Speech and language differences

The terms speech, language, and communication are often used interchangeably, but they have distinct meanings. Language refers to the comprehension and use of words and sentences to convey meaning, and can be written, spoken, or signed. Speech refers to the production of vocal sounds and involves both motor and linguistic skills. It is possible to have impaired speech but intact language.

Communication encompasses both language and speech, and includes both verbal and nonverbal means of expression. Difficulties with speech, language, and communication may be due to neurological differences, or the result of an accident or pre-existing medical condition such as sensorineural hearing loss. 

Language learning difficulties and language impairments are very common, and can have a significant impact on students’ ability to succeed at school and beyond. Students who experience difficulty understanding and/or expressing themselves through language may struggle with understanding words, following instructions, answering questions, remembering what someone has said, and paying attention. They are highly likely to struggle with learning to read and write. One of the most common forms of language-based learning difference is Developmental Language Disorder, a neuro-developmental condition, and it is estimated that up to 14% of people may have DLD.

The complex nature of language means that the identification and definition of language-based learning difficulties has not been straightforward, and there has been a lack of agreement on how to identify and classify these differences. However, there is a growing body of evidence on how to effectively support students with a range of speech and language difficulties.

It is important for teachers and schools to be attentive to difficulties students may be experiencing in understanding and expressing themselves verbally and non-verbally through language. Often language-based difficulties may be mis-identified as poor behaviour or a lack of attention. Many students may require specific support, and it is important for teachers to work with specialists such as speech language therapists. There are also many ways that teachers can support these students as part of their regular practice, such as effectively teaching new vocabulary, using multi-modal ways of presenting information and instructions, and attending to students’ cognitive load demands.
