Valence VoiceNet dimension guide
Emotion & Affectcode vn_VALNslot 54
This dimension measures the global emotional polarity of the performance. Below: the merge-scaling dose-response for the __high and __low LoRA (laion/moss-voicenet-dimension-loras) at 25/50/75/100/125%, the measured target value at each dose, the top-3 ± correlated EmoNet emotions and VoiceNet dimensions, three audio samples per dose, and a grounded prompting tip. Costs are shifts vs. the 24-sample neutral baseline in genuineness, vocal-burst blend and speech quality.
Valence controls the global emotional polarity of the performance. The __high LoRA shifts it +0.24 at 125% (worst cost: burst-blend -0.29); the __low LoRA shifts it -0.01 at 25% (worst cost: burst-blend -0.06). The __high direction is the stronger, more reliable knob here.

Merging Valence __high ramps the dimension: at the recommended 125% dose the measured Valence score moves from a 0.08 baseline to 0.31 (a +0.24 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 (-0.29); across the board genuineness +0.02, burst-blend -0.29, speech quality +0.04. Emotionally it reads as Emotional Numbness (r 0.44), Concentration (0.35) and Contentment (0.20), and it moves away from Interest, Fear and Malevolence/Malice. On other voice dimensions it co-moves most with Nasal Resonance (0.73), Head Resonance (0.71) and Conversational Style (0.71), while pulling down Perceived Gender, Cartoonish Style and Dramatic Style. Practical call: merge __high at 100–125%; expect Emotional Numbness and Nasal Resonance to rise and burst-blend to fall. If you don’t want Emotional Numbness bleeding in, offset it with a prompt cue toward Interest to keep the valence shift without the side-effect.

Merging Valence __low pulls down the dimension: at the recommended 25% dose the measured Valence score moves from a 0.08 baseline to 0.07 (a -0.01 shift). The dose-response is noisy and non-monotonic — the merge is an unreliable knob here. That reach is nearly free — the biggest hit is to burst-blend (-0.06); across the board genuineness -0.03, burst-blend -0.06, speech quality +0.02. Emotionally it reads as Amusement (r 0.39), Teasing (0.38) and Emotional Numbness (0.19), and it moves away from Awe, Fear and Infatuation. On other voice dimensions it co-moves most with Head Resonance (0.78), Brightness (0.78) and Mask Resonance (0.77), while pulling down Cognitive Load, Disfluency and Perceived Gender. Practical call: merge __low at a light 25–50%; expect Amusement and Head Resonance to rise and burst-blend to fall. If you don’t want Amusement bleeding in, offset it with a prompt cue toward Awe to keep the valence shift without the side-effect.
