Speech and song axes gave positive mean repeat scores for nine voice clips in SEEG and two fMRI cohorts
We tested whether a direction fitted to speech and song keeps repeated differences among nine other human voice clips. The target responses fit neither the axis nor its scale. Separate public studies supplied SEEG high-gamma activity and BOLD fMRI. Two patients and four adults supplied development. A local fixed test used six other patients and 16 other adults. Mean repeat scores were 0.09163 and 0.15908, with pointwise 95% person intervals [0.01714,0.16612] and [0.13927,0.17889]. Five of six patients and all 16 adults had positive scores. The shared mean test passed a fixed two-claim Holm rule, p=0.025041. The shared majority test failed, p=0.109375. The same method in eight adults from a separate fMRI study gave mean 0.07804 [0.03750,0.11858]. A conservative four-claim check gave mean p=0.050082 and did not pass 0.05. A crossed person-and-sound range included zero in SEEG. Added spatial mean removal left the electrical mean interval across zero. One scalar sound gain and one fixed site pattern also gave positive constructed scores. Thus the evidence concerns mean repeat scores in these processed records under the declared two-claim rule. It does not establish transfer to new sounds, a typical patient effect, speaker identity, separate voice sources or a cause. Source selection, separate cohorts, unequal coverage, shared processing and measurement filters limit scope. Code, exact source pins and terms, all positive and negative outcomes, figures, local plans, audits and repeat steps are preserved. Original source arrays stay external.
