Praat is an application with which phoneticians can analyze, synthesize, and manipulate speech and create high-quality pictures for their doctoral theses and articles.

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

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.
