At selected sites, four nonvocal axes captured extra speech-and-song repeat energy in six SEEG patients and 24 fMRI adults

We tested transfer of auditory response directions in separate public human studies. Four axes were fitted only to 128 source nonvocal sounds. Two other repeats tested 28 speech-and-song sounds. Target and spatial means were removed. Twenty fixed 16-site panels gave one score per person. Development used two SEEG patients and four fMRI adults. Reserved tests used six patients and 24 adults from two fMRI studies. Mean energy gains above the rank-four isotropic reference were 6.3659%, 8.9741% and 10.0267% of measured target energy. Their 95% person intervals were positive. All 30 people had positive scores. The stronger half-energy contrast was uncertain in SEEG, with three of six positive patients. The shared alignment rule passed after two-claim Holm correction, p=0.03125. The half-energy rule failed, p=0.65625. Common target-sound and person resampling kept positive alignment ranges. The assay uses separate person spaces and requires evidence in each cohort. Source selection used full sound panels and repeats. It can break the assumptions needed to infer latent signal energy. Constructed examples gave transfer with stable nuisance or disjoint neural sources under a common measurement map. Thus the result concerns selected processed responses. It does not establish shared neurons, neural rank or a cause. The package gives code, source versions and terms, plans, all outcomes, figures and repeat instructions. Original neural arrays remain external.
