An important task in speech processing is the segmentation of speech utterances into the appropriate sequence of phones. This segmentation is traditionally accomplished using some kind of phoneme-based forced alignment algorithm. However, the segmentation of long speech utterances, so-called monologues, is in general a non-trivial issue, cf. .
Audio books offer a rich resource of high-quality speech material with accompanying text resources. Unfortunately, the speech material of audio books is a set of very long speech files. Recently, different approaches to the segmentation of monologues were accomplished, e.g. in .
This thesis aims to investigate an approach to phone segmentation of long speech monologues using, e.g., a combination of a grapheme-based forced alignment procedure for first sentence- and/or word-level segmentation, followed by a phone-based forced alignment procedure for the final phone level segmentation.
