• SLPCohort2025Targeted Auditory Rehabilitation Employing Direct Audio Input in Children With Single-Sided Deafness Using a Cochlear Implant.Ear and hearingMost children with single-sided deafness using a cochlear implant achieved open-set speech recognition after targeted auditory training, but spatial hearing remained poor. Daily implant use correlated with better speech scores. No control group was used, so these outcomes reflect what happened with the protocol, not proof that it works.
• SLPPilot2025Exploring perception of coarticulatory cues in childhood apraxia of speech and residual speech sound disorders: A pilot study.Journal of communication disordersChildren with childhood apraxia of speech struggled to hear the difference between sounds when the context changed, unlike children with only an 'r' error. This suggests their perception of speech is impaired beyond just the sound they mispronounce.
• SLPOther2025A Novel Artificial-Intelligence-Based Reverberation-Reduction Algorithm for Cochlear Implants Enhances Speech Intelligibility and User Experience.Ear and hearingA new AI-based reverberation-reduction algorithm improved speech understanding in noisy rooms for cochlear implant users. The version targeting both early and late reflections gave an average 17% intelligibility gain. Users also preferred this setting, finding speech more natural and easier to listen to.
• SLPOther2025Articulatory Methods for the Study of Second Language Speech.Language and speechNo original study or outcomes are reported in this editorial overview of research methods for studying speech production in a second language.
• SLPMeta-Analysis2025Modeling the Relationship Between Listener Factors and Envelope Fidelity: A Pooled Analysis Spanning a Decade.Ear and hearingListeners with lower working memory improved their speech-in-noise scores when hearing aid processing caused less distortion. Those with higher working memory did not show this benefit. This suggests that reducing signal distortion may help patients with lower cognitive capacity more than those with higher capacity.
• SLPOther2025Developmental Changes in Speech Frequency Weighting in Children.Ear and hearingChildren aged 6 to 13 years rely increasingly on high-frequency speech cues as they mature, with importance weights for 2000 and 4000 Hz bands rising with age. Standard adult-based models overestimate children's speech access, suggesting clinical predictions need age-specific adjustments.
• SLPNarrative Review2025The psychometric status of child language assessment tools in South Africa's official languages.The South African journal of communication disorders = Die Suid-Afrikaanse tydskrif vir KommunikasieafwykingsOnly four child language tests for South Africa's official languages are validated, and none have current reference scores. Many tools remain incomplete, so therapists often lack ready ways to assess children's language.
• SLPCohort2025Beyond Prevalence: Understanding the Relationship Between Early Anatomic Factors and the Likelihood for Cleft Speech Characteristics.International journal of language & communication disordersChildren with bilateral cleft lip and palate or post-surgical fistulas had much higher odds of cleft speech characteristics at age 3. Wider clefts specifically predicted passive errors. These anatomic factors help identify which children need targeted speech therapy or fistula repair.
• SLPOther2025Deciphering the Language in Our DNA and Leveraging the Discoveries Toward Improved Outcomes: Introduction to the Forum.Journal of speech, language, and hearing research : JSLHRThis forum introduces how genetic research in speech and language can inform clinical practice. It highlights precision medicine approaches like early intervention and targeted therapies, while emphasizing that behavior is influenced by many factors beyond genetics alone.
• SLPOther2025Auditory skills and neural encoding in children with speech sound disorder.CoDASChildren with phonological speech disorder had more altered binaural integration on dichotic digit testing than typical peers. Temporal resolution and parent-reported auditory behavior did not differ, and brain response test results were unclear.
• SLPOther2025An Evaluation of the Temporal Integrator Processing Strategy for Cochlear Implants in Comparison to the Clinical Strategy and in Multi-Talker Noise.Ear and hearingCochlear implant recipients heard speech in noise just as well with a new strategy that removes half the electrical pulses. The main result was no improvement over standard settings, but the method cut estimated power use by up to 42%, which could extend battery life.
• SLPOther2026Self-Supervised App-Based Speech Training for Children With Speech Sound Disorder-A Single-Case Experimental Design Study.International journal of language & communication disordersFour Swedish children with speech sound disorder showed no clear improvement in targeted sounds after three weeks of home app training. Small trained-word gains occurred in some children, but the app's star feedback did not match clinicians' ratings.
