The spelling of the word "EFALPHA" may seem unusual, but it follows the principles of the International Phonetic Alphabet (IPA). The first two letters "EF" represent the IPA symbol for the voiced labiodental fricative sound /v/. The next four letters "ALPHA" represent the symbol for the open front unrounded vowel sound /æ/. Thus, the word "EFALPHA" is pronounced as /vælfa/, with the stress on the second syllable. The IPA allows for precise phonetic transcriptions of words in any language.
