# command
|
||||
|
||||
This is a basic Voice Assistant example that accepts voice commands from the microphone.
|
||||
More info is available in [issue #171](https://github.com/ggerganov/whisper.cpp/issues/171).
|
||||
|
||||
```java
|
||||
# Run with default arguments and small model
|
||||
./command -m ./models/ggml-small.en.bin -t 8
|
||||
|
||||
# On Raspberry Pi, use tiny or base models + "-ac 768" for better performance
|
||||
./bin/command -m ../models/ggml-tiny.en.bin -ac 768
|
||||
```
|
||||
|
||||
## Building
|
||||
|
||||
The `command` tool depends on SDL2 library to capture audio from the microphone. You can build it like this:
|
||||
|
||||
```bash
|
||||
# Install SDL2 on Linux
|
||||
sudo apt-get install libsdl2-dev
|
||||
|
||||
# Install SDL2 on Mac OS
|
||||
brew install sdl2
|
||||
|
||||
make command
|
||||
```
