The chart at the end of the book shows you the phonemes used in English, but the IPA pages host much more information about phonetics, including a link to the International Phonetic Alphabet that shows you all the symbols used to represent the sounds of the world’s languages.

Google Jenny Saffran to find her academic homepage with a link to useful publications, including Saffran et al. (1996), the study that got the child language world excited about statistics (strange, but true).
Google Patricia Kuhl, the linguistic genius of babies, for a TED talk on the infant’s remarkable language segmentation skills and how they change over the first year of life. Observe how Kuhl describes the loss of non-native discriminations in terms of a critical period in development.
