The sentence in question: 式の話を英語で聞くことができる機械も用意しました。
My attempt at translation: "They also prepared a machine which can hear the ceremonys speech in english."
First, I am really skeptical of my translation "a machine which can hear...". I'd rather think that this is a machine with which YOU can hear the speech in english too, although this is indeed somehow included in the statement that "the machine" can hear the speech in english.
Second, What machine are they talking about? I think they offer interpreters broadcasting simultaneous interpreting on a channel or something the like. But why is this expressed through the term "machine"??? Or are they talking about a kind of machine I simply have no clue about???^^
