Advances in deep neural network approaches to speaker recognition
In this work, we report the same achievement in DNN-based SID performance on microphone speech. We consider two approaches to DNN-based SID: one that uses the DNN to extract features, and another that uses the DNN during feature modeling.

Improved speaker recognition using DCT coefficients as features
We recently proposed the use of coefficients extracted from the 2D discrete cosine transform (DCT) of log Mel filter bank energies to improve speaker recognition over the traditional Mel frequency cepstral coefficients (MFCC) with appended deltas and double deltas (MFCC/deltas).

Effects of feature type, learning algorithm and speaking style for depression detection from speech
We systematically study the effects of feature type, machine learning approach, and speaking style (read versus spontaneous) on depression prediction in the AVEC-2014 evaluation corpus.

Cross-corpus depression prediction from speech
We study a new corpus of patient-clinician interactions recorded when patients are admitted to a hospital for suicide risk and again when they are released.

SRI Leads Research Team to Next Phase of Wendy Schmidt Ocean Health XPRIZE Competition
The health of the world’s oceans impacts all of our lives, because oceans are much like the lungs of our planet, albeit acting in reverse—consuming carbon dioxide (CO2) and releasing oxygen. The Wendy Schmidt Ocean Health XPRIZE aims to improve understanding of how CO2 emissions are acidifying the oceans through a $2 million competition to create pH sensor…

Soft Robots Are Reshaping the Future of Robotics
Unlike traditional robots, nature offers hard and soft structures, actuators, sensors, and grippers that achieve many of these capabilities. Soft structures and systems are also inherently safer when interacting with people.

Future Ready Schools Learning Guide Offers Lessons for Connected Schools
President Obama, U.S. Secretary of Education Arne Duncan, and Office of Educational Technology (OET) Director Richard Culatta recently convened “ConnectED to the Future,” a gathering of more than 100 school district superintendents and other education leaders at the White House. On the agenda: increasing broadband connectivity access to and throughout schools as well as planning for the…
