• SLPCohort2022A longitudinal study of the phonological organisation of novel word forms in children with developmental language disorder.International journal of speech-language pathologyChildren with DLD persistently struggle to organise novel sound sequences into stable patterns over two years, even as their basic sound accuracy improves. Unlike typical peers, their speech variability does not converge with norms, suggesting sequencing deficits are a core, lasting feature of the disorder.
• SLPCohort2021Speech Development Between 30 and 119 Months in Typical Children II: Articulation Rate Growth Curves.Journal of speech, language, and hearing research : JSLHRTypically developing children show wide variation in articulation rate. By age 4, the 5th percentile is 2.5 syllables per second. By age 10, the 5th percentile is 3.0 syllables per second. Rates increase with age and utterance length, but most children take years to reach adult speeds.
• SLPRCT2021Toward Preventing Speech and Language Disorders of Known Genetic Origin: First Post-Intervention Results of Babble Boot Camp in Children With Classic Galactosemia.American journal of speech-language pathologyInfants with classic galactosemia receiving early parent-coached speech intervention showed faster growth in babble complexity and larger expressive vocabularies than untreated peers. At follow-up, most treated children had typical articulation and language scores, unlike untreated controls.
• SLPCohort2022Home language maintenance in bilingual children with normal hearing and with hearing loss who use cochlear implants.Clinical linguistics & phoneticsBilingual children with cochlear implants kept their home language, Spanish, but less than matched peers with normal hearing. Both groups retained more than half of Spanish items over time. Maternal education was linked to better maintenance in the implant group.
• SLPOther2021Which cognitive and linguistc factors influence phonological processing in adolescents?CoDASIn adolescents, rapid naming speed and phonological awareness are tightly linked to executive functions and attention, not just reading history. Slower object naming predicts lower working memory scores. Assessing these cognitive factors is essential when evaluating language difficulties in this age group.
• SLPOther2021Comparison of performance with hearing aid programmed to NAL-NL1 first-fit and optimized-fit.CoDASOptimizing a hearing aid to NAL-NL1 targets with probe-microphone verification improved soft-sound audibility by 10 dB and raised Kannada word scores by 7% versus manufacturer first-fit in 11 adults.
• SLPOther2022Understanding Self-reported Hearing Disability in Adults With Normal Hearing.Ear and hearingIn adults with normal audiograms, self-reported hearing difficulty scores were associated with speech audibility, temporal processing, and impulse-noise history; the model accounted for 41% of the spread in scores.
• SLPOther2022Diotic and Antiphasic Digits-in-noise Testing as a Hearing Screening and Triage Tool to Classify Type of Hearing Loss.Ear and hearingAntiphasic digits-in-noise testing detects unilateral or conductive hearing loss better than standard diotic testing. A two-step screening process classified hearing types with reasonable accuracy, helping triage patients who need medical referral versus those who can proceed with standard audiometric or over-the-counter care.
• SLPOther2021Development and Evaluation of a Language-Independent Test of Auditory Discrimination for Referrals for Cochlear Implant Candidacy Assessment.Ear and hearingHigher scores on a game-based nonsense-syllable test went with better sentence perception in noise among 81 English-speaking adults using hearing aids or cochlear implants. The test may help estimate likelihood of better discrimination with a cochlear implant, but needs other-language testing.
• SLPCohort2021Phonological productive processes in full-term schoolchildren and small for gestational age: a case-control study.CoDASSchool-age children born small for gestational age showed more unexpected speech sound errors affecting syllable structure than those born appropriate for gestational age. However, the study found no overall statistical association between being small for gestational age and having a speech sound disorder.
• SLPOther2021Language profile of children from a quilombola community.CoDASQuilombola preschoolers showed adequate vocabulary but impaired phonology and verbal short-term memory. Most five-year-olds retained phonological processes beyond expected ages, and none performed adequately on memory tasks. Functional communication was preserved, but school readiness risks were identified.
• SLPOther2022Predictive Sentence Context Reduces Listening Effort in Older Adults With and Without Hearing Loss and With High and Low Working Memory Capacity.Ear and hearingListening to sentences with predictable endings frees up mental resources for older adults, even those with hearing loss or low working memory. Clinicians should encourage communication partners to use clear, predictable context to reduce listening fatigue.
• SLPOther2022Updating sentences lists for assessment speech perception.CoDASReviewers identified predictability as the main reason to modify Brazilian Portuguese sentences for speech tests. The updated lists were tested on three normal-hearing adults, who scored nearly perfect. This is a tool development study, not evidence of clinical effectiveness.
