Takes a recording of up to 60 minutes and up to ten questions, and answers each
Takes a recording of up to 60 minutes and up to ten questions, and answers each one strictly from the transcript. Every answer cites the sentence numbers it relies on; those sentences are returned with their text and timestamps, and citations to sentences that do not exist are removed. When the recording does not contain the answer, the question is marked not answered instead of guessed. Answer language selectable.
