ppnrespeakerdemo 2.1.1

Porcupine wake word engine demo for ReSpeaker 4-mic hat.

Porcupine ReSpeaker Demo

Made in Vancouver, Canada by Picovoice

This package contains a commandline demo for controlling ReSpeaker 4-mic microphone array LEDs using Porcupine.

Porcupine

Porcupine is a highly-accurate and lightweight wake word engine. It enables building always-listening voice-enabled applications. It is

• using deep neural networks trained in real-world environments.
• compact and computationally-efficient. It is perfect for IoT.
• cross-platform:
  • Arm Cortex-M, STM32, PSoC, Arduino, and i.MX RT
  • Raspberry Pi, NVIDIA Jetson Nano, and BeagleBone
  • Android and iOS
  • Chrome, Safari, Firefox, and Edge
  • Linux (x86_64), macOS (x86_64, arm64), and Windows (x86_64)
• scalable. It can detect multiple always-listening voice commands with no added runtime footprint.
• self-service. Developers can train custom wake word models using Picovoice Console.

Installation

Follow the instructions on Seeed Studio to install and set up the microphone array.

Then install the demo:

sudo pip3 install ppnrespeakerdemo
