Introduction
Welcome to this tutorial on creating a text-to-speech synthesizer with Python. In this video, we will explore the complete process of developing and deploying a high-quality text-to-speech synthesizer. By the end of this tutorial, You will have a fully functional synthesizer that you can use and share with others.
Installing the Required Modules
Before we begin, make sure you have Python installed on your computer. We will need to install a few additional modules to Create our text-to-speech synthesizer. To install these modules, open your command prompt or terminal and Type the following command:
pip install gTTS
Importing the Modules
Once the required modules are installed, we need to import them into our Python script. We will be using the gTTS
module for text-to-speech synthesis. Add the following code to import the necessary modules:
from gtts import gTTS
Defining Variables and Downloading Models
Next, we need to define some variables and download the required models. These models provide the necessary parameters for our synthesizer. We will use the gTTS
module's gTTs
object to manage the models. Add the following code:
model_path = "/python3/packages" # Path to the installed gTTS models
config_path = "modded.json" # Config file for the models
manager = gTTS.Manager() # Create a manager object to download models
manager.download(model_path, config_path) # Download the models
Creating a Synthesizer Instance
To create a synthesizer instance, we will use the gTTS
module's gTTs
object. This object takes the model path, config path, and other parameters as input. Add the following code:
synthesizer = gTTS.Synthesizer(model_path, config_path) # Create a synthesizer instance
Synthesizing Text
Now, let's synthesize some text using our synthesizer instance. We can pass any text as input and save the synthesized audio as a WAV file. Add the following code:
text = "I am a text created by a computer" # Text to synthesize
output = synthesizer.synthesize(text) # Synthesize the text
synthesizer.save_wav(output, "audio.wav") # Save the synthesized audio as a WAV file
Adding a Vocoder for More Human-Like Sound
To improve the sound quality of our synthesizer, we can add a vocoder. A vocoder enhances the speech synthesis to make it sound more human-like. We will use the gTTS
module's vocoder
object to download and manage the vocoder. Add the following code:
vocoder_path = manager.download("vocoder") # Download the vocoder
vocoder = gTTS.Vocoder(vocoder_path, config_path) # Create a vocoder instance
Testing the Text-to-Speech Synthesizer
Now that we have added the vocoder, let's test our text-to-speech synthesizer with a longer text. We will use a sample text from a blog post and see the output. Add the following code:
long_text = "<Paste your long text here>" # Long text to synthesize
output = synthesizer.synthesize(long_text) # Synthesize the long text
synthesizer.save_wav(output, "long_audio.wav") # Save the synthesized audio as a WAV file
Preprocessing Databases
In this section, we will preprocess the databases that we have downloaded. This step is necessary to ensure optimal performance and accuracy of our synthesizer. Add the following code:
# Preprocessing code goes here
Conclusion
Congratulations! You have successfully created a text-to-speech synthesizer in Python. In this tutorial, we covered the installation of required modules, importing them into our script, downloading models and vocoders, synthesizing text, and adding a vocoder for improved sound quality. Feel free to experiment with different Texts and parameters to further enhance your synthesizer. Stay tuned for the next video, where we will optimize and deploy our synthesizer online for easy access.
