Tips:

• Pronounce this word as four syllables, stressing the first one.
• The vowel in the second syllable — spelled “ir” — is pronounced as the unstressed R-Vowel
  /ɚ/ .
• Pronounce the vowel in the third syllable, which is spelled with the letter “a,” as the weak schwa vowel
  /ə/.
• Use the consonant glide
  /r/ to link from the second to the third syllable—from
  /ɚ/  to
  /ə/.
• In the final syllable a syllabic “l”—
  /l̩ /—takes the place of a vowel in forming the syllable.
