## Description This PR adds support for the Porcupine wakeword engine, thus f…ixing issue #1491. Porcupine is fast, very accurate and supports user-generated wakewords. That is, you can generate a wakeword listener model by just specifying an English text string. The bad thing is that Porcupine is closed source and generated wake words are only valid for 30 days (but you can always use the provided optimizer to generate a new one). ## How to test On Linux: Clone Porcupine into e.g. ~/.mycroft: cd ~/.mycroft git clone https://github.com/Picovoice/Porcupine.git Generate a wake word file: ./Porcupine/tools/optimizer/linux/x86_64/pv_porcupine_optimizer \ -r ./Porcupine/resources/optimizer_data -w "hey mycroft" -p linux -o . In ~/.mycroft/mycroft.conf, set the "hey mycroft" wakeword section as follows: "hey mycroft": { "module": "porcupine", "porcupine_path": "~/.mycroft/Porcupine", "keyword_file_path": "~/.mycroft/hey mycroft_linux.ppn" }, ## Contributor license agreement signed?

Alas porcupine no longer has a way to creating a wake word within the command terminal.

There are existing wake words that are inlcuded with porcupine, although I have no idea as how to set up mycrof.conf to use the included wake word, any pointers?

current mycroft.conf settings:

“hotwords”: {
“hey mycroft”: {
“module”: “porcupine”,
“porcupine_path”: “~/.mycroft/Porcupine”,
“keyword_file_path”: “~/.mycroft/Porcupine/resources/keyword_files/raspberry-pi/blueberry_raspberry-pi.ppn”
}

I guess the question is how to get porcupine to load and use an included wakeword on a raspberry pi. tnx much++ for any help++

Turns out there is an issue with the new Procupine repo working with Mycroft. Issue has been raised here in mycroft github issues for anyone wanting to follow the thread.
