• SLPOther2025Electrophysiological Responses to Spectral Ripple Envelope Phase Inversion in 3-Month-Olds and Adults.Ear and hearingIn 3-month-olds and adults, the acoustic change complex was detected in response to the 1 ripple-per-octave change but rarely to the 8 ripple-per-octave change. This supports it as a possible objective probe of infant auditory discrimination.
• SLPNarrative Review2026Avoiding unintended consequences: science of reading policies may harm deaf children.Journal of deaf studies and deaf educationNo new study data are reported. The paper reviews prior evidence and warns that one-size-fits-all phonics policies can harm deaf children.
• SLPCohort2026Cortical Auditory Neural Responses to Speech and Communicative Functioning in Normocephalic Children With Prenatal Exposure to the Zika Virus.Ear and hearingDirect language tests did not separate exposed and non-exposed children. Caregivers reported lower everyday communication and socialization in exposed children. Brain responses sorted speech sounds at different stages.
• SLPOther2026On the Use of Hearing Aid Algorithms in Industrial Noise: Balancing Speech Intelligibility and Hearing Protection.Trends in hearingListeners with hearing loss understood speech better when compression amplification was added to protection in factory noise, but it raised exposure at the lower noise level. Adding noise reduction lowered exposure without further intelligibility change. Normal-hearing listeners showed no intelligibility benefit.
• SLPCase-Control2017Interarticulator coordination in children with and without cerebral palsy.Developmental neurorehabilitationChildren with cerebral palsy moved their lips and jaw less smoothly together than typical peers, especially in timing. Simple sentences gave the most coordination, not fast repeated buh.
• SLPOther2017Children perceive speech onsets by ear and eye.Journal of child languageSeeing a talker's mouth moving helped children from four to fourteen name pictures faster in a lab task, especially when the heard onset was incomplete. The visual help was strongest for unfamiliar nonwords.
• SLPOther2017Effect of Training and Level of External Auditory Feedback on the Singing Voice: Pitch Inaccuracy.Journal of voice : official journal of the Voice FoundationProfessional singers had better pitch accuracy than non-professionals. Fast tempo, staccato, and descending phrases increased pitch error in both groups. Unexpectedly, blocking external hearing with protectors improved non-professionals' accuracy, while professionals remained unaffected by the change.
• SLPCohort2017Longitudinal development of communication in children with cerebral palsy between 24 and 53 months: Predicting speech outcomes.Developmental neurorehabilitationChildren with cerebral palsy who were not yet talking at age 2 were highly likely to remain unable to speak at age 4. For those who did begin speaking, earlier onset predicted faster gains in intelligibility and sentence length. Later starters showed persistent speech difficulties through preschool.
• SLPOther2017Phonological encoding in speech-sound disorder: evidence from a cross-modal priming experiment.International journal of language & communication disordersChildren with speech sound disorder did not show the predicted naming speed benefit from words that share the picture ending. They were faster than typical peers relative to the neutral tone, but this did not support the idea that their sound planning was less mature.
• SLPNarrative Review2017Human Speech: A Restricted Use of the Mammalian Larynx.Journal of voice : official journal of the Voice FoundationRoutine low-pitch speech may underuse laryngeal muscles, a theoretical voice review proposes. It reports no new patients or outcomes.
• SLPOther2016Deriving gradient measures of child speech from crowdsourced ratings.Journal of communication disordersCrowdsourced ratings from nine untrained listeners accurately measure gradient speech errors like covert /r/ contrasts. Binary and visual analog scales produce equally valid results, but binary ratings are faster. This offers a practical alternative to acoustic analysis or expert panels for assessing speech development.
• SLPOther2017The Benefits of Increased Sensation Level and Bandwidth for Spatial Release From Masking.Ear and hearingSpeech recognition thresholds improved when the target was at a higher level and when competing talkers were spatially separated. When audibility was equated across frequencies, bandwidth also helped, but this was a lab study, not hearing aid fitting.
• SLPOther2017Gradient perception of children's productions of /s/ and /θ/: A comparative study of rating methods.Clinical linguistics & phoneticsAdult listeners' line ratings of children's /s/ and /θ/ productions varied across the whole scale and tracked how a group heard the sounds. A single rating line may capture fine sound detail that a simple /s/ or /θ/ choice misses.
