D-0004 Our smoke alarm rings with a nice voice

This was compiled from household notes kept in a condominium unit in Matsudo. The writer was a housewife who made a habit of pressing the test button of the residential smoke alarm on the first of every month, and a single line confirming the battery continues in the same form for several years. The change begins in the spring of 2025. A line appears saying that the way the “Normal” announcement trails off resembles her husband’s absent replies, and beneath it remains a note in which she cancels the thought herself: it only sounds similar because I think it does.

The next month’s notes mention the pause for breath; the month after that, the pitch. The progression was not steady — there were reportedly months it skipped, and months it seemed to have gone back. On the same pages, on lines separate from the test records, she writes that her husband had come to only nod at the dinner table, and that he no longer laughed at the television. The writer does not connect the two anywhere. There is also a note that outside the home he was unchanged, and that his voice was lively on calls from his office.

Recording was attempted. She recorded the test voice on the telephone to play to her mother, but the recording reportedly held only the standard machine voice. She also asked her husband, once. When she said, it’s starting to sound like your voice, he was quiet for a moment and answered only: is it. That night’s note reads, one more reply inside this house is gone.

Around the turn of the year, the husband replaced the unit itself with a new one. At the first test out of the box, the new device reportedly sounded with the same habits partway through. No individual variation exists in the voice — that was the answer from the manufacturer’s desk. After that, this household stopped pressing the test button. But in spring came the statutory fire-equipment inspection, and a contractor went from unit to unit pressing every button in turn. It is recorded that the contractor, up on the stepladder, remarked: it rings with a nice voice. The writer notes only that she laughed and let it pass.

Within that week, it is said, the alarm sounded once — “Normal” — in the middle of the night, with no one pressing it. The writer heard it standing under the ceiling, in the corridor on her way back from the bathroom. Her husband, in the bedroom, did not wake. An inquiry reached the manufacturer’s desk the next day, and the reply preserved among her papers states that the model in question has no self-test function that sounds on its own.

One reading remains from the cross-check: that the device on the ceiling, after years of picking up the sounds of the life beneath it, has come to answer in the voice it heard most often. There is also a line of the writer’s own, that the voice seems to grow more similar each time she presses the button to check; which comes first, the checking or the changing, has not been determined.

On the page for May there is an entry saying the voice had returned to the standard machine voice. The writer pressed the button three more times on the spot. All three times, it was no one’s voice. The note says only: it has gone back. There is no sign that her husband began to speak inside the home that month. On the first of the following month, the alarm reportedly rang in his voice again.

The notes are said to continue even now, once a month. The writer can no longer remember when her husband last spoke inside the house. Still, on the first of every month, she presses the button. On the last page, a single line gives the reason. If I stop, I feel there will be nowhere left in this house to hear his voice.
