• SLPOther2024Infraglottal Medialization: Increasing Vocal Fold Stiffness Gradient for Improved Vocal Efficiency.Journal of voice : official journal of the Voice FoundationIn excised dog larynges, placing the medialization implant below the vocal fold edge increased vocal efficiency by 31%, compared to 29% when placed at the fold level. This suggests inferior placement restores a stiffness gradient that may improve voice mechanics.
• SLPSystematic Review2025Upper Airway Sensory Testing in Dysphagia - Implications for Clinical Practice and Future Research Directions.DysphagiaThe review found no standard way to test upper airway sensation in swallowing. FEESST and cough reflex tests were most common, but stimuli and normal criteria varied widely. Gag reflex testing is unreliable because many healthy people lack it. Taste testing is cheap but also lacks standard methods.
• SLPOther2024Prosodic Preferences of Surface Electromyography-based Subvocal Speech for People With Laryngectomy.Journal of voice : official journal of the Voice FoundationPeople with laryngectomy and their communication partners rated synthetic speech with continuous pitch mapping as more natural than electrolarynx speech. They prioritized sound quality and intelligibility over ease of use, suggesting future devices should focus on voice naturalness rather than just usability.
• SLPOther2024Patient-Perceived Vocal Effort Immediately Following Voice Tasks in Adductor Laryngeal Dystonia (ADLD).Journal of voice : official journal of the Voice FoundationWhen patients with adductor laryngeal dystonia rated vocal effort immediately after a reading task, scores on a visual analog scale and the OMNI-VES were strongly related. However, these effort ratings showed only weak links to voice-related quality of life scores. Clinicians need to track both.
• SLPQualitative2025Speech and language therapist-led clinics for low-risk suspected head and neck cancer referrals: A qualitative study of ear, nose and throat surgeons' views.International journal of language & communication disordersENT surgeons supported the idea of speech therapists assessing low-risk cancer referrals but disagreed on how to do it safely. They highlighted that therapists need dedicated time, specific endoscopy training, and clear governance rules, rather than just adding this to their existing workload.
• SLPCohort2024Characterizing Vocal Hyperfunction Using Ecological Momentary Assessment of Relative Fundamental Frequency.Journal of voice : official journal of the Voice FoundationNeck-sensor voice monitoring distinguished patients with phonotraumatic vocal hyperfunction from healthy controls in daily life, with better accuracy than in the lab. It did not separate those with muscle tension dysphonia. The sensor also failed to track patients' self-reported vocal effort in real-world settings.
• SLPCase-Control2025Vocal and Facial Behavior During Affect Production in Autism Spectrum Disorder.Journal of speech, language, and hearing research : JSLHRChildren with autism showed reduced facial expressivity, particularly smaller eye opening and lip width during happy and afraid speech, compared to controls. Human raters were less accurate in identifying emotions from these children's faces, though vocal accuracy did not differ significantly overall.
• SLPOther2025Vocal Instabilities in Untrained Female Singers.Journal of voice : official journal of the Voice FoundationUntrained singers can produce smooth scales, but objective signals reveal hidden instabilities like pitch overshoots and airflow changes that the ear misses. Voice breaks and sudden intensity drops were the only signs always heard, marking the most unsteady performances.
• SLPCase-Control2025Salient Voice Symptoms in Primary Muscle Tension Dysphonia.Journal of voice : official journal of the Voice FoundationPatients with muscle tension dysphonia reported significantly higher vocal effort, fatigue, and discomfort than healthy controls. Acoustic voice quality and pain did not differ between groups. Standard self-report questionnaires accurately captured these symptoms at the time of evaluation.
• SLPOther2025Impact of High- and Low-Pass Acoustic Filtering on Audiovisual Speech Redundancy and Benefit in Children.Ear and hearingFor children with typical hearing, seeing the talker helped word recognition more when only low-frequency speech was audible than when only high-frequency speech was audible. For sentences, seeing the talker helped similarly in both filtered conditions.
• SLPQualitative2025Do you like my voice? Stakeholder perspectives about the acceptability of synthetic child voices in three South African languages.International journal of language & communication disordersStakeholders in South Africa accepted synthetic child voices in English, Afrikaans, and isiXhosa, though they rated the English child voice as less natural and harder to understand. They emphasized that children should choose their own voice to match their identity, and that partner support is critical for adoption.
• SLPOther2025Aerodynamic and Acoustic Power in Infant Cry.Journal of voice : official journal of the Voice FoundationNo clinical finding to act on. This paper models infant cry using assumed anatomy and pressures, not measured patients.
