From the perspective of ESL speakers this is really bad. Most people become fluent in English by watching TV. If you need subtitles then your listening comprehension will suffer greatly. I grew up on Friends, Star Trek and Simpsons etc, all with very clear speech. Maybe we need some software to enhance speech and make it more legible. Not just increase its relative volume but also reduce mumbling. We shouldn't have to, but maybe with an automatic solution streaming services could more easily add the option...
