Strange one here. I’ve installed a ReSpeaker 4 Mic Array (v1) atop of a brand new Raspberry Pi 4 B (4gb) running Raspbian (Kernel v 5.4) following the instructions available here:
I can get all four channels record well and play back in Audacity. I can arecord hello.wav and play it back using aplay. I can even use the record.py script to generate an output.wav file and play it back with aplay. But that’s where the success ends and the weirdness takes over.
Once I sudo pip3 install pvrespeakerdemo and run picovoice_respeaker_demo, I get the ‘[Listening …]’ prompt but it won’t listen to me. However, it will listen to the YouTube video linked from the article.
In fact, it will run through the entire demo if I let it, with the unit on my desk doing exactly what’s happening in the video. Spooky.
Can anyone help me with this? I’ve been playing with it for two days unsuccessfully.
