Edge Impulse Inc. / Tutorial: Responding to your voice
This is the finished Edge Impulse project for the tutorial 'Responding to your voice'. From here you acquire new training data, design impulses and train models.
About this project
Hello, World!
Have you ever wanted to make your own "Ok, Google" or "Alexa" keyword spotting model? Clone this project to build an embedded ML project detecting the "Hello World" keyword phrase.
You can also follow our tutorial to guide you through building your keyword spotting model, from data collection to deployment on embedded devices.
Sensor & Block Information
- Microphone audio data (.wav files) @ 16000 Hz
