# Warmth — VoiceNet dimension guide

*Category:* Spectral & Timbral · *code:* `vn_WARM` · *slot:* 65

This dimension measures the emphasis on low-mid frequencies (~200–500 Hz). 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.** **Warmth** controls the emphasis on low-mid frequencies (~200–500 Hz). The **__high** LoRA shifts it +0.16 at 125% (worst cost: burst-blend -0.13); the **__low** LoRA shifts it -0.57 at 125% (worst cost: speech quality -0.33). The **__low** direction is the stronger, more reliable knob here.

## ▲ HIGH — Warmth __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.673 | — | — | — | — |
| 25% | 0.718 | +0.04 | -0.02 | +0.06 | +0.07 |
| 50% | 0.742 | +0.07 | -0.04 | -0.08 | +0.10 |
| 75% | 0.726 | +0.05 | -0.06 | -0.05 | +0.12 |
| 100% | 0.700 | +0.03 | -0.09 | -0.17 | +0.13 |
| 125% ★ | 0.830 | +0.16 | -0.07 | -0.13 | +0.19 |

- **EmoNet emotion** — ↑ Contemplation (+0.43), Emotional Numbness (+0.34), Sexual Lust (+0.23); ↓ Doubt (-0.52), Impatience and Irritability (-0.41), Anger (-0.37)
- **VoiceNet dimension** — ↑ Whisper-Talk Style (+0.86), Recording Quality (+0.74), Monologue Style (+0.73); ↓ Dynamic Arc (-0.70), Ranting/Angry Style (-0.69), Playful Style (-0.67)

Merging **Warmth __high** pushes the dimension: at the recommended **125%** dose the measured Warmth score moves from a 0.67 baseline to 0.83 (a +0.16 shift). The dose-response is mostly ordered but noisy between doses. That reach is a modest cost — the biggest hit is to **burst-blend** (-0.13); across the board genuineness -0.07, burst-blend -0.13, speech quality +0.19. Emotionally it reads as Contemplation (r 0.43), Emotional Numbness (0.34) and Sexual Lust (0.23), and it moves away from Doubt, Impatience and Irritability and Anger. On other voice dimensions it co-moves most with Whisper-Talk Style (0.86), Recording Quality (0.74) and Monologue Style (0.73), while pulling down Dynamic Arc, Ranting/Angry Style and Playful Style. Practical call: merge __high at **100–125%**; expect Contemplation and Whisper-Talk Style to rise and burst-blend to fall. If you don’t want Contemplation bleeding in, offset it with a prompt cue toward Doubt to keep the warmth shift without the side-effect.

## ▼ LOW — Warmth __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.673 | — | — | — | — |
| 25% | 0.660 | -0.01 | -0.02 | -0.05 | +0.05 |
| 50% | 0.493 | -0.18 | -0.03 | -0.29 | -0.01 |
| 75% | 0.345 | -0.33 | +0.01 | -0.21 | -0.12 |
| 100% | 0.114 | -0.56 | -0.01 | -0.22 | -0.32 |
| 125% ★ | 0.108 | -0.57 | +0.03 | -0.26 | -0.33 |

- **EmoNet emotion** — ↑ Contemplation (+0.79), Contentment (+0.69), Interest (+0.63); ↓ Astonishment/Surprise (-0.64), Pain (-0.60), Anger (-0.57)
- **VoiceNet dimension** — ↑ Whisper-Talk Style (+0.93), Recording Quality (+0.88), Monologue Style (+0.88); ↓ Arousal (-0.86), Playful Style (-0.85), Dynamic Arc (-0.83)

Merging **Warmth __low** lowers the dimension: at the recommended **125%** dose the measured Warmth score moves from a 0.67 baseline to 0.11 (a -0.57 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** (-0.33); across the board genuineness +0.03, burst-blend -0.26, speech quality -0.33. Emotionally it reads as Contemplation (r 0.79), Contentment (0.69) and Interest (0.63), and it moves away from Astonishment/Surprise, Pain and Anger. On other voice dimensions it co-moves most with Whisper-Talk Style (0.93), Recording Quality (0.88) and Monologue Style (0.88), while pulling down Arousal, Playful Style and Dynamic Arc. Practical call: merge __low at **100–125%**; expect Contemplation and Whisper-Talk Style to rise and speech quality to fall. If you don’t want Contemplation bleeding in, offset it with a prompt cue toward Astonishment/Surprise to keep the warmth shift without the side-effect.
