The only volume to offer hands-on information about the wide range of research philosophies, methods and tools used across linguistics, phonetics, and speech science, as applied to disordered speech and language.
* Covers core topics for students undertaking their own research, including experimental and qualitative methods, sociolinguistics, corpus construction and analysis, data recording, transcription and digital analysis of speech, and speech imaging.
* Considers the research ethics associated with working with people who have speech, language or other communication difficulties.
* Includes a detailed discussion of the dissemination of research results, and advice on the writing of theses and dissertations, and on the writing and publishing of journal articles, as well the peer review process.
