Programming Library to Edit Audio

We have some 10-minute wav files that contain speech. There are well-defined pauses in the speech. We need to write a program that separates out the speech between these pauses and outputs them as separate audio files. We also need to be able to save the elapsed time at the end of each pause.


This is fairly easy to do manually with a program like audacity, but we need an automated solution. Anyone have recommendations for a library/API?

See here: Automated Audio Segmentation Using Forced Alignment (Draft)

and here: Perl audio segmentation script - I think I got it working with 20-25 minute files, but the text much match the speech on the audio file pretty closely.
