Transcription of words with two consonants

  • At example with word Apple. It has transcription [ˈæpl]. But why there is one [p] in transcription during the word contains two "p". Eventually, do English speakers pronounce two p saying word as apple, propped etc, or just one. The same on words containing other double consonants like tt in letter. Thank.

  • the second consonant is not pronounced, but it affects the pronunciation of the preceding vowel:
    a pot [o] potter [o]; potable [ou]

  • Clear. Thank.
