Praat: doing phonetics by computer

PRAAT
Software para hacer análisis de señales de voz

Speech analysis: spectral analysis (spectrograms) pitch analysis formant analysis intensity analysis jitter, shimmer, voice breaks cochleagram excitation pattern	Speech synthesis: from pitch, formant, and intensity articulatory synthesis
	Listening experiments: identification and discrimination tests
Labelling and segmentation: label intervals and time points on multiple tiers use phonetic alphabet use sound files up to 2 gigabytes (3 hours)	Speech manipulation: change pitch and duration contours filtering
Learning algorithms: feedforward neural networks discrete and stochastic Optimality Theory	Statistics: multidimensional scaling principal component analysis discriminant analysis
Graphics: high quality for your articles and thesis produce Encapsulated PostScript files integrated mathematical and phonetic symbols	Programmability: easy programmable scripting language communicate with other programs (the sendpraat source code) create hypertext manuals with sound I/O
Portability: machine-independent binary files read and write many sound and other file types	Configurability: grow or shrink menus save prefs for fonts, views, sound devices
