Bumblebee Hotword is a stripped down and repackaged version of the excellent Porcupine wake word (hotword) system.

When Bumblebee Hotword is added to a web page, it listens to the microphone and emits an event when it hears any of the available hotwords.

QUESTION
Okay, so I've been trying to do this for a long time but I just can't find a solution. I'm building a personal Voice Assistant that only records when a hotword is detected, and everything until here works fine. To record the audio, I'm using the npm package node-record-lcpm16. I can't seem to find a solution to pause or stop(and start again) the recording. On the npm website of the audiorecorder there is a function specified that says recording.stop() but it doesn't work for me. My code right now is:

Answered 2021-Feb-25 at 16:09I've played about with your code.. it's definitely a fun project to play with!
I would suggest maybe just modifying the code to record to a buffer, then send that to the google speech recognition engine.
The reason recording.stop() was probably not working for you is that you were calling it on the stream. If we separate the recording and recordingStream variables we can control the flow better.
I've updated the code so when we get the hotword, we stop recording, recognize the speech, then start recording again.
