Voice-First AI for Field Technicians

For a client in the construction industry, we developed a concept for a mobile AI app that supports field technicians on-site using a single

recording button for questions and reports.

The Challenge

Field technicians document large amounts of information directly on construction sites, at customer locations, or while on the move. Important details can easily be lost or require time-consuming follow-up work at the office. Existing processes are also often paper-based, unstructured, or dependent on manual emails.

The app replaces complex forms with one central button: press briefly to ask a question or press and hold to record a report. AI transcribes the voice input, structures the information, and turns it into clear reports, briefings, or initial cost estimates.

Process

One Button. Two Actions.
Clear Results.

On-Site Assistant

Short Press:
Question. Long Press: Report.

One Button. Two Actions.

1. Short Press – Ask a Question

Voice input
Transcription (Swiss German/German)
Specific answers based on project knowledge

2. Long Press – Record a Report

Observations, progress, materials, issues
AI automatically structures the content
Report, briefing, or cost estimate

3. Skill-Based Processing

Site Assessment
Project Update
Quote / Invoice

4. Output & Storage

Email to the Head Office
Google Drive / Infomaniak
Future: Integration with the OF System

Record On-Site

The technician simply uses their phone and presses briefly for a question or holds the button to record a report — directly on-site.

AI Transcribes

Swiss German and German are reliably converted into text — even in noisy environments.

Structure the Content

Based on the selected skill — site assessment, project update, quote, or invoice — AI creates the appropriate structured document.

Backend Processing

Logs, transcripts, summaries, PDFs, and email statuses are managed centrally.

Keep the Team Informed

Results are automatically sent by email or stored in the relevant project folder.

Key Features

Voice-first app for field technicians

Swiss German and German transcription

Skill-based processing for site assessments, updates, quotes, and invoices

Impact

Turning Voice Input into
Structured Project Work.

Less manual follow-up work in the office

Faster access to information

Reduced workload for project management and administration

Better documentation directly from the construction site

Clear transition from voice input to structured reports

Centralised storage instead of scattered emails and notes

Technical Approach

The app combines a streamlined mobile frontend with an AI-powered backend. Voice input is transcribed, interpreted based on its meaning, and transformed into the required output using predefined skills. The backend logs each process, manages transcripts, and generates PDFs and email status updates.
