is a tool for the transcription and annotation of speech signals for linguistic research. It supports multiple hierarchical layers of segmentation, named entity annotation, speaker lists, topic lists, and overlapping speakers. Two views of the sound pressure waveform at different resolutions may be viewed simultaneously. Various character encodings, including Unicode, are supported.
Annotations may be exported in XML.
