high** LoRA shifts it +0.28 at 125% (worst cost: speech quality -0.37); the **__low** LoRA shifts it -0.15 at 75% (worst cost: burst-blend -0.12). The **__high** direction is the stronger, more reliable knob here.

## ▲ HIGH — Volatility __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.398 | — | — | — | — |
| 25% | 0.420 | +0.02 | -0.04 | -0.12 | +0.03 |
| 50% | 0.583 | +0.19 | +0.00 | -0.14 | -0.11 |
| 75% | 0.607 | +0.21 | -0.03 | -0.33 | -0.22 |
| 100% | 0.602 | +0.20 | -0.04 | -0.28 | -0.21 |
| 125% ★ | 0.676 | +0.28 | +0.02 | -0.12 | -0.37 |

- **EmoNet emotion** — ↑ Triumph (+0.59), Anger (+0.57), Impatience and Irritability (+0.53); ↓ Contemplation (-0.64), Affection (-0.58), Concentration (-0.51)
- **VoiceNet dimension** — ↑ Dramatic Style (+0.82), Dynamic Arc (+0.78), Arousal (+0.77); ↓ Warmth (-0.82), Monologue Style (-0.78), Whisper-Talk Style (-0.77)

Merging **Volatility __high** drives the dimension: at the recommended **125%** dose the measured Volatility score moves from a 0.40 baseline to 0.68 (a +0.28 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 **speech quality** (-0.37); across the board genuineness +0.02, burst-blend -0.12, speech quality -0.37. Emotionally it reads as Triumph (r 0.59), Anger (0.57) and Impatience and Irritability (0.53), and it moves away from Contemplation, Affection and Concentration. On other voice dimensions it co-moves most with Dramatic Style (0.82), Dynamic Arc (0.78) and Arousal (0.77), while pulling down Warmth, Monologue Style and Whisper-Talk Style. Practical call: merge __high at **100–125%**; expect Triumph and Dramatic Style to rise and speech quality to fall. If you don’t want Triumph bleeding in, offset it with a prompt cue toward Contemplation to keep the volatility shift without the side-effect.

## ▼ LOW — Volatility __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.398 | — | — | — | — |
| 25% | 0.328 | -0.07 | -0.04 | +0.03 | +0.07 |
| 50% | 0.330 | -0.07 | -0.08 | -0.09 | +0.12 |
| 75% ★ | 0.248 | -0.15 | -0.09 | -0.12 | +0.14 |
| 100% | 0.286 | -0.11 | -0.13 | -0.19 | +0.15 |
| 125% | 0.255 | -0.14 | -0.06 | -0.14 | +0.13 |

- **EmoNet emotion** — ↑ Jealousy & Envy (+0.37), Doubt (+0.36), Elation (+0.36); ↓ Emotional Numbness (-0.43), Contemplation (-0.39), Embarrassment (-0.29)
- **VoiceNet dimension** — ↑ Casual Style (+0.71), Respiration (+0.61), Genuineness (+0.55); ↓ Valence Shift (-0.75), Structure (-0.69), Teacher/Didactic Style (-0.67)

Merging **Volatility __low** suppresses the dimension: at the recommended **75%** dose the measured Volatility score moves from a 0.40 baseline to 0.25 (a -0.15 shift). The dose-response is monotonic but it saturates early, so higher doses add little. That reach is a modest cost — the biggest hit is to **burst-blend** (-0.12); across the board genuineness -0.09, burst-blend -0.12, speech quality +0.14. Emotionally it reads as Jealousy & Envy (r 0.37), Doubt (0.36) and Elation (0.36), and it moves away from Emotional Numbness, Contemplation and Embarrassment. On other voice dimensions it co-moves most with Casual Style (0.71), Respiration (0.61) and Genuineness (0.55), while pulling down Valence Shift, Structure and Teacher/Didactic Style. Practical call: merge __low at **50–100%**; expect Jealousy & Envy and Casual Style to rise and burst-blend to fall. If you don’t want Jealousy & Envy bleeding in, offset it with a prompt cue toward Emotional Numbness to keep the volatility shift without the side-effect.