• SLPOther2017The Acoustics of Word-Initial Fricatives and Their Effect on Word-Level Intelligibility in Children With Bilateral Cochlear Implants.Ear and hearingChildren with cochlear implants produced /s/ and /ʃ/ with less acoustic contrast than hearing peers. In noise, their /s/ words were harder to understand than their /ʃ/ words, but there was no significant difference between the two groups for either sound alone.
• SLPOther2016The Influence of Cochlear Mechanical Dysfunction, Temporal Processing Deficits, and Age on the Intelligibility of Audible Speech in Noise for Hearing-Impaired Listeners.Trends in hearingHearing-impaired adults did not struggle in speech-in-noise for one reason. Steady-noise difficulty tracked residual cochlear compression. Two-talker difficulty tracked temporal processing. Age affected both, beyond thresholds and ear mechanics.
• SLPOther2016Sentence Recognition Prediction for Hearing-impaired Listeners in Stationary and Fluctuation Noise With FADE: Empowering the Attenuation and Distortion Concept by Plomp With a Quantitative Processing Model.Trends in hearingA hearing model predicted speech recognition thresholds in noise better than the standard SII method, especially in fluctuating noise and when a second noise test was used to correct each person’s distortion. This is a modelling result, not a clinical decision tool.
• SLPOther2016Perception of Interaural Phase Differences With Envelope and Fine Structure Coding Strategies in Bilateral Cochlear Implant Users.Trends in hearingFS4 did not produce a larger binaural speech-in-noise benefit than HDCIS: 0.6 dB with FS4 and 0.5 dB with HDCIS, versus 7.5 dB in normal-hearing listeners.
• SLPOther2016Self-perceived competence and social acceptance of young children who stutter: Initial findings.Journal of communication disordersFour- and five-year-olds who stutter did not rate their general competence or social acceptance lower than fluent peers. However, children who stuttered more often reported feeling less socially accepted, and girls rated competence higher than boys.
• SLPOther2017Mapping Common Aphasia Assessments to Underlying Cognitive Processes and Their Neural Substrates.Neurorehabilitation and neural repairCommon aphasia tests often measure several language and cognitive processes at once. In 38 people after left hemisphere stroke, naming tasks tracked word finding, but some WAB subtests relied on more than one process, so single scores need broader interpretation.
• SLPOther2016Rapid Release From Listening Effort Resulting From Semantic Context, and Effects of Spectral Degradation and Cochlear Implants.Trends in hearingSemantic context can reduce listening effort while hearing a sentence, but degraded speech delays that relief. People using cochlear implants showed some benefit, though it arrived later than in normal hearing.
• SLPOther2016Aging and Spectro-Temporal Integration of Speech.Trends in hearingOlder adults with normal hearing integrated fragmented speech as well as younger adults in this lab test. Age did not reduce performance across most conditions. Only the mid-age group had an unexplained drop when bands were split between ears.
• SLPOther2016A Binaural Grouping Model for Predicting Speech Intelligibility in Multitalker Environments.Trends in hearingA model using binaural cues predicted how spatial separation helps hearing speech in noise. It matched the measured pattern, but predicted 3 to 4 dB more benefit than measured.
• SLPNarrative Review2016Nexus to Lexis: Phonological Disorders in Children.Seminars in speech and languageNo original findings are reported. This is a theoretical review of phonological disorders in children.
• SLPOther2016Assessment of Spectral and Temporal Resolution in Cochlear Implant Users Using Psychoacoustic Discrimination and Speech Cue Categorization.Ear and hearingIn cochlear implant users, better speech frequency-cue categorization went with a non-speech frequency ripple test and word recognition. Better speech timing-cue categorization also went with word recognition, but a non-speech timing test did not.
• SLPOther2016Phonological Priming in Children with Hearing Loss: Effect of Speech Mode, Fidelity, and Lexical Status.Ear and hearingSeeing a talking face increased picture naming speed when children also heard a related distractor. The visual speech benefit occurred in both hearing-loss and normal-hearing groups. Better auditory word recognition was linked to more benefit in hearing loss.
