I'm also interested in the answer to this question. I'm evaluating wakeword providers, and some have greater compatibility for x86 than for RPi. I'm assuming doing wakeword detection on the NUC would introduce unacceptable latency, but it would be nice to know if I'm wrong.
I thoroughly agree with you guys. Anyway there are few simple reasons why we did not implement custom Mic/audio streaming topic:
When using audio_common you just need to configure capture.launch file to use proper device, so our mic is hw:1,0. Running audio_capture it will create "/audio/audio" topic and on that topic you can listen to the mic, read data etc. There is already tutorial on that page how to set it up. You can also try this respeaker_ros and use some of this topics :
Are there plans for a microphone ROS topic or are we currently bound to the RPi in the head due to hardware/latency limitations?
