What I like best about this paper is that this super simple pattern matching approach is able to produce high-quality audio, while being fast enough for real-time processing at the same time.
It was great fun working with everyone involved in this project. Thanks!

We also asked volunteers to perform a listening test and 66.7% of the reconstructed words could be identified correctly in a forced-choice test with 4 options. pic.twitter.com/SQm18pDVni

The approach used also allows us to run the analysis with the three regions individually. Each of them performed above chance level, but M1 clearly provided most information for the decoding processes. pic.twitter.com/CJTgvf8QpE

This simple and fast approach reconstructs very high quality audio using the patient's own voice. You can listen to a few examples in the supplementary material. pic.twitter.com/HorVv3RtI4

Our approach is based on Unit Selection, where the best fitting unit of speech is just concatenated to the output. We determine the best fitting unit of speech by comparing the cosine similarity of high-gamma activity. This video illustrates the approach:

In this study, we used a very simple method from the speech synthesis community to reconstruct natural, intelligible speech from intra-op ECoG in IFG, pre-motor and motor cortex. pic.twitter.com/ZTeseh4Y51

To stimulate a realistic VR scenario, our task requires quite a bit of movement, despite of which workload classification worked similar to previous studies in EEG.

In this article, we present a VR version of the n-back task (available at osf.io/yhtz8/) and use it to investigate workload in an immersive environment with EEG. pic.twitter.com/zqbP9iOv7z
