Dialogue intelligibility of TV audio content is an issue especially for people with hearing impairments. This paper presents a new Dialogue Enhancement technology as an advanced Clean Audio solution to address this problem. This technology enables the audience to individually adjust the volume of dialogue, music, or sound effects within a single broadcast audio stream for improved speech intelligibility or customized listening control. Further, this paper reports results of experiments that have been conducted to test the integration of the technology into the production workflow to find out about user reactions and to verify whether it is as helpful as intended for a hearing-impaired audience.
