Tools that I use in my research:

1) DMDX 

Windows Software for running experiments developed by Jonathan and Ken Forster at the University of Arizona.

I've written a script to process the data from multi-subject .azk files into a form that is more easy to suck into Excel or SPSS. I've also been working with Mike Ford to set up DMDX for running fMRI experiments at the Wolfson Brain Imaging Centre. There are also some notes and guidelines on using DMDX with fMRI. This and other useful links and information on DMDX can be found here.

2) The CELEX Lexical Database

A lexical database with lists of words, their frequency of occurrence, morphological structures, etc.

My colleague Maarten van Casteren has written useful programmes, to extract and use information from the CELEX database. You can read more here.

3) Mix and Match

These two programmes written by Maarten van Casteren automate two critical and laborious stages in generating behavioural and functional imaging experiments: (a) generating constrained yet pseudo-random trial sequencse (Mix), and (b) generating optimally matched item/subject sets for factorial experiments (Match). You can read more about these in forthcoming papers in BRMIC.

4) Praat

An extremely useful program for manipulating, and displaying speech. Tell your friends!

There is a script that I wrote for generating temporally segmented speech here. You can also read about some other forms of distorted speech that can be generated with Praat, Noise-Vocoded Speech, and Sine-Wave Speech.

5) Straight

High-quality software for speech manipulation developed by Hideki Kawahara.

6) SPM

Sofware for fMRI/EEG analysis.
