samesounding

Samesounding is a term used in linguistics to describe two or more forms that share identical pronunciation. In many discussions, samesounding is effectively synonymous with homophony—the idea that different words can sound the same when spoken. Some writers, however, prefer samesounding to emphasize the auditory equivalence regardless of how the words are spelled or where they come from.

Samesounding can be further categorized by how exact the sound match is and by dialect. Perfect samesounding refers to identical phonemes in the same order across words, such as night and knight in many English varieties. Near-samesounding covers pairs that are nearly identical in pronunciation but may differ by a subtle phonetic distinction or by a regional accent. Dialect and speaker variation can cause words to be samesounding in one variety but not in another, so samesounding is often described as dialect-dependent.

Common examples include night and knight, pane and pain, see and sea, and pair, pear, and pare. These pairs illustrate how samesounding can involve different spellings and meanings, and sometimes even different parts of speech. Conversely, words that are spelled the same but pronounced differently (heteronyms) do not count as samesounding.

Applications of the concept appear in language learning, literacy, puns, and speech technology. Recognizing samesounding relationships helps with pronunciation practice, decoding homophonic errors in listening, and building more natural-sounding synthesized speech.
