Arousal Shift VoiceNet dimension guide
Temporal Dynamicscode vn_ARSHslot 70
This dimension measures the change in physiological activation over the clip. 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.
Arousal Shift controls the change in physiological activation over the clip. The __high LoRA shifts it +0.43 at 100% (worst cost: burst-blend -0.35); the __low LoRA shifts it -0.14 at 125% (worst cost: speech quality -0.34). The __high direction is the stronger, more reliable knob here.

Merging Arousal Shift __high raises the dimension: at the recommended 100% dose the measured Arousal Shift score moves from a 0.20 baseline to 0.64 (a +0.43 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 (-0.35); across the board genuineness -0.10, burst-blend -0.35, speech quality +0.01. Emotionally it reads as Triumph (r 0.63), Pride (0.61) and Anger (0.48), and it moves away from Relief, Affection and Longing. On other voice dimensions it co-moves most with Attack (0.89), Arousal (0.89) and Stance (0.86), while pulling down Vulnerability, Cognitive Load and Genuineness. Practical call: merge __high at 75–100%; 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 arousal shift shift without the side-effect.

Merging Arousal Shift __low damps the dimension: at the recommended 125% dose the measured Arousal Shift score moves from a 0.20 baseline to 0.06 (a -0.14 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 (-0.34); across the board genuineness +0.07, burst-blend -0.11, speech quality -0.34. Emotionally it reads as Interest (r 0.72), Affection (0.61) and Hope/Enthusiasm/Optimism (0.58), and it moves away from Pain, Fatigue/Exhaustion and Disappointment. On other voice dimensions it co-moves most with Structure (0.76), Smoothness (0.75) and Fullness (0.73), while pulling down Genuineness, Disfluency and Playful Style. Practical call: merge __low at 100–125%; expect Interest and Structure 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 arousal shift shift without the side-effect.
