Functionality

The following gives you an idea of the features of the Praat program. The links take you into the web copy of the manual. The same manual is also available from Praat's Help menus, in which case you can see the pictures and do searches.

# 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
