📢 Introduction to Google Cloud Text-to-Speech

The video begins with an introduction by Nian Roby from LearnVue, who outlines two methods for creating text-to-speech voiceovers using Google Cloud. The tool offers a wide selection of over 200 voices in more than 40 languages. The presenter emphasizes the need for a Google Cloud account and guides viewers through the sign-up process, including setting up billing information and enabling the Cloud Text-to-Speech API. The free version of the API allows processing up to one million characters for WaveNet voices, with an option to pay for additional usage. The video then instructs viewers on how to create and restrict an API key for security purposes and concludes the first method by showing how to use the WaveNet Chrome extension to convert text into speech and download the audio files.

🎧 Method Two: Using Audio Capture Extension

The second method described in the video is a straightforward approach to creating text-to-speech voiceovers. It involves installing an audio capture extension from the browser's web store and using the Google Cloud website without signing in. The presenter demonstrates how to input text into the 'Put text to speech into action' box on the Google Cloud site, choose the desired language and voice, and adjust the speed and pitch. To record the speech, the viewer is instructed to use the audio capture extension to start recording when the text-to-speech function is initiated. Once the recording is complete, the viewer can save the audio file. The video concludes with an invitation for viewers to subscribe for more content, ask questions, or seek help in the comments section.

💡Google Cloud

Google Cloud is a suite of cloud computing services that runs on the same infrastructure that Google uses internally for its end-user products, such as Google Search, Google Maps, and YouTube. In the video, it is the platform where the Text-to-Speech voiceover is created, and it is central to both methods described for generating voiceovers.

💡Text-to-Speech

Text-to-Speech (TTS) is a technology that converts written text into audible speech. In the context of the video, TTS is the process by which the user creates voiceovers using Google Cloud's technology, which is the main focus of the tutorial.

💡Voiceover

A voiceover is a production technique where a voice—that is not part of the main action of a movie, TV show, or video game—is used to narrate or provide additional information. In the video, the host is teaching viewers how to create voiceovers using Google Cloud's Text-to-Speech API.

💡API Key

An API key is a unique identifier used in the context of software development to authenticate a user, developer, or calling program to an API. In the video, the API key is necessary to access and use the Google Cloud Text-to-Speech API, and it must be kept secure to prevent unauthorized use.

💡Wavenet

Wavenet refers to Google's advanced neural network-based voice synthesis technology that can generate speech that is almost indistinguishable from human speech. In the video, Wavenet is used as an extension to facilitate the text-to-speech process.

💡Complimentary Credit

Complimentary credit is a promotional offer where a service provider gives users a certain amount of credit for free to use their services. In the video, Google Cloud offers a complimentary credit of $300 to new users, which can be used to process characters for the Wavenet voiceover.

💡Audio Capture Extension

An audio capture extension is a browser plugin that allows users to record audio from their computer. In the second method described in the video, the audio capture extension is used to record the voiceover generated by the Google Cloud Text-to-Speech API.

💡Language Selection

Language selection refers to the process of choosing the language in which the text will be converted to speech. The video script mentions the ability to select from over 200 voices in 40 plus languages, showcasing the versatility of the Google Cloud Text-to-Speech service.

💡Voice Selection

Voice selection is the process of choosing the specific voice that will be used to narrate the text in a text-to-speech application. The video emphasizes that users can select from a wide range of voices, allowing for customization of the voiceover.

💡Speed and Pitch

Speed and pitch refer to the rate at which the speech is delivered and the frequency of the sound waves that make up the voice, respectively. In the video, the host demonstrates how users can adjust the speed and pitch of the voiceover to suit their preferences.

💡SMP3

SMP3 likely refers to a file format for audio files. In the context of the video, the host instructs viewers to download the voiceover as an SMP3 file using the Wavenet extension for method one of the voiceover creation process.
