Praat 6.3.15

pplication with which phoneticians can analyze, synthesize, and manipulate speech.

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.
