A Comparison of Voice Amplifiers and Personal Communication Systems for Hypophonia: An Exploration of Communicative Participation
Bibliographic record
Abstract
PURPOSE: The primary purpose of this study was to evaluate how individuals with hypophonia (HP; also referred to as HP participants) and their primary communication partners (PCPs; also referred to as PCP participants) rate communicative participation before and after experience with a speech amplification device. A secondary purpose was to evaluate pre- and post-device effects on self-rated communicative participation for each of the three speech amplification devices trialed outside of the laboratory. METHOD: Seventeen individuals with HP and their PCPs participated in a crossover design study that compared three different amplification devices: a wired belt-pack amplifier, a wireless stationary amplifier, and a personal frequency modulation (FM) system. Both the individuals with HP and their PCPs self-rated communicative participation at baseline and after trialing each device following 1-week device trial periods at home. Patient-reported outcome measures included the Communicative Effectiveness Survey (CES) and the Voice Activity and Participation Profile (VAPP). Following study completion, participants indicated whether they would like to select a specific device to continue using. RESULTS: Overall, HP participants rated communicative participation following device use higher than that in the pre-device condition, with the FM system resulting in the overall highest VAPP ratings and second highest CES ratings. Furthermore, HP and PCP participants rated these measures similarly. Finally, HP participants who selected a device to continue using self-reported lower total communicative effectiveness scores and greater voice activity limitations and participation restrictions at baseline in comparison to the nonselectors. CONCLUSIONS: This study contributes to an increased understanding of how communicative participation is experienced within this clinical population resulting from speech amplification. It is suggested that the inclusion of participation-based outcome measurement is essential to ensure a multidimensional and comprehensive approach to device prescription for individuals with HP.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
