What Is Speech and Language Therapy, and Who Can It Help?

Speech and language therapy supports people with communication, speech, eating, drinking and swallowing needs. According to the Royal College of Speech and Language Therapists (RCSLT), speech and language therapists (SLTs) work with both the people who have these needs and the people who care about them. If you or someone close to you struggles to communicate, speak, eat, drink or swallow, an SLT is the professional trained to help.

What speech and language therapy covers

RCSLT describes the field as supporting people with communication and swallowing needs. In practice, that spans several connected areas:

• Communication – understanding and expressing language, and using it in everyday situations.
• Speech – producing sounds and words clearly.
• Eating and drinking – managing food and drink safely and comfortably.
• Swallowing – the physical process of swallowing, which can be affected by a range of conditions.

Because these needs can arise at any age and from many causes, speech and language therapy is not limited to one group or setting.

Who it can help

The RCSLT frames its work around "people with communication and swallowing needs" and the people who care about them. That means the people who benefit include:

• The person with the need – someone finding it hard to communicate, be understood, or eat, drink and swallow safely.
• Carers, family and friends – the people supporting them day to day, who also need to understand the difficulty and how to help.

If you are unsure whether a difficulty is something an SLT would address, the RCSLT's public information on what speech and language therapy is is the place to check how therapists support people with communication, speech, eating, drinking and swallowing.

What speech and language therapists do

RCSLT is the professional body for SLTs in the UK. It describes its role as supporting therapists by providing leadership and guidance, facilitating research, and promoting better education and training. That professional backing matters to the public because it means the therapists you encounter are part of a regulated, guided profession.

To see the role in practice, RCSLT offers SLT Voices, a collection of blogs, articles and case studies that highlight the perspectives of speech and language therapists and the breadth of their expertise. These first-hand accounts are a useful way to understand what therapists actually do, beyond a definition.

How to learn more

If you want to go further than this overview, RCSLT provides:

• A video introduction to speech and language therapy, explaining the ways SLTs support people.
• SLT Voices – blogs, articles and case studies from therapists themselves.
• Events and webinars – sessions on professional topics, such as the CPD Portfolio webinar listed for 5 November 2026.

These resources are aimed at explaining the profession and its reach, so they suit anyone deciding whether to seek support, or simply wanting to understand what speech and language therapy is.

The short answer

Speech and language therapy helps people with communication, speech, eating, drinking and swallowing needs – and the people who care for them. Speech and language therapists are the professionals who provide that support, and in the UK their professional body is RCSLT.
