I am not using a callsign for my tests. I tuned the noise threshold already. My problem here is, that I need to know when a word is spoken, before any classification happens. I would like to use the MOVI to trigger a movement with an Exoskeleton, but to do so it is necessary to detect the speech onset (not the classification) as soon as possible. As a workaround, I attached another microphone to the Arduino and I am using a simple threshold to detect the speech onset (after smoothing the audio signal). It works well, but I would like to use the mic on the MOVI to detect the onset. Is it possible to get a feedback from MOVI, when the speech onset is detected ? If not, is it possible to get the raw audio signals from the mic ?
