We are working with a small company called Appscio on an open source ASR system. In this talk, I will discuss GStreamer and MPF, the frameworks under which the system is implemented, as well as details on the actual ASR system including run-time, training, and IP issues.

GStreamer is a well-supported and popular cross-platform open source framework for media streaming. A large number of media applications (especially cross-platform ones) use GStreamer under the hood. The plugin architecture of GStreamer allows easy construction and even easier composition of media components. MPF (Media Processing Framework) is Appscio's extension to GStreamer for multimedia analytics. While GStreamer is oriented towards streaming data (i.e. frame synchronous), MPF provides services for structured metadata events (e.g. face detection, ASR, regions of interest, etc.).
