There is no delay on my m2 macbook, presumably for some reason the audio synthesis is very slow on your machine. The next calibre release has a tool that allows you to pre-synthesize and embed the audio in the book, you can use that as a workaround. Also in the preferences of read aloud make sure the pause between sentences setting is at zero, maybe you accidentally increased that.
