(英文版) 状況別の日本語会話表現集 - Japanese for All Occasions: Mastering Speech Styles from Casual to Honorific
I'm currently studying Japanese and have just begun learning Keigo (Genki Book 2). I've been searching for additional examples/scripts of Keigo in usage with audio accompaniment at native speed. Japanese for All Occasions is a good complement for your existing study materials for elementary-intermediate level students who have already mastered Hiragana/Katakana and can recognise basic Kanji.
The book has a nice easy format of scripted situations (i.e. asking a taxi driver about landmarks) which are followed by explanations of the specific format of speech (casual or honorific) and then also some exercises are provided. Overall I've been using this book more as exercise material to read/listen and work with in conjunction with the Audio CD. The explanations are quite brief and it's best for someone that's already begun learning keigo and just wants more material to practise with.
