Purpose: This study uses a voice production model to estimate muscle activation levels and subglottal pressure (P S ) in patients with phonotraumatic vocal hyperfunction (PVH), based on ambulatory measurements of sound level (SPL) spectral tilt (H 1 –H 2 ). In addition, variations these physiological parameters are evaluated respect different values the Daily Phonotrauma Index (DPI). Method: The obtained data from diagnosed PVH matched control group. To infer parameters, were mapped onto...
The ambulatory assessment of vocal function can be significantly enhanced by having access to physiologically based features that describe underlying pathophysiological mechanisms in individuals with voice disorders. This type enhancement improve methods for the prevention, diagnosis, and treatment behaviorally Unfortunately, direct measurement important such as subglottal pressure, fold collision laryngeal muscle activation is impractical laboratory settings. In this study, we introduce a...
Many voice disorders are linked to imbalanced muscle activity and known exhibit asymmetric vocal fold vibration. However, the relation between activation vibration is not well understood. This study introduces an triangular body-cover model of folds, controlled by bilateral intrinsic laryngeal muscles, investigate effects imbalance on oscillation. Various scenarios were considered, encompassing in individual muscles pairs, as accounting for asymmetry lumped element parameters. Measurements...

Phonetically balanced texts are used to study different voice and speech characteristics. In the context of clinical work research, these provide a standard for quantifying perceptual, acoustic, or aerodynamic assessments. Recent modeling efforts being devoted describing long-term behaviors based on collection sustained phonemes. However, comprehensive descriptions phoneme distributions representative connected not readily available. Thus, present introduces method estimate using text data...
