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.
