uvx zai-tts -f path/to/file.txt -o {tempdir}/{filename}.wav
```

```shell
uvx zai-tts -t "{msg}" -o {tempdir}/{filename}.wav --speed 1.5
uvx zai-tts -t "{msg}" -o {tempdir}/{filename}.wav --speed 1.5 --volume 2
```

## Changing the voice
```shell
uvx zai-tts -t "{msg}" -o {tempdir}/{filename}.wav --voice system_002
```
