• SLPCohort2023Opinion of speech-language pathologist on the use of photobiomodulation in the vocal clinic.CoDASBrazilian speech-language therapists widely report using photobiomodulation in voice practice, mostly before exercises, on the thyroid cartilage with 808-830 nm light. The paper describes their reported training and parameters, not whether photobiomodulation improves voice.
• PTOTSLPSystematic Review2023The Effects of Substance Misuse on Auditory and Vestibular Function: A Systematic Review.Ear and hearingSubstance misuse, particularly opioids and alcohol, is linked to hearing and balance problems in case reports. Opioid use often causes permanent, profound hearing loss. Alcohol misuse is associated with high-frequency hearing loss and central balance deficits. Evidence is weak and mostly anecdotal.
• SLPOther2023Predictors of Emotional Prosody Identification by School-Age Children With Cochlear Implants and Their Peers With Normal Hearing.Ear and hearingSchool-age children with cochlear implants identified spoken emotions less accurately than normal-hearing peers. Older age was linked to better scores in both groups. In children with implants, longer device use and higher problem-solving ability were linked to better scores.
• SLPOther2023Analysis of different performance times of the voiced trill technique in older women.CoDASThe voiced trill did not produce different immediate voice ratings in older women with and without self-perceived vocal changes, although judges most often rated voices as improved after 1 minute.
• SLPSurvey2023Proposal of requirements for the development of a training simulator for the auditory-perceptual judgment of voice.CoDASExperienced voice trainers mostly agree voice listening training should begin after early coursework, start by detecting vocal deviation, then identify dominant quality, then rate severity. Training hours, voices, scales, and effect checks varied widely.
• OTSLPCase-Control2024Acoustic and Semantic Processing of Auditory Scenes in Children with Autism Spectrum Disorders.Journal of autism and developmental disordersChildren with autism detected changes in complex sounds and understood speech in noise as well as peers matched for IQ, but worse than age-matched peers. Both groups used meaning and sound cues similarly, suggesting autism alone does not impair auditory scene processing.
• SLPCohort2023Future teachers and the self-perception of vocal symptoms and knowledge about vocal health and hygiene.CoDASFuture teachers reported high vocal symptoms but low knowledge of vocal hygiene. Symptoms peaked in first-year students, while knowledge improved in later years and with age. Prior voice guidance did not significantly reduce reported symptoms, suggesting current educational interventions may be insufficient.
• SLPSurvey2023Social distancing and choral singing during the Covid-19 pandemic: challenges and vocal symptoms of chorists.CoDASOlder choristers reported more voice problems during remote rehearsals. Younger choristers reported fewer throat symptoms but more anxiety about singing alone. Both groups struggled with concentrating on video calls and reduced practice time.
• SLPCase-Control2023Videofluoroscopic measures of swallowing in people with stable COPD compared to healthy aging.CoDASIn stable COPD, swallowing showed shorter airway closure, earlier and shorter upper esophageal sphincter opening, and weaker pharyngeal squeeze compared with matched healthy adults. Penetration-aspiration was absent, so these differences may raise aspiration risk.
• SLPCase Report2023Swallowing capacity and gravity of the laryngotracheal aspiration risk in atypical cerebellar stroke: case report.CoDASIn a single outpatient one year and five months after a cerebellar stroke, bedside swallowing screens found moderate dysphagia with aspiration risk. She had left mouth numbness, poor voluntary cough, and choking with liquids.
• SLPCohort2023Comparison between the acoustic fundamental frequency of the voice and the vibration frequency of the vocal folds analyzed by digital kymography.CoDASAcoustic voice frequency matches vocal fold vibration frequency measured by digital kymography in healthy adults. This confirms that standard acoustic tests accurately reflect laryngeal mechanics, supporting their use for monitoring voice function without needing complex imaging for basic frequency assessment.
• SLPCohort2024Prediction of dysphagia aspiration through machine learning-based analysis of patients' postprandial voices.Journal of neuroengineering and rehabilitationA machine learning model analyzing post-meal voice recordings distinguished aspiration from normal swallowing with an average accuracy score of 0.83. This offers a potential non-invasive screening tool, though it requires further validation before clinical use.
• SLPOther2023VoxMore: technological artifact to assist voice acoustic evaluation in the teaching-learning process and clinical practice.CoDASA new Praat plugin called VoxMore was developed to generate detailed acoustic voice reports for teaching and clinical use. It visualizes voice signals across time, frequency, and cepstral domains. No patient outcomes or diagnostic accuracy were tested.
