There are several facts you may need to know about Google Cloud Text-to-Speech.
1. Google Cloud Text-to-Speech offers two types of voice, Standard and WaveNet. The standard voice sounds like a robot, but the price is low. The WaveNet voice sounds like a real person, but the price is a bit higher.
2. Google Cloud offers 1 million characters per month for free use. After that, you will be billed $4.00 per 1 million characters for standard voice or $16.00 per 1 million characters for WaveNet voice. This is the same as AWS Polly.
3. Google Cloud offers you $300 for the first three months when you create an account.
4. Differ from AWS Polly, no matter how many characters in one text, all TTS voice file will be stored on your server, AWS S3 or Wasabi depending on your setting.
Let's assume you already have an AWS account. Create it if you haven't. https://cloud.google.com/

Steps of configuration on CyberBukit TTS
Considering the safety reason, the Google Cloud credential file should be saved outside the web directory. Please follow the steps to finish the configuration.
1. As an example, The name of the file we just downloaded is 'clever-oasis-301913-db6dfcb7783e.json', we upload it to '/var/www/config/', So the 'Configuration File Path' is '/var/www/config/clever-oasis-301913-db6dfcb7783e.json'. Do make sure this directory(/var/www/config) cannot be visited from the internet.
Please note this path(/var/www/config/clever-oasis-301913-db6dfcb7783e.json) is only an example, it varies depending on your server. Overall, it should be the file's absolute path in your server.
2.Sign in as super admin on CyberBukit TTS, go to TTS Management -> TTS Configuration, at 'Google Text-to-Speech Setting (TTS Only)' part, fill in like the following:
