Language and Communication Science

Centre for Language and Communication Science Research

The Centre for Language and Communication Science Research carries out research into all aspects of speech, language and communication disorders, as well as typical speech and language.

Our Research

Adult Assessment and Intervention Research (AAIR)

This group investigates the nature and treatment of adult acquired communication disorders, with a particular emphasis on aphasia.

Aphasia Research

Themes in aphasia include: the investigation of aphasic language impairments, the impact of therapy, interventions to improve emotional and social wellbeing in people with aphasia, and assessment, outcome measurement and the self- reported experience of aphasia. In this last area, tools developed at City, e.g. the SAQOL-39g, have become an international gold standard and are recommended for use in all aphasia trials and intervention studies (see Core Outcome Set for Aphasia).

Current studies are exploring the use of technology in aphasia therapy and the impact of therapies on activities, participation and quality of life. We are exploring the benefits of a virtual communication environment, EVA Park, for people with aphasia, and are evaluating therapies that make use of mainstream technologies, such as text to speech software (for example CommuniCATE and READ-IT.)

We are evaluating interventions aimed at improving wellbeing in people with aphasia, such as peer-befriending (SUPERB) and Solution Focused Brief Therapy. Further work is developing a novel intervention for narrative discourse (LUNA). Many of AAIR’s aphasia projects are conducted in collaboration with City’s Centre for Human Computer Interaction Design. A current project with this Centre is developing tools that enable people with aphasia to create and curate digital content.

Special Interest Groups

A Special Interest Group of AAIR focuses on head and neck cancer research.  Our work in this area has explored, among other things, the development and evaluation of outcome measures for this population and quality of life and swallowing outcomes after laryngectomy.

Past and present collaborators include the Royal College of Speech and Language Therapists’ Head & Neck Clinical Excellence Network, the University College London Hospital and Barts Health NHS Trusts. Another Special Interest Group focuses on dysphagia research across the lifespan (see also DAIR).  With adults, the dysphagia group have a particular focus on Parkinson’s disease, and adults with learning disabilities.


The group has attracted research funding from national and international bodies including:  the Barts Charity, the Bupa Foundation, the Dunhill Medical Trust, the EPSRC, the EU, the NIHR, the Stroke Association, and the Tavistock Trust for Aphasia.

Developmental Assessment and Intervention Research (DAIR)

This group explores the identification, impact and treatment of developmental language disorders (DLD), for example Engage with DLD project, and the communication and related cognitive difficulties associated with other childhood developmental disorders (e.g. autism, intellectual disabilities). Early years studies have developed assessment and diagnostic tools and have used these to investigate how very early processing skills may affect language and social communication in school-age children (VEPS).

Further themes of this group include the relationship between language and social wellbeing in children and young people, new interventions to improve vocabulary and language skills, dynamic assessments of language skills, predictors of language and literacy skills in adolescents with intellectual disabilities (for example Memory and Language in Children) and the role of registered intermediaries in assisting child witnesses with and without autism to give their best evidence (Access to justice).

Early years assessments developed by this group are appropriate for children from diverse backgrounds and are being used by paediatric NHS services (e.g. Lambeth and Southwark) and special early years provisions. Research from the group has generated novel insights into the long term consequences of developmental language disorders, e.g., by exploring impacts in adolescence and young adulthood.

Promising new interventions to support language learning and vocabulary development in primary and secondary age children and young people have been developed and evaluated. Criminal justice professionals have benefited from understanding how registered intermediaries assist young children to give fuller accounts of witnessed events.

Special Interest Groups

A Special Interest Group of DAIR focuses on dysphagia research. The group investigates dysphagia across the lifespan and the rationale underpinning dysphagia interventions.

Projects have included funded research into neonatal feeding, paediatric gastrostomy tube feeding, parents’ perceptions of instrumental swallow assessments, supporting the eating and drinking of children with learning disabilities through use of mealtime mats and education staff training, and typical development of swallowing skills.

