Sound Tools eXtended (STx) 5.0 — A Powerful Sound Analysis Tool Optimized for Speech

In this paper, we introduce Sound Tools eXtended (STx) version 5.0, an acoustic speech and sound processing application. STx 5.0 contains an integrated, simplified and compact GUI, specifically designed for speech analysis for phoneticians, linguists, psychologists, and researchers in related fields. It features a well structured user interface, compatibility with established tools (TextGrid [1], MAUS [2]), and top-notch signal analysis tools. STx 5.0 enables researchers as well as students to conduct advanced analysis of audio files, especially of speech recordings. STx 5.0 implements a new interface for the already established profiles in STx 5.0, which helps customize settings according to the researcher’s needs.
