Chunking VoiceNet dimension guide
Rhythm & Timingcode vn_CHNKslot 41
This dimension measures how words are grouped into breath units and how often the speaker pauses. 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.
Chunking controls how words are grouped into breath units and how often the speaker pauses. The __high LoRA shifts it +0.28 at 125% (worst cost: burst-blend -0.22); the __low LoRA shifts it +0.00 at 50% (worst cost: burst-blend -0.15). The __high direction is the stronger, more reliable knob here.

Merging Chunking __high raises the dimension: at the recommended 125% dose the measured Chunking score moves from a 0.16 baseline to 0.43 (a +0.28 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 (-0.22); across the board genuineness -0.06, burst-blend -0.22, speech quality +0.04. Emotionally it reads as Hope/Enthusiasm/Optimism (r 0.40), Elation (0.27) and Amusement (0.18), and it moves away from Helplessness, Awe and Fear. On other voice dimensions it co-moves most with Brightness (0.90), Arousal Shift (0.80) and Smoothness (0.79), while pulling down Cognitive Load, Disfluency and Vulnerability. Practical call: merge __high at 100–125%; expect Hope/Enthusiasm/Optimism and Brightness to rise and burst-blend to fall. If you don’t want Hope/Enthusiasm/Optimism bleeding in, offset it with a prompt cue toward Helplessness to keep the chunking shift without the side-effect.

Merging Chunking __low lowers the dimension: at the recommended 50% dose the measured Chunking score moves from a 0.16 baseline to 0.16 (a +0.00 shift). The dose-response is mostly ordered but noisy between doses. That reach is a modest cost — the biggest hit is to burst-blend (-0.15); across the board genuineness +0.00, burst-blend -0.15, speech quality -0.10. Emotionally it reads as Concentration (r 0.28), Sourness (0.25) and Bitterness (0.25), and it moves away from Pain, Fatigue/Exhaustion and Sadness. On other voice dimensions it co-moves most with Brightness (0.76), Arousal Shift (0.75) and Structure (0.71), while pulling down Disfluency, Vulnerability and Genuineness. Practical call: merge __low at 25–75%; expect Concentration and Brightness to rise and burst-blend to fall. If you don’t want Concentration bleeding in, offset it with a prompt cue toward Pain to keep the chunking shift without the side-effect.
