Matlab realtime speech tools are available

Dear list,

I prepared a set of realtime speech/auditory tools for my students. They are based on elementary signal processing algorithms and are free to modify/reuse. They consist of:
Audio recorder with realtime FFT analyzer
Realtime spectrogram with simulated auditory spectrographic representations
Realtime vocal tract shape visualizer
They are linked below.

I hope they are also useful for your. Have fun!

PS: The tools use ‘audiorecorder' object in Matlab for implementing realtime recording functionality. It makes the tools incompatible with older Maltab versions such as 2010 or before.
