# Structure — VoiceNet dimension guide

*Category:* Rhythm & Timing · *code:* `vn_STRU` · *slot:* 47

This dimension measures the macro-level organisation of ideas 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.** **Structure** controls the macro-level organisation of ideas within the clip. The **__high** LoRA shifts it +0.22 at 125% (worst cost: genuineness -0.05); the **__low** LoRA shifts it -0.18 at 100% (worst cost: speech quality -0.27). The **__high** direction is the stronger, more reliable knob here.

## ▲ HIGH — Structure __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.271 | — | — | — | — |
| 25% | 0.348 | +0.08 | -0.02 | +0.06 | +0.05 |
| 50% | 0.372 | +0.10 | -0.05 | +0.01 | +0.09 |
| 75% | 0.411 | +0.14 | -0.05 | -0.01 | +0.12 |
| 100% | 0.489 | +0.22 | -0.06 | -0.05 | +0.10 |
| 125% ★ | 0.494 | +0.22 | -0.05 | -0.02 | +0.15 |

- **EmoNet emotion** — ↑ Contemplation (+0.38), Emotional Numbness (+0.30), Concentration (+0.28); ↓ Fatigue/Exhaustion (-0.49), Helplessness (-0.48), Relief (-0.37)
- **VoiceNet dimension** — ↑ Smoothness (+0.83), Narrator Style (+0.80), Esthetics (+0.80); ↓ Disfluency (-0.77), Genuineness (-0.74), Casual Style (-0.74)

Merging **Structure __high** pushes the dimension: at the recommended **125%** dose the measured Structure score moves from a 0.27 baseline to 0.49 (a +0.22 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is nearly free — the biggest hit is to **genuineness** (-0.05); across the board genuineness -0.05, burst-blend -0.02, speech quality +0.15. Emotionally it reads as Contemplation (r 0.38), Emotional Numbness (0.30) and Concentration (0.28), and it moves away from Fatigue/Exhaustion, Helplessness and Relief. On other voice dimensions it co-moves most with Smoothness (0.83), Narrator Style (0.80) and Esthetics (0.80), while pulling down Disfluency, Genuineness and Casual Style. Practical call: merge __high at **100–125%**; expect Contemplation and Smoothness to rise and genuineness to fall. If you don’t want Contemplation bleeding in, offset it with a prompt cue toward Fatigue/Exhaustion to keep the structure shift without the side-effect.

## ▼ LOW — Structure __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.271 | — | — | — | — |
| 25% | 0.171 | -0.10 | +0.01 | -0.18 | -0.16 |
| 50% | 0.183 | -0.09 | +0.00 | -0.13 | -0.14 |
| 75% | 0.267 | +0.00 | -0.01 | -0.23 | -0.09 |
| 100% ★ | 0.089 | -0.18 | +0.04 | -0.20 | -0.27 |
| 125% | 0.216 | -0.05 | -0.05 | -0.34 | -0.20 |

- **EmoNet emotion** — ↑ Interest (+0.60), Contentment (+0.59), Hope/Enthusiasm/Optimism (+0.58); ↓ Distress (-0.62), Fear (-0.58), Pain (-0.55)
- **VoiceNet dimension** — ↑ Esthetics (+0.84), Recording Quality (+0.84), Smoothness (+0.81); ↓ Disfluency (-0.82), Casual Style (-0.56), Genuineness (-0.53)

Merging **Structure __low** suppresses the dimension: at the recommended **100%** dose the measured Structure score moves from a 0.27 baseline to 0.09 (a -0.18 shift). The dose-response is noisy and non-monotonic — the merge is an unreliable knob here. That reach is a real cost — the biggest hit is to **speech quality** (-0.27); across the board genuineness +0.04, burst-blend -0.20, speech quality -0.27. Emotionally it reads as Interest (r 0.60), Contentment (0.59) and Hope/Enthusiasm/Optimism (0.58), and it moves away from Distress, Fear and Pain. On other voice dimensions it co-moves most with Esthetics (0.84), Recording Quality (0.84) and Smoothness (0.81), while pulling down Disfluency, Casual Style and Genuineness. Practical call: merge __low at **75–100%**; expect Interest and Esthetics to rise and speech quality to fall. If you don’t want Interest bleeding in, offset it with a prompt cue toward Distress to keep the structure shift without the side-effect.
