How to use resonero

Set it up once. Then just talk.

1. Place the processor near the conversation
Connect it to the included speaker, then plug it into USB-C power.

2. Position the speaker nearby
Place it three to six feet from the processor on a shelf, table, or floor.

3. Set the volume once
Adjust the level until the added sound blends naturally into the room.

Then leave it on. Resonero stays ready in the background.

How it works

The meaning is in the melody

Every voice carries more than words. Its intonation helps communicate how speakers feel and what they mean: serious or joking, worried or reassured, frustrated or patient.

  •  1. The lowest pitch carries emotion and meaning 

    The rise and fall of a voice’s fundamental pitch—the lowest frequency produced by the vocal cords—forms its intonation melody. These changes help convey emotion, emphasis, and intent.

  •  2. Some people misperceive the fundamental pitch  

    In conversation, the lowest frequencies can be hard for some people to recognize in what others say and in their own voice.  This contributes to misunderstanding and unintended conflict.

  •  3. Resonero subtly reinforces the melody of meaning 

    Resonero gently amplifies the fundamental pitch of speech, blending the added sound into the room. It’s designed to help speakers and listeners perceive the feeling and emphasis behind the words, so the intended meaning comes through more naturally.

Frequently Asked Questions

What does Resonero do?

Resonero improves conversations and reduces misunderstandings by subtly changing the acoustics in a room. The Resonero device is a tiny two-inch square box containing a custom Intonation Processor that connects to a
small speaker. 

It amplifies the intonation melody of all the conversations in the room, providing subtle cues to help speakers and listeners communicate the meaning and intent behind the words spoken.

How does changing the room acoustics reduce misunderstanding?

When we talk, our meaning isn’t just what we say but how we say it. Our intonation—the rise and fall of our voice’s pitch—conveys a lot of information about what we mean and how we feel. 

Some people have a harder time perceiving and interpreting this vocal melody. They are more likely to misread how someone feels or what they intend. And it’s more difficult for them to hear how their own tone is coming across.

With Resonero in the room, more of the pitch information in speech is available to hear. That can give you better feedback about your own volume and intonation, making it easier to adjust how you sound without consciously thinking about it. And it can help you see the feelings behind the words that others are saying.

Will other people in the room notice it?

Probably not. The Resonero Intonation Processor and speaker are small and can be set up on any convenient table or shelf. Neither has any lights or other features that attract attention.

The sound is set at a low level so that the added pitch information is not noticeable. Many early users describe the effect simply as making the room sound warmer. 

How do I know whether Resonero might help me?

Resonero may be worth trying if you often feel that your tone is misunderstood, other people’s intentions are hard to read, conversations take more effort than they seem to for others, or recordings of your voice don’t sound the way you expect. 

If those experiences sound familiar, the best way to find out whether Resonero helps is to try it in your normal conversations and see whether communication feels easier and clearer.

How long does it take for Resonero to work?

Some people notice a change in the first conversation they have with Resonero. For others, the effect builds over several weeks. Sometimes people around them notice a change before they do.

Experiences vary, which is why we encourage people to use Resonero in their normal conversations for a while before deciding whether it is helping.

What happens if I try it and it does not help me?

If you are not sure that Resonero is helping you, reach out to us and we’ll make sure that you’ve got the device positioned and set for maximum benefit. If you decide it’s not for you, you can return it for a full refund within 30 days.

Are my conversations private?

Absolutely. Resonero doesn’t store or transmit your conversations or any data about you. All the sound processing is done on the device.  Resonero has no Wi-Fi, Bluetooth, or Internet connection. For more information, see our privacy policy.
