Speech therapy is an intervention service that focuses on improving a child's speech and ability to understand and express language, including nonverbal language. Speech therapists, or speech and language pathologists (SLPs), are the professionals who provide these services. Speech therapy includes two components: 1) coordinating the mouth to produce sounds to form words and sentences (to address articulation, fluency, and voice volume regulation); and 2) understanding and expressing language (to address the use of language through written, pictorial, body, and sign forms, and the use of language through alternative communication systems such as social media, computers, and iPads). In addition, the role of SLPs in treating swallowing disorders has broadened to include all aspects of feeding.
