Google Colab: Your Free Development Environment

To make this Tutorial even more accessible, we'll leverage Google Colab, a free cloud-based development environment that provides access to powerful computing resources. Google Colab allows you to run Python code without the need for local installation

. This is particularly useful for resource-intensive tasks like voice cloning. Since you are connected to GPU Runtime, using it to download and install all of the dependencies required is easy and faster than running locally. Colab does not require any specific GPU to be utilized.

Step-by-Step Guide to Voice Cloning with Coqui TTS

Step 1: Setting up Google Colab and Connecting to Google Drive

  1. Open Google Colab: Start by opening Google Colab in your web browser

    .

  2. Create a New Notebook: Create a new Python 3 notebook in Google Colab .
  3. Mount Google Drive: To access your audio files, mount your Google Drive to the Colab environment. This allows you to easily access and store data . To do so is easy, just click on the file icon and click mount drive. After it you will see a folder called drive on the left side of the screen.

Step 2: Preparing Your Audio Sample

To accurately clone a voice, you'll need a high-quality audio sample of the person you want to clone. Here's how to prepare your sample for Coqui TTS:

*   **Record Audio:** Record yourself or another person speaking clearly and naturally. Make sure you record with wav format in 5 to 10 minutes audio time

.

  • Convert to WAV Format: Make sure the audio file is in WAV format. Coqui TTS works with wav files only. If you have an MP3 or M4A, you can use an online converter tool. Also you can adjust the sample rate. Make sure it's 16 KHz.
  • Upload to Google Drive: Upload the audio sample to your Google Drive for easy access from Colab .

Step 3: Installing Coqui TTS and Dependencies

To use Coqui TTS, you'll need to install it and its dependencies in the Colab environment. Follow these steps:

1.  **Open a Code Cell:** Create a new code cell in your Colab notebook

.

  1. Install Coqui TTS: Use the following command to install Coqui TTS:

Step 4: Preparing for a Potential Pandas Version Error and Installing eSpeak

Since there is a high chance that you will encounter a pandas version error, make sure you are using version 2.2.2:

  1. Using Correct Pandas Version: Use the following command to download and use the correct version:
   !pip install --upgrade pandas==2.2.2
  1. Install eSpeak: You will need to install another dependency library called eSpeak with:
 !apt-get install -y espeak

Step 5: Loading the Model and Setting up cloning

Now, load your speaker and the library that you want to clone: 

from TTS.api import TTS

tts = TTS(model_name="tts_models/en/ljSpeech/vits")

Note: If you do not import it, you will face a NameError

Step 6: Performing your Text to Speech and Saving the file

Finally, use tts.tts_to_file to create your audio file:

tts.tts_to_file(text="Hello, in this video we gonna see how to create your own voice using python, an alternative to the eleven labs", file_path="content/drive/MyDrive/AVoice Clone Tutorial/intro.wav")
print ("Voice cloning complete")

Note: Make sure you have the right link
