Speaking Skills Learned through Listening is a method that aims at improving the student's listening comprehension and conversational skills in Japanese. This book is the second volume of the pre-intermediate to intermediate level.
The book focuses on listening exercises, although the final objective is for students to enhance their spoken language skills.
One of the main features of this method is that the audio files include all kinds of conversation, from very formal conversations to very informal real-life situations you may encounter in the streets, on the train, at home etc.