• SLPOther2026The Role of Speech Reading During Visual Word Processing in Hearing Children: A Functional Magnetic Resonance Imaging Study.Journal of speech, language, and hearing research : JSLHRIn hearing children, brain regions active during silent lip-reading also light up when judging written word rhymes. However, the strength of this brain activity did not correlate with their standardized word reading scores, so the study does not link this specific neural mechanism to reading ability.
• SLPOther2026Apparent Talker Variability and Speaking Style Similarity Can Enhance Comprehension of Novel L2-Accented Talkers.Language and speechEnglish-speaking listeners understood a new Mandarin-accented talker better after hearing Mandarin-accented speech, but only when the test talker used casual speech. Simulated multiple talkers added a small benefit only when both exposure and test were casual.
• SLPCase-Control2026Vowel Production Associated with Cantonese Speakers of Parkinson's Disease.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)Cantonese speakers with Parkinson's disease produced vowels in a smaller, more crowded space than healthy controls, with greater distortion in moderate disease. This acoustic blurring likely reduces intelligibility, suggesting vowel-space metrics could guide therapy.
• SLPOther2026Maximising the Impact of Speech and Language Therapy for Children With Speech Sound Disorder (The MISLToe-SSD) Study: Developing a Core Outcome Set (COS) for Routine Data Collection From UK NHS Speech and Language Therapy Services.International journal of language & communication disordersUK speech and language therapists agreed on a core set of outcomes to track in routine practice. They selected increased intelligibility as the primary goal, measured by parent report, alongside six specific speech metrics using the DEAP assessment. This standardises data collection for future service evaluation.
• SLPCohort2026The Effect of Real Ear Target Deviations on SSQ and Speech Intelligibility in a Clinical Population.Trends in hearingHearing aids improved both speech scores and patient-reported outcomes. High-frequency under-amplification was linked to smaller gains in self-reported benefit, but did not predict speech recognition in quiet. Closer matching to targets above 4 kHz may help patients feel the difference, though the effect is modest.
• SLPSurvey2026Using Hearing Aids for Music: A UK Survey of Challenges and Strategies.Trends in hearingHearing aid users find aids helpful for music but struggle with distortion and lyrics, especially in live settings. Many remove their aids or switch to headphones for better sound. Audiologist discussions on music are rare and often unhelpful.
• SLPOther2026Vowel space change as a predictor of speech intelligibility gain in Down syndrome.Clinical linguistics & phoneticsIntelligibility change was mixed in 13 children with Down syndrome. Tighter vowel production and a larger vowel-space boundary were associated with intelligibility gains; qVSA change was not. The study did not test whether the speech enrichment program caused improvement.
• SLPCohort2026Oral language profiles and associated factors in children after neonatal arterial ischaemic stroke.Developmental medicine and child neurologyMore than half of children with neonatal stroke have language difficulties at age 7. Access to speech therapy depends on how obvious the deficit is, not how severe. Children with receptive or borderline problems are frequently missed and under-referred.
• SLPOther2026Phoneme Manner Types and Function and Content Words as Biomarkers for Different Types of Stutters in Speakers Who Continue to Stutter.International journal of language & communication disordersWhole-word repetitions occur almost exclusively on function words starting with vowels, while prolongations and part-word repetitions cluster on content words starting with specific consonants. Grouping all stutter types together hides these distinct patterns.
• SLPProtocol2026Protocol for a Systematic Review of Interventions Not Delivered by Speech and Language Therapists for Children With Speech Sound Disorders.International journal of language & communication disordersThis paper outlines the plan for a future systematic review of non-speech-therapist-led interventions for children with speech sound disorders. It contains no results, data, or conclusions, so there is nothing here to change clinical practice.
• SLPOther2026Does the Use of Crowdsourced Listeners Yield Different Speech Intelligibility Results Than In-Person Listeners for Typically Developing Children?Journal of speech, language, and hearing research : JSLHRCrowdsourced listeners scored child speech as less intelligible than in-person listeners, with the largest drop for children in the mid-range of clarity. This method underestimates performance compared to standard norms, so it should not replace clinical assessment for these patients.