• SLPOther2016Psychometric Functions of Dual-Task Paradigms for Measuring Listening Effort.Ear and hearingSecondary-task reaction time did not simply worsen as speech got harder. It peaked at intermediate difficulty and shortened at very poor noise levels, in younger and older listeners.
• SLPOther2017Quality ratings of frequency-compressed speech by participants with extensive high-frequency dead regions in the cochlea.International journal of audiologyFrequency-compressed speech was usually rated slightly worse than the reference hearing aid sound by five people with high-frequency dead regions. Quality was worse when compression started below the dead region limit or used a ratio of 4.
• SLPSurvey2016Addressing phonological memory in language therapy with clients who have Down syndrome: Perspectives of speech-language pathologists.International journal of language & communication disordersSpeech-language pathologists who worked with clients with Down syndrome were least likely to address memory for speech sounds, compared with clients with specific language impairment or autism. Almost half addressed it occasionally or regularly.
• SLPPilot2017An exploratory study of the influence of load and practice on segmental and articulatory variability in children with speech sound disorders.Clinical linguistics & phoneticsRetrieval made lip and jaw movement more variable than imitation in all nine children. Imitation practice over five sessions did not clearly reduce movement variability, but retrieval practice reduced it for some children with speech sound disorder.
• SLPOther2017The Relationship Between Baseline Volume in Temporal Areas and Post-Treatment Naming Accuracy in Primary Progressive Aphasia.AphasiologyPre-treatment temporal lobe volume was not linked to naming accuracy after anomia treatment for trained words. Both phonological and orthographic treatment produced better naming for practiced words than unpracticed words, but this study does not support using scan volume alone to guide treatment choice.
• SLPCohort2017Some Neurocognitive Correlates of Noise-Vocoded Speech Perception in Children With Normal Hearing: A Replication and Extension of ).Ear and hearingChildren with normal hearing who have better auditory attention and verbal short-term memory recognize spectrally degraded speech more accurately. This suggests that cognitive skills, not just hearing, drive speech perception when the signal is poor.
• SLPOther2017Phonemic awareness of English second language learners.The South African journal of communication disorders = Die Suid-Afrikaanse tydskrif vir KommunikasieafwykingsSetswana-speaking Grade 3 learners given a combined vowel, segmentation and literacy programme improved word discrimination and segmentation, but the no-training control group also improved, and blending did not change.
• SLPOther2017Infants' and Adults' Use of Temporal Cues in Consonant Discrimination.Ear and hearingThree-month-olds could discriminate consonant categories using only slow temporal cues, but only 13 of 26 did in quiet. Adults did so in quiet, and fewer adults passed in noise.
• SLPNarrative Review2017Short-Term Memory and Aphasia: From Theory to Treatment.Seminars in speech and languageVerbal short-term memory is commonly impaired in aphasia and may help characterize semantic versus phonological deficits. Treatment evidence is from case studies, so larger studies are needed.
• SLPCase-Control2017Auditory spatial attention to speech and complex non-speech sounds in children with autism spectrum disorder.Autism research : official journal of the International Society for Autism ResearchWhen listening to sounds straight ahead, children with autism responded more to nearby non-target sounds than controls, even when detecting the target sound was similar. The study did not show a speech-specific difficulty.
• SLPOther2017Effect of Energy Equalization on the Intelligibility of Speech in Fluctuating Background Interference for Listeners With Hearing Impairment.Trends in hearingFor listeners with hearing loss, a signal-processing method increased the benefit from regular fluctuating noise, but not from speech-like noise, and average consonant scores were lower than with unprocessed speech.
• SLPOther2017Spatiotemporal movement variability in ALS: Speaking rate effects on tongue, lower lip, and jaw motor control.Journal of communication disordersTalkers with mild to moderate ALS had less variable tongue dorsum and lower lip movements during typical speech than controls. Slow speech increased variability in ALS; fast speech did not. These are group differences, not treatment effects.
