(1995) dataset, which suggests that Fast Track can be very accurate in cases where signal properties allow for reliable formant estimates.īoersma, Paul & David Weenink. The design and use of Fast Track are outlined using a re-analysis of the Hillenbrand et al. In addition, Fast Track includes tools to aggregate data across tokens, and to easily create vowel plots of mean values or time-varying formant contours. Fast Track features a modular workflow that allows for analysis steps to be run (and re-run) independently as necessary, and is designed to allow for easy correction of tracking errors by allowing the user to override the automatic analysis, or manually edit tracks where necessary. Fast Track returns text files containing acoustic information (formant frequencies, formant bandwidths, fundamental frequency, etc.) sampled every 2 ms, generates images showing the winning analysis and comparing alternate analyses, and creates log files detailing analysis information for each file. The best track is selected by modeling smooth formant contours across the entirety of the sound, providing the researcher with rich information about static and dynamic formant properties. Fast Track is a formant tracker implemented in Praat that attempts to automatically select the best analysis from a set of candidates.
