• PTOTSLPSystematic Review2026A Scoping Review to Map Health Outcomes in Inducible Laryngeal Obstruction.International journal of language & communication disordersAcross 49 studies on inducible laryngeal obstruction, outcome measures varied widely with no standard set. Patient-reported questionnaires dominated, but few captured environmental or personal factors. Current tools miss key life impacts, so results cannot be reliably compared across studies.
• SLPQualitative2025Developing a FEES service in South Africa: Interdisciplinary reflections for dysphagia care.The South African journal of communication disorders = Die Suid-Afrikaanse tydskrif vir KommunikasieafwykingsFour dysphagia clinicians reflected that building a bedside FEES service depended on ENT, SLT and nursing collaboration, protected scheduling, shared endoscope access, and education to overcome scepticism. They described FEES helping guide diet and feeding decisions, but gave no patient outcomes.
• SLPOther2026Listening in a noisy world: The impact of acoustic cues and background music on speech perception in autism.Autism : the international journal of research and practiceAutistic adults understood speech in noise less accurately overall. With both voice and location cues, their accuracy matched non-autistic adults. Background music lowered accuracy overall, with the clearest drop in non-autistic adults when both cues were present.
• SLPOther2026Immediate Effects and 1-Year Maintenance of a Voice Education Program for Older Adults.International journal of language & communication disordersA four-session voice education program improved older adults' knowledge of vocal hygiene, with gains maintained one year later. Participants reported applying practices like drinking more water and reducing voice volume, though memory issues and habit-breaking remained barriers for some.
• SLPOther2026Construct Validity of the Brazilian Portuguese Version of the Thyroidectomy-Related Voice and Symptom Questionnaire (BR-PT-TVSQ).International journal of language & communication disordersThe Brazilian Portuguese thyroidectomy symptom questionnaire grouped patient-reported problems into voice, throat and neck/chest domains. Voice symptoms formed the largest group, but throat and neck/chest items overlapped.
• SLPOther2026Clinician Perceptions of Phonatory-Respiratory Kinematic Patterns in Primary Muscle Tension Dysphonia.Journal of voice : official journal of the Voice FoundationExpert clinicians watching videos of people with muscle tension dysphonia identified respiratory patterns like neck tension and shallow breathing, but could not reliably diagnose the condition. Visual cues alone are insufficient for diagnosis and require objective measurement.
• SLPOther2026Perceiving Physiology from the Voice: Evidence for Physiological Coupling Between Laryngeal and Epilaryngeal Adjustments.Journal of voice : official journal of the Voice FoundationHighly trained listeners identified intended laryngeal configurations from voice with moderate agreement and 68% accuracy. They struggled to distinguish subtle false vocal fold positions and perceived conflicting anatomical combinations as ambiguous or incorrect.
• SLPCase-Control2026Neurobehavioral Assessment of Sensorimotor Function in Autism Using Smartphone Technology.Autism research : official journal of the International Society for Autism ResearchSmartphone-based tests showed children with autism had reduced sensorimotor gating and higher startle variability than neurotypical peers. Behavioral differences like screen avoidance and vocalizations were also prominent, suggesting digital tools can objectively measure sensory processing differences.
• SLPOther2026Children's Ability to Identify and Describe Dysphonia: A Multimethod Study.International journal of language & communication disordersChildren correctly identified dysphonia in other children's voices 70% of the time, but accuracy varied widely. When asked to describe voices, many confused voice quality with speech content or articulation. Clinicians should not assume children understand the difference between voice and speech disorders.
• SLPCohort2026Clinical predictors of dysphagia in patients with sepsis in a high-complexity hospital: insights for early identification.CoDASIn 35 sepsis patients, those with swallowing problems were more likely to have had prior neurological disease, require tube feeding, and die. Pre-existing neurological conditions and lung infections flagged high risk for dysphagia, warranting early speech therapy screening.
• PTOTSLPOther2026Accuracy of Balloons and Handheld Spirometers as Low-Cost Tools for Measuring Vital Capacity and Air Volume: A Laboratory-Based Validation Study.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)In a lab setting, a $150 digital spirometer and a $1 balloon measured injected air volumes with small, predictable errors compared to expensive clinical equipment. These low-cost tools accurately estimate vital capacity when simple mathematical corrections are applied.
• SLPCohort2026Quantitative temporal analysis of posterior oral spillage in a dual-task for individuals with Parkinson's disease.CoDASSwallowing while performing a motor task slowed oral control in people with Parkinson's, but only for thick liquids at small volumes reached statistical significance. This suggests distraction impacts specific swallowing mechanics, not necessarily overall safety, in this small group.
