# Articulation Clarity — VoiceNet dimension guide

*Category:* Rhythm & Timing · *code:* `vn_CLRT` · *slot:* 43

This dimension measures the precision with which consonants and vowels are produced. 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.** **Articulation Clarity** controls the precision with which consonants and vowels are produced. The **__high** LoRA shifts it +0.34 at 125% (worst cost: burst-blend -0.25); the **__low** LoRA shifts it -0.19 at 75% (worst cost: speech quality -0.37). The **__high** direction is the stronger, more reliable knob here.

## ▲ HIGH — Articulation Clarity __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.207 | — | — | — | — |
| 25% | 0.249 | +0.04 | -0.03 | +0.02 | +0.08 |
| 50% | 0.355 | +0.15 | -0.04 | -0.06 | +0.06 |
| 75% | 0.454 | +0.25 | -0.11 | -0.22 | +0.12 |
| 100% | 0.488 | +0.28 | -0.10 | -0.26 | +0.11 |
| 125% ★ | 0.552 | +0.34 | -0.11 | -0.25 | +0.13 |

- **EmoNet emotion** — ↑ Triumph (+0.30), Pride (+0.25), Malevolence/Malice (+0.21); ↓ Relief (-0.57), Fatigue/Exhaustion (-0.56), Helplessness (-0.49)
- **VoiceNet dimension** — ↑ Attack (+0.83), Harmonicity (+0.82), Metallic Character (+0.80); ↓ Vulnerability (-0.83), Disfluency (-0.79), Casual Style (-0.75)

Merging **Articulation Clarity __high** pushes the dimension: at the recommended **125%** dose the measured Articulation Clarity score moves from a 0.21 baseline to 0.55 (a +0.34 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is a real cost — the biggest hit is to **burst-blend** (-0.25); across the board genuineness -0.11, burst-blend -0.25, speech quality +0.13. Emotionally it reads as Triumph (r 0.30), Pride (0.25) and Malevolence/Malice (0.21), and it moves away from Relief, Fatigue/Exhaustion and Helplessness. On other voice dimensions it co-moves most with Attack (0.83), Harmonicity (0.82) and Metallic Character (0.80), while pulling down Vulnerability, Disfluency and Casual Style. Practical call: merge __high at **100–125%**; expect Triumph and Attack to rise and burst-blend to fall. If you don’t want Triumph bleeding in, offset it with a prompt cue toward Relief to keep the articulation clarity shift without the side-effect.

## ▼ LOW — Articulation Clarity __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.207 | — | — | — | — |
| 25% | 0.173 | -0.03 | +0.02 | +0.02 | -0.04 |
| 50% | 0.033 | -0.17 | +0.06 | -0.03 | -0.22 |
| 75% ★ | 0.017 | -0.19 | +0.10 | -0.12 | -0.37 |
| 100% | 0.117 | -0.09 | +0.08 | -0.11 | -0.34 |
| 125% | 0.134 | -0.07 | +0.05 | -0.19 | -0.33 |

- **EmoNet emotion** — ↑ Hope/Enthusiasm/Optimism (+0.72), Interest (+0.61), Affection (+0.49); ↓ Fatigue/Exhaustion (-0.60), Sadness (-0.49), Pain (-0.46)
- **VoiceNet dimension** — ↑ Harmonicity (+0.74), Emphasis (+0.69), Storytelling Style (+0.68); ↓ Genuineness (-0.67), Disfluency (-0.60), Vulnerability (-0.50)

Merging **Articulation Clarity __low** damps the dimension: at the recommended **75%** dose the measured Articulation Clarity score moves from a 0.21 baseline to 0.02 (a -0.19 shift). The dose-response is mostly ordered but noisy between doses. That reach is a steep cost — the biggest hit is to **speech quality** (-0.37); across the board genuineness +0.10, burst-blend -0.12, speech quality -0.37. Emotionally it reads as Hope/Enthusiasm/Optimism (r 0.72), Interest (0.61) and Affection (0.49), and it moves away from Fatigue/Exhaustion, Sadness and Pain. On other voice dimensions it co-moves most with Harmonicity (0.74), Emphasis (0.69) and Storytelling Style (0.68), while pulling down Genuineness, Disfluency and Vulnerability. Practical call: merge __low at **50–100%**; expect Hope/Enthusiasm/Optimism and Harmonicity to rise and speech quality to fall. If you don’t want Hope/Enthusiasm/Optimism bleeding in, offset it with a prompt cue toward Fatigue/Exhaustion to keep the articulation clarity shift without the side-effect.
