[2024] Open Source Voice Changer: Free to Change Your Voice

By Ivan Davis · Published on May 16, 2024

Have you ever wanted to sound like a deep-voiced villain, a helium-filled chipmunk, or anything in between? Maybe you desire more privacy online or just want to have some fun during your next gaming session. This article is for you! We understand the desire to alter your voice, and while there are paid options available, there are also fantastic free, open-source solutions. GitHub is the number one source for open-source projects with a big community. This article will cover open-source voice changers, specifically the top four options found on GitHub.

What is Open Source Voice Changer?

Open-source voice changers are free software programs that let you alter your voice in real-time. Unlike paid options, the code is publicly available, allowing for customization and community-driven development. This openness allows users and developers to examine, modify, and enhance the software according to their needs. While they may offer fewer effects than commercial programs, they’re great for basic voice modification during calls, gaming, or creative projects.

4 Excellent Open Source Voice Changers From GitHub

GitHub hosts the majority of open-source projects, making it a centralized hub for finding high-quality, freely accessible software. These projects are typically well-documented, regularly updated, and benefit from community contributions and peer reviews. Users can freely modify and adapt the code to suit their specific needs, fostering innovation and customization. Moreover, the collaborative nature of GitHub ensures a supportive environment where users can seek assistance, report issues, and contribute to the project’s development.

1. SoftVC VITS Singing Voice Conversion

Project Stars: 24.2k+🌟

Project Address: https://github.com/svc-develop-team/so-vits-svc?tab=readme-ov-file

SoftVC VITS Singing Voice Conversion is a tool that lets you alter the voice in a singing performance. It works by taking a recording of someone singing and using that audio to create a new singing voice that retains the original singer’s pitch and intonations. This is achieved by analyzing the audio with a “content encoder” which extracts key characteristics and then feeds that information into a model alongside the desired target voice.

The result is a new singing voice that sounds like the target singer but still carries the melody and phrasing of the original performance. The developers insist that Text to Speech (TTS) feature is not supported in this program and differs greatly from Singing Voice Conversion (SVS). They also insist that the program is designed to help developers create music from anime characters and not real individuals.

2. Lyredbird

Project Stars: 1.8k+🌟

Project Address: https://github.com/lyrebird-voice-changer/lyrebird

This is a Linux program that can modify your voice in real time. It offers built-in effects for male and female voices, along with custom presets and pitch adjustments. With Lyrebird users can easily load or create custom presets. Additionally, this program comes with a manual pitch which lets you customize the voice further untill you get a finer adjustment. However, development stopped in December 2023, so it’s no longer actively supported. You can still use it but do so with caution incase of any bugs that have not been fixed. Since the developers have abandoned the project only the community can help you if you run into issues.

3. Figaro

Project Stars: 756🌟

Project Address: https://github.com/MattMoony/figaro

This is a free and open-source program for Windows, Mac, and Linux. As a compatible platform with these three top operating systems, it ensures accessibility for many users. It offers real-time voice modification and a soundboard function. You can use it to apply various effects to your voice during calls, recordings, or even while streaming. The Figaro soundboard contains several varieties of sound effects. You can set keyboard shortcuts for the effects alongside comments to help you remember in the future what they are about. This program comes with a simple but sleek user interface making it suitable for both novice and professional users.


Project Stars: 703🌟

Project Address: https://github.com/Tiger14n/RVC-GUI

RVC-GUI stands for Retrieval-Based Voice Conversion Graphical User Interface. It’s a free, open-source program that lets you modify your voice in real time using artificial intelligence (AI). RVC-GUI utilizes pre-trained AI models to transform your voice into another voice. These models are trained on recordings of different speakers, allowing you to mimic their characteristics like pitch, tone, and even some stylistic elements. It doesn’t limit you to one voice.

You can choose from various pre-trained models, potentially including ones that mimic specific characters or voice types. The program boasts a user-friendly GUI that allows you to manage settings like microphone and speaker selection, choose the desired voice model, and initiate the voice conversion process.
