Here's a picture of my remote meeting setup: two displays, two microphones, and five sets of loudspeakers with a patch bay.
This is my setup for a remote meeting. I also use nwmONE, an open-ear headphone, to monitor meeting sounds.

This movie demonstrates an open-ear headphone. The sound was recorded by an omnidirectional miniature condenser microphone I am holding. I am exposed to a babble noise consisting of 20 speakers through headphones. The attenuation of the leakage sound exceeds 40dB under the 3 kHz frequency range.

Open-ear headphones with ***PASSIVE*** acoustic circuits suppressing leakage sounds are a game-changer in speech communication research. I will present a technical report in Japanese at a virtual meeting. For your information, I found an English YouTube review (youtu.be/ppBwNsn4kEE).

This photo shows a 3D-printed enclosure for a one-inch full-range loudspeaker. The background images are a manufacturer's specification sheet and the measurement result.
I made a similar (handy) enclosure for a one-inch full-range loudspeaker.

I designed and printed an enclosure for a 1.5-inch full-range loudspeaker. The enclosure consists of three separable (screwed) parts. It is small and easy to bring around. I will have a lot of fun with this gadget.

Maybe I am playing too much, but I learnt a lot. Very fast learning cycle with a 3D printer, a robot arm and MATLAB!

Robot arm with 3D printed microphone supporter for sound field visualization
A 3D printed part for holding DPA 4060 miniature condenser microphone
3D printed head with and without an open-ear type headphone
I redesigned a microphone holder for sound field visualization and printed a head model for measuring an open-ear headphone mwn ONW by Sonority Inc. It is a fantastic gadget. It opens a new experimental paradigm for speech communication research.

Big changes are coming for WASPAA 2025!
This is my first official post at Bluesky with great news :)
We got the best paper award at IEEE SLT'24! This work elegantly and straightforwardly solves contextual biasing issues with dynamic vocabulary arxiv.org/abs/2405.13344. Congrats, Yui, Yosuke, Shakeel, and Yifan!
! I'm super happy!
📣 #SpeechTech & #SpeechScience people

I bought this. This can be a game changer in human speech communication research. But, I have to measure if it is true by using my RAPHSODIEE tools. Check links embedded in my COCOSDA presentation.
