Installing Tacotron2

Now that we have our prerequisites sorted out, let’s jump into the installation process of Tacotron2 in Visual Studio Code.

Step 1: Clone the Tacotron2 Repository

The first step is to clone the Tacotron2 repository from its GitHub repository. Open Visual Studio Code and follow these instructions:

  1. Open the integrated terminal in Visual Studio Code by navigating to View > Terminal or using the shortcut `Ctrl + “.
  2. Navigate to the directory where you want to store the Tacotron2 project.
  3. Run the following command to clone the repository:
git clone

Step 2: Set Up Virtual Environment

To manage the dependencies of Tacotron2 and ensure a clean installation, let’s create a virtual environment. In the terminal, execute the following commands:

cd tacotron2
python3 -m venv venv
source venv/bin/activate

Step 3: Install Dependencies

With the virtual environment activated, it’s time to install the required dependencies. These dependencies include PyTorch, NVIDIA Apex, and other essential libraries. Run the following commands one by one:

pip install numpy
pip install torch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 -f
git clone
cd apex
pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./
cd ..
pip install unidecode
pip install pillow
pip install scipy
pip install librosa
pip install inflect

Step 4: Download Pre-Trained Models and Data

Tacotron2 requires pre-trained models and data to function effectively. Download the models and data using the following commands:

mkdir -p ~/.cache/tacotron2
cd ~/.cache/tacotron2
tar xvf LJSpeech-1.1.tar.bz2

Step 5: Configuration

Next, we need to configure Tacotron2’s hyperparameters. In the tacotron2 directory, locate the file and modify the parameters according to your preferences. This step allows you to fine-tune the synthesis process based on your specific requirements.

Running Tacotron2

With Tacotron2 successfully installed and configured, it’s time to put it to work and generate some mesmerizing speech synthesis. Follow these steps to run Tacotron2:

Step 1: Prepare Text Input

Create a text file containing the text you want Tacotron2 to synthesize. Make sure the text is clear, concise, and accurately represents the desired speech output.

Step 2: Synthesize Speech

In the terminal, navigate to the tacotron2 directory and run the following command:

python --text_list /path/to/your/text/file.txt --output_dir /path/to/save/output

Replace /path/to/your/text/file.txt with the actual path to your text file and /path/to/save/output with the desired directory to save the synthesized speech.

Troubleshooting Tacotron 2 Installation

Installing and setting up Tacotron 2 for text-to-speech synthesis can sometimes be a complex process, and you might encounter a few bumps along the way. Don’t worry, though – we’re here to help you troubleshoot and overcome common issues that can arise during the installation process. In this guide, we’ll address potential problems and provide solutions to ensure a smooth experience with Tacotron 2.

Issue 1: Python Version Compatibility

Problem: Tacotron 2 relies on specific Python packages and dependencies. If you encounter compatibility issues with your Python version, the installation process might fail.

Solution: Ensure that you’re using a compatible Python version (preferably 3.6 or later) and have set up a virtual environment to isolate the installation. You can create a virtual environment using the following commands:

bashCopy codepython3 -m venv venv
source venv/bin/activate

Issue 2: PyTorch Installation

Problem: PyTorch is a critical dependency for Tacotron 2, and an incorrect installation or version mismatch can lead to errors.

Solution: Install PyTorch and other necessary packages using the specified versions and installation instructions in the Tacotron 2 guide. Make sure to follow the exact commands to install PyTorch with the correct CUDA version if you’re using a GPU.

Issue 3: NVIDIA Apex Installation

Problem: NVIDIA Apex is a library that Tacotron 2 utilizes for mixed-precision training. If the installation of Apex fails, it can disrupt the overall installation process.

Solution: Follow the Apex installation instructions carefully. Ensure you have the required dependencies, and try installing Apex with the provided commands. If you encounter issues, check the GitHub repository for any reported problems or workarounds.

Issue 4: Data and Model Download

Problem: Tacotron 2 requires pre-trained models and data for synthesis. If the data and models are not downloaded or placed in the correct directory, Tacotron 2 won’t function properly.

Solution: Double-check that you’ve downloaded the required pre-trained models and data and placed them in the designated directories as instructed. Verify the file paths and make sure they match the paths specified in the Tacotron 2 configuration.

Issue 5: Hyperparameter Configuration

Problem: Incorrect hyperparameter settings can lead to suboptimal or erroneous synthesis results.

Solution: Review and adjust the hyperparameter settings in the file carefully. Make sure the parameters are appropriate for your use case and hardware. Experiment with different settings to achieve the desired speech synthesis output.

Issue 6: Synthesis Failure

Problem: If Tacotron 2 fails to synthesize speech or produces unsatisfactory results, there may be issues with the input text, configuration, or hardware settings.

Solution: Check the input text for clarity and correctness. Review the configuration settings and ensure that you’re using compatible hardware. Experiment with different texts and hyperparameter configurations to improve synthesis quality.

Issue 7: System Dependencies

Problem: Tacotron 2 might rely on system-level dependencies that are missing or incompatible on your system.

Solution: Ensure that you have all the required system dependencies installed, such as CUDA drivers and audio libraries. Refer to the Tacotron 2 documentation for a list of dependencies and installation instructions.

Issue 8: Environment Activation

Problem: If you’re encountering errors related to environment activation or package paths, it could be due to incorrect virtual environment setup.

Solution: Make sure you’re using the correct virtual environment by activating it with the source venv/bin/activate command. Verify that the necessary packages are being imported from within the virtual environment.


Congratulations! You’ve successfully embarked on a journey into the realm of text-to-speech synthesis with Tacotron2. In this guide, we covered the installation process step by step, from cloning the repository to configuring hyperparameters and generating speech. With Tacotron2 at your fingertips, you now have the power to create natural-sounding and expressive speech synthesis, opening up a world of possibilities in voice-driven applications, audio production, and beyond.
