Links:

• Private corpus files for enrolled students only
• Praat (free)
• Matlab (glitzy and expensive, but free for UA folks)
• IPA font for MSword users and TIPA IPA font for LaTeX users (The tipa fonts are part of the core TEX distribution, but you can add them on with that link if your distribution doesn't include them.)
• VTAR matlab package to calculate and visualize vocal tract filtering. (GUI version crashes under Matlab version R2014b. There's a non-GUI version included in the package, but I haven't ascertained if it works under R2014b.)
• Classic older synthesis examples
• More recent synthesis examples
• Foma finite-state toolkit
• Some awesome matlab speech-tech tools by Lawrence Rabiner
