# Voice Age — VoiceNet dimension guide

*Category:* Speaker Identity · *code:* `vn_AGEV` · *slot:* 52

This dimension measures the perceived biological age and vocal wear of the speaker. 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.** **Voice Age** controls the perceived biological age and vocal wear of the speaker. The **__high** LoRA shifts it +0.21 at 100% (worst cost: burst-blend -0.18); the **__low** LoRA shifts it -0.51 at 125% (worst cost: speech quality -0.28). The **__low** direction is the stronger, more reliable knob here.

## ▲ HIGH — Voice Age __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.643 | — | — | — | — |
| 25% | 0.612 | -0.03 | -0.01 | -0.01 | +0.02 |
| 50% | 0.589 | -0.05 | -0.04 | -0.07 | +0.04 |
| 75% | 0.702 | +0.06 | -0.07 | -0.14 | +0.11 |
| 100% ★ | 0.848 | +0.21 | -0.09 | -0.18 | +0.15 |
| 125% | 0.797 | +0.15 | -0.11 | -0.29 | +0.21 |

- **EmoNet emotion** — ↑ Concentration (+0.38), Emotional Numbness (+0.37), Contemplation (+0.35); ↓ Impatience and Irritability (-0.39), Confusion (-0.36), Pain (-0.34)
- **VoiceNet dimension** — ↑ Whisper-Talk Style (+0.77), Fullness (+0.77), Warmth (+0.69); ↓ Playful Style (-0.53), Dynamic Arc (-0.47), Casual Style (-0.43)

Merging **Voice Age __high** pushes the dimension: at the recommended **100%** dose the measured Voice Age score moves from a 0.64 baseline to 0.85 (a +0.21 shift). The dose-response is mostly ordered but noisy between doses. That reach is a real cost — the biggest hit is to **burst-blend** (-0.18); across the board genuineness -0.09, burst-blend -0.18, speech quality +0.15. Emotionally it reads as Concentration (r 0.38), Emotional Numbness (0.37) and Contemplation (0.35), and it moves away from Impatience and Irritability, Confusion and Pain. On other voice dimensions it co-moves most with Whisper-Talk Style (0.77), Fullness (0.77) and Warmth (0.69), while pulling down Playful Style, Dynamic Arc and Casual Style. Practical call: merge __high at **75–100%**; expect Concentration and Whisper-Talk Style to rise and burst-blend to fall. If you don’t want Concentration bleeding in, offset it with a prompt cue toward Impatience and Irritability to keep the voice age shift without the side-effect.

## ▼ LOW — Voice Age __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.643 | — | — | — | — |
| 25% | 0.542 | -0.10 | +0.02 | -0.06 | +0.03 |
| 50% | 0.468 | -0.17 | -0.01 | -0.17 | -0.06 |
| 75% | 0.348 | -0.29 | -0.01 | -0.20 | -0.11 |
| 100% | 0.163 | -0.48 | +0.09 | -0.08 | -0.34 |
| 125% ★ | 0.132 | -0.51 | +0.00 | -0.19 | -0.28 |

- **EmoNet emotion** — ↑ Interest (+0.75), Affection (+0.66), Longing (+0.66); ↓ Pain (-0.58), Amusement (-0.52), Astonishment/Surprise (-0.45)
- **VoiceNet dimension** — ↑ Fullness (+0.89), Warmth (+0.89), Whisper-Talk Style (+0.87); ↓ Playful Style (-0.82), Dynamic Arc (-0.75), Ranting/Angry Style (-0.67)

Merging **Voice Age __low** lowers the dimension: at the recommended **125%** dose the measured Voice Age score moves from a 0.64 baseline to 0.13 (a -0.51 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** (-0.28); across the board genuineness +0.00, burst-blend -0.19, speech quality -0.28. Emotionally it reads as Interest (r 0.75), Affection (0.66) and Longing (0.66), and it moves away from Pain, Amusement and Astonishment/Surprise. On other voice dimensions it co-moves most with Fullness (0.89), Warmth (0.89) and Whisper-Talk Style (0.87), while pulling down Playful Style, Dynamic Arc and Ranting/Angry Style. Practical call: merge __low at **100–125%**; expect Interest and Fullness to rise and speech quality to fall. If you don’t want Interest bleeding in, offset it with a prompt cue toward Pain to keep the voice age shift without the side-effect.
