Local Private AI Meeting Transcription System
Short Description:
Private, accurate meeting intelligence – processed entirely inside your network.
Designed for enterprises, government organizations, and professional teams, the system combines the LX04 dual-microphone meeting terminal with a local DGX Spark AI node to capture meetings reliably, generate high-quality transcripts, identify speakers, and create actionable minutes without sending sensitive meeting data to the cloud.
✓ On-premises AI processing and local data storage
✓ Speaker diarization and voiceprint-based speaker matching
✓ Meeting summaries, key decisions, action items, and source timestamps
✓ Browser-based review, playback, export, deletion, and optional email delivery

Why It Matters
|
DATA PRIVACY Raw audio, voiceprints, transcripts, and model inference stay inside the customer network. |
FASTER FOLLOW-UP Automatically turn meetings into transcripts, summaries, decisions, and action items. |
TRACEABLE RESULTS Timestamped dialogue and source timestamps make decisions easier to review and verify. |
KNOWLEDGE ASSETS Convert meeting recordings into searchable, reusable organizational knowledge. |
Core Features
Reliable audio capture: Dual-channel, 8 kHz, 16-bit PCM capture with local chunk buffering, ACK confirmation, reconnection, and resume.
Local AI processing: VAD, dual-microphone enhancement, Chinese ASR, speaker diarization, voiceprint matching, and full-audio post-meeting reprocessing.
Actionable outputs: Timestamped dialogue transcripts, identified speakers, meeting summaries, key decisions, action items, and source timestamps.
Flexible management: Web-based playback, speaker naming, Markdown/TXT export, record deletion, and manual or automatic email delivery.
External recording support: Upload MP3, M4A, WAV, or AAC files; each file is retained as an independent record after transcription and intelligent summarization.
How It Works
|
01 START One-tap recording with continuous local buffering. |
02 RELIABLE UPLOAD Chunk validation, confirmation, and resume after disconnection. |
03 POST-MEETING AI Full-context transcription, diarization, voiceprint matching, and intelligent minutes. |
04 DELIVER RESULTS Review, replay, download, delete, or email results from the web console. |
Confidential meetings stay protected · Faster post-meeting work · Traceable decisions
Technical Overview

Deployment, Security & Extensions
Practical information for solution evaluation and website product-detail pages.
| Typical Use Cases
• Business decision meetings • R&D and technical reviews • Customer meetings • Internal training • Confidential and compliance-sensitive meetings |
Security & Deployment
Local closed loop: Raw audio, voiceprints, transcripts, and model inference remain within the customer network and local storage. Access control: Device tokens, HTTPS/WSS, and web login are supported; SMTP credentials and recipients are injected through protected environment configuration. Policy control: Meeting records can be deleted; automatic email can be disabled with one switch to prevent unintended delivery during testing. Deployment: Customer LAN, DGX Spark, local meeting terminal, and a modern browser; SMTP is optional. |
Optional Project-Based Extensions
• Industry terminology adaptation
• Multi-room access
• Custom data-retention policies
• Email templates and delivery policies
• Enterprise system / API integration
Operations & Data Governance
|
Containerized deployment Ingestion, transcription, diarization, minutes, and email services can be maintained independently. |
Health & status Service health, processing status, and failed retries are observable. |
Upgrade & rollback Source versions, deployment backups, and guides support controlled rollback. |
Data lifecycle Deletion, backup scope, and retention can follow customer policy. |
Confidential meetings stay protected · Faster post-meeting work · Traceable decisions · Recordings become knowledge assets