• SLPOther2026Influence of Bolus Location and Age on Timing Measures of Swallowing in Healthy Older Adults.Perspectives of the ASHA special interest groupsIn healthy older adults, bolus location varied across swallows. When the bolus was lower at swallow onset, reaction time was longer. Age was linked to slower onset and shorter swallowing intervals on some trials. Do not rely on one swallow.
• SLPCohort2026Parental Stress and Caregiver Role Modulate Child-Caregiver Prosodic Synchrony in Autism: A Computational Analysis.Autism research : official journal of the International Society for Autism ResearchAmong 26 autistic preschoolers, higher parent stress and father-child interactions were linked to less steady, more fluctuating vocal coordination during play. This was an association, not evidence that changing either improves outcomes.
• SLPOther2026Dyadic synchrony in deaf mothers and hearing infants.Journal of deaf studies and deaf educationMost deaf mothers and hearing infants showed adequate or better play; 21% had less warm, less engaged play that may need support. Lower household income was linked to poorer interaction.
• SLPCase Report2026Voice Therapy for Puberphonia in the Adolescent Male: A Clinical Case Study.Perspectives of the ASHA special interest groupsManual laryngeal reposturing rapidly normalized pitch in an adolescent with puberphonia, but only after semi-occluded exercises reduced muscle tension enough for him to tolerate the maneuver. Counseling the family on the social impact of a sudden voice change was essential for successful generalization.
• OTSLPOther2026Flow Characteristics of Barium Thickened Liquids during Swallowing in Healthy Adults.DysphagiaIn healthy adults, thicker barium liquids kept the bolus in the mouth at first swallow, while thin liquids often reached the throat. Gum-based thickeners did not consistently change transit times compared with starch-based.
• PTOTSLPOther2026Hands-free control of an assistive robotic arm for high-level paralysis.Journal of neuroengineering and rehabilitationHead, tongue, and facial muscle controls let people reach targets with a robotic arm as fast as a hand-operated joystick. Voice control was slower. These hands-free options may offer people with high-level paralysis a safer, cheaper alternative to brain implants.
• SLPCase-Control2026Communicative Adaptations After Laryngectomy: Syntactic Complexity and Gesture Use.International journal of language & communication disordersLaryngectomy patients use comparable syntax and gestures to healthy controls but pause more and speak fewer words. They rely on silent pauses to breathe and plan rather than verbal fillers, which may make it harder to hold the floor in conversation.
• SLPPilot2026Delivering a Voice Education Program to School-Age Children through the Lens of Science, Technology, Engineering, and Mathematics.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)A STEM-based voice education program significantly increased students' voice care knowledge immediately after training. One year later, scores remained similar to post-training levels, though individual item retention varied. The study was a small pilot without a control group.
• SLPOther2026Performance of Nonlinear Energy Difference Ratio and Voice Type Component Profile Across Phoneme, Relative Sound Pressure Level, and Environment.Journal of voice : official journal of the Voice FoundationNEDR stayed mostly stable for vowels and voiced fricatives, but changed with /s/, very soft speech, and noise. VTCP moved more with loudness, sound type, and recording environment. Use the same sound and quiet room when interpreting them.
• SLPMeta-Analysis2026Effects of Transcranial Direct Current Stimulation on Speech and Voice Changes in Parkinson's Disease: a Systematic Review with Meta-Analysis.CoDASCombining six small studies, tDCS did not significantly improve speech or voice in Parkinson's. The overall result was null, with high variability between studies. Do not assume tDCS works for these symptoms based on this evidence.
• SLPOther2026Effects of inspiratory muscle training for 28 days on the voice of women without vocal complaints.CoDASNo perceptual voice change was seen, but acoustic stability and noise measures improved, along with maximum phonation times, diadochokinesis, and self-rated voice quality of life, handicap, and symptoms after 28 days of Respiron training in 22 vocally healthy women.
• SLPCohort2026The effects of smoking on the dynamic vocal range of male smokers.CoDASMale smokers had a smaller vocal range than non-smokers, hitting lower top notes and unable to whisper as quietly. Longer smoking history and higher daily cigarette counts were linked to these reductions. This suggests smoking physically limits vocal flexibility.
• SLPRCT2026Implicit and Explicit Voice Training Effects on Speech-on-Speech Perception and Listening Effort.Ear and hearingNeither voice training method improved speech intelligibility. However, both methods reduced listening effort in specific difficult conditions. Explicit training generally required less cognitive load than implicit training. These benefits appeared only when background noise levels were unfavorable, with no overall performance gain.
