According to American Speech- Language-Hearing Association (ASHA), speech is the verbal means of communicating. It consists of the following:
Articulation – how speech sounds are made (e.g., children must learn how to produce the “r” sound in order to say “rabbit” instead of “wabbit”).
Voice – use of the vocal folds and breathing to produce sound (e.g., the voice can be abused from overuse or misuse and can lead to hoarseness or loss of voice).
Fluency – the rhythm of speech (e.g., hesitations or stuttering can affect fluency).
Children acquire new sounds as they grow. A child as young as 3 months, is able to cry differently to communicate his needs. By 6 months, he is starting to babble speech – like with many different sounds including p, b, and m. By 9 months, his babbling has both long and short groups of sounds such as “tata upup bibibibi”. And as he hears new sounds, he starts to combine them forming meaningful words to communicate.
Through the course of child development, it is important as parents to understand the typical development of speech sounds. However, there are several speech sound developmental milestones out there and they vary from one culture to another. This implies that there is no telling whether your child should have acquired or mastered a specific set of sounds at a certain age. So, to expect a child to use a certain sound 100% of the time at a particular age is too much of a goal. There is a wide range of “typical speech sound development”, which can also be affected by culture and bilingualism.
Having said that, it is still important to use these set of norms as a guide to understand your child’s speech development and to decide whether he needs help from a speech therapist.
The most commonly used speech norms is from Goldman Fristoe Test of Articulation 2, GFTA-2, (2000).
As mentioned earlier, the norms above serves as a guide to tell whether your child’s speech is developing accordingly. Most children makes mistakes when they are learning new sounds or words. Children simplify adult speech as they learn to talk. This is called phonological processes. This is normal. However, if mistakes persist beyond the expected age of acquisition and that speech intelligibility is greatly compromise, it is worth noting to seek consult from a speech therapist.
Other notable red flags for your child’s speech sound development are as follows:
Again, these are only guidelines. These serve as additional information for you to decide whether your child needs speech therapy to help correct his speech errors. Always remember that all children undergo through a stage whereby speech errors are more prominent. However, these errors start to disappear as he grows older. It is always good to seek professional consult with a speech therapist should you suspect your child may have speech errors.
