This paper deals with a presentation of an experimental system (called WebSubDub) for creating a high-quality alternative audio track for TV broadcasting. The system is used to create subtitles for TV shows in such a format which allows to automatically generate an alternative audio track with multiple voices employing a specially adapted TTS system. This alternative audio track is intended for televiewers with slight hearing impairments, i.e. for a group of televiewers who encounter issues when perceiving the original audio track — especially dialogues with background music, background noise or emotional speech. The system was developed in cooperation with Czech television, the public service broadcaster in the Czech Republic.
