Introducing KKEBI: Voice-Based Mind Care for Employees

Here is KKEBI in one sentence. A voice-based mind care service in which employees reflect on their own state through a short voice check-in, and an AI tracks that change alongside them.

We are not trying to rank people by score or to surveil them. We start from the fact that neither burnout nor attrition is decided suddenly, one day. Change begins little by little before that, and if we can notice that change a bit earlier, both the individual and the organization gain more options.

01. The problem KKEBI solves

It is only after an important employee decides to leave that the organization begins to look for reasons. Was the workload too heavy? Was the compensation lacking? Were relationships the problem? But human experience is never that sudden.

Before that, changes such as “I feel no sense of accomplishment lately,” “resting on weekends no longer restores me,” and “just going to work feels like a burden” quietly accumulate. The problem is that the moment an organization recognizes that change is usually far too late — because declining performance or a stated intent to resign are signals that appear only after things have already progressed considerably.

We covered the background of this problem in more detail in Early Detection of Employee Burnout.

02. A short voice check-in

KKEBI’s starting point is a short voice check-in. Long surveys and periodic interviews carry a heavy burden and are hard to do often. And if you cannot do it often, you cannot see change.

So KKEBI chose the form of a short voice conversation that employees can join often, without pressure. From the employee’s perspective, this time is not a time to report to the company but a time to reflect on your own state for yourself. It is a brief moment to consider how your condition is today, what is weighing on you, and how the you of these days differs from the you of a while ago.

03. We look at change, not absolute scores

KKEBI’s core design principle is to look at change relative to a personal baseline rather than absolute scores.

Everyone has a different usual speaking pace, mode of expression, and rhythm of condition. It makes no sense to apply the same standard to someone who naturally speaks fast and someone who speaks slowly. So instead of holding one yardstick up to everyone, KKEBI takes each person’s usual state as the baseline and observes “what is changing, and in which direction.”

Doing so lets us focus not on a stigmatizing question like “is this person normal or not,” but on the question “how has the me of these days changed from my usual self.” This is closer to self-understanding than to evaluation.

04. Voice is a supporting signal

A voice carries not only the content of what is said but also the way it is said. Elements such as pitch, pace, pauses, and voice quality can be connected to a person’s state. KKEBI uses these voice signals as clues for understanding individual change.

But one thing must be made clear. Voice is not the sole judge but a supporting signal. We do not conclude a person’s state of mind from voice alone. We place several signals together — voice, language, check-ins — and read change carefully against the person’s usual state.

How voice signals can be seen as clues to a state, and the principle behind it, are laid out in The Complete Guide to Voice Biomarkers.

05. Trust comes first — who sees what

In employee mental health technology, what matters as much as accuracy is who can see what. If a company were to peer at individual-level data, no one would honestly reveal themselves. And then this tool could not work from the very start.

So KKEBI is designed this way.

• To individuals, it provides an understanding of their own state and change.
• To the organization, it provides only group-level trends and risk factors that cannot identify a specific person — never the content of individual sessions.

In other words, the organization can reference “which direction the flow of our team/organization is heading right now,” but it cannot see “who said what.” This boundary is the pillar that upholds KKEBI’s trust.

06. What KKEBI aims for

What KKEBI wants to build is not a tool for analyzing the causes after a person has broken down. It is helping people notice change before they break down, while there are still options left.

Giving individuals an occasion for self-understanding, and giving the organization a reference point for observing the flow without identifying any specific person. On that balance, KKEBI builds voice-based mind care for employees.