• SLPOther2022Hesitations and relative proeminence in prosodic constituents in children's speech.CoDASIn 24 typical children, hesitations were more often in less prominent parts of speech units than in prominent parts, but they also appeared in prominent parts.
• SLPOther2022Adherence to Remote Microphone System use at school in children and adolescents with hearing loss.CoDASOf 120 students with hearing loss using a hearing aid or cochlear implant plus a remote microphone system, 54% used the system at school. Twenty-two percent did not use it because of problems beyond their control, and elementary students showed the highest use.
• SLPPilot2022Picture Description in the Assessment of Connected Speech Intelligibility in Parkinson's Disease: A Pilot Study.Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP)Picture description is feasible for assessing speech intelligibility in Parkinson's disease. Listeners understood speakers better when shown the picture. However, scores varied widely between individuals, suggesting this method complements rather than replaces standard reading tests.
• SLPOther2022Segmental acquisition of Brazilian Portuguese: onset simple, complex and coda.CoDASBrazilian Portuguese children typically produce simple consonants well by age 3, liquids and the tap by 4.6, and complex onsets by 6.0 to 6.6. Use these ages and expected correct speech production to spot possible delays.
• SLPCase Report2022Effects of Transcranial Direct Current Stimulation in writing: a case report of deep agraphia.CoDASOne man with deep agraphia improved writing after five sessions of dictation paired with brain stimulation. Gains in sound-based spelling held at five months, but word-shape spelling reverted. This shows what happened to one person, not that the treatment works.
• SLPOther2022Word and pseudoword reading in young adults: an eye-tracking study.CoDASEye-tracking showed skilled readers looked longer at pseudowords, long words, and low-frequency words. People with better verbal fluency had shorter first fixations on long words. These patterns suggest eye-tracking could help detect mild reading deficits, though no patients were tested.
• SLPOther2022Spelling abilities of school-aged children with Williams syndrome.Research in developmental disabilitiesChildren with Williams syndrome who learned to read through systematic phonics spelled significantly better than those taught other ways. Spelling ability was strongly linked to reading skill, even after accounting for IQ, suggesting spelling instruction may support literacy development.
• SLPOther2022Acoustic characteristics of fricatives, amplitude of formants and clarity of speech produced without and with a medical mask.International journal of language & communication disordersSpeech produced with surgical or KN95 masks had significantly lower amplitude for fricatives like /s/ and /ʃ/ and was rated as less clear by experts. Vowel formant amplitudes did not change. Clinicians should expect reduced fricative energy when wearing masks.
• SLPPilot2021Alveolar Backing in 3-Year-Old Children with and without Repaired Cleft Palate: Preliminary Findings Related to Cleft Type and History of Otitis Media.Perspectives of the ASHA special interest groups3-year-old children with repaired complete cleft lip and palate produced tongue-tip sounds, especially /s/, farther back in the mouth more often than children with palate-only clefts. This pattern was uncommon in the other groups, so listen for these backed productions.
• SLPOther2022The Challenge of Achieving Greater Generalization in Phonological Treatment of Aphasia.AphasiologyPhonological path distance between trained and untrained words did not predict naming improvement in people with aphasia receiving Phonomotor Treatment. The untrained words may have been too far from the training targets to benefit from intrinsic generalization.
• SLPPilot2022A serious game for speech training in dysarthric speakers with Parkinson's disease: Exploring therapeutic efficacy and patient satisfaction.International journal of language & communication disordersRatings rose after game training, but the gain was small and preferences were mixed. The study was small and did not separate the game from participants' other Parkinson's care.
• SLPOther2022Emotional Responses to Non-Speech Sounds for Hearing-aid and Bimodal Cochlear-Implant Listeners.Trends in hearingAdults with hearing loss rated everyday sounds as less pleasant and less unpleasant than normal-hearing peers, even with devices. Adding a hearing aid to a cochlear implant user’s other ear did not improve these emotional ratings and sometimes lowered them.
• SLPSurvey2022Perceived Listening Difficulties of Adult Cochlear-Implant Users Under Measures Introduced to Combat the Spread of COVID-19.Trends in hearingAdult cochlear implant users reported significantly worse listening during the pandemic, especially with face masks. They experienced high effort, fatigue, and anxiety, leading many to avoid communication. Visual cues like lipreading and captions were rated as the most helpful solutions.
