More from developer
The stimuli presenter application displays speech spectrograms and enables playback of speech stimuli. It primarily targets tablet devices, as an interactive one-on-one aid for at-conference speech stimuli presentation, where playback of speech stimuli augmented with spectrogram plots is of interest.
Currently, both the audio stimuli (in 'wav' format) as well as the spectrograms (in 'png' format) are generated offline and must be uploaded to the /sdcard/Stimuli folder on the device prior to use. MATLAB scripts have been provided to make this task easier. The scripts along with sample stimuli are uploaded to the /sdcard/Stimuli folder on the device when the application is run.
