Do you like the way your own voice sounds? A lot of people would say no, absolutely not. Luckily, we live in an age where custom voice changers and AI voices are a real thing.

Today, voice modulators can change your voice in real time, so you can sound entirely different to those listening to you as you speak.

Content creators, for example, use voice changers to engage their audience and deliver more dynamic content. However, you don’t have to stream Fortnite or any online game on Twitch for a living or be a social media influencer to have fun with voice changers!

How does voice simulation work?

Most voice changers transform pitch-sensitive fundamental waves of the user’s voice. Voice pitch is, in a way, our voice’s DNA, but not all voice changers can do a flawless job and may deliver an overly robot-like sound.

Now, while you have physical instruments to change voice, digital ones offer more and better options. Actually, some of the voices you’ve heard on the internet and thought were human could easily be just AI voices.

Sound effects can slightly change your natural voice, but there are voice effects that can turn you into a completely different person with a completely different voice! Voice filters can make you sound like a cute animal, robot, older, or your younger self — the possibilities are endless!

What languages can voice simulators do?

English is by far the most common language for voiceovers. Some languages like Spanish and French are spoken in many countries and are, therefore, more easily found in the world of voice changers.

For example, Speechify offers Spanish, French, Chinese, Portuguese, Dutch, Hindi, Arabic, Japanese, German, Italian, Hebrew, and Russian as options for high-quality voiceovers.

Representation matters and diversity is important, so it’s always great to see voice simulators, including different languages and dialects.

Speechify Voice Changer

The voice changer in Speechify Studio empowers users to alter recorded speech into a new voice from a library of 1,000+ lifelike AI voice options—without losing the emotion, rhythm, or intent behind the original words. Whether you’re narrating a book, localizing content, or building multi-character dialogue for animation, this voice changer ensures your audience hears compelling, natural performances that go far beyond regular text to speech.