• SLPCohort2025Rethinking speech sound disorder (SSD) in non-syndromic cleft lip and palate: The importance of recognizing phonological and language difficulties.International journal of language & communication disordersChildren with cleft palate and phonological speech errors had significantly lower language scores than those with typical speech or cleft-specific articulation errors. The combined phonological and cleft group was over ten times more likely to have expressive language difficulties, warranting full language assessment.
• SLPOther2025Clinical Swallow Examination Following Laryngectomy: An International e-Delphi Consensus Process.DysphagiaInternational speech pathologists agreed on 34 items for examining swallowing after laryngectomy. The framework drops standard checks like voice quality and aspiration, focusing instead on effort, backflow, and the patient's history to match this population's unique anatomy.
• SLPOther2025Effects of Increasing Vocal Tract Insertion Depth in Semi-Occluded Vocal Tract Exercises on an Excised Canine Model.Journal of voice : official journal of the Voice FoundationInserting a straw into the mouth reduces the pressure needed to start phonation. However, pushing the straw deeper into the vocal tract does not provide any additional benefit compared to a standard shallow insertion.
• SLPCohort2025Different measures of fundamental frequency and vocal satisfaction among transgender men and women.CoDASFor transgender men, no acoustic measure correlated with voice satisfaction. For transgender women, only higher maximum pitch during counting linked to better satisfaction. Mean pitch alone did not predict how satisfied either group was with their voice.
• SLPSystematic Review2025Quality assessment of clinical guidelines in the care of laryngitis and pharyngitis according to AGREE II.CoDASMost guidelines for sore throat and hoarseness rely on drugs, with less than half recommending voice rest or hydration. While methodological quality was high, non-pharmacological care is inconsistently addressed across the seven guidelines assessed.
• SLPOther2025Script Voz - clinical case simulator of adults with behavioral dysphonia: planning and content creation.CoDASA new web simulator called Script Voz is being built to help speech therapists practice clinical reasoning for behavioral dysphonia. It guides users through assessment, diagnosis, and treatment planning using real cases and expert consensus. The tool is not yet released for public use.
• SLPCase-Control2025Voice handicap, vocal fatigue, and voice-related quality of life in patients with multiple sclerosis.CoDASPeople with multiple sclerosis reported significantly higher voice handicap and vocal fatigue, and lower voice-related quality of life, than matched controls. The link between these symptoms was stronger in the MS group. Standard questionnaires identified these issues even when patients did not complain of voice problems.
• SLPOther2025Analysis of the immediate effect of the high-frequency oral oscillation exercise on individuals with and without vocal symptoms.CoDASBlinded judges mostly did not hear a difference after three minutes of the Classic Shaker voice exercise, although all four groups reported less vocal discomfort and some voice sound measurements changed.
• SLPOther2025Self-perception of vocal fatigue and insomnia severity in teachers.CoDASTeachers with voice problems reported significantly worse vocal fatigue and insomnia than those without, though both groups had frequent fatigue symptoms. Women made up 58.3% of the at-risk group compared to 37.5% of men. Poor working conditions like noise and stress were common in both groups.
• SLPCohort2025The robustness of speech-like vocalization in typically developing infants and infants with autism.Research in developmental disabilitiesInfants with autism or developmental disabilities produced speech-like sounds at the same high rates as typically developing infants during the first year. Volubility did not predict later language or cognitive outcomes, so low sound production is not a reliable early marker for these groups.
• SLPOther2025Photobiomodulation on vocal training and rehabilitation: Delphi consensus based on experts.CoDASSeven voice specialists agreed on how they use photobiomodulation as an add-on to vocal training, including for voice professionals without dysphonia and behavioral dysphonia without laryngeal injury. This is expert practice agreement, not proof that photobiomodulation works.
• SLPOther2025Use of a self-perception questionnaire for screening auditory abilities in children with behavioral dysphonia.CoDASParents reported significantly more auditory difficulties in children with behavioral dysphonia than the children did themselves. High voice symptom scores correlated with high risk for central auditory processing disorder, suggesting parents' reports are a useful screening signal in voice clinics.
• SLPOther2025Effects of the Program for Developing Oral Communication Expressiveness on university radio announcers: a pre/post intervention study.CoDASEight university radio announcers reported better diction and voice sound after an eight-session communication program. Judges rated half the post-training readings as superior, and acoustic analysis showed increased clarity. No control group was used, so these changes cannot be attributed solely to the training.
• SLPOther2025Performance of swallowing function between older people with and without clinical complaints.CoDASOlder adults with swallowing complaints had more tongue weakness, hoarse voice, throat residue with liquids, and lower oral intake than those without complaints. Lower intake went with more residue and nutritional risk.
• SLPPilot2025Treatment Effects of Combined Transoral Injection Laryngoplasty with Short Voice Therapy in Patients with Unilateral Vocal Fold Immobility: A Pilot Study.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)Seventeen patients treated with office-based vocal fold injection and short voice therapy showed significant improvements in hoarseness, loudness, and voice handicap. Because both treatments were given together, the contribution of any single component cannot be separated.
