The Sound th (soft) In American English

The Sound of th

The multigraph "th" make the sound /θ/ in English which is an unvoiced sound close to the English /s/ sound, but produced with the tongue touching the upper teeth. This pronunciation drill focuses on this sound and practices it across a range of syllable structures to build control in different phonetic environments. The drill includes the following patterns:

Vowel + Consonant (VC)

Consonant + Vowel (CV)

Vowel + Consonant + Consonant (VCC)

Consonant + Consonant + Vowel (CCV)

Practicing /θ/ in these patterns helps you stabilize the sound in both simple positions and more complex consonant sequences, where precision of tongue placement and airflow becomes especially important.

Begin with VC and CV combinations, focusing on clear placement of the tongue between the teeth and maintaining continuous airflow. Move next to VCC patterns, where /θ/ appears alongside other consonants and requires careful timing to avoid distortion or substitution with /s/ or /t/. Finally, CCV combinations train you to produce /θ/ after consonant clusters while keeping the sound stable and distinct.

Example

faiths

Long o + th + s → /oʊθs/

Example

oaths

aʊ + th + s → /aʊθs/

mouths

Step 6: Consonant + Consonant + Vowel

Read each word aloud at least 3 times, The words in this sent include initial consonant clusters, so they might require more practice.
