I noticed the same thing with Espa. I don't know if they are all the original actors. I think most of them are, but when I hear stuff like this, I think that some substitutes are at work.
Espa’s sounded the same to me but syrus’s is too high pitched. Maybe it is the OVA. Probably went into the sudio, rushed the lines then came out. Done it from memory
