This is a Raspberry Pi 5 whisper C++ voice assistant - backwards compatible with Pi4. Say "green light on" or "red light on" and the corresponding GPIO pin will go high (output25 for green, output 24 for red). You can copy this file and modify it to use any number of phrases or outputs. Use a relay hat to control larger devices like, motors, solenoids, or buzzers.
See the video of how it works here: https://youtu.be/jpW9foRIwv0
- git clone https://github.com/ggerganov/whisper.cpp
- Install libraries:
- sudo apt-get install libgpiod2 libgpiod-dev
- sudo apt install gpiod
- sudo apt install libsdl2-dev
cd whisper.cpp
In the whisper.cpp directory open up the Makefile and add "-lgpiod" to the end of the line starting with CC_SDL (around like 347) and save the Makefile. This links the newly installed gpiod library. Otherwise you'll get a linking error.
CC_SDL=sdl2-config --cflags --libs -lgpiod
Download the model(s) that you'd like to use. Raspberry pi 4 only works well with tiny.en. Raspberry pi 5 works well up to small.en ./models/download-ggml-model.sh tiny.en ./models/download-ggml-model.sh base.en ./models/download-ggml-model.sh small.en
compile the stream program make -j stream
Run it in your terminal (pi 4 should stick with tiny.en.bin, pi 5 can go up to the small.en.bin model) ./stream -m models/ggml-tiny.en.bin --step 4000 --length 8000 -c 0 -t 4 -ac 512
