Query: No pinyin

A resource called "Streetwise Mandarin" focusing on slang and colloquial expressions should be oriented to teaching spoken Chinese. The text, however, is in Chinese characters and English, with no pinyin; only the vocabulary lists include pinyin.I am learning spoken Chinese and am not studying written Chinese. I really need a resource focusing on slang and colloquial expressions, but"Streetwise Mandarin" is useless for me.
