Speech and language therapist

Roles, settings and populations

Therapists work with infants, children, adults and older people in many settings: nurseries and schools, community clinics, hospitals, rehabilitation centres, care homes and private practice. Their work often involves collaborating with families, teachers, doctors, nurses, occupational therapists and psychologists to plan and deliver care that supports communication, education and safe eating.

Common conditions

• Developmental language delay and disorder
• Speech sound disorders and articulation problems
• Fluency disorders such as stuttering
• Aphasia and language disorders after stroke or brain injury
• Motor speech disorders (dysarthria, apraxia of speech)
• Voice disorders and vocal fatigue
• Dysphagia (swallowing difficulty)
• Social communication difficulties and pragmatic language impairment

Assessment and therapy approaches

Assessment typically combines case history, observation, standardized tests and functional measures of participation. Therapy is individualised and evidence-based, and may include exercises to strengthen muscles, strategies to improve clarity and fluency, language stimulation techniques, training in alternative and augmentative communication (AAC) and environmental or educational modifications. Therapists also provide caregiver training and advice about safe feeding and diet consistency when swallowing is affected.

Training, history and professional context

The profession emerged as a distinct clinical discipline in the late 19th and early 20th centuries and now requires formal education and supervised clinical placements. Practitioners are usually regulated or certified by national bodies, and continuing professional development is common. Practice increasingly incorporates technology, telepractice and evidence-based protocols.

Importance and distinctions

Speech and language therapists improve communication, participation and quality of life and reduce health risks associated with dysphagia. They differ from audiologists (who focus on hearing) and from language teachers (who teach language skills rather than treat disorders). Working as part of a multidisciplinary team, therapists focus on functional goals that matter to the person and their everyday life.
