Setup Instructions

See the developer guide and release notes at https://developers.google.com/actions/ for more details.


Lyrebird Vocal Avatar API Application

  1. If you don't have developer access to the Lyrebird Vocal Avatar API, ask for an access by sending an email to support@lyrebird.ai.
  2. Go to the Applications and create a new application.
  3. Note the CLIENT_ID and the CLIENT_SECRET given to you.
  4. In the .env in the functions folder, edit the LYREBIRD_CLIENT_ID and LYREBIRD_CLIENT_SECRET by using the ones just provided to you.

Dialog Flow - Actions on Google Setup

  1. Use the Actions on Google Console to add a new project with a name of your choosing and click Create Project.
  2. Click Skip, located on the top right to skip over category selection menu.
  3. On the left navigation menu under BUILD, click on Actions. Click on Add Your First Action and choose your app's language(s).
  4. Select Custom intent, click BUILD. This will open a Dialogflow console. Click CREATE.

    2. In the .env update your FIREBASE_PROJECT_ID by using the one just provided to you.
    3. Run firebase deploy --only functions and take note of the endpoint where the fulfillment webhook has been published. It should look like Function URL (lyrebirdVocalAvatarSample): https://${REGION}-${PROJECT}.cloudfunctions.net/lyrebirdVocalAvatarSample
  9. Go back to the Dialogflow console and select Fulfillment from the left navigation menu. Enable Webhook, set the value of URL to the Function URL from the previous step, then click Save.
