avoc 0.0.1

Voice changer for desktop

A-Voc Local Realtime Voice Changer for Desktop

A speech-to-speech converter that uses AI models locally to convert microphone audio to a different voice in near-realtime.

Suitable for gaming and streaming.

Quick Start

Features

• Import of the voice models provided by the user
• Switching between voices
• Pitch and volume adjustments
• Hotkeys and popup notifications for the ease of use in the background

Platforms

All desktops.

Linux is the priority.

Goal

Make voice changing more developer-friendly by creating

• a voice conversion library
• a simple voice changer desktop application
• a command-line voice changer program

Open Source and Free for modification.

Installation

With Python Environment

Install:

mkdir avoc-installdir
cd avoc-installdir
pyenv local 3.12.3
python3 -m venv ./venv
pip install avoc

Launch:

python3 -m venv ./venv
avoc

(Optional) Virtual Microphone

To make a game take audio from the voice changer, the operating system needs to be configured to create a virtual microphone.

Linux with PulseAudio

Add this to ~/.config/pulse/default.pa:

load-module module-null-sink sink_name=voice-sink sink_properties=device.description=Voice_Sink
load-module module-remap-source master=voice-sink.monitor source_name=voice-mic source_properties=device.description=Voice_Microphone

And re-login or restart PulseAudio with pulseaudio -k

The Voice_Sink and Voice_Microphone devices will appear. Use the Voice_Sink as voice changer output, and use the Voice_Microphone as input for the game.

Development

Python Environment

Assign a compatible Python version to this directory using pyenv:

pyenv local 3.12.3

Create an environment using venv:

python -m venv .venv

or through VSCode with ~/.pyenv/shims/python as the Python interpreter.

Install the dependencies:

source .venv/bin/activate
pip install .

(Optional) If it doesn't install, try installing reproducible requirements:

pip install -r requirements-3.12.3.txt

Run:

python -m src.avoc.__main__

(Optional) Get sources of the voice conversion library and install it in developer mode:

(cd .. && git clone https://github.com/develOseven/voiceconversion)
source .venv/bin/activate
pip uninstall voiceconversion
pip install -e ../voiceconversion --config-settings editable_mode=strict

It allows to work on the voice conversion library.

(Optional) Add to the "configurations" in the VSCode's launch.json:

{
    "name": "Python Debugger: Module",
    "type": "debugpy",
    "request": "launch",
    "module": "src.avoc.__main__",
}
