How to say the sounds
It is most important that children pronounce the sounds clearly. To help you support your child with this, the following links are to film clips that demonstrate the correct way to say the letter sounds.
The first clip features Tami Reis-Frankfort who is a reading specialist and trainer. She demonstrates how to pronounce the sounds of the English Phonic Code, when teaching children to read with Synthetic Phonics. There is a pause after each sound for you to repeat the sounds.
