Scenario challenges

Public service terminals need more than simple sound capture.

Government halls, bank counters, hotel receptions, retail service desks and self-service terminals often need clear two-party pickup. Standard omnidirectional microphones easily mix staff voice, visitor voice and surrounding lobby noise.

  • Separate staff and visitor voices for service recording, transcription or AI assistance.
  • Reduce lobby noise, queue conversations, device noise and public broadcast sound.
  • Support compact installation inside smart terminals or service counters.
  • Provide finished microphone devices when embedded design is not required.

Solution architecture

A/B role separation with independent directional pickup.

HAOKAI directional microphone modules combine focused pickup, left/right channel separation, noise reduction and automatic gain control to create a practical voice front end for counter conversations.

60

Independent Pickup Zones

Directional microphone elements focus on target areas and reduce voices outside the pickup angle.

A/B

Role Separation

Separated channels help systems distinguish staff and visitor voices in daily service workflows.

ODM

Module or Finished Device

Choose embedded modules or finished desktop microphones depending on product integration needs.

Selection guidance

Specify the conversation layout before selecting a counter service microphone.

Counter-service audio performance depends on the physical conversation zones and the terminal structure. Share the installation drawing and operating conditions early so the pickup direction, channel output and interface can be matched to the device.

Conversation zones

Define staff and visitor positions, counter depth and any glass, speaker or queue area between them.

Channel requirement

Confirm whether separate left/right recordings are needed for transcription, review or AI assistance.

Integration path

Choose an embedded module or finished device, then confirm mounting space, cable routing and host interface.

FAQ

Technical questions before integration.

What does role-separated pickup mean?

It uses independent directional pickup zones and separate channels to make two-party recordings easier to review. Actual separation depends on placement, room acoustics and overlapping speech.

Can two speakers be recorded on separate channels?

A suitable two-channel directional design can support separate staff and visitor capture. We recommend validating channel isolation in the final counter structure.

Is this suitable for noisy service halls?

Focused pickup and noise processing can reduce off-axis ambient sound, but queue noise, public announcements and speaker playback should be evaluated in the target environment.

Can the microphone be embedded in a terminal?

Yes. Module options can be matched to the terminal opening, acoustic path, interface and production requirements.
