# Teacher/Didactic Style — VoiceNet dimension guide

*Category:* Speaking Style · *code:* `vn_S_TECH` · *slot:* 88

This dimension measures how much the voice sounds like a teacher explaining. 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.** **Teacher/Didactic Style** controls how much the voice sounds like a teacher explaining. The **__high** LoRA shifts it +0.25 at 125% (worst cost: burst-blend -0.30); the **__low** LoRA shifts it -0.08 at 25% (worst cost: speech quality -0.07). The **__high** direction is the stronger, more reliable knob here.

## ▲ HIGH — Teacher/Didactic Style __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.214 | — | — | — | — |
| 25% | 0.231 | +0.02 | +0.00 | -0.11 | -0.01 |
| 50% | 0.359 | +0.15 | -0.06 | -0.09 | +0.09 |
| 75% | 0.367 | +0.15 | -0.09 | -0.23 | +0.11 |
| 100% | 0.382 | +0.17 | -0.05 | -0.25 | +0.08 |
| 125% ★ | 0.465 | +0.25 | +0.03 | -0.30 | +0.05 |

- **EmoNet emotion** — ↑ Concentration (+0.62), Emotional Numbness (+0.58), Contemplation (+0.51); ↓ Fear (-0.54), Elation (-0.39), Distress (-0.35)
- **VoiceNet dimension** — ↑ Valence (+0.81), ASMR Style (+0.81), Velocity Flux (+0.79); ↓ Dramatic Style (-0.70), Perceived Gender (-0.66), Cognitive Load (-0.58)

Merging **Teacher/Didactic Style __high** ramps the dimension: at the recommended **125%** dose the measured Teacher/Didactic Style score moves from a 0.21 baseline to 0.47 (a +0.25 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** (-0.30); across the board genuineness +0.03, burst-blend -0.30, speech quality +0.05. Emotionally it reads as Concentration (r 0.62), Emotional Numbness (0.58) and Contemplation (0.51), and it moves away from Fear, Elation and Distress. On other voice dimensions it co-moves most with Valence (0.81), ASMR Style (0.81) and Velocity Flux (0.79), while pulling down Dramatic Style, Perceived Gender and Cognitive Load. Practical call: merge __high at **100–125%**; expect Concentration and Valence to rise and burst-blend to fall. If you don’t want Concentration bleeding in, offset it with a prompt cue toward Fear to keep the teacher/didactic style shift without the side-effect.

## ▼ LOW — Teacher/Didactic Style __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.214 | — | — | — | — |
| 25% ★ | 0.138 | -0.08 | +0.00 | +0.03 | -0.07 |
| 50% | 0.283 | +0.07 | -0.02 | +0.03 | +0.06 |
| 75% | 0.251 | +0.04 | -0.04 | -0.21 | +0.06 |
| 100% | 0.174 | -0.04 | -0.06 | -0.21 | -0.02 |
| 125% | 0.222 | +0.01 | -0.05 | -0.18 | +0.03 |

- **EmoNet emotion** — ↑ Contemplation (+0.52), Concentration (+0.50), Emotional Numbness (+0.47); ↓ Fear (-0.39), Elation (-0.31), Fatigue/Exhaustion (-0.30)
- **VoiceNet dimension** — ↑ ASMR Style (+0.77), Recording Quality (+0.77), Esthetics (+0.68); ↓ Volatility (-0.55), Disfluency (-0.46), Tension (-0.42)

Merging **Teacher/Didactic Style __low** pulls down the dimension: at the recommended **25%** dose the measured Teacher/Didactic Style score moves from a 0.21 baseline to 0.14 (a -0.08 shift). The dose-response is mostly ordered but noisy between doses. That reach is a modest cost — the biggest hit is to **speech quality** (-0.07); across the board genuineness +0.00, burst-blend +0.03, speech quality -0.07. Emotionally it reads as Contemplation (r 0.52), Concentration (0.50) and Emotional Numbness (0.47), and it moves away from Fear, Elation and Fatigue/Exhaustion. On other voice dimensions it co-moves most with ASMR Style (0.77), Recording Quality (0.77) and Esthetics (0.68), while pulling down Volatility, Disfluency and Tension. Practical call: merge __low at **a light 25–50%**; expect Contemplation and ASMR Style to rise and speech quality to fall. If you don’t want Contemplation bleeding in, offset it with a prompt cue toward Fear to keep the teacher/didactic style shift without the side-effect.
