Love the TTS for Chinese and Japanese!-- where can get? Add feature??

I love LR’s TTS voices for Chinese and Japanese! SO much better than Fluentu’s, for example. I’ve had apps in the past where you could just enter text and it would read aloud to you-- is there some way to get access to these TTS voices (or other, better-than-average ones)? Could LR add TTS read-alouds to the “Text” translation feature?
I don’t know much about TTS, not super computer literate. To whomever is kind enough to respond, feel free to explain everything like I’m five.

For anyone who finds this later, I think it’s “Liu,” one of the voices on Murf.AI
