Field Service Voice Capture Hardware
Custom voice capture devices for field-service software companies, service networks and the contractors they equip.
Field-service platforms run scheduling, dispatch and invoicing. What they rarely capture is what the technician saw, measured and told the customer on site — because that depends on someone typing it in after the job. A dedicated voice capture device closes that gap: the technician speaks while working, and the record lands in your platform through an SDK or API. GMIC designs and manufactures these devices under your brand, from proof of concept to volume production.
Why does field service software need its own capture hardware?
The most valuable information in a service visit is spoken: the noise the system made, the reading at the gauge, what the homeowner said about the last repair, why the technician recommended a replacement. It is also the most perishable. By the end of a ten-hour day, much of it is gone or compressed into a few words in a notes field.
Phones help, but only when a technician stops working to use one. A device built for the job captures the record at the moment it happens, with the job context attached, and hands it to your software instead of a consumer app.
The device does not replace your field-service platform. It is the input layer your platform has been missing.
Which kinds of vendors make field service voice capture hardware?
| Category | Examples | Strong at | Limits for field service |
|---|---|---|---|
| Rugged wearables and headsets | Zebra, Honeywell | Voice-directed work in warehouses and logistics, enterprise device management | Built around their own platforms and long voice-directed shifts, not short service visits |
| Consumer AI recorders | Clip-on and card-style note takers | Meetings and personal notes, polished apps | Data and app belong to the recorder vendor; not managed as a fleet; not your brand |
| Body-worn cameras | Security and inspection cameras | Visual evidence | Heavier, video-first, and raise more privacy questions than voice |
| Custom voice capture devices (ODM / OEM) | GMIC and other hardware ODMs | Your brand, your app, your cloud; designed around your workflow | Requires a volume commitment and a development schedule |
If you need one device for a handful of technicians, buy off the shelf. If you are a software company or a service network that wants the capture moment inside your own product, build.
How does a field voice device connect to your platform?
1. Capture on the device
One press or tap starts a note. Audio is buffered on the device, so basements and crawlspaces without signal are not a problem.
2. Transfer through your app or directly
Bluetooth to your mobile app, or Wi-Fi straight to your cloud endpoint or a private server, using GMIC's SDK and API.
3. Land in the job record
Your software attaches the note to the job, runs your own transcription and AI, and writes the result to the work order, report or quote.
You keep your speech-to-text, your AI and your data. GMIC provides the device, firmware, SDK documentation and integration support.
What has to be designed for field work?
- Controls that work with gloves and without looking — a large button or slide, with clear feedback.
- Audio tuned for job-site noise: compressors, fans, pumps, traffic. Microphone choice and placement are tested in the customer's real environments.
- Battery and charging sized for a full shift, with fast top-ups between shifts.
- Mounting that survives crawling, kneeling and ladders: clip, magnet or lanyard, chosen per trade.
- Housing that is easy to wipe down; any ingress rating is specified and tested per configuration.
- Recording signals and consent: visible and audible indicators and a consent workflow in your app. Recording-consent rules differ by state; California, for example, requires all parties to consent.
- Fleet operations: provisioning, OTA firmware updates, device authentication and encrypted firmware.
Which existing GMIC platforms fit field service?
MIC01
Push-to-talk, 8.8 g, up to 8 hours, Bluetooth 5.3. For quick job notes sent through a mobile app.
MIC05
Aluminum body, up to 10 hours, Wi-Fi + Bluetooth 5.3, 1 GB storage, hardware noise reduction. For longer visits and customer conversations.
MIC06
Up to 9 hours, Wi-Fi + Bluetooth 5.3, 1 GB storage, NFC, encrypted firmware, SDK / API and private-server deployment. For fleets with direct upload.
Each can be customized without new industrial or mechanical design, or used as the reference for a full ODM program. We are also developing a wearable vest form factor (HA-VEST01) for work that needs more than audio; it is in prototype iteration and pilot preparation and not available for order.
How should a field device pilot be run?
- One job type. For example, routine HVAC maintenance visits — not a mix of trades and configurations.
- A small group. Two or three technicians and a set of comparable jobs, with the current process measured the same way as a baseline.
- Measure the whole workflow. Time from job to finished report, follow-up questions from the office, missing fields — including the time spent reviewing and correcting anything automated.
- Log every failure. Notes not captured, devices not worn, integration errors. A pilot that hides its failures cannot tell you whether to scale.
- Decide. Scale, adjust the device or workflow, or stop.
What MOQ and timeline should you plan for?
| Path | What changes | Typical MOQ |
|---|---|---|
| Proof of concept | Existing platform connected to your app for field testing | Small runs, evaluated case by case |
| Platform customization | No industrial or mechanical design changes: branding, packaging, firmware, cloud endpoint | Around 500 units |
| Full ODM | New industrial and mechanical design (ID/MD), tooling, PCB, audio, battery | Around 2,000 units |
The simplest proof of concept can be delivered in as little as 2 weeks with an expedite fee. Platform-based prototype / MVP delivery is typically 25–45 working days after scope and specifications are agreed, before production launch; small-batch production follows about 40 working days after MVP validation and production readiness approval; the volume ramp reaches steady delivery 20–45 working days after the small batch. Component supply is the main variable.
Engineering and production are in Shenzhen, with customer work run from Anaheim, California. Manufacturing is carried out by GainStrong (Shenzhen GainStrong Technology Co., Ltd.), part of the same group.
Frequently asked questions
Four kinds of vendors: rugged wearable and headset makers such as Zebra and Honeywell (strong in warehouses and logistics), consumer AI recorder makers (built for individuals and their own apps), body-worn camera makers (video-first), and hardware ODMs such as GMIC that build custom voice capture devices under a software company's or service network's own brand.
No. The device captures what the technician says on site and hands it to your app or backend through an SDK or API; your software then writes it to the field-service platform you use.
Yes. The device delivers audio and metadata to your app, cloud endpoint or private server. Your speech-to-text, AI and data stay yours.
Customization of an existing platform without industrial or mechanical design changes typically starts around 500 units. A full ODM program with new industrial and mechanical design (ID/MD) typically starts around 2,000 units. Proof-of-concept runs are evaluated case by case.

Devices can provide visible and audible recording indicators and support a consent workflow in your app. Consent rules differ by state; California, for example, requires all parties to consent. Your legal team sets the policy.
Pick one job type, two or three technicians and a set of comparable jobs. Measure the current process as a baseline, then measure the whole new workflow, including review and correction time, and log every failure before deciding to scale, adjust or stop.