• SLPOther2023Cross-cultural adaptation to Brazilian Portuguese of the Vocal Congruence Scale and Transgender Congruence Scale.CoDASThe Vocal Congruence Scale and Transgender Congruence Scale were successfully adapted into Brazilian Portuguese. A pre-test with 38 transgender individuals showed that all items were understood and applicable, providing clinicians with usable tools for assessment.
• SLPPilot2024Plug-and-Play Microphones for Recording Speech and Voice with Smart Devices.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)Consumer plug-and-play microphones matched the reference microphone only for pitch and vowel formant movement. They did not reliably measure most other speech features, and group differences became weaker, so use the same microphone throughout.
• PTOTSLPCohort2024Longitudinal Analysis of Dysphagia and Factors Related to Postoperative Pneumonia in Patients Undergoing Esophagectomy for Esophageal Cancer.DysphagiaAfter esophagectomy, pharyngeal residue and vocal fold immobility worsened, with residue linked to pneumonia. Hyoid movement and vocal fold issues persisted at three months, though all patients returned to a full diet and no aspiration occurred.
• SLPOther2024Validation and Development of Voice Handicap Index-Throat for Koreans.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)The Korean Voice Handicap Index-Throat reliably measures throat symptoms alongside voice issues. It distinguished patients from healthy controls and scored highest in those with primary throat problems, helping clinicians separate voice complaints from throat complaints.
• SLPPilot2023Immediate effects of the incentive spirometer in women with healthy voice.CoDASUsing an incentive spirometer in 22 vocally healthy women immediately improved some voice stability measures and maximum expiratory volume. Listeners judged half the voices unchanged. The study did not test people with voice disorders.
• SLPCohort2023Spectral and cepstral measurements in women with behavioral dysphonia.CoDASIn 146 women with behavioral dysphonia, cepstral measures (CPP and CPPS) tracked hoarseness severity and distinguished breathy from rough voices. Spectral slope (H1-H2) differed between those with and without nodules. Spectral decrease did not separate groups or correlate with strain.
• SLPOther2024Acoustic Analysis of Swallowing of an Experimental Meal of Three Food Textures: A Comparative Aging Study.DysphagiaNumber of swallows and average swallow duration did not differ between adults 50 to 70 and over 70. Over a three-texture meal, older adults had longer gaps between swallows, longer meal time, and fewer swallows per minute.
• SLPCase Report2023Clinical Case Study: Pediatric Bilateral Benign Vocal Fold Lesions.Perspectives of the ASHA special interest groupsA 4-year-old boy with benign vocal fold lesions completed six voice therapy sessions over 12 weeks. Follow-up imaging showed smaller lesions and better vocal fold closure, while voice quality scores improved from moderate to mild dysphonia.
• SLPOther2023Voice and Communication Training Program Improves Performance of University Students in Oral Presentations.CoDASAfter an eight-week training covering voice, body language, social skills, neuro-linguistic programming, and language, 38 students improved by examiner and self ratings. Single group, so components cannot be separated.
• SLPOther2023Self-perception of the Immediate Impact on the Voice of Gospel Singers after a one-hour Presentation.CoDASGospel singers with existing vocal complaints reported significantly higher fatigue and difficulty singing after one-hour performances. Even those without complaints showed signs of vocal strain, suggesting all amateur singers may benefit from post-performance vocal care guidance.
• SLPCohort2023Prevalence of hearing loss and health vulnerability in children aged 25 to 36 months: an analysis of spatial distribution.CoDASNo significant link was found between hearing loss and health vulnerability in 95 Brazilian toddlers. However, 48.4% failed screening, yet nearly half did not attend the follow-up diagnostic assessment, leaving the true prevalence of hearing loss unknown.
• SLPOther2023Modifications of auditory feedback and its effects on the voice of adult subjects: a scoping review.CoDASMasking your own voice with noise tends to make adults speak louder; amplifying it tends to make them speak softer. Pitch shifts trigger reflexive pitch corrections. This is a scoping review of experiments, not evidence that a voice therapy works.
• SLPOther2023Cross-cultural adaptation of the Dysphonia Screening Tool (DST-Br) for European Portuguese (EP).CoDASThe Dysphonia Screening Tool was adapted into European Portuguese using two simple yes/no questions about voice strain and hoarseness. Thirty people with dysphonia understood the items without needing a 'not applicable' option. This version requires formal validation before clinical use.
