Tips:

• Pronounce the first vowel as
  /æ/—and not, for example, as
  /ɑ/.
• Pronounce the double “t” as a lightly tapped
  /d/ in quick speech.
• Be sure to pronounce the final vowel—spelled “er”—as the weak R-Vowel
  /ɚ/ —and not as
  /ə/.
• Pronounce a very firm, distinct
  /n/ and sustain it slightly—especially if it is followed by another consonant at the beginning of the next word or occurs at the end of a sentence.
