The eSpeakEdit program is used to prepare phoneme data for the eSpeak speech synthesizer.
It has two main functions: prepare keyframe files for individual vowels and voiced consonants. Each of them contains a sequence of keyframes which define how formant peaks (peaks in the frequency spectrum) vary during the sound.
Process the master phonemes file which, by including the phoneme files for the various languages, defines all their phonemes and references the keyframe files and the sound sample files which they use. eSpeakEdit processes these and compiles them into the phondata, phonindex, and phontab files in the eSpeak-data directory which are used by the eSpeak speech synthesizer.
