Speech vs. Language vs. Communication: What is the Difference? 

  • Speech: Refers to the sounds that come out of your mouth that are combined to form words. Speech includes: 
  • Articulation: The physical act of producing speech sounds using the mouth, lips, and tongue. Problems with articulation include difficulty producing certain sounds. For example, a common speech sound difficulty includes pronouncing “s” (commonly known as a lisp). An articulation disorder can result in a child being very difficult to understand.  
  • Voice: How we use our vocal folds to breathe and make sounds. Voice can vary in quality (e.g., hoarseness), loudness, pitch, etc.  
  • Fluency: Fluency is the rhythm of our speech. Fluency can be affected by many things, including word-finding, sentence formulation, and rate of speech. Typical and atypical dysfluencies (i.e., stuttering) are included in this category. 
  • Language: Language is a rule-based system used to communicate. Language is the process of combining words to formulate a message in a grammatical way and our ability to understand itLanguage can be verbal (using words, sentences, etc.) or non-verbal (sign language). There are 3 main categories of language: 
  • Receptive language: The ability to understand language.  
  • Expressive language: The ability to produce and use language to communicate with others. 
  • Pragmatic language: The ability to use language in specific situations and having an understanding of social rules.  
  • This includes using language for different reasons (e.g., greetings vs. requesting vs. informing, etc.), the ability to change language depending on the context (e.g., speaking differently to a peer vs. an adult), and following social rules of communication (e.g., turn-taking, staying on topic, using gestures, facial expressions, eye contact, etc.). 
  • Communication: An umbrella term that includes speech and language. Communication involves any form of expression in order to convey or understand a message. 
  • Basically, any way you can communicate and get your message across.  
  • Modes of communication include words, gestures, objects, sounds, signs, pictures, symbols, printed words, and output from augmentative and alternative (AAC) devices. 


  • Speech: the ability to pronounce words using sounds 
  • Language: the rule-governed that allows us to understand what others are saying to us and the ability to use words to produce a message to others.   
  • Communication: everything combined! Anything you can do to convey and understand a message whether it be through spoken language, gestures, pictures, sounds, etc.
