Abstract: Previous research has demonstrated that synthetic speech is
        less well recalled than natural speech.  Luce et al (1983)
        concluded that this was because synthetic speech increases
        the effort involved in encoding and/or rehearsal of
        presented information.  Results of the experiments described
        here, which involved ordered recall of lists of ten words
        spoken in either a synthetic or a natural voice, with
        repetition of the words as a measure of successful encoding,
        indicate that most of the memory deficit with synthetic
        speech is due to encoding difficulties, rather than problems
        with item retention.  There is evidence that encoding
        synthetic speech involves more processing capacity than does
        encoding natural speech, but that once it is encoded it is
        stored just as efficiently.
