    How we assess speech sound difficulties

    If your child is hard to understand, mixes up sounds, or says ‘tat’ instead of ‘cat’, you might be wondering what actually happens at a speech sound assessment. It is a really common question, so I want to walk you through what I do in clinic.

    Speech sound difficulties look different in every child. Two children can both struggle with the /K/ sound for completely different reasons. The assessment is how I find out the why, so that therapy targets the right thing from the start. For your child, it mostly feels like playing games and looking at pictures.

    Step 1: Listening to sounds

    I usually begin with sound awareness. This is your child’s ability to hear, notice and play with the sounds in words.

    We might do some rhyming (‘Does cat rhyme with hat?’) or clap out the beats in words, like ba-na-na or el-e-phant. Children usually enjoy this part, and it helps them settle in.

    Why start here? Being able to hear and think about sounds is the foundation for saying them clearly. It also supports reading and spelling later on. If a child finds it hard to hear the difference between sounds, that tells me a lot about where their speech difficulties may be coming from.

    Step 2: How the mouth moves

    Next, I look at oro-motor skills. That simply means how the lips, tongue and jaw look and move.

    I might ask your child to copy some movements: a big smile, a kiss, poking their tongue out, or moving it from side to side. I also watch how they manage these movements one after another. I often use my puppet and show how its tongue can move. Before I go and look into a child’s mouth I demonstrate on my puppet how we do this.

    This helps me check whether the muscles and movements needed for speech are working as they should. It is one piece of the puzzle, not the whole answer, but it helps me rule things in or out.

    Step 3: Vowels

    Vowels are the ‘open’ sounds in words, like the sounds in cat, bed, sheep, moon and boat. They are easy to overlook, but they make a huge difference to how clear speech sounds.

    I use vowel picture sheets and vowel pictures, and I listen carefully as your child names them. Most children get their vowels right quite early. If vowels are tricky, it can point towards particular types of speech difficulty, so this step really matters.

    Step 4: Choosing the right next assessment

    By this point I have a good idea of what might be going on. I then choose the assessment that fits your child best.

    The CLEAR Phonology Screen (or an informal phonology screen).

    Your child names a set of pictures, and I write down exactly how they say each word. This shows me which sounds they can say, which ones they swap, and any patterns. For example, some children leave off the ends of words (‘ca’ for ‘cat’). Others replace all back sounds with front sounds (‘tar’ for ‘car’). It also picks up difficulties with single sounds, such as a lisp on /S/.

    The Nuffield Dyspraxia Programme assessment.

    If I think your child might have difficulty planning and sequencing the movements for speech, I use this instead or as well as. This can be the case with childhood apraxia of speech, sometimes called verbal dyspraxia. Your child names pictures and copies words that gradually get longer. I am looking at how well they can link sounds and syllables together smoothly, and how consistent their speech is.

    I do not use every test with every child. Choosing the right one means the assessment is focused, and it does not tire your child out.

    What happens afterwards

    Once the assessment is done, I look closely at everything I have noted. I then talk you through what I found, in plain language. Together we agree clear goals for therapy and the order in which to work on them.

    You will also get ideas for simple games and activities to do at home. Short, regular practice at home makes a real difference to progress.

    A few things parents often ask

    Does my child need to prepare? No. Just come as you are. I adapt everything to your child’s age and mood on the day.

    What if my child is shy or will not join in? That is completely normal. I take things at your child’s pace, and we can always finish another time.

    Can I stay in the room? Yes. Many children feel more relaxed with a parent nearby, and it helps you see what we do. Some children do better on their own and we can discuss this as we go and I get to know you and your child.

    Will we need to do homework in between speech sessions? Yes, this is very important. Each week I will give you a couple of activities to do with your child which will help you practise what we do in the therapy room daily, and this is where progress is made!
