Which mode of interpreter delivery involves real-time interpretation as the speaker is talking?

The mode of interpreter delivery that involves real-time interpretation as the speaker is talking is simultaneous interpretation. In this method, interpreters listen and verbally translate the speaker's message almost instantaneously, allowing the audience to receive the interpretation without any noticeable delay. This is particularly beneficial in environments such as conferences or live events where maintaining the flow of conversation is crucial.

In contrast, consecutive interpretation requires the speaker to pause after a segment of speech so that the interpreter can relay the message, which can disrupt the natural flow of dialogue. Sight translation involves interpreting written text aloud, typically used when an interpreter reads documents and translates them on the spot but does not apply to ongoing spoken communication. Written translation, on the other hand, refers to converting written materials from one language to another and is not meant for real-time dialogue. Thus, simultaneous interpretation stands out for its real-time delivery aspect, making it the correct choice in this context.
