Speech and Language Therapists (SLTs), also called Speech-Language Pathologists (SLPs), are allied health professionals who assess and treat a wide range of communication and swallowing disorders. These include speech sound disorders (articulation, phonology), language disorders (understanding and expression), fluency disorders (stuttering), voice disorders, and dysphagia (swallowing difficulties). SLTs work with children who have delayed language development, autism spectrum disorder, or cleft palate; adults who have had strokes, brain injuries, or degenerative neurological conditions (Parkinson's, ALS); and people with intellectual disabilities. In Sri Lanka, Speech and Language Therapy is offered through the University of Kelaniya and is practised in government hospitals, special schools, and a growing private sector. Internationally, SLT / SLP is one of the fastest-growing allied health professions, with acute shortages in the UK, Australia, Canada, and the USA.

What a Speech and Language Therapist does daily

  • Assess speech, language, communication, and swallowing disorders across all age groups
  • Design and deliver individual and group therapy programmes to improve communication
  • Treat children with delayed language development, articulation disorders, and stammering
  • Work with children and adults with autism to develop functional communication — verbal and AAC
  • Provide dysphagia (swallowing) assessment and management — a critical hospital-based skill
  • Support stroke and brain injury survivors to regain spoken language and communication
  • Work with people who have Parkinson's disease, ALS, or other degenerative conditions affecting speech
  • Prescribe and train in Augmentative and Alternative Communication (AAC) devices and systems
  • Collaborate with occupational therapists, physiotherapists, doctors, and educators in multidisciplinary teams
Why this matters: Communication is the most fundamentally human capacity. A child who cannot speak or be understood is excluded from education, friendships, and full development. A stroke survivor who cannot communicate loses independence, identity, and connection. A person with autism who has no functional communication lives in profound isolation. Speech and Language Therapists restore the ability to connect, learn, and participate in society — arguably the most impactful intervention in all of allied health.

  • Volunteer at a special needs school or disability organisation to understand communication disorders first-hand
  • Build Biology and Science foundations — anatomy and neuroscience underpin SLT
  • Consider the breadth of SLT work — children with autism and stuttering, adults after stroke, elderly with Parkinson's

Important notes
