In contrast, speech recognition performance (especially for open-source-based solutions), is still poor on open-domain topics, but speech technology is able to align a given text to the corresponding speech with high accuracy. Let's join forces to generate superior subtitling with little effort, and to improve future open-source-based speech recognizers, at the same time!\n","original_language":"eng","persons":["timobaumann","Arne