• SLPSurvey2024Self-perception of voice, hearing, and general health in screening for voice changes in older women.CoDASAmong 95 older women, 44 screened positive for voice disorders. These women rated their voice, hearing, and general health worse than those who screened negative. They also reported more sore throats, sinusitis, and respiratory allergies. Age, education, smoking, and hydration were not linked to the screening result.
• SLPOther2023Quantifying the Occupational Voice Use of Teachers.Perspectives of the ASHA special interest groupsFemale teachers used their voice 16.2% of monitored time during work and 8.2% off work. Teachers with voice disorders did not differ from healthy teachers in vocal dose measures.
• SLPCase Report2024Intensive Voice Treatment following Botulinum Neurotoxin Injection for a Speaker with Abductor Laryngeal Dystonia: An Exploratory Case Study.Seminars in speech and languageIn one woman with abductor laryngeal dystonia whose voice had not improved after botulinum injections, intensive teletherapy was followed by increased sustained vowel time, better perceived voice quality, and a normal voice handicap score by 3 months.
• PTOTSLPQualitative2024Barriers to healthcare and a 'triple empathy problem' may lead to adverse outcomes for autistic adults: A qualitative study.Autism : the international journal of research and practiceAutistic adults described a 'triple empathy problem' where communication breaks down due to autism-specific differences, general doctor-patient mismatches, and medical culture. Barriers like sensory overload and phone-only appointments led to healthcare avoidance and severe, self-reported adverse outcomes.
• SLPOther2024Correspondence between consonant inventories obtained using modified naturalistic listening in real time (NLRT) and parent report.Journal of communication disordersParent report and modified naturalistic listening agreed on only 13% of toddlers' consonant inventory sizes. Parents missed the glottal [h] and glides, but agreed with coders on 87% of stops, the category clinicians watch for velopharyngeal closure post-surgery.
• PTOTSLPSystematic Review2024Hope as experienced by people with acquired brain injury in a rehabilitation-or recovery process: a qualitative systematic review and thematic synthesis.Frontiers in rehabilitation sciencesHope after brain injury is a double-edged sword: it drives recovery but can cause despair when unfulfilled. Patients need therapists to make small progress visible, set realistic goals, and balance honesty with support. The therapeutic alliance is crucial for maintaining hope.
• PTOTSLPCohort2023Sex differences in the age of childhood autism diagnosis and the impact of co-occurring conditions.Autism research : official journal of the International Society for Autism ResearchIn 1438 children diagnosed with autism, boys were diagnosed earlier than girls, but that sex difference did not remain after other diagnoses were included. Speech, audiology, and physical or occupational therapy visits were linked to earlier diagnosis.
• SLPPilot2024Swallowing and feeding of young children on high-flow oxygen therapy.The South African journal of communication disorders = Die Suid-Afrikaanse tydskrif vir KommunikasieafwykingsMost young children on high-flow oxygen tolerated pureed and semi-solid foods safely. Thin liquids triggered coughing and aspiration signs in four children. Chewing was often too tiring. Start with thicker textures and monitor closely, as this small study cannot prove safety for all patients.
• SLPCohort2024Prelingually Deaf Children With Cochlear Implants Show Better Perception of Voice Cues and Speech in Competing Speech Than Postlingually Deaf Adults With Cochlear Implants.Ear and hearingPrelingually deaf children with cochlear implants outperformed postlingually deaf adults in perceiving voice cues and separating speech in competing speech. Children used both pitch and vocal tract length cues, unlike adults who relied mainly on pitch. This suggests early implantation aids the brain in interpreting degraded signals.
• SLPOther2024The influence of listener experience, measurement scale and speech task on the reliability of auditory-perceptual evaluation of vocal quality.CoDASReliability of voice ratings depends on the task and scale, not just experience. CAPE-V sentences showed the highest agreement among all listener groups, while sustained vowels were least reliable. Standardized training improved agreement more than years of clinical experience did.
• SLPOther2024(Why) Do Transparent Hearing Devices Impair Speech Perception in Collocated Noise?Trends in hearingTransparent hearing devices made normal-hearing listeners need a slightly worse signal-to-noise ratio to understand speech in same-direction noise. The effect was small, about 0.5 to 1 dB for most devices. Listening effort did not show a clear change. One earphone showed no impairment.
• SLPNarrative Review2024Impaired oral health: a required companion of bacterial aspiration pneumonia.Frontiers in rehabilitation sciencesPoor oral health and plaque biofilms are a required pillar of bacterial aspiration pneumonia in at-risk patients. Daily toothbrushing and organized professional oral care may reduce pneumonia, febrile days, and death.
