Questions, problems, solutions: 1. Many problems can be solved by upgrading to version 7.0 of Praat. 2. Make sure you have read the Intro from Praat’s Help menu. 3. If that does not help, use the Search button in Praat’s manual window. 4. Or consult the Frequently Asked Questions directly. 5. There is a user group on the Internet: the Praat Users List. 6. If none of the above helps, you can send email to paul.boersma@uva.nl.

## 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 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 Klatt acoustic 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 PDF, PNG or EPS 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
