//! Run with:
//! cargo run --example read_wav <model path> <speaker model path> <wav path>
//! e.g. "cargo run --example speaker_model /home/user/stt/model /home/user/stt/speaker_model /home/user/stt/test.wav"
//! (The WAV file must have signed 16-bit sample)
//!
//! Read the "Setup" section in the README to know how to link the vosk dynamic
//! libaries to the examples
