What is a Phoneme?

A phoneme is the smallest unit of sound in a language that can change the meaning of a word. For example, changing the /k/ in "cat" to /b/ gives you "bat" - a completely different word!

English has 44 phonemes - sounds that combine in different ways to create all the words we speak and read. Mastering these 44 sounds is the key to reading fluency.

IPA Notation: Phonemes are written between forward slashes (like /k/) using the International Phonetic Alphabet (IPA). This helps us write sounds precisely, since English spelling can be inconsistent.

Tips for Learning Phonemes

👂 Watch Your Mouth

Use a mirror to see how your mouth moves for each sound. The app's mouth animations show the correct positions.

🗣 Listen Carefully

Pay attention to the difference between similar sounds like /b/ and /p/ or /f/ and /v/.

✍ Practice Writing

When you hear a sound, practice writing words that contain it to reinforce the connection.

🔁 Repeat Often

Say each sound multiple times. Repetition builds muscle memory for correct pronunciation.
