Google Cloud Text-to-Speech API - iOS Integration

Google Cloud Text-to-Speech API iOS Demo

This demo app showcases how to use Google Cloud Text-to-Speech API on iOS. Google’s TTS API is very powerful and the available voices sound extremely fluent and natural. More details on the API can be found here. There's also a tutorial available here.

How to enable the TTS API

As with any Google Cloud API, the API has to be enabled on a project within the Google Cloud Console and all the API calls will be associated to that project. To setup a project in the Google Cloud Console, you can follow all the steps described here, except that this demo app requires an API key instead of a service account key.

Summarized steps:

1. Create a project (or use an existing one) in the Cloud Console.
2. Make sure that billing is enabled for your project.
3. Enable the Text-to-Speech API.
4. Create an API key.

Running the app

1. Clone this repo

   $ git clone https://github.com/acotilla91/Google-TTS-Demo.git
   

2. Open project in Xcode.
3. Go to the SpeechService class and replace <YOUR_API_KEY> with the actual API key that was obtained from the steps above.
4. Run the app. Should work on both, the device and simulator.

Know issues

• The WaveNet voices work perfectly, but the standard voices tend to fail. Might be a temporal bug on Google's side, since this is still a beta API. Issue seems resolved.
