All children develop speech and language skills at their own rate. Although each child is unique in their development, researchers and scholars in the field of speech-language pathology have developed speech and language developmental milestones to help measure children’s development. Average ages for achieving these milestones have been determined to monitor developmental progress. To better understand speech and language developmental milestones it is important to understand the difference between speech and language skills. This article will explain the difference between speech and language and provide a time line for typical speech and language developmental milestones from birth to 8-years of age.
What is the difference between speech and language?
It is important to think of speech and language as two separate entities. In the simplest terms: think of language as all of the thoughts and ideas in your head represented as words and speech as the physical act of producing those words using your mouth.
More technical definitions:
1. Language is a socially shared system of representing ideas through the use of arbitrary symbols and rule-governed combinations of those symbols for the purpose of communication. Symbol types include spoken words, sign language, pictures, etc. Language is broken into three areas: receptive and expressive language and pragmatics. Receptive language is the ability to comprehend what others are saying (e.g., ability to follow directions) while expressive language is the ability to use language to express oneself. Pragmatics is the social use of language (e.g., appropriately greeting others, use of eye contact or protesting appropriately).
2. Speech is the verbal means of communicating or conveying meaning. Speech production involves four processes: respiration (coordinating breathing patterns with speech), phonation (voice), resonation (vibration of sounds within the nose, mouth and throat) and articulation (producing speech sounds through the intricate movements of the tongue, lips, teeth, jaw and roof of the mouth). Speech production requires precise coordination and intricate movements of our oral musculature otherwise known as articulation.
Now that you understand the difference between speech and language I will outline some typical speech, language and hearing developmental milestones. Below is a time line of “typical” speech, language and hearing development. The ages listed on the time line have been complied from several respected, published texts and websites (“Language Development” by Robert Owens, “Articulation and Phonological Disorders” by Bernthal and Bankson, asha.org, and firstwords.fsu.edu).
It is important to note that all children develop at their own rate. Ages and corresponding skills will vary slightly from what is listed on this chart for most typically developing children. If your child is not demonstrating one or more skills in a given age category this does not necessarily indicate a delay or disorder. However, if your child does not demonstrate the majority of skills listed within his or her age category seek the advice of an ASHA certified speech-language pathologist.
