In consecutive interpreting the interpreter takes notes while the speaker gives the speech and later repeats the translated text after the speaker completes his speech. This is used for speeches at receptions and banquets.

In simultaneous interpreting the interpreter listens to the person talking via headphones and translates his/her speech immediately into the target language without a time lag. This ensures the audience gets to hear the speaker's speech in their language. This is used for speakers addressing large audiences.
