title = "On split Dynamic Time Warping for robust Automatic Dialogue Replacement",
abstract = "In this article, we present LipSynch, a software tool that can be used for the automatic replacement of speech dialogues in motion pictures, video or television series. The system operates in two steps: during analysis, the timing relationships between the speech segments of the dialogues that serve as a timing reference and the corresponding speech segments in the replacement dialogues are measured by means of a split Dynamic Time Warping algorithm. The obtained warping paths are then processed and used to synthesize high-quality natural-sounding speech dialogues that are precisely time-synchronized with the reference dialogues. Subjective audio-visual listening tests performed within the context of a difficult Automatic Dialogue Replacement task demonstrated that LipSynch achieves a significant improvement compared to the industry-standard benchmark VocALign, both in terms of achieved lip-synchronization accuracy as well as in overall speech quality of the synthesized dialogues.",
