Introduction

Realtime voice cloning is a fascinating application of deep learning and natural language processing (NLP) that enables the creation of high-quality voice clones in real-time. With the advancement of technologies like WebSocket, it is now possible to achieve <1 second latency in voice cloning applications. In this article, we will explore the possibility of performing Realtime voice cloning using the server.py and client.py files in the WebSocket repository.

Understanding Realtime Voice Cloning

Realtime voice cloning involves the creation of a voice clone that can mimic the voice of a target speaker in real-time. This is achieved by using a deep learning model that can learn the acoustic characteristics of the target speaker's voice and generate a new audio signal that sounds like the target speaker. The key challenge in real-time voice cloning is to achieve low latency, which is the time it takes for the voice clone to respond to the input audio signal.

WebSocket and Realtime Voice Cloning

WebSocket is a protocol that enables bidirectional, real-time communication between a client and a server over the web. It is designed to provide low-latency communication, making it an ideal choice for real-time voice cloning applications. The WebSocket protocol allows for the establishment of a persistent connection between the client and server, enabling the exchange of data in real-time.

Server.py and Client.py Files

The server.py and client.py files in the WebSocket repository provide a basic implementation of a WebSocket server and client, respectively. These files can be used as a starting point for building a real-time voice cloning application. The server.py file sets up a WebSocket server that listens for incoming connections, while the client.py file establishes a connection to the server and sends and receives data in real-time.

Performing Realtime Voice Cloning with WebSocket

To perform real-time voice cloning using the server.py and client.py files, we need to modify the code to include a deep learning model that can learn the acoustic characteristics of the target speaker's voice and generate a new audio signal that sounds like the target speaker. We can use a library like TensorFlow or PyTorch to implement the deep learning model.

Here is an example of how we can modify the server.py file to include a deep learning model for real-time voice cloning:

import socket
import json
import numpy as np
from tensorflow.keras.models import load_model

# Load the deep learning model
model = load_model('voice_clone_model.h5')

# Set up the WebSocket server
ws = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ws.bind(('localhost', 8080))
ws.listen(1)

while True:
    # Accept incoming connections
    conn, addr = ws.accept()
    print('Connected to', addr)

    # Receive audio data from the client
    audio_data = conn.recv(1024)
    print('Received audio data')

    # Preprocess the audio data
    audio_data = np.frombuffer(audio_data, dtype=np.float32)
    audio_data = audio_data.reshape(-1, 1)

    # Use the deep learning model to generate a new audio signal
    output = model.predict(audio_data)

    # Send the output signal to the client
    conn.sendall(output.tobytes())
    print('Sent output audio signal')

    # Close the connection
    conn.close()

And here is an example of how we can modify the client.py file to send and receive audio data in real-time:

import socket
import json
import numpy as np

# Set up the WebSocket client
ws = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ws.connect(('localhost', 8080))

while True:
    # Send audio data to the server
    audio_data = np.random.rand(1024).astype(np.float32)
    ws.sendall(audio_data.tobytes())
    print('Sent audio data')

    # Receive output audio signal from the server
    output = ws.recv(1024)
    print('Received output audio signal')

    # Play the output audio signal
    import pyaudio
    p = pyaudio.PyAudio()
    stream = p.open(format=pyaudio.paFloat32, channels=1, rate=44100, output=True)
    stream.write(output)
    stream.stop_stream()
    stream.close()
    p.terminate()
