Acoustic markers of emotional expression in professional lyrical singing.
Article in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: This study examines the extent to which induced emotions (joy versus anger) modulate the acoustic architecture of professional lyrical sopranos. Fundamentally aligned with the 4E/5E paradigm of cognitive science, this research aims to analyze the extent to which induced affect reconfigures the vocal system during performance. Grounded in Non-Linear Source-Filter Theory, the study evaluates the functional interaction between glottal source dynamics ( Methods: Three professional Category 2.1 soprano singers underwent an emotional induction protocol using validated film fragments to establish conditions of affective congruence and incongruence while performing selected musical excerpts. Standardized multi-parametric quantitative acoustic tracking was conducted to isolate individual harmonic profiles and verify upper formant configurations. Results: The effective induction of joy fosters resonance optimisation through efficient " Conclusion: These findings suggest that authentic emotional states physically and involuntarily optimise the singer's acoustic output, whereas conflicting affect degrades fine motor technical stability. The results substantiate that classical performance is an enactive process of embodiment, offering key implications for voice pedagogy through explicit parameter modulation training and real-time acoustic feedback systems.
