Pronunciation of Xi

Dear Fiona and dear Gwilym , may I ask you, Gwilym, about your pronunciation of the pinyin “Xi” which is never commented by Fiona. Today p.e. XiaoBao sounds like “ShaoBao” etc. Is this pronunciation still correct in a wider sense? Frederic gives us the pronunciation in the Say it Right Series, Three Groups of Tricky Initials at 2:56 .祝你们万德
