Understanding the Difference Between /f/ and /th/ Sounds
The /f/ Sound
The /f/ sound is a voiceless labiodental fricative. This means you produce it by placing your top teeth lightly on your bottom lip and blowing air out. Your vocal cords do not vibrate when making this sound. Common examples of words with the /f/ sound include fan, leaf, and coffee.
The /th/ Sound
The /th/ sound can actually represent two different sounds in English: the voiceless /θ/ (as in think) and the voiced /ð/ (as in this). For this article, we’ll focus on the voiceless /θ/ sound, which is often confused with /f/ by English learners. The /th/ sound is a voiceless dental fricative, made by placing the tip of your tongue between your upper and lower teeth and blowing air out gently. Your vocal cords remain relaxed and do not vibrate.
Step-by-Step Guide to Pronouncing /f/ and /th/
How to Pronounce the /f/ Sound
- Place your upper front teeth gently on your lower lip.
- Keep your mouth slightly open.
- Blow air out through the small gap between your teeth and lip.
- Do not use your voice; the sound should be soft and airy.
Try saying these words: fun, free, laugh, life, phone.
How to Pronounce the /th/ Sound
- Stick the tip of your tongue out slightly between your upper and lower front teeth.
- Keep your teeth gently closed on your tongue, but not biting it.
- Blow air out gently over your tongue and through your teeth.
- Do not use your voice for the voiceless /θ/ sound (as in think).
Try saying these words: think, thin, both, bath, mouth.
Common Mistakes and How to Fix Them
- Substituting /f/ for /th/: Many learners pronounce think as fink. To avoid this, remember to use your tongue, not your lips, for /th/.
- Substituting /th/ for /f/: Some may pronounce fan as than. For /f/, ensure your tongue stays behind your teeth and only your lip moves.
- Not enough airflow: Both /f/ and /th/ are fricatives, which means you should feel air flowing out. Practice blowing out a candle with both sounds.
