Praat 4.5.08

Praat is a computer program with which phoneticians can analyze, synthesize, and manipulate speech and create high-quality pictures for their articles and doctoral theses.
Main features:
- 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.
