Also, the style of that segment was a continuous monologue but changing speakers on each sentence. The speakers all had very similar voices, so it sounded very much like a single speaker. It was an interesting effect, though we lost the message because we started discussing whether they were processing the voices to be more similar or if Apple is just big enough to say to their customers “We need a female developer, camera ready, and her voice needs to sound like this.” and get 6 hits.
