Abstract and Keywords

EMU is a collection of software tools for the creation, manipulation, and analysis of speech databases. At the core of EMU is a database search engine which allows the researcher to find various speech segments based on the sequential and hierarchical structure of the utterances in which they occur. The interface to the user and other applications is the EMU query language. EMU includes an interactive labeller which can display spectrograms and other speech waveforms, which further provides displays for several articulatory data, and which allows the creation of hierarchical, as well as sequential, annotation for a speech utterance. EMU interfaces with Praat, WaveSurfer for annotation, and with the R language and environment for statistical computing and graphics. The EMU/R interface enhances the R functionality and enables statistical analyses of EMU speech data. Overall, EMU provides tools for each step necessary to speech data analyses.

Keywords: EMU, speech, database, phonetic software, R, hierarchical annotation, query language