• SLPCase-Control2026Automated Creak Detection in Spanish Speakers with and without AdLD.Journal of voice : official journal of the Voice FoundationAutomated creak percentage was higher in Spanish-speaking individuals with adductor-subtype laryngeal dystonia than controls and glottic insufficiency. It was better at identifying people without dystonia than at finding people with dystonia.
• SLPSystematic Review2026Outcomes of Voice Therapy in Behavioral Voice Disorders: A Scoping Review-Part A.Journal of voice : official journal of the Voice FoundationAcross 438 studies of voice therapy for adults with behavioral voice disorders, the measures used most were vocal complaint, laryngeal imaging, self-assessment, acoustic analysis and auditory-perceptual judgment. Aerodynamic testing appeared in only 174 of them, and the authors say the field's assessment habits have barely changed in twenty years.
• SLPCohort2026Individual, occupational, and dysphonia-related factors in operational and administrative military police officers.CoDASOperational and administrative military police reported hoarseness, vocal effort and voice-related absence at similar rates, and about 9% of all officers screened as likely to have dysphonia. Operational work meant more noise, more threats and less support at work.
• SLPOther2026Visual Gestures of the Head and Eyebrows Support Prosody Perception for Individuals with Cochlear Implants.Trends in hearingHead nods and eyebrow raises on one word made listeners echo that word in a higher pitch even when the voice carried no emphasis. Cochlear implant users leaned on those gestures more: 37% versus 15% of a real pitch peak's effect.
• SLPCase-Control2026Screening and analysis of the risk of dysphonia based on general and specific screening protocols in teachers with and without voice disorders.CoDASTeachers with and without voice disorders scored almost the same on both dysphonia risk screening questionnaires, and both groups scored above the high-risk cutoff. Their risk scores did not match how severe their voices sounded. Only hydration and smoking separated the groups, slightly.
• SLPOther2026Effect of speech recognition test presentation on cochlear implant user performance.CoDASCochlear implant users scored higher on speech tests when the tester spoke the sentences aloud than when they heard a recording: live voice beat recorded by 15.58 points for words and 19.07 for sentences in quiet. In noise the two came out level.
• SLPCase Report2026Case Report: Tailored automatic speech recognition in global aphasia with dysarthria - a single case proof of concept.Frontiers in rehabilitation sciencesA system trained on one woman's voice recognised her intended word in 72.65% of 936 attempts, against 56.75% for twelve rehabilitation professionals who knew her speech. One patient and a 13-word vocabulary, so not proof it generalises.
• SLPSurvey2026Association between the feeling of vocal comfort and social security when wearing a protective mask: a study with transgender people.CoDASThree quarters of 85 transgender adults said wearing a face mask made them feel socially safer, while just over half found masks uncomfortable. Comfort with the mask was the only thing that predicted feeling safer.
• SLPOther2026Content-based validity evidence of the Acute Voice Fatigue Self-Perception Scale (AFA-Voz Scale).CoDASA new scale asks voice users to rate right now their fatigue, neck or throat discomfort, and limitation in voice use, each from 0 to 10. Five voice experts judged every item fully relevant. It has not been tested with patients, so it is not ready for clinical use.
• SLPOther2026Glottal Area Waveform Measurements for Healthy Female and Male Speakers in Typical, High-Frequency, and Soft Phonation.Journal of speech, language, and hearing research : JSLHRTo raise pitch, healthy adults mainly stretched the vocal folds with the cricothyroid muscle. Soft voice needed that plus less firm closure of the folds. Men and women started from different baselines, so normal values differ by sex.
• SLPCohort2026Turn-Taking and Vocal Coordination in Mother-Child Mixed-Hearing Dyads and the Effect of Home Music Engagement: A Longitudinal Study on Italian Children With Cochlear Implants.International journal of language & communication disordersMothers of children with cochlear implants responded to them less often than mothers of hearing children, and the implanted children overlapped their mothers' speech more, before and a year after implantation. In that group, more music at home went with shorter, steadier pauses between turns.
• SLPCohort2026Development and validation of the Brazilian voice bank for various emotions (EMOVOX-BR).CoDASTen experienced voice therapists correctly identified the intended emotion in more than 70% of the clips in a new Brazilian Portuguese audio bank of 39 recordings. They relied on pitch for every emotion, and on loudness only for anger.
