Text-to-Speech is an API that is powered by Google's artificial intelligence
(AI) technology. You send your transcript data to Text-to-Speech in an API
call, then receive natural-sounding, synthetic human speech as playable audio in
response. For more information on how Text-to-Speech works, see the
basics page.
We provide code samples that show you how to
make a request to the API and receive a response. You can learn how to use
these samples by following the Text-to-Speech
quickstarts and
how-to guides.
This guide walks you through the steps necessary to start sending requests to
the Text-to-Speech API.
Overview
Before you can begin using Text-to-Speech, you must enable the API in the
Google Cloud Platform Console. The steps below walk you through the
following actions:
Enable Text-to-Speech on a project.
Make sure billing is enabled for Text-to-Speech.
Set up authentication for your development environment.
You can either choose an existing project or create a new one. For more
details about creating a project, please see the
Google Cloud Platform documentation.
If you create a new project, you will be prompted to link a billing account
to this project. If you are using a pre-existing project, make sure that you
have billing enabled.
Once you have selected a project and linked it to a billing account, you
can enable the Text-to-Speech API. Go to the Search products and
resources bar at the top of the page and type in "speech". Select the
Cloud Text-to-Speech API from the list of results.
To try Text-to-Speech without linking it to your project, choose
the TRY THIS API option. To enable the Text-to-Speech API for use
with your project, click ENABLE.
To disable the Text-to-Speech API, navigate to your Google Cloud Platform
dashboard and click on the Go to APIs overview link in the APIs box.
Click on the Text-to-Speech API, then select the DISABLE API button at the top
of the page.
