New Voice Message Detection (Perl)

We have written a perl script that detects new messages left on PhoneShell. This script converts new voicemail messages to the appropriate format and copies them to a folder that is accessible by the Matlab  routines.

Message Processing (MATLAB)

New messages are picked up by our main matlab routine, which performs the pitch and loudness analysis and extracts all the relevant features from the waveform. It also loads all the emotion models and classifies the new message.

MMS message generation (Perl)

Once the matlab processing is done, it dumps a message string and an image identifier into a folder. The identifier selects the smiley image that will attached to the MMS message to be sent out and the message sting is put on the subject line. We use metasend to generate the messages with attachments.