• SLPOther2022Word Learning by Preschool-Age Children: Differences in Encoding, Re-Encoding, and Consolidation Across Learners During Slow Mapping.Journal of speech, language, and hearing research : JSLHRChildren with poorer working memory and vocabulary start with weaker word forms but learn at the same rate as peers. They need more repetitions to reach mastery. Retention drops after one month. Practice tests did not prevent this forgetting.
• SLPPilot2022Cognitive Training to Enhance Aphasia Therapy (Co-TrEAT): A Feasibility Study.Frontiers in rehabilitation sciencesCombining naming therapy with computerized working memory training was feasible for six people with chronic aphasia, who completed all sessions. Trends suggested the working memory group had better generalization to daily conversation and severity scores, but the sample was too small to confirm this.
• SLPCase Series2022Treatment of the Linguistic and Temporal Components of Lexical Activation to Improve Word Retrieval in Aphasia.Frontiers in rehabilitation sciencesDelayed repetition treatment helped some people with aphasia, but only those whose word retrieval broke down specifically when they had to wait before speaking. For these patients, practicing repetition with a 5-second pause improved word access and general language scores.
• SLPOther2022The Effects of Hearing-Aid Amplification and Noise on Conversational Dynamics Between Normal-Hearing and Hearing-Impaired Talkers.Trends in hearingBackground noise made conversations slower, louder, more variable and more effortful. Hearing-aid amplification lowered speech level by 1.1 dB in quiet and made older hearing-impaired speakers start turns 41 ms sooner.
• SLPOther2022Graduate Student Clinicians' Perceptions of Child Speech Sound Errors.Perspectives of the ASHA special interest groupsGraduate students agreed with experts on 80.71% of accurate speech but only 54.27% of inaccurate speech. Use the 3-point scale for progress tracking, not diagnosis. Students need specific criteria and practice to judge errors reliably.
• SLPOther2022Immediate effect of different exercises in the vocal space of women with and without vocal nodules.CoDASFive minutes of tongue vibration or straw phonation immediately reduced vowel space in women with nodules or healthy controls. Overarticulation had no effect. These exercises may alter articulator positioning but do not prove improved communication.
• SLPOther2022Assessing and Modeling Spatial Release From Listening Effort in Listeners With Normal Hearing: Reference Ranges and Effects of Noise Direction and Age.Trends in hearingNormal-hearing listeners reported less listening effort when noise came from the side (135°) than from the front, with the benefit larger in difficult listening conditions. Age did not significantly change these effort ratings, though older listeners showed steeper effort increases in very difficult conditions.
• SLPOther2022The Effect of Stimulation Position and Ear Canal Occlusion on Perception of Bone Conducted Sound.Trends in hearingPlacing bone conduction devices on the condyle improved speech clarity and sound quality compared to the mastoid or temple. In-ear occlusion further boosted low-frequency hearing and intelligibility. Air conduction remained the clearest option overall.
• SLPOther2022Baseline pupil size encodes task-related information and modulates the task-evoked response in a speech-in-noise task.Trends in hearingBaseline pupil size reflects listening effort and task familiarity, not just resting state. In a speech-in-noise task, baselines constricted as trials progressed and differed by noise type. Ignoring baseline changes distorts how we interpret pupil dilation as a measure of cognitive load.
• SLPOther2022Spatio-temporal Integration of Speech Reflections in Hearing-Impaired Listeners.Trends in hearingHearing-impaired listeners struggle to ignore the direct sound when reflections arrive from different directions. They rely on loudness rather than spatial cues to focus on reflections, and many fail to process complex spatial-temporal sound patterns.
• OTSLPRCT2022The "Mirror Effect Plus Protocol" for acute Bell's palsy: A randomized controlled trial with 1-year follow-up.Clinical rehabilitationIn acute Bell's palsy, MEPP added to medication and counselling (mirror feedback, motor imagery, soft-tissue manipulation, mime therapy, neuromuscular retraining, motor learning principles) showed mixed facial symmetry results: House-Brackmann scores favoured it, but Sunnybrook scores did not differ.
• SLPOther2022Using word-picture verification to inform language impairment locus in chronic post-stroke aphasia.Frontiers in rehabilitation sciencesIn 16 people with chronic aphasia, word-picture verification scores tracked closely with standard comprehension tests. Errors differed from naming: more semantic errors occurred during verification, while phonological errors were higher during naming. This helps distinguish input from output deficits.
