Abstract-This paper presents experiments with a customisation of a corpus-based unit-selection text-to-speech (TTS) system for automatic dubbing of TV programmes. The project aims at people with hearing impairments as its main goal is to produce a highly intelligible, less-dynamic, and more-undisturbed audio track for TV programmes automatically from subtitles. A twophase synchronisation process was proposed to cope with audiovideo synchronisation issues. These phases include both off-line time compression of all utterances in a source speech corpus used for TTS and on-line time compression of speech that overlaps assigned subtitle time slots. Based on a case study, in which a TTS-generated audio track of a selected movie was analysed, a simplification of to-be-desynchronised subtitle texts was proposed in order to keep time-compression factors in a reasonable extent. In this way, abrupt changes in dynamics of the produced audio track are avoided.

In this paper, the project "Elimination of the
