In this tutorial, we will learn how to create a text-to-speech application using Python and the Google Cloud Text-to-Speech API. The Google Cloud Text-to-Speech API allows us to convert text into natural-sounding speech.<\/p>\n
By the end of this tutorial, you will have a working text-to-speech app that can read out any text you provide.<\/p>\n
Before we begin, make sure you have the following prerequisites:<\/p>\n
To get started, we need to create a new project in the Google Cloud Platform Console.<\/p>\n
Click on the project drop-down and select “New Project”.<\/p>\n<\/li>\n
Give your project a name and click on the “Create” button to create the project.<\/p>\n<\/li>\n
Once the project is created, select it from the project drop-down.<\/p>\n<\/li>\n
Enable the Text-to-Speech API by going to the API Library and searching for “Text-to-Speech”. Click on the API and then click on the “Enable” button.<\/p>\n<\/li>\n
Next, we need to create a service account key. Go to the IAM & Admin > Service Accounts section and click on the “Create Service Account” button.<\/p>\n<\/li>\n
Give your service account a name and click on the “Create and Continue” button.<\/p>\n<\/li>\n
Add the “Text-to-Speech Admin” role to the service account and click on the “Done” button.<\/p>\n<\/li>\n
Click on the three dots next to the newly created service account, click on “Create Key”, select “JSON” as the key type, and click on the “Create” button. This will download a JSON key file to your computer.<\/p>\n<\/li>\n
Finally, set the Make sure to replace Next, we need to install the required libraries to interact with the Google Cloud Text-to-Speech API.<\/p>\n Open your terminal and run the following command:<\/p>\n This command will install the Now that we have set up the Google Cloud project and installed the required libraries, let’s start building our text-to-speech app.<\/p>\n First, create a new Python file called Next, let’s import the required modules and create an instance of the Text-to-Speech client:<\/p>\n The Now, let’s define a function that takes a text input and converts it to speech:<\/p>\n In the above code, we define the Inside the function, we create an instance of the Next, we set the audio file format to MP3 using the Finally, we call the We then write the audio content to the output file.<\/p>\n Now, let’s add the main part of our script that interacts with the user:<\/p>\n In the above code, we use the Finally, we print a success message to the console.<\/p>\n To run the text-to-speech app, open your terminal and navigate to the directory where you saved the Execute the following command:<\/p>\n You will be prompted to enter the text and the output file path. After entering the inputs, press enter to start the conversion process.<\/p>\n The app will send a request to the Google Cloud Text-to-Speech API and save the synthesized audio to the specified output file.<\/p>\n Once the conversion is complete, you will see the success message on the console.<\/p>\n Congratulations! You have created a text-to-speech app using Python and the Google Cloud Text-to-Speech API.<\/p>\n In this tutorial, we learned how to create a text-to-speech app using Python and the Google Cloud Text-to-Speech API.<\/p>\n We set up a Google Cloud project, installed the necessary libraries, and wrote Python code to convert text to speech.<\/p>\n By following this tutorial, you can now build your own text-to-speech applications and explore the various features and options provided by the Google Cloud Text-to-Speech API.<\/p>\n","protected":false},"excerpt":{"rendered":" In this tutorial, we will learn how to create a text-to-speech application using Python and the Google Cloud Text-to-Speech API.

Installing the Required Libraries<\/h2>\n
pip install google-cloud-texttospeech\n<\/code><\/pre>\n
google-cloud-texttospeech<\/code> library, which we will use to programmatically interface with the Text-to-Speech API.<\/p>\n
Creating the Python Text-to-Speech App<\/h2>\n
text_to_speech_app.py<\/code>. Open the file in your favorite text editor or IDE.<\/p>\n
from google.cloud import texttospeech\n\n# Create the Text-to-Speech client\ntext_to_speech_client = texttospeech.TextToSpeechClient()\n<\/code><\/pre>\n
texttospeech<\/code> module provides the necessary classes and methods to interact with the Google Cloud Text-to-Speech API. The above code creates an instance of the
TextToSpeechClient<\/code> class, which we will use to make API requests.<\/p>\n
def text_to_speech(text, output_file):\n # Set the input text\n synthesis_input = texttospeech.SynthesisInput(text=text)\n\n # Set the voice parameters\n voice = texttospeech.VoiceSelectionParams(\n language_code=\"en-US\",\n ssml_gender=texttospeech.SsmlVoiceGender.NEUTRAL\n )\n\n # Set the audio file format\n audio_config = texttospeech.AudioConfig(\n audio_encoding=texttospeech.AudioEncoding.MP3\n )\n\n # Perform the text-to-speech conversion\n response = text_to_speech_client.synthesize_speech(\n input=synthesis_input, voice=voice, audio_config=audio_config\n )\n\n # Write the response to the output file\n with open(output_file, \"wb\") as f:\n f.write(response.audio_content)\n<\/code><\/pre>\n
text_to_speech<\/code> function that takes two parameters: the text to convert and the path to the output file.<\/p>\n
SynthesisInput<\/code> class with the input text. We also set the voice parameters using the
VoiceSelectionParams<\/code> class and specify the language code and gender.<\/p>\n
AudioConfig<\/code> class.<\/p>\n
synthesize_speech<\/code> method on the
TextToSpeechClient<\/code> instance and pass in the synthesis input, voice, and audio configuration. The method returns a
SynthesizeSpeechResponse<\/code> object, which contains the synthesized audio content.<\/p>\n
if __name__ == \"__main__\":\n text = input(\"Enter the text to convert to speech: \")\n output_file = input(\"Enter the path for the output audio file: \")\n\n text_to_speech(text, output_file)\n\n print(\"Text-to-speech conversion successful!\")\n<\/code><\/pre>\n
input<\/code> function to get the text and output file path from the user. We then call the
text_to_speech<\/code> function with these inputs.<\/p>\n
Running the Text-to-Speech App<\/h2>\n
