Google Cloud Text-To-Speech API Java examples

The Cloud Text To Speech API enables you to generate and customize synthesized speech from text or SSML.

These samples show how to list all supported voices, synthesize raw text, and synthesize a file.

Prerequisites

To get started, download and install it.

Create a project with the Google Cloud Console, and enable the TextToSpeech API.
Set up authentication. For example, from the Cloud Console, create a service account, download its json credentials file, then set the appropriate environment variable:
```
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/your-project-credentials.json
```
Build the samples
```
mvn clean package
```
