Learn how each sound is made, common errors, and how to help your child
Speech sounds develop in a predictable order. Some sounds emerge early (like P, B, M), while others take longer to master (like R and TH). Understanding how each sound is made and what errors to watch for can help you support your child's development.
Each guide explains how the sound is produced, shows common errors, provides practice activities, and helps you know when to seek professional help. Click any sound below to learn more.
