I think it's interesting that people in here "don't mind it" instead of actively liking it.
Here's a contrarian case
for TTS: people are drawn to strange and novel things. When you get into what's ostensibly yet-another-TA-like-but-this-time-it's-better-we-promise and you hear Microsoft Sam reading every line of the chat, you maybe don't think it looks very polished or useful, but you sure as hell remember it.
Maybe you're trying ZK out in a private room with your buddies, you start spamming weird characters and toilet humor, you have a good time. Maybe you get into a "lobster pot" wtfing at why this weird community is so fascinated with seafood and the TTS really adds to the bizarrity of the situation.
The Moonbase Alpha video has 5 million views. I've never played the game but if you tell me the name I'll go "oh, that TTS game? looked kinda fun." Add a loudspeaker icon that shows over the com of the player who's "speaking" in TTS and what you have is a fairly high-quality Youtube Poop generator. Make a video of a game on trololo with shots of coms saying long tirades about lobsters, post on /r/gaming and you'll get a decent amount of exposure, fingers crossed.
