# Conversational Style — VoiceNet dimension guide

*Category:* Speaking Style · *code:* `vn_S_CONV` · *slot:* 83

This dimension measures how conversational and spontaneous the delivery sounds. 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.** **Conversational Style** controls how conversational and spontaneous the delivery sounds. The **__high** LoRA shifts it +0.12 at 125% (worst cost: burst-blend -0.15); the **__low** LoRA shifts it -0.03 at 125% (worst cost: burst-blend -0.32). The **__high** direction is the stronger, more reliable knob here.

## ▲ HIGH — Conversational Style __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.046 | — | — | — | — |
| 25% | 0.038 | -0.01 | -0.07 | -0.11 | +0.05 |
| 50% | 0.043 | +0.00 | -0.03 | -0.01 | +0.03 |
| 75% | 0.094 | +0.05 | -0.07 | -0.20 | +0.08 |
| 100% | 0.143 | +0.10 | -0.08 | -0.20 | +0.05 |
| 125% ★ | 0.166 | +0.12 | -0.08 | -0.15 | +0.08 |

- **EmoNet emotion** — ↑ Amusement (+0.58), Embarrassment (+0.49), Teasing (+0.43); ↓ Longing (-0.45), Contemplation (-0.36), Interest (-0.35)
- **VoiceNet dimension** — ↑ Dynamic Arc (+0.74), Arousal Shift (+0.62), Playful Style (+0.62); ↓ Vocal-burst blend (-0.40), Cognitive Load (-0.40), Whisper-Talk Style (-0.25)

Merging **Conversational Style __high** raises the dimension: at the recommended **125%** dose the measured Conversational Style score moves from a 0.05 baseline to 0.17 (a +0.12 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is a modest cost — the biggest hit is to **burst-blend** (-0.15); across the board genuineness -0.08, burst-blend -0.15, speech quality +0.08. Emotionally it reads as Amusement (r 0.58), Embarrassment (0.49) and Teasing (0.43), and it moves away from Longing, Contemplation and Interest. On other voice dimensions it co-moves most with Dynamic Arc (0.74), Arousal Shift (0.62) and Playful Style (0.62), while pulling down Vocal-burst blend, Cognitive Load and Whisper-Talk Style. Practical call: merge __high at **100–125%**; expect Amusement and Dynamic Arc to rise and burst-blend to fall. If you don’t want Amusement bleeding in, offset it with a prompt cue toward Longing to keep the conversational style shift without the side-effect.

## ▼ LOW — Conversational Style __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.046 | — | — | — | — |
| 25% | 0.021 | -0.03 | +0.02 | +0.16 | +0.00 |
| 50% | 0.044 | +0.00 | -0.04 | -0.07 | +0.04 |
| 75% | 0.021 | -0.02 | -0.05 | -0.15 | +0.03 |
| 100% | 0.124 | +0.08 | +0.01 | -0.17 | +0.00 |
| 125% ★ | 0.013 | -0.03 | -0.06 | -0.32 | -0.04 |

- **EmoNet emotion** — ↑ Concentration (+0.17), Embarrassment (+0.16), Emotional Numbness (+0.14); ↓ Interest (-0.41), Longing (-0.38), Affection (-0.37)
- **VoiceNet dimension** — ↑ Playful Style (+0.55), Casual Style (+0.52), Content Appropriateness (3-point Scale) (+0.51); ↓ Monologue Style (-0.52), Narrator Style (-0.50), Formal Style (-0.46)

Merging **Conversational Style __low** pulls down the dimension: at the recommended **125%** dose the measured Conversational Style score moves from a 0.05 baseline to 0.01 (a -0.03 shift). The dose-response is mostly ordered but noisy between doses. That reach is a steep cost — the biggest hit is to **burst-blend** (-0.32); across the board genuineness -0.06, burst-blend -0.32, speech quality -0.04. Emotionally it reads as Concentration (r 0.17), Embarrassment (0.16) and Emotional Numbness (0.14), and it moves away from Interest, Longing and Affection. On other voice dimensions it co-moves most with Playful Style (0.55), Casual Style (0.52) and Content Appropriateness (3-point Scale) (0.51), while pulling down Monologue Style, Narrator Style and Formal Style. Practical call: merge __low at **100–125%**; expect Concentration and Playful Style to rise and burst-blend to fall. If you don’t want Concentration bleeding in, offset it with a prompt cue toward Interest to keep the conversational style shift without the side-effect.
