need help ripping layton pandora's box hd

[Alfendi]

im trying to get the voicelines from the hd version of the game because the ds ones are too compressed but when i unzipped the apk the only things i can find that look like voicelines are .awb files? and i cant find how to make them openable... ive tried a couple of file converters but they keep failing. is there something im missing here?
