Prerequisites

Our sample needs some external dependencies to run properly, however we are packing them in sample. The one thing that you need to run this sample is dependency needed by our listen.py script, to gather audio data from your microphone.

sudo apt-get install python3-pyaudio

💡NOTE: Packaging of Python Sequences is not very "pythonic" for now. If you have any idea, how we should resolve it for your comfort, please let us know here.

Running

❗ Remember to setup transform-hub locally or use the platform's environment for the sequence deployment.

Open the terminal and run the following commands:

# go to 'voice-recognition' directory cd python/voice-recognition # install dependencies npm run build # Deploy sample to STH si seq deploy dist

Output

# You need to pass INSTANCE_ID to listen.py script. Gather it first si inst ls [{"id":"da9e41d8-e776-491f-b883-6e61afa93b97","sequence":"15228e0e-b7e3-4008-b4ee-e9aa1d0008d9"}] # Run listen.py script SCRAMJET_API_URL="http://localhost:8000/api/v1" INSTANCE_ID="da9e41d8-e776-491f-b883-6e61afa93b97" python3 listen.py # You should see something similar to this.

For test purpose, I said that I like pink elephants. You can notice that it is visible in STH logs.
