A voice actor gets asked the same things by nearly every new client. What microphone do you use? Can you do a live directed session? How fast is your turnaround?
Audio on an actor website splits into two things that want different treatment.
Importing a track from SoundCloud onto your website sounds like it should be one step: ask for the file, receive the file.
Most actors already keep their headshots and their audio in a cloud folder, because that is where the photographer or the studio put them.
If you have audio on your account, it reaches your website. That is true on every design in the catalog, which matters more for some actors than others: for a voice actor the audio is not a supporting detail, it is the product.
