Not sure if you're joking, but IMO this is throwing out the baby with the bath water.
I like the idea of hiding details from the hiring filter and selection process that may contribute to bias, but never seeing or hearing the people I'm working with!? Sounds truly terrible.
Also, unless your voice changer actually selects/changes the words/pronunciation of the speaker, it will still be easy to identify details about them.
Accent, word-choice (soda vs pop), urban fast-talk, rural drawl all can be picked up even with a distorted voice.
I also want to do away with discrimination. But people’s faces and voices express emotion, character, and warmth
Your utopia sounds absolutely horrible.
I met my wife at work, she is a different ethnicity and culture than me.
I think there's definitely benefits to making open application positions more anonymous, but purely anonymous employment sounds terrible. You can already kinda get that with some outsourcing firms, and it's only useful for a very limited set of tasks.
You won't hear objections from me.
Actually, now with remote work, even after the applicant is hired, we still never have to see or hear them at all! We can just keep referring to them as Employee #1672378623, use a randomly-generated avatar for our Zoom meetings, and filter everyone's voice through voice-changer software. Bias-be-gone!
