Arousal VoiceNet dimension guide
Emotion & Affectcode vn_AROUslot 55
This dimension measures the physiological “engine speed” of the speaker. 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 controls the physiological “engine speed” of the speaker. The __high LoRA shifts it +0.73 at 100% (worst cost: burst-blend -0.43); the __low LoRA shifts it -0.09 at 50% (worst cost: burst-blend -0.23). The __high direction is the stronger, more reliable knob here.

Merging Arousal __high ramps the dimension: at the recommended 100% dose the measured Arousal score moves from a 0.14 baseline to 0.87 (a +0.73 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 (-0.43); across the board genuineness -0.08, burst-blend -0.43, speech quality -0.23. Emotionally it reads as Triumph (r 0.72), Anger (0.68) and Bitterness (0.61), and it moves away from Contemplation, Relief and Contentment. On other voice dimensions it co-moves most with Attack (0.98), Metallic Character (0.98) and Stance (0.94), while pulling down Vulnerability, Whisper-Talk Style and Warmth. 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 Contemplation to keep the arousal shift without the side-effect.

Merging Arousal __low damps the dimension: at the recommended 50% dose the measured Arousal score moves from a 0.14 baseline to 0.06 (a -0.09 shift). The dose-response is mostly ordered but noisy between doses. That reach is a real cost — the biggest hit is to burst-blend (-0.23); across the board genuineness -0.01, burst-blend -0.23, speech quality -0.07. Emotionally it reads as Jealousy & Envy (r 0.58), Teasing (0.54) and Bitterness (0.35), and it moves away from Sourness, Fatigue/Exhaustion and Contentment. On other voice dimensions it co-moves most with Metallic Character (0.82), Attack (0.73) and Stance (0.72), while pulling down Conversational Style, Vulnerability and ASMR Style. Practical call: merge __low at 25–75%; expect Jealousy & Envy and Metallic Character to rise and burst-blend to fall. If you don’t want Jealousy & Envy bleeding in, offset it with a prompt cue toward Sourness to keep the arousal shift without the side-effect.
