Communication, Speech, Language: A Story About the Differences and Disabilities of the Three
Min Jung KwonShare
If you have been receiving treatment or are looking for information about your child's language development, you will likely hear the words 'communication', 'speech', and 'language' often.
These three terms are often used interchangeably or interchangeably, but if your child has a language delay or difficulty speaking, understanding these terms clearly is the first step in providing them with appropriate help.
In this post, we'll explore what communication, speech, and language are, the differences between them, and what impairments in each concept mean.
1. What is communication?

Communication refers to the entire process of conveying and understanding thoughts, feelings, and information. Communication can occur through various means, including speech, language, facial expressions, and gestures . Even without verbal expression, a great deal of information can be exchanged through facial expressions and gestures.
Example : A child pointing to an object they want with their hand or expressing their feelings by smiling are also forms of communication.
2. What is speech?

Speaking is the process of forming words and sentences by making sounds. We communicate by pronouncing words and controlling the tone and pace of our voices . If our pronunciation is unclear, or if our voice is too soft or rough, verbal communication can become difficult.
Example : When a child calls "Mom," this pronunciation and use of voice is part of speech.
3. What is Language?

Language is a systematic way to express thoughts and feelings. It can be expressed not only through speech, but also through writing, body language, and other means . Language enables communication using words and sentences, and encompasses not just the pronunciation of words but also the meaning and rules embedded within them.
Example : When a child says, "I'm hungry," he or she is using language to express his or her thoughts.
4. Differences between communication, speech, and language
Let's clarify the differences between communication, speech, and language.
Communication : The entire process of conveying and understanding information. This occurs through various means, including speech, language, and gestures.
- Speech : This is the part of communication that is done through sounds and pronunciation.
- Language : A system for creating meaningful sentences through sounds, writing, or body language.
While these concepts are naturally interconnected, problems can arise in one or more areas. Next, let's examine what communication disorders, speech disorders, and language disorders each mean.
What are communication disorders, speech disorders, and language disorders?
Children may experience difficulties with one or more of the following: communication, speech, or language. In these cases, a disability may exist, each with slightly different characteristics.
1. Communication Disorders

A communication disorder refers to a child's difficulty expressing or understanding thoughts or feelings. Problems can occur in any communication process, including speech, language, and nonverbal cues .
Communication disorders are a very broad concept, encompassing speech disorders, language disorders, social communication disorders, and difficulties with nonverbal communication.
Example : A child has difficulty understanding what others are saying or expressing his or her own thoughts.
2. Speech Disorders

A speech disorder is a difficulty pronouncing words accurately or using the voice. This may be due to inaccurate pronunciation, voices that are too soft or too loud, or speech with an unusual rhythm .
Example : If your child has trouble pronouncing certain words correctly, or stutters or pauses when speaking.
3. Language Disorders

A language disorder refers to a child's difficulty understanding or expressing language. A child may have a language disorder if they are unable to form sentences or acquire an age-appropriate vocabulary.
That is, they have difficulty learning and using the rules and systems of language, such as sentence structure, word choice, and grammar use.
Example : If a child does not understand a sentence or cannot express in words what he or she wants.
Although communication disorders and language disorders may seem similar, communication disorders include all problems in verbal and nonverbal communication, whereas language disorders can be seen as problems limited to the ability to use language.
