Are you tired of studying lengthy articles or books however need to analyze or enjoy them? Google has an answer for you! Google Cloud Text to Speech converts the text into natural-sounding speech. With the help of Google Cloud Voice, you could listen on your preferred articles, books, or maybe your website content material with out setting any stress for your eyes. In this weblog, let’s learn about Google Cloud Text to Speech and its API in detail.

What is Google Cloud Text to Speech (TTS)?

Google Cloud Text to Speech is a cloud based text to speech (TTS) service that allows developers to integrate natural-sounding speech to their projects. It is part of the Google Cloud AI Platform, which offers a collection of machine mastering and artificial intelligence offerings.

Using Google Cloud Text to Speech, developers can convert written text into natural-sounding speech in a variety of languages and voices. The service uses advanced deep learning techniques to generate speech that is indistinguishable from human speech.

Google Cloud Text to Speech gives a wide range of customization options, together with the capacity to regulate the velocity, pitch, and volume of the ensuing audio. It also offers multiple voice alternatives, which include male and female voices in distinctive languages and accents.

The service is easy to integrate into applications, with APIs available for multiple programming languages, including Java, Python, and Node.js. It also offers integration with other Google Cloud services, such as Google Cloud Storage and Google Cloud Functions.

How does Google Cloud Voice Work?

Google Cloud Text to Speech (TTS) is powered by the revolutionary WaveNet model developed in collaboration with DeepMind. Unlike traditional TTS systems that concatenate pre-recorded speech fragments, WaveNet generates speech one sample at a time. This enables it to create speech that is more natural-sounding and expressive than ever before.

WaveNet models are trained on massive amounts of speech data and can generate speech in various languages and styles.

How does WaveNet work?

WaveNet uses deep neural networks to synthesize speech from text. These networks learn the statistical patterns and linguistic rules of natural speech, which allow them to generate new speech samples that sound like a human voice.

Google Cloud Text to Speech can accept input text in two formats:

  1. Plain text
  2. Speech Synthesis Markup Language (SSML) document

Once it receives the input text, it synthesizes the speech in real-time. The generated audio is then returned to the user in the desired audio format.

But how does WaveNet produce such natural-sounding speech? It’s all in the details. WaveNet can model not only the fundamental frequency of the voice, but also the timbre, the voice quality, and even the breaths and lip smacks of a speaker. These details add a level of realism to the audio that was previously impossible to achieve.

Google Cloud Text-to-Speech offers a WaveNet-based voice option that allows developers to add even more natural-sounding speech to their applications.

With WaveNet, Google has set a new standard for TTS technology, making it easier than ever to integrate natural-sounding speech into your projects.

Project Setup for Google Cloud Text to Speech (TTS) API

Now that we have a basic understanding of the Google Cloud Text-to-Speech API, let’s dive into the project setup process.

Steps to setup project for Google Cloud Text to Speech (TTS) API:

  1. Sign in to Google Cloud Console.
  2. Select or Create a project.
  3. Enable the Text-to-Speech API.
  4. Link a service account to the Text-to-Speech API (Optional, if you have already linked).
  5. Set the authentication environment variable.

Let’s follow these steps to get everything up and running smoothly.
