No, not real time. But it does have STS/S2S,

Ok, I'm new to this. Is that 'speech to speech' and 'sequence to sequence'? thanks

this software basically boils down to making a character / voice actor sound like they're saying something you asked them to
if you want mickey mouse to say "but you're maidenless" you need to grab that voice clip from elden ring and run to this synthesizer
if Yosuke Hanamura to call you the "The Elderlord of ♥♥♥♥♥♥♥ CHAD NarukamiXX" instead of "partner", you'll need to get some elbow grease and and configure some mods for Persona 4 Golden specifically
if you wanna hear Nero saying "I should have saved you... I should have been the one to fill your dark soul wiTH LIGHT!!" just play Megaman-X7 lol grab the voice sample and synthesizer with Ichigo Kurosaki calling for Orihime Innue

i've personally been wondering if you can put these into a games voice chat
imagine playing TF2 then hearing a certain someone in the voice chat say "The calvalry's here!"