• SLPCohort2026Hearing assessment of infants with congenital syphilis.CoDASNo hearing loss was found in infants treated for congenital syphilis. Sixty-one of 65 passed newborn screening and none of the 23 seen at 3 months had abnormal brainstem responses. Most did not return for that check.
• SLPOther2026Interrater reliability in the application of the VPAS-PB: analysis among experienced judges.CoDASThree experienced raters scored voice qualities consistently across most VPAS-PB adjustments in 10 vocally healthy men, but lip stretching and falsetto did not reach the same standard. Disordered voices and less experienced raters were not tested.
• SLPCohort2026Combined effect of self-perceived voice disorders and hearing loss on social acts in older adults: a 1-year longitudinal study.Journal of physical therapy scienceOlder adults who reported voice problems went out less over a year, from 4.1 to 3.2 days a week. Those with hearing problems alone showed no significant change. People with both declined too, but that combined result was only marginally significant.
• SLPPilot2026Respiratory-Swallow Training and Variable Practice in Parkinson's Disease: A Clinical Trial Pilot Study.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)Four weekly sessions teaching people with Parkinson's to breathe out before and after swallowing raised the proportion of swallows with that pattern from 38.4% to 71.7%, with less residue and less material entering the airway. There was no untreated control group.
• SLPOther2026Forming a choir with total laryngectomized patients.CoDASNot a study: this describes how one university clinic formed a choir with total laryngectomy patients, with no outcome measures and no comparison group, so it does not show the choir works.
• SLPSystematic Review2026Indicators for evaluating public speaking in adults: a scoping review.CoDASThe rating scales used to judge adult public speaking are mostly homemade: 26 of 35 studies used indicators the researchers wrote themselves rather than a validated tool. Four areas recur anyway: how the talk is structured, nonverbal behaviour, voice, and language.
• PTSLPSystematic Review2022Non-pharmacological Management of Non-productive Chronic Cough in Adults: A Systematic Review.Frontiers in rehabilitation sciencesSome non-drug treatments improved cough-related quality of life for long-standing dry cough, including speech and language therapy, physiotherapy and CPAP for sleep apnoea. But cough severity, anxiety and depression did not change, and a three-month follow-up of the physiotherapy and speech-language programme found no difference.
• SLPRCT2025The Language ENvironment Analysis (LENA) System in Toddlers With Early Indicators of Autism: Test-Retest Reliability and Convergent Validity With Clinical Language Assessments.Autism research : official journal of the International Society for Autism ResearchConversational turn counts from an in-home wearable recorder lined up with autistic toddlers' language scores, even after accounting for how much the child vocalized. Plain adult-word and child-vocalization counts did not. Repeat recordings of the same child agreed moderately well.
• SLPRCT2025Pharyngeal Residues Scoring through the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS): Efficacy of Training.DysphagiaA 160-minute online course did not bring clinicians' pharyngeal residue scores on FEES videos any closer to expert ratings than untrained colleagues, and agreement between raters did not change. Only pyriform sinus video scores improved within the trained group.
• SLPRCT2025The PD COMM Process Evaluation: Describing Interventions and Implementation in a UK Pragmatic Randomised Controlled Trial of Speech and Language Therapy for People With Parkinson's-Related Dysarthria.International journal of language & communication disordersLSVT was delivered close to protocol: 13 hours 17 minutes of direct therapy on average against 2 hours 44 minutes for standard NHS speech therapy, usually by two or more therapists. The authors say that dosage gap may itself explain the trial result.
• SLPSystematic Review2023Sex and Race Representation in Temporal Bone Histopathology Studies in the United States: A Systematic Review.Ear and hearingMost US temporal bone studies never report the race of the people they examined: 15 of 300 did, and 11 of those 12 had fewer than 34% non-White donors. Sex was reported in 166 of 300 studies.
• SLPOther2023Functional Analysis of Injectable Substance Treatment on Surgically Injured Rabbit Vocal Folds.Journal of voice : official journal of the Voice FoundationNo injectable tested in this rabbit study clearly beat saline on vocal fold function: expert ratings of vibration found no significant group differences. Dexamethasone and hyaluronic acid/gelatin lowered fundamental frequency versus saline, which the authors read as softer tissue. Three larynges per group.
• SLPOther2026Hearing Aids Reshape Neural Processing of Emotional Speech Without Improving Emotion Perception.Trends in hearingHearing aids did not help older adults with hearing loss notice when the emotion in speech changed any better than listening unaided, and both were worse than normal-hearing peers. Aided listening did change which brain areas were engaged. Only 14 hearing-aid users were tested.