• SLPNarrative Review2017Tutorial: Speech Assessment for Multilingual Children Who Do Not Speak the Same Language(s) as the Speech-Language Pathologist.American journal of speech-language pathologyThis is an expert tutorial, not a study. It gives guidance on assessing multilingual children's speech, but it reports no tested outcomes.
• SLPOther2017The Influence of Noise Reduction on Speech Intelligibility, Response Times to Speech, and Perceived Listening Effort in Normal-Hearing Listeners.Trends in hearingNoise reduction did not speed simple digit identification in 12 normal-hearing listeners. It did speed a harder arithmetic task. The ideal algorithm felt less effortful; the realistic algorithm did not change perceived effort.
• SLPOther2017Perceptual statistical learning over one week in child speech production.Journal of communication disordersHearing a sound sequence in more words and from more talkers did not improve overall speech accuracy across a week. A small advantage appeared in the first production, then faded. This does not show that hearing more talkers and words alone fixes child speech errors.
• SLPCase Report2017Effects of semantic context on access to words of low imageability in deep-phonological dysphasia: a treatment case study.AphasiologyThe cohesive phrase condition helped a person with aphasia repeat treated abstract word pairs, reaching the accuracy target after 10 probes. The non-cohesive phrase condition did not help. This was a single case.
• SLPCase-Control2017Slowed articulation rate is a sensitive diagnostic marker for identifying non-fluent primary progressive aphasia.AphasiologyThe rate measures did not clearly beat clinician fluency ratings in the main accuracy comparison, but slow articulation rate was the best marker and helped identify non-fluent PPA when false alarms were low.
• SLPOther2017The Benefit of a Visually Guided Beamformer in a Dynamic Speech Task.Trends in hearingWhen talkers moved, the eye-steered beamformer was worse than the natural listening condition and the hybrid was no better. With a fixed talker, the hybrid helped, and the beamformer helped mainly straight ahead.
• SLPOther2017The Benefits of Bimodal Aiding on Extended Dimensions of Speech Perception: Intelligibility, Listening Effort, and Sound Quality.Trends in hearingAdding a hearing aid to a cochlear implant improved speech understanding in quiet and noise, reduced listening effort at the most favorable tested level, and made sound fuller and less tinny in 15 adult bimodal users.
• SLPCohort2017Predictors of Hearing-Aid Outcomes.Trends in hearingCochlear hair-cell loss was not linked to hearing-aid outcomes. Better detection of frequency changes and younger age were associated with better speech-in-noise with hearing aids; unaided quiet speech scores were the best simple clinical guide.
• SLPCase Series2017Rapid recovery from aphasia after infarction of Wernicke's area.AphasiologyTwo people with aphasia after Wernicke's area strokes gained language ability quickly at first, then more slowly over 3 months. Speech rate and complexity rose, errors fell. By 3 months they still had conduction aphasia deficits.
• SLPCohort2017Connected speech in transient aphasias after left hemisphere resective surgery.AphasiologyWithin 2-3 days after left hemisphere resection, all 10 connected speech measures worsened in the 29 patients with aphasia; by 1 month most improved, but phonological errors and lexical access remained above pre-surgery levels.
• SLPRCT2017Evaluation of a Frequency-Lowering Algorithm for Adults With High-Frequency Hearing Loss.Trends in hearingIn 10 adults with high-frequency hearing loss, a frequency-lowering hearing aid setting did not improve overall consonant identification, speech in noise, or everyday hearing ratings. It did improve detection of word-final s and z sounds.
• SLPOther2018Prophylaxis and remediation of anomia in the semantic and logopenic variants of primary progressive aphasia.Neuropsychological rehabilitationNaming practice using spoken repetition or written copying helped people with semantic or logopenic progressive aphasia keep or improve names for practiced words compared with untrained words. Results were strongest in semantic variant; logopenic variant effects were mixed.
• SLPCase Series2018The nature and treatment of phonological text agraphia.Neuropsychological rehabilitationFour people with writing difficulty after stroke wrote more grammatically after phonological treatment, spelling treatment, homework, spell-checker, and, for one, reading treatment. Well-formed written sentences rose from 35% to 73.1%, but this was a small case series.
