In classes, we realized that distinguishing the tone of voice employed by the lecturer is crucial to take good annotations, Ex: the chemical element inhabiting meteorites. Sometimes, we can omit important data because we do not know how to differentiate from a tone of voice expressing surprise to a tone of voice entailing bewilderment. Can you please discuss the most common punchy phrases that the speaker utilizes to introduce important information? I mean, what words, phrases, or linking words make you think what you are going to annotate is relevant?
