"Experimental phonetics", in contrast to "impressionistic phonetics", is defined by the author as phonetic research that uses instruments to record, measure and analyze speech events. This is explained in the first chapter, which I found to be one of the more engaging in the book. If you've read other works on general and acoustic phonetics, e.g. Ladefoged's _A Course in Phonetics_ and _Elements of Acoustic Phonetics_, this book will probably be over 80% review. But different presentations of familiar material are often useful for consolidating existing knowledge. And there are new bits here and there, like information on different VOTs for the different stops. Overall, this is a carefully produced, solid work.
