On the PC-version, there seem to be quite a few "fixed" instances of this. Meaning they will always happen on my play-throughs. Both badly-synched lips and subtitles but also skipped lines of dialogue (for which there are subtitles but which I never get to hear the characters speak). The most prominent one (and the only one I can remember off the top of my head): During SH's dialogue after the Myrkul fight, she will lament her fate and one of the earlier bits of dialogue she has ends with the sentence: "I am alone" (to which Tav can reply "You're not alone. You have me.").
And I don't think I've ever heard the "I am alone" line from her. Might be a mismatch between the subtitles and what Jennifer did or did not record, but to me it sounds like her voice line gets cut off prematurely.
