# google-squawk

You've heard of Google Chat, Google Voice, Google Talk? Well, this is Google Squawk! :-D
It's a commandline application that connects to the Google Cloud TTS API and generates audio from text.

Google cloud account credentials are required. You can specify the filename in an environment variable:

```
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/serviceaccount/credentials_file.json
```

Run ```gsquawk -h``` to see the help.

```
