Praat
Open source speech analysis software From Wikipedia, the free encyclopedia
Praat (/prɑːt/ PRAHT, Dutch: [praːt] ⓘ; transl. "Talk") is a free, open-source computer software package widely used for speech analysis and synthesis in phonetics[4] and other fields of linguistics. It was designed and continues to be developed by Paul Boersma and David Weenink at the University of Amsterdam.[4] Praat is compatible with a wide range of operating systems, including Unix, Linux, Mac, and Microsoft Windows. The software supports formant analysis, pitch extraction, and spectrogram visualization, along with speech synthesis, including articulatory synthesis.[5] Praat has been used in linguistic research on endangered and minority languages,[6] as well as for analyzing regional accents and phonetic variation[citation needed].
