You are now ready to use Google Cloud Text to Speech in C#, with a more natural and less robotic voice. The service, in basic quality, is free up to 4 million characters per month, beyond the fee is $ 4 per million additional characters. Today, the service is free up to 1 million characters per month in WaveNet (Technology based on Machine Learning and to have a more natural voice), beyond the tariff is $ 16 per million characters additional. To use it in a Stream for example just call the following method. The service returns to us, in the AudioContent property, the audio content that is in the ByteString format.

The type of encoding can be defined in Linear16 (Wave), Mp3, etc. We can also specify the gender, that is to say, man or woman.

Once installed, you can use the TextToSpeech client provided by Google to access this service. The GOOGLE_APPLICATION_CREDENTIALS environment variable must contain the path to the previously generated private key.Įxample: “C: \ Credentials \ softfluent-127924-89b6632e0173.json”įor example, you can set the environment variable in C #: Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", "C:\Crd\32e0173.json") Īll you have to do is install in your project the NuGet TextToSpeech package from Google which is, as I write this article, in beta. Carefully keep the JSON file containing your private key, whose name is in the format: “e0173.json”.Ĭopy this file to a directory, for example: “C:\Credentials” Environment variable If you do not have one, create a service account for your applicationįinally, in the “Actions” section, click on “Create a key”.Ĭlick “Create” to generate your private key. In the “Service Account Keys” section on the screen that appears, click “Manage Service Accounts.” Go to your Google Cloud Platform account and click on “Identifiers” in the “API and Services” section. We will now manage authentication on Google Cloud Platform. The API is now active on your Google Cloud account. Go to your Google Cloud Platform account and click on “Dashboard” in the “API and Services” section. Under Text-to-speech, select Text-to-speech voice settings. In the 'Accessibility' section, select Manage accessibility features. At the bottom right, select the time or press Alt + Shift + s. You must first enable the API on your Google Cloud Platform account. Change the language, voice, or volume for Text-to-speech. Net Framework.įor information, there is the same service on Azure in beta too. Open any app, and then tap Select to Speak > Play to hear the phone read the text aloud. Tap the Select to Speak toggle switch to turn on the feature. The audio rendering is much better than the SpeechSynthesizer of the. On an Android phone, tap Settings (the Gear icon) and then tap Accessibility > Select to Speak. This project is leveraging the undocumented Google Translate speech functionality and is different from Google Cloud Text-to-Speech.Google has just released, in beta, a service on Google Cloud Platform to convert text into audio data, you can use Google Cloud Text to Speech in C# easily. Breaking upstream changes can occur without notice. This project is not affiliated with Google or Google Cloud. Customizable text pre-processors which can, for example, provide pronunciation corrections Ĭommand Line: $ gtts-cli 'hello' -output hello.mp3.Customizable speech-specific sentence tokenizer that allows for unlimited lengths of text to be read, all while keeping proper intonation, abbreviations, decimals and more.
Or simply pre-generate Google Translate TTS request URLs to feed to an external program. Write spoken mp3 data to a file, a file-like object (bytestring) for further audio manipulation, or stdout. GTTS ( Google Text-to-Speech), a Python library and CLI tool to interface with Google Translate's text-to-speech API.
