Free praat software for mac

Praat 5.1.11 is a sophisticated computer program with which you can analyse, synthesize, and manipulate speech, and create high-quality pictures for your articles and thesis.

Major Features:

1. Speech analysis:
   • spectral analysis (spectrograms)
   • pitch analysis
   • formant analysis
   • intensity analysis
   • jitter, shimmer, voice breaks
   • cochleagram
   • excitation pattern
2. Speech synthesis:
   • from pitch, formant, and intensity
   • articulatory synthesis
3. 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)
4. Speech manipulation:
   • change pitch and duration contours
   • filtering
5. Learning algorithms:
   • feedforward neural networks
   • discrete and stochastic Optimality Theory
6. Statistics:
   • multidimensional scaling
   • principal component analysis
   • discriminant analysis
7. Graphics:
   • high quality for your articles and thesis
   • produce Encapsulated PostScript files
   • integrated mathematical and phonetic symbols
8. Programmability:
   • easy programmable scripting language
   • communicate with other programs
   • (the sendpraat source code)
   • create hypertext manuals with sound I/O
9. Portability:
   • machine-independent binary files
   • read and write many sound and other file types
10. Configurability:
    • grow or shrink menus
    • save prefs for fonts, views, sound devices
