How to create estimates by voice | Draft done in 30 seconds on site with AI

Published: 2026-07-21 / Author: Akio Nojima (handyman & well driller / owner of Nojima Giken)
Creating estimates by voice input means just saying to your smartphone, "Estimate for Mr. Tanaka: cutting down one garden tree, ¥15,000, and disposal fee ¥8,000," and having AI generate a draft estimate automatically. Even with field work that gets your hands dirty, the paperwork is done in the car on the way home (while parked) or during a break.

How creating an estimate by voice works

  1. Open your business management software on your smartphone and press the voice input button
  2. Speak naturally: "For Mr./Ms. ○○, △△ work for □□ yen"
  3. AI recognizes the customer name, items, quantities and amounts and generates a draft estimate
  4. Check the content and make small fixes → save and send

On actual job sites, one estimate is finished in about 30 seconds of talking + 1 minute of checking. Compared with 15 minutes in Excel, that saves about 4.5 hours a month with 20 estimates.

FAQ

Q. Are voice-input estimates accurate?A. Recognition of customer names, items and amounts is highly accurate, but a person always does the final check. It is most accurate to think of it as "automatic draft generation"; even with the check, it is done in a fifth of the time or less compared with before.
Q. Can I use voice input while driving?A. No. Always operate it while parked. We recommend using it in a parking lot or rest area, not while waiting at a light.
Q. Does it recognize dialects and technical terms?A. The latest AI speech recognition handles dialects quite well, but industry-specific abbreviations can be misrecognized. Registering frequently used items in the software's item master makes it reliable.
