Yes, as it says in the description above:
Unfortunately, voice acting for the game will be suspended for the time being. There have been some complications with scheduling and implementation and until those are worked out, none of the released routes will have voice acting. We hope to be able to patch the voicing into the game at a later date!
We're working on Shuye's route now and Haiyue will be released sometime after that. We will have release dates once a better estimate is available, but those should be some months down the pipeline still.
