Transcription involves converting audio to text. Transcribing audio to text involves taking an audio file and converting it to a text document verbatim and in the same language that the original speaker used. The best audio to text conversion can take an audio file in Spanish and convert it into a Spanish text file. On the other hand, translation is the process of taking a piece of audio or written text and converting it into another language. For example, if you have a text document in English but want it converted to French, that is translation.
