S Words

Difficulty articulating the /s/ sound is a common speech disorder and it is often referred to by some speech and language pathologists as a lisp. Let’s have a look at different types of lisps, speech therapy strategies, and exercises focusing on the/s/ sound and /s/ words.

Children who have a frontal lisp, (also known as an interdental lisp) produce the /s/ sound with the tongue protruding forward between the front teeth, similar to the /th/ sound when trying to pronounce /s/ words.

Some children may demonstrate other types of lisps when attempting to make an /s/ sound. For example, a lateral lisp when trying to pronounce /s/ words.

A lateral lisp is characterized by a “slushy” sounding attempt at the /s/ sound, in which air escapes out of the sides of the mouth.

Developmental norms state that children are typically able to produce the /s/ sound and say /s/ words by age 4.

Aside from lisps, children may demonstrate several other types of errors when attempting to produce the /s/ sound. For example, the phonological process of stopping. In this phonological process, the /s/ sound is replaced by a stop sound, such as a /t/ (as in “tee” for “see”). According to the American Speech-Language-Hearing Association (ASHA), the phonological process of stopping when attempting /s/ words should be resolved by age 3.

Other children may omit the /s/ sound within consonant blends, a process known as consonant cluster reduction. A child using this process may say “top” instead of “stop”. This phonological process is typically eliminated by age 5.

Many speech therapists may find themselves continuously repeating to the child, “keep your tongue back” when working on the /s/ sound with a child who has a lisp. But what happens when that’s not enough to help the child correctly produce this sound to pronounce /s/ words?

Swords can certainly be among the most challenging words for children to correctly pronounce. Having difficulty articulating the /s/ sound when pronouncing /s/ words can affect children socially, educationally, and when effectively communicating with others.

Kids need to be able to pronounce /s/ words like sleepy, swing, and store.

So, here is a list of the best speech exercises and activities to keep in your SLP toolbox for teaching the /s/ sound, as well as a word list organized in order of complexity.

Exercise #1: The Long /t/ Method

One of the clearest ways to teach the /s/ sound is by using the long /t/ method.

As outlined by the well-known SLP Pam Marshalla, this method includes first asking the child to produce the /t/ sound.

• After you’ve ensured the child can correctly produce the /t/ sound, instruct him or her to “stretch out” or “blow longer” by exhaling a gentle stream of air at the end of the sound.
• Demonstrate how to do this by making an over-exaggerated /t/ sound.
• Next, ask the client to make this long /t/ sound again while lifting their tongue tip up to the “bumpy spot behind the top teeth” (the alveolar ridge).

The result should be a great /s/ sound.

This can be an effective method for eliciting an /s/ sound in a child with a lisp. Continue working on the /s/ sound in isolation with your client. Once he or she has mastered this, move on to the next level by working on /s/ in syllables.

Exercise #2: Find the Front

Children who have a lateral lisp produce the /s/ sound with air coming out of the sides of their mouth.

One of the best ways to correct this is by teaching the client to direct the air stream through the front of their mouth.

• Show the child how you put one finger in front of your mouth at the center. As you make the /s/ sound, talk to your client about how you can feel a stream of “air“ in the middle, on your finger.
• Next, it’s the child’s turn. Ask him or her to put their finger in front of their mouth and try making the air flow in the same direction you did.

Exercise #3: The Butterfly Position

This technique teaches the child a clear way to visualize how to position the tongue to make the /s/ sound.

Can your client make the /i/ sound (as in “in” and “tin”)? If so, ask him or her to make this sound. Talk about how when they make the /i/ sound, the sides of their tongue are slightly raised up (and touching the teeth) which create the shape of butterfly wings.

The tongue should also have a central groove, similar to the shape of a butterfly’s body. After producing the /i/ sound, ask the child to keep their tongue in this position and produce the /s/ sound.

Remind him or her that the air should flow over that central groove, out of the middle of the mouth, and remember to keep it fun.
