Phonetic Substitution

A character is replaced by a similar-sounding character.

Learn

A character is replaced by a similar-sounding character.

Phonetic substitution errors occur when characters that sound similar are confused with each other. This is common when transcribing spoken data or working from dictation. Examples include C/K, F/V, M/N, B/P, D/T, and G/J confusions.

Common pairs: C↔K, F↔V, M↔N, B↔P, D↔T, G↔J

  • PACK → BACK (P confused with B)
  • CAME → KAME (C confused with K)
  • FIVE → VIVE (F confused with V)

How to recognize it

  • Character replaced with phonetically similar letter
  • Length remains the same
  • Often involves voiced/unvoiced consonant pairs

Common mistakes

  • Not considering phonetic relationships
  • Assuming spelling is always phonetic
  • Missing subtle sound-alike substitutions
