Kotoba Plus One — I Did Not Want to Test My Child. I Wanted to Understand Him.
Inspiration
This project began with a very ordinary moment at home.
I said something to my son.
He did not respond in the way I expected.
I tried saying it again. Then I used different words. Then I pointed.
And then I began to wonder whether I was helping him—or simply making the moment harder.
Nothing dramatic had happened.
But inside me, the same questions kept growing:
How much does he understand?
Am I asking too much?
Should I wait longer?
What should I say next?
What can I actually do at home today?
When parents become concerned about their child’s communication, it is easy to start searching for answers everywhere.
We read articles. We compare developmental milestones. We watch every reaction. We ask the same question in different ways, hoping the next response will finally tell us something certain.
But a child is not a test result.
One response does not explain everything.
Silence does not always mean a lack of understanding. A different choice does not always mean the child cannot do something.
Attention, tiredness, familiarity, motivation, timing, and the surrounding environment can all change what we see.
I did not want to turn every interaction with my son into another hidden test.
But I also could not accept doing nothing.
That tension became Kotoba Plus One.
The name “Plus One” does not mean making the child say one more word.
It means helping the parent leave the interaction with:
- one new observation
- one useful insight
- one simple thing to try next
I started building this because I wanted to do something about my own child’s communication.
As I built it, I realized that the first person who needed support was not only my child.
It was me—the parent standing in front of him, unsure what to say next.
What Kotoba Plus One Does
Kotoba Plus One is a mobile-first, daily language-play coach for parents.
A session consists of two to four short picture-card activities and usually takes only a few minutes.
The flow is simple:
- The app presents one original picture-card activity.
- The parent says one short prompt once.
- The parent waits for three to five seconds.
- The child may respond by pointing, looking, gesturing, or speaking.
- The parent records only what was actually observed.
- The app provides one short response the adult can use.
- The session continues with the next activity, or the parent can stop at any time.
For example, the parent may ask:
“Which one is the shoe?”
If the child points to the shoe, the app may suggest:
“You found the shoe.”
The child is not asked to repeat the word.
There is no red cross, correction animation, score, ranking, or “wrong answer” screen.
The purpose is not to force a correct performance.
The purpose is to help the adult notice the child’s response and continue the interaction without pressure.