• SLPOther2024Validity of Acoustic Measures Obtained Using Various Recording Methods Including Smartphones With and Without Headset Microphones.Journal of speech, language, and hearing research : JSLHRSmartphone recordings produced voice measures that closely tracked a research microphone across 24 samples. Direct phone recording did not differ from the standard for CPP and L/H ratio. Still, microphone and room noise changed some values, so do not mix devices when tracking progress.
• SLPCohort2024The Effectiveness of Slightly Thick Liquids for Improving Swallowing in Bottle-Fed Children With Aerodigestive Concerns.Perspectives of the ASHA special interest groupsSlightly thick liquids did not significantly reduce penetration frequency in bottle-fed children with swallowing concerns. While they lowered the amount of penetration seen, they increased sucking effort and pharyngeal residue, suggesting a trade-off between safety and efficiency.
• SLPOther2024Cepstral Peak Prominence Smoothed - CPPS and Acoustic Voice Quality Index - AVQI in healthy and altered children's voices: comparation, relationship with auditory-perceptual judgment and cut-off points.CoDASAcoustic measures CPPS and AVQI successfully distinguish healthy from deviated voices in children. Children with voice disorders had lower CPPS and higher AVQI scores. The study provides specific cut-off values for these tests to help clinicians identify vocal issues in pediatric patients.
• SLPPilot2023Traditional and Visual-Acoustic Biofeedback Treatment via Telepractice for Residual Speech Sound Disorders Affecting /ɹ/: Pilot study.Perspectives of the ASHA special interest groupsSeven children with persistent /ɹ/ distortions completed 20 telepractice sessions combining visual-acoustic biofeedback and motor-based treatment. Six showed clinically meaningful improvement, but the design cannot separate which component drove the gains.
• SLPOther2024Immediate effect of inspiratory exercise with exerciser and respiratory encourager in women without vocal complaints.CoDASA single inspiratory exercise session increased maximum phonation time for the /s/ sound but produced no immediate changes in vocal quality or acoustic measures. It does not serve as a vocal warm-up for improving voice stability.
• SLPOther2024Cross-cultural adaptation of the Voice-related Experiences of Nonbinary Individuals - VENI to Brazilian Portuguese.CoDASThe Brazilian Portuguese VENI voice questionnaire was pre-tested with 21 nonbinary people, and standard responses were more common than non-applicable responses for every item. It can help speech therapists ask about voice experiences.
• SLPCase Report2024Ultrasonographic analysis of the hyoid bone distance in individuals with neurogenic oropharyngeal dysphagia.CoDASUltrasound showed the hyoid bone moved less upward during swallowing in adults with neurogenic oropharyngeal dysphagia than in healthy adults. Food consistency did not change the measurement.
• SLPOther2024Cross-cultural adaptation of the Iranian Voice Quality of Life Profile into Brazilian Portuguese.CoDASThe Iranian voice quality-of-life questionnaire was adapted into Brazilian Portuguese. Thirty-six adults at risk for dysphonia understood all 43 items, and no item needed change. It is not yet validated, so it should not be used as a validated measure.
• SLPCohort2024Elderly people with hearing loss and cognitive decline: speech perception performance in noise.CoDASCognitive decline did not worsen speech-in-noise perception in elderly people with hearing loss. Instead, the degree of hearing loss and education level determined performance. Clinicians should prioritize audiological and educational factors over cognitive status when assessing these patients.
• SLPSurvey2024Vocal risk mapping in classical singers: an analysis of the self-perception of voice quality, vocal fatigue, and singing voice handicap.CoDASClassical singers reported low overall voice handicap but higher vocal fatigue and avoidance when they used their voices to demonstrate examples for students. Cool-down practices were also associated with higher restriction scores. This suggests that teaching demands, not just singing, drive perceived vocal strain.
• SLPOther2024The role of the age and gender, and the complexity of the syntactic unit in the perception of affective emotions in voice.CoDASLatvian listeners recognized angry voices at 84.9%, happy voices at 67.4%, and neutral voices at 73.2%. Older listeners were less accurate for angry and happy voices. Phrases helped angry recognition; paragraphs helped happy and neutral recognition.
• SLPOther2024Word and Gender Identification in the Speech of Transgender Individuals.Journal of voice : official journal of the Voice FoundationWhen trans women's speech was altered to have a gender-neutral pitch, listeners confused the words more often. Tokens identified as the wrong word were rated less feminine, suggesting listeners use perceived gender to guess the intended vowel.
