This really worked for me. I used it to brush up on Spanish before traveling to Central America. I had studied Spanish in school but never felt comfortable speaking. It seemed overly simple. However I followed the directions exactly. I was shocked at how effective it was. I had the confidence to speak in situations that would have caused me to grapple for words in the past. Successive units quickly add terms and expressions but the pace is amazingly manageable.
I absolutely love this audio book!! It had an American guy paired with a Japanese woman. The guy has been living in Japan for 11 years and the woman sounds so adorable, especially when she laughs. They not only tell you how to speak Japanese but they tell you about the culture and the island. The American talks about some mistakes he made and what other foreigners tend to make. I love that they have a conversation, then say it again but enunciate each syllable of each word, then they explain what it means.
I think a key aspect of helping someone learn a new language is enunciating and saying words slow enough for them to pick u the different sounds. Especially if the language has sounds that are not available in English.
