Abstract
Background: Several disturbances in speech are present in psychosis; however, the relationship between these disturbances during the first episode of psychosis (FEP) and later vocational functioning is unclear. Demonstrating this relationship is critical if we expect speech and communication deficits to emerge as targets for early intervention.Method: we analyzed three one-minute speech samples using automated speech analysis and Bayes networks in an antipsychotic-naive sample of 39 FEP patients and followed them longitudinally to determine their vocational status (engaged or not engaged in employment education or training - EET vs. NEET) after 6-12 months of treatment. Five linguistic variables with prior evidence of clinical relevance (total and acausal connectives use, pronoun use, analytic thinking, and total words uttered in a limited period) were included in a Bayes network along with longitudinal NEET status and Social and Occupational Functioning Assessment Scale (SOFAS) scores to determine dependencies among our variables. We also included clinical (Positive and Negative Syndrome Scale 8-item version (PANSS-8)), social (parental In review socioeconomic status,) and cognitive features (processing speed) at the time of presentation as covariates.Results: The Bayes network revealed that only total words spoken were directly associated with NEET and had an indirect association with SOFAS, with a second set of dependencies emerging among the remaining linguistic variables. The primary (speech-only) model outperformedmodels including parental socioeconomic status, processing speed or both as latent variables.Conclusion: impoverished speech, even at subclinical levels, may hold prognostic value and warrant clinical consideration when treating first-episode psychosis.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
