Speech Recognition with Segmental Conditional Random Fields: A Summary of the JHU CLSP 2010 Summer Workshop

This paper summarizes the 2010 CLSP Summer Workshop on

speech recognition at Johns Hopkins University. The key theme of

the workshop was to improve on state-of-the-art speech recognition

systems by using Segmental Conditional Random Fields (SCRFs) to

integrate multiple types of information. This approach uses a stateof-

the-art baseline as a springboard from which to add a suite of

novel features including ones derived from acoustic templates, deep

neural net phoneme detections, duration models, modulation features,

and whole word point-process models. The SCRF framework

is able to appropriately weight these different information sources

to produce significant gains on both the Broadcast News and Wall

Street Journal tasks.