• SLPPilot2025Comparing the Effects of Sensory Tricks on Voice Symptoms in Patients With Laryngeal Dystonia and Essential Vocal Tremor.Journal of speech, language, and hearing research : JSLHRSensory tricks like vibrotactile stimulation and delayed auditory feedback did not improve voice symptoms in laryngeal dystonia. Instead, listeners rated the voice quality as worse under these conditions. This contradicts the hypothesis that sensory tricks act as a beneficial diagnostic marker.
• SLPCohort2025Estimating Pressed and Breathy Phonation From Cepstral and Spectral Measures.Journal of voice : official journal of the Voice FoundationIn healthy voices, pressed phonation raises CPP and lowers H1-H2, while breathy phonation does the opposite. Higher CPP is not always better: it can signal hazardous pressed voice. H1-H2 discriminated pressed from typical voice across tasks, especially in women, though men showed less consistent vowel results.
• SLPOther2025Open-Source Manually Annotated Vocal Tract Database for Automatic Segmentation from 3D MRI Using Deep Learning: Benchmarking 2D and 3D Convolutional and Transformer Networks.Journal of voice : official journal of the Voice FoundationAn open-source database of 53 manually annotated vocal tract MRI volumes from 10 French speakers provides a benchmark for automatic segmentation. The best 3D U-Net models reached 0.896 on a 0-to-1 overlap scale, and transfer learning reached that with 20 volumes instead of 45.
• SLPOther2025Impact of imitation abilities on social communication in autistic children: evidence from an Early Start Denver Model intervention study.Molecular autismImprovements in imitation skills strongly predicted gains in social communication. ESDM improved imitation more than conventional therapy but showed no significant advantage for social communication overall. Older children benefited more from imitation gains than younger ones.
• SLPPilot2025Early Insights Into the Role of Personality in Adherence to Voice Rest After Phonomicrosurgery.Journal of voice : official journal of the Voice FoundationPatients who scored higher on Extraversion used their voices less during post-surgery voice rest, meaning they were more adherent. This contradicts the expectation that talkative people struggle to stay silent. Men showed a stronger link between Extraversion and voice use than women.
• SLPPilot2025Babble Boot Camp for Infants With Down Syndrome: Piloting a Proactive, Caregiver-Led Intervention Designed to Boost Earliest Speech and Language Skills.American journal of speech-language pathologyTen infants with Down syndrome received caregiver-led telehealth Babble Boot Camp, and average family session attendance was 92%. Some showed babble growth and first words emerged, but without a Down syndrome control group the pilot cannot show the intervention caused it.
• SLPCase Report2025Clinical Case Study: Pediatric Exercise-Induced Laryngeal Obstruction.Perspectives of the ASHA special interest groupsA 13-year-old runner diagnosed with exercise-induced laryngeal obstruction improved after three speech therapy sessions including education, trigger management, lower thoracic breathing, rescue breathing, and real-world practice. She resumed track, but this single case cannot show which component helped.
• SLPOther2025Uncertainty of Spatial Segmentation of High-Speed Videoendoscopy and Its Temporal and Spatial Dependency.Journal of voice : official journal of the Voice FoundationManual segmentation of vocal fold edges in high-speed video is less accurate at the front and back of the glottis and when the glottis is wide open. This means measures like velocity in these areas have higher uncertainty.
• SLPPilot2025Voiced-Voiceless Consonant Distinction in Children With Vocal Fold Nodules: A Preliminary Study.Journal of voice : official journal of the Voice FoundationMost consonant timing measures did not track voice disorder in children with vocal fold nodules. Voiced-voiceless distinction did track voice disorder in the 5 to 6 and 6 to 7 groups.
• SLPCase-Control2025Tongue pressure and self-assessment of swallowing after total laryngectomy.CoDASLaryngectomy patients had higher tongue dorsum pressure than controls, but no difference in tongue tip pressure. Tongue pressure did not correlate with self-reported swallowing symptoms. Patients most commonly reported needing liquids to help food go down and difficulty with dry foods.
• SLPCohort2025Characterization of swallowing in older adults with dementia.CoDASSwallowing signs were more frequent at higher dementia stages: mild dementia had more solid residue than neurotypical adults, and severe dementia had liquid spillage, oral residue, longer liquid transit, cough with solids, abnormal neck sounds, and oxygen saturation drops with liquid.
• SLPNarrative Review2025The Pediatric Vocal Mechanism: Structure and Function.Journal of voice : official journal of the Voice FoundationChildren's vocal folds are structurally and functionally different from adults, with shorter length, undifferentiated tissue, and higher subglottal pressure. Voice measures change predictably with age and sex, so clinical assessment must use pediatric-specific norms rather than adult standards.
