    Free Real-Time Audio AI Model: Introducing Ultravox

    In the world of Artificial Intelligence, the ability to process and understand audio in real-time has opened up incredible possibilities. Imagine having an AI that can not only listen but also comprehend and respond to spoken words instantaneously. Today, we’re diving deep into Ultravox, a cutting-edge free real-time Audio AI Model that brings this vision to life. Built upon the robust Llama3.1-8B-Instruct and whisper-large-v3-turbo backbones, Ultravox stands as a powerful tool for real-time audio analysis and interaction.

    What Makes Ultravox a Game Changer, for free real-time Audio AI Model?

    Ultravox isn’t just another audio processing tool; it’s a multimodal speech Large Language Model (LLM) that can interpret both text and speech inputs. This means you can give it a text prompt and then follow up with a spoken message. The model processes this input in real-time, replacing a special <|audio|> token with embeddings derived from your audio input. The beauty of this approach is that it allows the model to act as a dynamic voice agent, capable of handling speech-to-speech translation, analyzing spoken content, and much more.

    How Does Ultravox Work?

    The magic behind Ultravox is its ingenious combination of pre-trained models. It utilizes Llama3.1-8B-Instruct for the language processing backbone and whisper-large-v3-turbo for the audio encoder. The system is designed so that only the multimodal adapter is trained, while the Whisper encoder and Llama remain frozen. This approach makes it efficient and effective. The model undergoes a knowledge-distillation process, aligning its outputs with those of the text-based Llama backbone. It is trained on a diverse mix of datasets, including ASR and speech translation data, enhanced by generated continuations from Llama 3.1 8B.

    Ultravox Tutorial: Setup and Install Ultravox Locally

    To get your hands on this free real-time Audio AI Model, you need to follow these simple steps:

    1. Installation: Start by installing the necessary libraries using pip:

    pip install transformers peft librosa

    2. Import Libraries: Import the libraries and load the model pipeline:

    import transformers
import numpy as np
import librosa

pipe = transformers.pipeline(model='fixie-ai/ultravox-v0_4_1-llama-3_1-8b', trust_remote_code=True)

    3. Load Audio: Load your audio file, ensuring a 16000 sample rate:

    path = "<path-to-input-audio>"  # Replace with your audio file path
audio, sr = librosa.load(path, sr=16000)

    4. Prepare the turns:

      turns = [
   {
     "role": "system",
     "content": "You are a friendly and helpful character. You love to answer questions for people."
   },
 ]

    5. Run the Model: Run the model by providing the audio, the turns and sampling rate:

    pipe({'audio': audio, 'turns': turns, 'sampling_rate': sr}, max_new_tokens=30)

    The Complete code to run the Ultravox is:

    # pip install transformers peft librosa

import transformers
import numpy as np
import librosa

pipe = transformers.pipeline(model='fixie-ai/ultravox-v0_4_1-llama-3_1-8b', trust_remote_code=True)

path = "<path-to-input-audio>"  # TODO: pass the audio here
audio, sr = librosa.load(path, sr=16000)


turns = [
  {
    "role": "system",
    "content": "You are a friendly and helpful character. You love to answer questions for people."
  },
]
pipe({'audio': audio, 'turns': turns, 'sampling_rate': sr}, max_new_tokens=30)

    Ultravox is a significant leap forward in the field of real-time audio AI.
