FAVE-align, developed by the University of Pennsylvania is possibly the most accurate and powerful alignment tool to date. A major advantage of FAVE-Align is that it aligns chucks that are ‘breath group’ size (roughly a clause) as opposed to smaller units like words. So far FAVE-align has mainly been developed for vowel analysis (hence vowel extraction). Check out the University of Pennsylvania’s website for more information on the programme and how it works HERE

The University of Pennsylvania provides an online interface for forced alignment and vowel extraction. The size of your file and the speed of your internet connection determines how long the file takes to upload (so far I haven’t been able to upload more than about 10-15 minute long files). The site also provides the option to install the programme on your own computer although this takes a certain degree of tech know-how.

This site also has a range of useful resources such as transcription protocol and step-by-step guides on how to format your files for use with the online suite.
