Music-supported vocal rehabilitation-operationalized through the Accent Method (AM), a rhythm- and breathing-based voice therapy approach grounded in hierarchical respiratory-phonatory-prosodic coordination-offers a theoretically grounded mechanism for addressing PD dysarthria by exploiting the well-documented facilitatory effect of external rhythmic auditory cueing on motor control in PD. Despite widespread clinical use of the AM in Scandinavian centers, rigorous controlled evidence for its effects on voice intensity and speech performance in PD remains limited. Prospective, parallel-group, randomized controlled trial comparing a structured, four-phase PD-adapted AM protocol with an active nonspecific control program (vocal hygiene and general breathing exercises) over 20 weeks. Ninety-two adults with idiopathic PD (Hoehn and Yahr stages 2-3) were randomized to music-supported AM rehabilitation (n = 46) or active control (n = 46). Blinded assessors evaluated outcomes at baseline and at 6, 12, and 20 weeks. Primary outcome: Voice Handicap Index-30 (VHI-30). Secondary outcomes: GRBAS perceptual dysphonia scale, sound pressure level (SPL), maximum phonation time (MPT), acoustic parameters (jitter, shimmer, fundamental frequency [F0]), speech intelligibility rated by blinded naive listeners, UPDRS speech sub-item, and PDQ-39 communication subscale. All between-group comparisons at 20 weeks favored music-supported AM rehabilitation (all P < 0.001, Bonferroni corrected; adjusted α = 0.005). VHI-30 improvement: -36.8 points (AM) vs. -9.4 points (Control); between-group difference 26.8 points (95% CI: 22.2-31.4; Cohen's d = 2.47). Voice intensity (SPL) improved by +14.8 dB in the AM group versus +4.3 dB in the control group-a nearly threefold greater improvement. Speech intelligibility improved from 67.4% to 84.6% in the AM group versus 68.1% to 73.4% in the control group (+17.2%-point between-group difference), representing a movement from clinically impaired intelligibility to near-functional communicative levels. Jitter normalized from 4.12 ± 0.98% to 1.04 ± 0.31% (AM) versus 4.08 ± 0.94% to 2.96 ± 0.77% (Control), and shimmer from 10.41 ± 2.37% to 3.18 ± 0.84% versus 10.28 ± 2.29% to 6.74 ± 1.61%.

Current methods of diagnosis may be based on subjective clinical examination and disjointed rehabilitation regimens, which may lack accuracy and scalability. The study introduces the VocaSense-X Framework, a comprehensive intelligent system for improving voice medicine through integrated diagnosis and rehabilitation. The framework uses multimodal signal processing, deep learning models, and adaptive feedback mechanisms to provide accurate, data-driven analysis of vocal pathologies, including dysphonia, vocal fold lesions, and neurogenic voice disorders. VocaSense-X is a model that combines a real-time acoustic feature extraction pipeline with a hybrid convolutional-recurrent neural network, achieving superior classification performance across a wide range of patient populations. The framework includes a personalized rehabilitation module that dynamically adjusts therapeutic exercises based on continuous monitoring of the voice, enabling tracking of the patient's progress over time and supporting diagnosis. The experimental analysis using benchmark voice disorder datasets demonstrates that the diagnostic performance of VocaSense-X is significantly better than that of any other comparator architecture tested under the same experimental setup, with an accuracy of > 94. Furthermore, clinician usability tests confirm the framework's usability in both clinical and teletherapy settings. The system proposed herein is designed to fill the gap between intelligent computation and clinical voice medicine, is scalable and evidence-based, and can be used for early detection and structured voice rehabilitation. The implications of VocaSense-X for otolaryngology, speech-language pathology, and digital health platforms make it a pivotal step towards AI-driven voice healthcare innovations.</p>","PeriodicalId":49954,"journal":{"name":"Journal of Voice","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148992185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to systematically review AI voice and speech models for detecting AD and MCI, and to evaluate their translational potential.</p><p><strong>Methods: </strong>Following PRISMA guidelines, two investigators searched PubMed, Scopus, and the Cochrane Library for studies reporting diagnostic and prognostic outcomes of AI voice and speech models in AD and MCI. Data were extracted from studies applying machine learning (ML) or deep learning (DL) to human speech with quantitatively reported, clinically interpretable outcomes. Methodological quality and risk of bias were formally appraised using the PROBAST and CLAIM tools.</p><p><strong>Results: </strong>Sixty-three studies were included. Of the 18,540 participants, there were 8,044 patients (mean age: 73.1 years), 9,736 controls (mean age: 67 years), and 760 with unspecified dementia diagnoses. There were 9,571 females and 8,341 males (628 unspecified). Most reported high diagnostic performance for distinguishing AD from healthy controls using prosody (n = 41), temporal (n = 38), spectral (n = 35), and linguistic (n = 21) measures, frequently achieving areas under the curve greater than 0.80. In contrast, MCI was less reliably distinguished from normal aging. AI-based speech analysis thus represents a promising and scalable digital biomarker, but the current evidence base remains heavily constrained by small, single-center datasets and a widespread lack of external validation.</p><p><strong>Conclusion: </strong>AI-driven speech analysis holds significant potential for the early detection of cognitive decline. However, its clinical translation is currently limited by methodological bias. Future validation efforts must shift toward large-scale, multicenter, longitudinal studies with standardized speech assessments.</p>","PeriodicalId":49954,"journal":{"name":"Journal of Voice","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148957204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
