TransTool (Jens Allwood, Elisabeth Ahlsén, Joakim Nivre)
The Swedish Spoken Language Corpus, developed at the Department of Linguistics, Göteborg University, has several interesting tools: Transtool, to aid in transcription; Synchtool, for synchronizing transcriptions with audio and video files; TRASA, a tool for automatic analysis of the corpus; and TRACTOR, a tool to support coding.
