Speech therapy is a field of healthcare that focuses on diagnosing and treating communication disorders and difficulties with speech, language, and swallowing. It involves working with individuals of all ages who have challenges with articulation, fluency, voice, language comprehension and expression, cognitive communication, and swallowing difficulties. Speech therapists, also known as speech-language pathologists, use various techniques such as exercises, games, and technology to help improve communication skills and overall quality of life for their clients. Research in speech therapy aims to better understand the underlying causes of communication disorders and develop effective interventions and treatments to improve communication abilities and overall quality of life for individuals with these disorders.