• SLPSurvey2022Focus of Attention in Voice Training.Journal of voice : official journal of the Voice FoundationSingers reported that voice teachers give slightly more instructions focused on the sound or image (50.83%) than on body movements (39.42%). Teachers use more body-focused cues for posture and tension, but more sound-focused cues for tone and articulation.
• SLPOther2022Intonational Variation in the North-West of England: The Origins of a Rising Contour in Liverpool.Language and speechThis paper describes linguistic features of the Scouse accent, not clinical findings. It analyzes how 32 speakers pronounce sentences, finding distinct rising intonation patterns in Liverpool compared to Manchester. There are no therapy outcomes or patient data to report.
• SLPCohort2022Effect of Wearing a Face Mask on Vocal Self-Perception during a Pandemic.Journal of voice : official journal of the Voice FoundationPeople who wore masks for work reported more vocal fatigue, throat discomfort, and difficulty coordinating speech and breathing than those who wore them only for essential errands. Both groups felt masks made speaking harder and reduced their ability to hear themselves clearly.
• SLPOther2023Are Acoustic Markers of Voice and Speech Signals Affected by Nose-and-Mouth-Covering Respiratory Protective Masks?Journal of voice : official journal of the Voice FoundationMasks change voice measurements, but not all equally. A surgical mask barely affects pitch, loudness, or jitter, though it still skews quality scores. A transparent mask alters nearly every acoustic marker, including formants and high-frequency energy. Match mask types across pre- and post-treatment recordings.
• SLPOther2022Fluency-related Temporal Features and Syllable Prominence as Prosodic Proficiency Predictors for Learners of English with Different Language Backgrounds.Language and speechArticulation rate predicted prosodic proficiency better than syllable prominence for learners from four language backgrounds. Adding prominence measures improved prediction slightly, but the benefit varied by native language. Duration was a key cue for Czech, Slovak, and Hungarian speakers, while pitch was best for Polish speakers.
• SLPOther2022A new dynamic word learning task to diagnose language disorder in French-speaking monolingual and bilingual children.Frontiers in rehabilitation sciencesA dynamic word-learning task accurately identified language disorder in children aged 4-6 but failed for those aged 7-8. The task did not penalize bilingual children, suggesting it is a promising screening tool for younger groups only.
• SLPOther2022Intraspeaker Priming across the New Zealand English Short Front Vowel Shift.Language and speechSpeakers unconsciously repeat the phonetic shape of their own recent vowels. A vowel produced with a high, front jaw position primes the next vowel to be high and front, even if it belongs to a different word or sound category. This effect fades within half a second.
• SLPOther2023Cross-Linguistic Trends in Speech Errors: An Analysis of Sub-Lexical Errors in Cantonese.Language and speechCantonese speech errors follow many patterns seen in English, like swapping single sounds. However, whole syllables slip far more often than in English, and consonants and vowels mix more freely. This suggests Cantonese speakers plan speech by syllable, not just by individual sound.
• SLPOther2023Classification of accurate and misarticulated /ɑr/ for ultrasound biofeedback using tongue part displacement trajectories.Clinical linguistics & phoneticsA simple ultrasound parameter tracking just two tongue points classified accurate versus misarticulated /r/ sounds with 88.5% accuracy. This matches the performance of complex full-tongue tracking, suggesting a simplified visual feedback display could reduce the cognitive load currently hindering therapy outcomes.
• SLPOther2023Construct validity of the focus on the outcomes of communication under six (FOCUS) total and profile scores for multilingual preschoolers: Considering functional speech skills.International journal of speech-language pathologyIn Jamaican Creole-English preschoolers, parent-reported communication participation scores lined up moderately with how understood children's speech was, but weakly with direct speech accuracy. Some participation areas did not track speech skills, so they add separate information.
• SLPOther2023Early diagnostic indicators of childhood apraxia of speech in young children with 7q11.23 duplication syndrome: preliminary findings.Clinical linguistics & phoneticsToddlers with 7q11.23 duplication syndrome showed less mature babble, fewer vocalizations, and limited consonant and vocalization diversity than typical toddlers, more closely resembling children later diagnosed with apraxia. These patterns may flag risk, but they did not confirm a diagnosis.
• SLPOther2023Comparing metrics for quantification of children's tongue shape complexity using ultrasound imaging.Clinical linguistics & phoneticsUltrasound measures of tongue shape complexity can distinguish simple vowels from complex liquids in both adults and children. However, individual sounds often overlap, so these metrics currently identify broad patterns rather than classifying specific speech errors.