• SLPOther2026Perceptual Outcome Measures for Supplementing Transcription Intelligibility in Speakers with Parkinson's Disease and Mild Dysarthria.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)Transcription intelligibility scores hit a ceiling in mild Parkinson's, hiding subtle speech changes. Rating how effortful it was to listen, or how severe the speech seemed, captured a wider range of differences. These measures tracked closely with clinical severity ratings, offering a more sensitive picture than accuracy alone.
• SLPOther2026Preliminary study of a Digital Brazilian Portuguese Speech Assessment Instrument: validity and reliability of imitation and naming tasks.CoDASA new digital tool for assessing Brazilian Portuguese speech sound disorders showed strong agreement with an established test and reliably distinguished children with disorders from those with typical development. It is currently validated only for naming and imitation tasks in children aged 4 to 9.
• SLPOther2026Variable Speech Cueing Effects in Talkers With Parkinson's Disease.American journal of speech-language pathologyMost talkers with Parkinson's did not improve their perceived speech severity with loud, clear, or slow cues, and many got worse. Baseline severity predicts response: those with moderate impairment benefit most, while those with strained voices often fail to improve.
• SLPOther2026Content validation of the Adapted Cycles Intervention Program (PROCICLOS-A) for children with Speech Sound Disorder - Activities.CoDASExpert judges rated PROCICLOS-A activities appropriate for children with speech sound disorder. This checks content only; it does not show the activities improve speech.
• SLPOther2026Do Adolescent Hearing Aid Users Prefer Digital Noise Reduction to Be Activated? Findings From the Laboratory and Home Environments.Ear and hearingAdolescents preferred digital noise reduction active in the lab but not in daily life. It did not improve speech recognition. They liked the smartphone control but rarely used it. Default activation is reasonable, but real-world benefit remains unproven.
• SLPMeta-Analysis2026The Effectiveness of Ultrasound Visual Biofeedback in Articulation Therapy for Children and Adolescents With Speech Sound Disorders: A Systematic Review and Meta-Analysis.International journal of language & communication disorders26 of 35 studies reported better speech accuracy in children and adolescents with speech sound disorders who received ultrasound visual biofeedback with or alongside traditional therapy, motor-based approaches, electropalatography, or auditory perception training. Results varied widely.
• SLPCase-Control2026Multidomain Developmental Indicators in 4- to 9-Year-Old Children with Oral Motor and Speech Sound Disorders.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)Children with oral motor and speech sound disorders more often had adenoid surgery, pulmonary disease, selective eating, mouth chewing, delayed motor and crawling milestones, no canonical babble, concentration issues, and family speech or literacy delay. These were links, not proof of cause.
• SLPOther2026Predicting Spectro-Temporal Modulation Detection Thresholds With a Functional Auditory Model.Trends in hearingAn auditory model predicted group-average spectro-temporal modulation thresholds well but failed to predict individual differences in older hearing-impaired listeners. It underestimated the magnitude of their deficits, suggesting current models of cochlear damage do not fully explain supra-threshold processing issues.
• SLPOther2026A Speech-Segregation Algorithm for Spatial Hearing Aids to Operate With Multiple Sound Sources.Journal of speech, language, and hearing research : JSLHRThe algorithm improved automatic transcription of front placements of speech and noise, but removed target speech when sources were close on the side; no human listeners were tested.
• 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.
• SLPCase-Control2026Nonword Repetition Assessing Auditory and Cognitive Abilities in Adult Cochlear Implant Users.Journal of speech, language, and hearing research : JSLHRAdult cochlear implant users repeated significantly fewer nonwords than normal-hearing peers, especially after age 67. Poorer performance was predicted by reduced spectral resolution and weaker reading or vocabulary skills, not working memory, suggesting bottom-up auditory limits drive phonological difficulties.
• 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.
• 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.
• SLPOther2026Evidence for an integrated bilingual language system from discourse tasks in aphasia.AphasiologyIn 13 bilinguals with aphasia, error types were identical in both languages, but the weaker language had more errors. Switching into the stronger language was common. This supports a shared language system where the stronger language is easier to access.