• SLPOther2025Acoustic and Psychoacoustic Analyses of Predominant Strain Elicited via Modulated Vocal Effort.Journal of voice : official journal of the Voice FoundationWhen people with normal voices produced strain by imagining lifting heavy boxes, a computer measure called 'sharpness' tracked the strain better than any other acoustic metric. It successfully separated mild strain from severe strain, whereas common measures like jitter and cepstral peaks failed to distinguish the levels.
• SLPRCT2025Efficacy of a Tesla Valve Straw in a Semi-Occluded Vocal Tract Exercise in a Normal-Voiced Population.Journal of voice : official journal of the Voice FoundationStraw phonation reduced phonation threshold pressure in healthy adults, making voice production easier. However, a novel Tesla valve straw was no more effective than a standard straw. The benefit came from the semi-occlusion itself, not the specific straw design or length.
• SLPCohort2025Relationships Between Aerodynamics and Voice Symptoms in Primary Muscle Tension Dysphonia.Journal of voice : official journal of the Voice FoundationPatients with muscle tension dysphonia reported significantly higher vocal effort, fatigue, and discomfort than controls, but their aerodynamic measures showed no significant differences. Self-perceived symptoms did not correlate with airflow or pressure data, suggesting these are separate aspects of the disorder.
• SLPCohort2025Rapid Increases in Children's Spontaneous and Responsive Speech Vocalizations Following Cochlear Implantation: Implications for Spoken Language Development.Ear and hearingChildren with cochlear implants made rapid jumps in speech and caregiver interaction after activation. More back-and-forth talking predicted better auditory comprehension. This supports prioritizing early device use and coaching families on responsive vocal turn-taking.
• SLPPilot2025Disease Control and Voice Outcomes Following Treatment With PRGN-2012 in Adults With Recurrent Respiratory Papillomatosis.Journal of voice : official journal of the Voice FoundationIn adults with recurrent respiratory papillomatosis, patients who responded well to PRGN-2012 gene therapy saw significant drops in both visible papilloma disease and self-reported voice handicap. Fewer lifetime surgeries before treatment correlated with better voice outcomes, though the study was small.
• SLPOther2025Effects of Sustained Semi-Occluded Vocal Tract Exercises in Non-Disordered Populations.Journal of voice : official journal of the Voice FoundationIn healthy adults, straw phonation lowered the pressure needed to start voicing, regardless of straw length. The benefit did not last one week after stopping, and other airflow measures did not change.
• SLPPilot2025Preliminary Investigation of Four Voice Therapy Concepts in a Single-Subject Design with Four Professional Teachers.Journal of voice : official journal of the Voice FoundationIn four teachers, both voice therapy models raised recorded pitch and lowered self-rated roughness and strain, but neither clearly beat the other. The full model trained voices for quiet, loud, and noisy teaching; the reduced model trained one voice.
• SLPOther2025Reliability and Diagnostic Accuracy of Semi-Automated and Automated Acoustic Quantification of Vocal Tremor Characteristics.Journal of speech, language, and hearing research : JSLHRSemi-automated acoustic analysis matched manual vocal tremor measurements closely, with correlations above .9 across all properties. Fully automated analysis varied widely, reaching only .5 for pitch rate. Diagnostic accuracy was acceptable for both automated and semi-automated extent measures, but thresholds require confirmation in larger samples.
• SLPCohort2025Comparison of Voice Stimulability Testing in Telehealth and In-Person Formats.Journal of voice : official journal of the Voice FoundationTelehealth and in-person voice evaluations showed no significant difference in overall stimulability ratings. Age, not modality, was significant: younger patients rated higher stimulability than older patients. Semi-occluded tasks trended lower on telehealth but did not reach significance.
• SLPQualitative2025Exploring the Perceptions of Voice-Assisted Technology as a Tool for Speech and Voice Difficulties: Focus Group Study Among People With Parkinson Disease and Their Carers.JMIR rehabilitation and assistive technologiesPeople with Parkinson disease described using smart speakers as prompting them to speak louder and clearer to be understood. While this mimics speech therapy goals, participants reported frustration with device errors and distrust of privacy, suggesting technology alone is not a substitute for human therapy.
• SLPOther2025Automated Analysis of Relative Fundamental Frequency in Continuous Speech: Development and Comparison of Three Processing Pipelines.Journal of voice : official journal of the Voice FoundationThree automated pipelines for measuring vocal effort in continuous speech matched manual analysis. The aRFF-B pipeline rejected the fewest samples and is recommended for large-scale use, though vocal fry in female voices remains a major cause of data loss.
