Voice Changer Android App

After talking about voice changers for Windows, let's talk about some of the best tools you can use for Android today, or in other words, open-source voice changer apps for Android. Now, you don't have to go to Google Play to find any of them, as we have compiled a list of two right here:

1. Voice Changer with Effects

Voice Changer with Effects is one of the leading tools on Android for changing voices. As a call voice changer, this app is not only easy to use but also offers a few hilarious voice effects, which is why it has been around for years.

Besides that, it's open source, so you can tweak it around all you like. Or, you can simply use one of the four filters, which includes aliens and zombies, to do a funny voice recording. That's what makes this the most famous voice changer on Android today.

  • Various fun-inducing voice filters
  • Very easy to use
  • Ideal for beginners


  • Doesn't support live-voice morphing
  • The design is obsolete

2. Voice Changer - Audio Effects

Voice Changer - Audio Effects is a wonderful app. And as the name suggests, it allows you to change your voice during voice recording or change the background with sound effects. While it's ideal for voice recording only, it can also help you convert existing audio clips.

Therefore, this open-source tool isn't just for those who wish to record their voice in a different filter. It's also ideal for those who wish to convert their existing call or other audio recordings using funny and customizable voice effects.

Open Source Voice Changer FAQs

Any of your further questions will be answered in this section:

1. What is the best completely free voice changer?

The best kind of voice changer is Voicemod, although it's not completely free. It allows you to do many things with the tool before you reach the free limit. On the other hand, you have Clownfish, which is totally free but doesn't have customization or filters like Voicemod.

2. Are voice changers illegal?

No, it's not. Unless a person changes their voice for fraudulent or illegal activities, it is not illegal or banned in any country. However, you should be careful as some people might use a voice changer to scam you.

3. What is better than Voicemod?

There are a few alternatives to Voicemod, but you can't call them better than Voicemod. The primary reason behind that is the ability of Voicemod isn't exactly dependent on its voice filters but also on customizability and user-friendliness.


These are some of the best open-source voice filters and changes that you can use in 2024. We explored a few great options, and perhaps Equalizer APO is the best open-source tool. However, it doesn't offer the same features as Voicemod or MorphVox Pro.

Then again, it dials down to the need of the users and how much they wish to use this voice changer. If you're a casual user or gamer, then using Voicemod is ideal. But, if you wish to go technical, then Equalizer APO is a good option.