• SLPOther2026The Link Between Syntactic Complexity and Stuttering-Like Disfluencies in French Speaking Adults.International journal of language & communication disordersIn 12 French adults who stutter, disfluencies rose with longer and more complex sentences, but the link was weak. Sentence length tracked disfluencies best. This did not test treatment.
• SLPCase Series2026Deep learning-derived measures of sound-level accuracy in primary progressive apraxia of speech: A feasibility pipeline with descriptive evidence from two cases.Clinical linguistics & phoneticsDeep learning measures of sound accuracy tracked the specific speech errors of two people with apraxia of speech. The tool distinguished between articulatory and timing subtypes in these cases, but results from delayed feedback and rate changes were inconsistent.
• SLPOther2026Sweet-Spot Compression: An Amplification Strategy for Improving Listening Outcomes at Moderate to High Levels.Trends in hearingAn experimental hearing aid setting that holds back gain for loud speech improved speech understanding in noise. At the highest speech level tested, scores were 8.1% better than with a standard fitting, and 10 of 17 participants preferred it in every condition.
• SLPCohort2026Pediatric CI 3-60 Guideline: When to Refer Children for a Cochlear Implant Candidacy Evaluation.Ear and hearingRefer a child for cochlear implant candidacy evaluation when the unaided four-frequency average is 60 dB HL or worse, aided SII is 0.60 or lower, or aided word recognition is 60% or poorer. At least 94% of ears recommended for implantation met one of these.
• SLPRCT2026Optimizing Sound Quality Improves Hearing Aid Users' Moods and Listening-Related Fatigue.Trends in hearingWhen hearing aids were set to the sound quality people liked best, their daily mood was better and their listening fatigue lower than with a merely tolerable setting. The benefit showed up only in the participants who still preferred that setting at home.
• SLPQualitative2026'Team Speech Sounds'-How Speech and Language Therapists Work With Parents of Young Children With Speech Sound Disorder: A Focus Group Study.International journal of language & communication disordersTherapists said the relationship with the parent is what makes home practice happen: setting expectations early, watching parents practise and giving feedback. Time and service limits get in the way, and many avoid watching or filming parents for fear of making them feel judged.
• SLPOther2026A Binaural Front End for Speech Intelligibility Models: Application to the Hearing-Aid Speech Perception Index (HASPI).Trends in hearingNot a clinical study. The paper builds and tests a signal-processing component for a computer model that predicts speech understanding in noise, checked against previously published headphone measurements from normal-hearing listeners.
• SLPCohort2026The Relation of Home Literacy Environment to Brain Specialization and Sensitivity for Phonological and Semantic Processing of Spoken Words.Journal of speech, language, and hearing research : JSLHRHome reading environment showed no strong link to how children's brains divided the work of processing sounds and word meanings. In older children only, being read to more often went with a stronger response when word pairs were only loosely related in meaning.
• SLPOther2026Impact of ageing on discourse types: a comparative study.CoDASOn conversation, narration and picture description tasks, older adults scored lower than younger and middle-aged adults. Picture description dropped most. Within the oldest group, conversation held up better than the other two.
• SLPCase Series2026Perception-production relationship in children with phonological disorder during speech therapy.CoDASChildren with phonological disorder scored far higher on perceiving speech, their own and other people's, than on producing the /l/ and /ɾ/ sounds. Seven of the sixteen had still not mastered those sounds at the end, and perception and production barely tracked each other.
• SLPSystematic Review2026Long-Term Speech Outcomes in Moderate-to-Severe Childhood Speech Sound Disorder: A Systematic Review.International journal of language & communication disordersThe studies differ too much in how they define severity, when they reassess and what they measure to answer whether, or when, a moderate-to-severe childhood speech sound disorder resolves. Persistence was common in childhood apraxia of speech and speech-plus-language difficulties.
• SLPOther2026Multidimensional Measurements of Dysarthria in Myotonic Dystrophy Type 1.International journal of language & communication disordersAdults with myotonic dystrophy type 1 spoke and articulated more slowly than reference values, could not reach normal loudness, and had a narrower pitch range. Most rated their own speech as fine. Relatives rated it lower as severity rose. Twenty-two patients, no control group.
• 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.
