Well, based on how the series is set up, lip reading should have no effect.
Yea, I spent too much time over analyzing this probably, but this is my thoughts. Assuming pheromones could control without the person actually hearing, that would mean that specific different pheromones could be released for the specific purposes he has in his mind based on his thoughts. But if that was true, he wouldn't even have to open his mouth to get people to do stuff, he could just think it. And that could account for anything like an audio or language barriers getting in the way, and the only stipulation would be him getting close enough to the people to release it and make it work. Which, would still technically be mind control and a decent explanation somebody could make up to account for it, but it seems that isn't the case because the audio is like the main catalyst in the show.
Otherwise, the pheromones are activated by the audible command, but if that was the case, it still wouldn't be able to get through ear plugs, being deaf, not being able to understand it like a different language etc.
I'm just sure the people who created the idea of him have also thought of these things, and I would think they have answers for this. It is just funny to me because I watched nearly all of the episodes without even giving a second thought to what could be major plot holes to his super power being so caught up in the show.
It actually kind of just dawned on me that ear plugs is all it would take to stop this guy that is so feared and kind of made me laugh because it would be so easy to defeat him over something so stupid. But Jessica Jones or any of the characters would be quite dumb if they didn't realize that, so it obviously must not be the case. There must be some other explanation. And it could simply be solved by the understanding that he doesn't have to say anything to make his power work, but the show doesn't ever show that as the case.