These projects have been undertaken with a range of NHS Trusts (including the Royal Free NHS Trust and Imperial College Healthcare NHS Trust), and international speech and language therapy teams.


The DAIR group has attracted research funding from national and international bodies including: the Baily Thomas Charitable Trust, the Communication Trust, the Department for Education, the Department for International Development, the ESRC, the EU, the Heather Van der Lely Foundation, the Nuffield Foundation, the NIHR, the Redbridge, and Barking and Dagenham local authorities, the Swedish Research Council and the Waterloo Foundation.

Speech, Phonology and Linguistics

The research of this group generally focuses on the production and perception of typical and atypical speech and language.

From a phonetic perspective, this research group has carried out experimental studies on a wide range of topics such as the devoicing of English fricatives, the acoustic characteristics of vowels in typically developing children and children with hearing impairment, the analysis of asymmetries in tongue-palate contact in speech and the analysis of articulation errors in speakers with motor speech disorders (Speech Sound Disorders, Dysarthria, Foreign Accent Syndrome).

Additionally, the group has world-class expertise in Forensic Phonetics and is actively involved in the analysis of speech for legal purposes. Furthermore, the group has made a strong research contribution to the pedagogical aspects of phonetics teaching and the application of phonetic transcription in Speech and Language Therapy. Finally, the group has produced a series of in-depth phonetic descriptions of various languages (Standard Dutch, Hamont Dutch, Lusoga, Punjabi and Zulu) which have been published in the Journal of the International Phonetic Association as illustrations of the IPA.

From a linguistic perspective, a major research strand has been the use of linguistic analysis in clinical settings and the development of discourse treatment programmes for people with aphasia (LUNA) and for older adults living in residential settings (STARs). Another significant research strand has focused on language, identity and inclusion within professional contexts – a focus that has included analysis of gendered discourses in Speech and Language Therapy and the role they may play in maintaining a lack of diversity in this professional context. Finally, several publications have focused on the key principles and contributions of core research methodologies in linguistic research.

In an audiological perspective, several studies have been carried out on noise exposure levels from personal stereo players, the effects of background noise on speech perception and the assessment of deaf awareness among heathcare students.

Phonetics and Audiology Lab

This group is supported by a well-equipped phonetics and audiology lab. The phonetics lab has state-of-the-art instrumentation to analyse various aspects of speech production such as oral/nasal airflow and pressure (Pcquirer, Nasometer), vocal fold vibration (laryngography), tongue-palate contact in speech (Electropalatography), tongue configuration in articulation (Ultrasound).

In addition the lab has a wide range of software packages to analyse the acoustic characteristics of speech. Audiological equipment consists of screening and clinical audiometers, tympanometers, an oto-acoustic emissions and auditory brainstem response screener and a range of hearing aids for mild-moderate and severe-profound hearing loss and several sound level meters (among others B&K type 2250). In addition there is a range of software applications to analyse aspects of hearing.


This group has attracted research funding from national and international bodies including: the Dunhill Medical Trust; the Flemish Science Foundation; the Leverhulme Trust; the Royal Flemish Society of Belgium for Sciences and the Arts; and the Stroke Association.

Deafness and Visual Language Research

This group has pioneered research into the effects of deafness on all aspects of child development including language, cognitive development and literacy. The group has explored sign language development in deaf children and created the first standardised clinical assessments of language development in British Sign Language (BSL) which have since been adapted into 18 other sign languages internationally.

Other themes include theory of mind in deaf children, speechreading in deaf and hearing individuals, reading and dyslexia in deaf children, language impairments in signers, spoken language acquisition, language and reading interventions and music training to enhance executive function. The group has a further interest in the impact of acquired language and cognitive impairments on sign language and published the first investigations of aphasia in users of BSL.

The group links with the Deafness, Cognition and Language Research Centre (DCAL) at UCL.


The group has attracted research funding from: the Alzheimer's Society; the ESRC; the Heather van der Lely Foundation; the Leverhulme Trust; and the Nuffield Foundation.
