Setting Up Google Text-to-Speech API: A Beginner’s Guide

Estimated read time 3 min read


In today’s fast-paced world, time is of great importance. People are always looking for ways to save time and increase productivity. One way to achieve this is by using voice assistants or text-to-speech (TTS) technology. In this article, we will guide you through the process of setting up Google’s Text-to-Speech API so that you can start using it in your projects.

Getting Started:

The first step is to create a new project in the Google Cloud Console. Once you have done that, navigate to the APIs & Services Dashboard and click on "Enable APIs and Services." From there, search for "Text-to-Speech API" and enable it.

Next, we need to create a credentials file that will allow us to authenticate with the API. This file can be downloaded from the APIs & Services Dashboard under "Credentials." Once you have downloaded the file, install it on your machine by running the command "google-credentials application_default login" in the terminal.

Now that we are authenticated, we need to configure our TTS settings. We can do this by sending a request to the API with the appropriate parameters. The API allows us to customize the voice, speed, and volume of the text being spoken. We can also specify the language of the text.

Here is an example request:

"input": {
"text": "Hello, world!"
"audioConfig": {
"outputType": "mp3",
"audioEncoding": "LINEAR16",
"sampleRateHertz": 44100,
"languageCode": "en-US"

This request will convert the text "Hello, world!" to speech in English and save it as an MP3 file.

Advanced Features:

The Text-to-Speech API also offers some advanced features that can be useful for more complex projects. One such feature is synthesis markup, which allows us to add emphasis or other formatting to the text being spoken.

Here is an example of synthesis markup:

<language code"en-US">Hello, world!</language>
<audio config>
<audioFormat encoding"mp3"/>
<bold>Hello, world!</bold>

This markup will emphasize the text "Hello, world!" when it is spoken.


In conclusion, setting up Google’s Text-to-Speech API is a simple process that can greatly improve your productivity and save you time. With just a few lines of code, you can convert text to speech in any language and customize the voice, speed, and volume of the output. Whether you are an AI developer or simply looking for a way to increase efficiency, this API has something for everyone.
