How to Install NVIDIA Parakeet TDT 0.6B V2 Locally?

Parakeet-TDT 0.6B V2 is a high-performance speech-to-text model developed by NVIDIA for English audio transcription. Built on the FastConformer architecture with a TDT decoder, it’s designed to handle long-form speech (up to 24 minutes) while preserving punctuation, capitalization, and accurate word-level timestamps. Whether you’re transcribing conversations, meetings, or spoken content with background noise, this model delivers fast and reliable results — making it a powerful tool for developers, researchers, and transcription workflows. It supports .wav and .flac formats and is fully optimized for GPU acceleration.

Minimum (Lightweight) Setup for Inference Only:

  • GPU: NVIDIA T4 (16 GB VRAM)
  • vCPUs: 8+
  • RAM: 16 GB
  • Disk: 30–40 GB
  • Works for shorter audio (<10 mins) and lower concurrency

Tested GPU Models:

  • A6000 (what you’re currently using — excellent)
  • A100, H100 (overkill, blazing fast)
  • L4, T4 (okay for smaller inference jobs)
  • CPU-only: Not recommended due to heavy inference load and slow RTFx.

Step-by-Step Process to Install NVIDIA Parakeet TDT 0.6B V2 Locally

For the purpose of this tutorial, we will use a GPU-powered Virtual Machine offered by NodeShift; however, you can replicate the same steps with any other cloud provider of your choice. NodeShift provides the most affordable Virtual Machines at a scale that meets GDPR, SOC2, and ISO27001 requirements.

Step 1: Sign Up and Set Up a NodeShift Cloud Account

Visit the NodeShift Platform and create an account. Once you’ve signed up, log into your account.

Follow the account setup process and provide the necessary details and information.

Step 2: Create a GPU Node (Virtual Machine)

GPU Nodes are NodeShift’s GPU Virtual Machines, on-demand resources equipped with diverse GPUs ranging from H100s to A100s. These GPU-powered VMs provide enhanced environmental control, allowing configuration adjustments for GPUs, CPUs, RAM, and Storage based on specific requirements.

Navigate to the menu on the left side. Select the GPU Nodes option, create a GPU Node in the Dashboard, click the Create GPU Node button, and create your first Virtual Machine deploy

Step 3: Select a Model, Region, and Storage

In the “GPU Nodes” tab, select a GPU Model and Storage according to your needs and the geographical region where you want to launch your model.

Image description

We will use 1 x RTX A6000 GPU for this tutorial to achieve the fastest performance. However, you can choose a more affordable GPU with less VRAM if that better suits your requirements.

Step 4: Select Authentication Method

There are two authentication methods available: Password and SSH Key. SSH keys are a more secure option. To create them, please refer to our official documentation.
Image description

Step 5: Choose an Image

Next, you will need to choose an image for your Virtual Machine. We will deploy NVIDIA Parakeet TDT on an NVIDIA Cuda Virtual Machine. This proprietary, closed-source parallel computing platform will allow you to install NVIDIA Parakeet TDT on your GPU Node.
Image description

After choosing the image, click the ‘Create’ button, and your Virtual Machine will be deployed.
Image description

Step 6: Virtual Machine Successfully Deployed

You will get visual confirmation that your node is up and running.
Image description

Step 7: Connect to GPUs using SSH

NodeShift GPUs can be connected to and controlled through a terminal using the SSH key provided during GPU creation.

Once your GPU Node deployment is successfully created and has reached the ‘RUNNING’ status, you can navigate to the page of your GPU Deployment Instance. Then, click the ‘Connect’ button in the top right corner.

Image description

Now open your terminal and paste the proxy SSH IP or direct SSH IP.
Image description

Next, if you want to check the GPU details, run the command below:
nvidia-smi

Image description

Step 8: Check the Available Python version and Install the new version

Run the following commands to check the available Python version.

If you check the version of the python, system has Python 3.8.1 available by default. To install a higher version of Python, you’ll need to use the deadsnakes PPA.

Run the following commands to add the deadsnakes PPA:
sudo apt update
sudo apt install -y software-properties-common
sudo add-apt-repository -y ppa:deadsnakes/ppa
sudo apt update

Image description

Step 9: Install Python 3.11

Now, run the following command to install Python 3.11 or another desired version:
sudo apt install -y python3.11 python3.11-distutils python3.11-venv

Image description

Step 10: Update the Default Python3 Version

Now, run the following command to link the new Python version as the default python3:
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.11 2
sudo update-alternatives --config python3

Then, run the following command to verify that the new Python version is active:
python3 --version

Image description

Step 11: Install and Update Pip

Run the following command to install and update the pip:
python3 -m ensurepip --upgrade
python3 -m pip install --upgrade pip

Then, run the following command to check the version of pip:

import nemo.collections.asr as nemo_asr

# Load model once
asr_model = nemo_asr.models.ASRModel.from_pretrained(model_name="nvidia/parakeet-tdt-0.6b-v2")

def transcribe_audio(audio, timestamps=False):
    if audio is None:
        return "Please upload a valid audio file."

    output = asr_model.transcribe([audio], timestamps=timestamps)

    if timestamps:
        segments = output[0].timestamp['segment']
        result = ""
        for seg in segments:
            result += f"{seg['start']}s - {seg['end']}s: {seg['segment']}\n"
        return result
    else:
        return output[0].text
