What is the most common pronunciation of "Sandra" in British English?

When I meet someone called "Sandra" I never know whether to pronounce their name "Sand-ra" or "Sahn-dra". I'm guessing it used to be "Sahn-dra" but with the influence of Sandra Bullock more people now seem to say "Sand-ra". I think this is especially so in Australia where, in NSW at least, they say "dance" not "dahnce". Here in New Zealand I'm not so sure.


Solution 1:

There's actually a video that demonstrates how to pronounce both "Cassandra" and "Sandra" with a British accent.
