'The book's emphasis on idiolect as individual's gradual and operational language variation through accumulative ways of meaning making within specific social cultural contexts, both provides readers with a convenient theoretical tool for forensic transcription, authentication and discourse analysis, and helps readers realize the complexity of forensic communication that necessitates the dialectical integration of different perspectives, paradigms, tools and approaches. [...] The book will be a useful resource for a variety of readers, including both researchers and practitioners who are interested in the theory and practice of forensic communication.'Renhua Wang, Nanjing Institute of Technology, ChinaDiscourse Studies 20/5 (2008)
