I don't think the pi has a mic input, however with an usb or bluetooth microphone and this node it should work.  
`node-red-contrib-micropi`

> Yes because the watson stt node expects a single wav buffer object but straight from the mic node you get raw pcm audio chunks as a stream of buffers. So you need to join the buffers and add wav headers to it. You will need to install [https://flows.nodered.org/node/node-red-contrib-wav](https://flows.nodered.org/node/node-red-contrib-wav) in nodered. Than import this flow: [{"id":"c4303dc0.528f58","type":"Mic","z":"20693e98.c7fb2a","name":"","outputPayloadType":"buffer","endian":"little","bitwidth":"16","encoding":"signed-integer","channels":"1",…
