Opening Monologue Voiced in Switch Version

I've been playing through the Switch version and one thing I immediately noticed is that they bothered to add [voice acting to Keiichi's opening monologue in Onikakushi](https://youtu.be/-Ez_pjkxpo0?t=88). I thought this was a nice touch and considering you've added content from the Switch version before, could it be possible to integrate this into an update for the patch? I'm sure many would appreciate it.

該議題提及將Switch版本的配音加入補丁中。首先，定位現有的音訊資源和Onikakushi開場獨白的腳本。檢查音訊在程式碼庫中的整合方式，很可能在語音檔案或腳本定義的目錄中。確定所需的格式和放置位置，然後透過加入新的音訊檔案並驗證其在遊戲中是否正確觸發來進行測試。
