# Respiration — VoiceNet dimension guide

*Category:* Physical Production · *code:* `vn_RESP` · *slot:* 57

This dimension measures the audibility and laboriousness of breathing. 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.** **Respiration** controls the audibility and laboriousness of breathing. The **__high** LoRA shifts it +0.16 at 100% (worst cost: speech quality -0.29); the **__low** LoRA shifts it -0.24 at 125% (worst cost: burst-blend -0.36). The **__low** direction is the stronger, more reliable knob here.

## ▲ HIGH — Respiration __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.442 | — | — | — | — |
| 25% | 0.497 | +0.05 | -0.02 | -0.10 | -0.07 |
| 50% | 0.460 | +0.02 | -0.01 | -0.12 | -0.06 |
| 75% | 0.533 | +0.09 | +0.04 | -0.13 | -0.15 |
| 100% ★ | 0.598 | +0.16 | +0.05 | -0.23 | -0.29 |
| 125% | 0.533 | +0.09 | -0.01 | -0.25 | -0.30 |

- **EmoNet emotion** — ↑ Amusement (+0.49), Fatigue/Exhaustion (+0.39), Teasing (+0.38); ↓ Contemplation (-0.69), Affection (-0.44), Contentment (-0.42)
- **VoiceNet dimension** — ↑ Casual Style (+0.71), Volatility (+0.67), Disfluency (+0.63); ↓ Structure (-0.66), Recording Quality (-0.62), Formal Style (-0.61)

Merging **Respiration __high** pushes the dimension: at the recommended **100%** dose the measured Respiration score moves from a 0.44 baseline to 0.60 (a +0.16 shift). The dose-response is mostly ordered but noisy between doses. That reach is a steep cost — the biggest hit is to **speech quality** (-0.29); across the board genuineness +0.05, burst-blend -0.23, speech quality -0.29. Emotionally it reads as Amusement (r 0.49), Fatigue/Exhaustion (0.39) and Teasing (0.38), and it moves away from Contemplation, Affection and Contentment. On other voice dimensions it co-moves most with Casual Style (0.71), Volatility (0.67) and Disfluency (0.63), while pulling down Structure, Recording Quality and Formal Style. Practical call: merge __high at **75–100%**; expect Amusement and Casual Style to rise and speech quality to fall. If you don’t want Amusement bleeding in, offset it with a prompt cue toward Contemplation to keep the respiration shift without the side-effect.

## ▼ LOW — Respiration __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.442 | — | — | — | — |
| 25% | 0.374 | -0.07 | -0.05 | -0.03 | +0.05 |
| 50% | 0.337 | -0.11 | -0.04 | -0.19 | +0.06 |
| 75% | 0.366 | -0.08 | -0.10 | -0.24 | +0.05 |
| 100% | 0.355 | -0.09 | -0.12 | -0.30 | +0.12 |
| 125% ★ | 0.207 | -0.24 | -0.12 | -0.36 | +0.08 |

- **EmoNet emotion** — ↑ Fatigue/Exhaustion (+0.39), Anger (+0.39), Fear (+0.35); ↓ Emotional Numbness (-0.45), Concentration (-0.20), Contemplation (-0.19)
- **VoiceNet dimension** — ↑ Genuineness (+0.62), Disfluency (+0.60), Volatility (+0.60); ↓ Newsreader Style (-0.65), Formal Style (-0.58), Structure (-0.57)

Merging **Respiration __low** damps the dimension: at the recommended **125%** dose the measured Respiration score moves from a 0.44 baseline to 0.21 (a -0.24 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 -0.12, burst-blend -0.36, speech quality +0.08. Emotionally it reads as Fatigue/Exhaustion (r 0.39), Anger (0.39) and Fear (0.35), and it moves away from Emotional Numbness, Concentration and Contemplation. On other voice dimensions it co-moves most with Genuineness (0.62), Disfluency (0.60) and Volatility (0.60), while pulling down Newsreader Style, Formal Style and Structure. Practical call: merge __low at **100–125%**; expect Fatigue/Exhaustion and Genuineness to rise and burst-blend to fall. If you don’t want Fatigue/Exhaustion bleeding in, offset it with a prompt cue toward Emotional Numbness to keep the respiration shift without the side-effect.
