7 Simple Guidelines for Pronouncing English Vowel Sounds

When a single vowel is followed by one or more consonants in the same syllable (CVC structure), the consonant "closes" the syllable, forcing the vowel to be short and lax.

When a syllable ends in a vowel without a closing consonant (CV structure), the syllable is "open" and the vowel says its alphabet name (tense long vowel).

When a single vowel is followed by a consonant and an ending silent 'e' (V-C-e pattern), the silent 'e' causes the preceding vowel to become long.

Traditional phonics rhyme: "When two vowels go walking, the first one does the talking (and says its name)." While not universal, it holds true for key digraphs:

When followed immediately by the letter 'r', vowels lose their normal short or long identity and merge with the rhotic sound:

• ar → /ɑːr/: car, park, hard, star
• or → /ɔːr/: fork, storm, born, short
• er, ir, ur → /ɜːr/: her, bird, turn, work (Notice they all share the exact same sound!)

In spoken English, unstressed vowels almost always collapse into the neutral schwa sound /ə/, regardless of which letter (a, e, i, o, u) is spelled.

Even identical vowels are held roughly 50% longer in duration when followed by a voiced consonant (/d/, /b/, /g/, /v/, /z/) than by a voiceless consonant (/t/, /p/, /k/, /f/, /s/).
