A surprisingly useful entry-level language resource.
The CD is short, 40 minutes of content, but is well-designed for fast acquisition of the basic questions, numbers, sentence patterns, and supports multiple listenings. The format is English, slow Malay, then faster Malay. I particularly like how repetitions use different nouns to reinforce the core sentence pattern ("please bring me a plate of rice", "please bring me a cup of tea", etc). I didn't hear lisping per se, but from the differences between the slower and faster pronunciations I can understand the observation.
The phrasebook is also surprisingly useful. It is 4.6x3.25 inches, a bit smaller than other phrasebooks, but the type is larger and is actually practical to read on the street. Chapters are broken out by topic area ("at the hotel", "email" etc) with both common questions and cultural context (mail options, how to behave in a mosque, menu tips). The dictionary includes both words and common questions you might use with those words. Well laid-out.
This is not a full course in the language. But if you're trying to quickly come up-to-speed with core phrases, the Collins phrasebook/CD series seems a winner.
