transcriber has 3 distinct synonyms spread across 2 of its 5 senses. Each sense below keeps its own list, because a synonym belongs to a meaning and not to a word: swapping one sense's substitute into another sense's sentence is how a thesaurus makes writing worse. WordNet records no antonym for it — antonymy is a relation between word forms rather than concepts, so it is deliberately sparse.
Counts are distinct word forms across every sense. A synonym that appears under three senses is counted once here and shown three times below, under each sense it belongs to.
a person who translates written messages from one language to another
someone who rewrites in a different script
someone who represents the sounds of speech in phonetic notation
someone who makes a written version of spoken material
a musician who adapts a composition for particular voices or instruments or for another style of performance
