Get a GCP service account

You need a GCP service account JSON key file as credential to authenticate against the API. A service account is a Google account, but for computers/containers, not humans.

1. Option one

   Ask your local GCP admin. lol

2. Option two

   Follow this guide, where you're going to:

   1. Create a GCP Project, with billing enabled
   2. Turn on the Text to Speech API
   3. Generated a service account that has project access (i.e. viewer)

Set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the absolute, not relative path of the key file. The variable is read by the @google-cloud/text-to-speech package, the APIs' official nodejs client used in this tool.

Usage

sudo npm install --global @junaga/tts

# # Assuming the following:
# $ ls -1
# service-account.json
# text-smd-or-ssml-files/

# use the `$PWD` variable to save 5 seconds of your life
export GOOGLE_APPLICATION_CREDENTIALS=$PWD/service-account.json

# The default `--voice` is `germanSales`
tts --voice tikTok text-smd-or-ssml-files/ mp3-output/

# Check out `mp3-output/`

Run tts --help for all options.
