Praat Description

Praat is an application for speech analysis. According to its authors, praat is "doing phonetics by computer". Through its graphical interface, several speech analysis functionalities are available: spectrograms, cochleograms, and pitch and formant extraction. Articulatory synthesis, as well as synthesis from pitch, formant, and intensity are also available. Other features are segmentation, labelling using the phonetic alphabet, and computation of statistics. Praat is configurable and extensible through its own scripting language and has provisions for communicating with other programs.Praat will work fine wherever it is on your disk; just type praat or click the icon. If Praat's graphical interface appears poorly, try starting Praat with praat -motif.Here are some key features of "Praat":· Speech analysis:· spectral analysis (spectrograms) · pitch analysis · formant analysis · intensity analysis · jitter, shimmer, voice breaks · cochleagram · excitation pattern · Labelling and segmentation: · label intervals and time points on multiple tiers · use phonetic alphabet · use sound files up to 2 gigabytes (3 hours) · Learning algorithms: · feedforward neural networks · discrete and stochastic Optimality Theory · Graphics: · high quality for your articles and thesis · produce Encapsulated PostScript files · integrated mathematical and phonetic symbols · Portability: · machine-independent binary files · read and write many sound and other file types · Speech synthesis: · from pitch, formant, and intensity· articulatory synthesis · Listening experiments:· identification and discrimination tests · Speech manipulation:· change pitch and duration contours · filtering · Statistics: · multidimensional scaling · principal component analysis · discriminant analysis · Programmability: · easy programmable scripting language · communicate with other programs · (the sendpraat source code) · create hypertext manuals with sound I/O · Configurability:· grow or shrink menus· save prefs for fonts, views, sound devicesWhat's New in This Release:· More extensive logistic regression.
