For example, [13] uses a subsection of the ATIS corpus, takes as input the actual speech signal (and thus has access to silence duration but not to words), and uses as its evaluation metric the percentage of time the program identifies the start of the interregnum (see Section 2.2).
[9,10] use an internally developed corpus of sentences, work from a transcript enhanced with information from the speech signal (and thus use words), but do use a metric that seems to be similar to ours.
