Making Every Conference Understandable.
Real-time captions and multilingual translation for live events — powered by on-device AI.
ConferenceCaptioning gives conference organizers and AV production teams a reliable, low-latency way to make spoken presentations fully accessible to Deaf and hard-of-hearing attendees while simultaneously reaching global audiences across languages.
Built for conferences, live events, AV production, institutions, houses of worship, and enterprise environments.
Ultra-low latency. Real event speed.
Watch ConferenceCaptioning process continuous spoken presentations with rapid word-by-word accuracy and instant attendee delivery across multiple simultaneous live environments.
Live production footage showcasing real-time on-screen and mobile delivery.
Live streaming captions in under 15 seconds.
Designed to deploy effortlessly on existing event infrastructure without lengthy training or cumbersome hardware installations.
Launch & Stream
Launch the application on the host machine, select the audio feed, and instantly generate the live event session QR code.
Share Access
Project the QR code onto main stage screens, print on attendee lanyards, or display at room entrances for seamless room access.
Audiences Follow Live
Attendees scan with any standard smartphone camera to follow live captions and choose their preferred language in real time.
Live events still leave people behind.
Traditional live event environments create significant friction when addressing accessibility compliance and international language support.
Accessibility Gaps
Deaf and hard-of-hearing attendees rely on accurate, real-time captioning that is frequently omitted due to production complexity.
Language Fragmentation
Multilingual attendees struggle to follow fast-paced keynotes when real-time translation is unavailable or cost-prohibitive.
Network Vulnerability
Cloud-dependent transcription tools introduce an uncontrollable point of failure on congested conference Wi-Fi networks.
Workflow Friction
AV engineers need software that integrates natively into standard video switchers rather than cumbersome standalone workarounds.

AI that runs where the event happens.
ConferenceCaptioning processes live speech directly on the host machine. By executing optimized transcription and translation models locally, latency drops to near-instantaneous levels while eliminating dependency on venue bandwidth.
Stage Screens
Direct HDMI / DisplayPort confidence monitors and main stage displays
Attendee Mobile
Local QR access via personal browser — zero app installation needed
Broadcast & Production
Native integration with OBS, vMix, ProPresenter, and H2R Graphics
When the internet goes down, the captions don't have to.
Production teams cannot gamble on venue internet stability. Because ConferenceCaptioning runs neural models locally, your event remains completely protected from outside connectivity drops.
Multi-System Automatic Failover
A primary and backup Mac operate on the same local network. If the primary host fails or drops audio, the backup system automatically assumes real-time output, complete with configurable retry intervals and alerts.
✓ Designed for the realities of live mission-critical production.
One event. Every audience.
Deliver captions and multilingual text across multiple endpoints simultaneously without adding operational overhead.
1. Stage Displays
Project high-contrast captions on main stage screens, side monitors, or downstream confidence displays. Proven live at major events like the NJEA Conference.
2. Attendee Devices
Attendees scan a simple QR code at their seat to view live captions on their personal phones or tablets in their preferred language. No app download required.
3. AV & Broadcast Workflow
Seamlessly feed live subtitle overlays into live streaming switchers and production software including OBS, vMix, ProPresenter, and H2R Graphics.
Accessibility shouldn't stop at one language.
Break international communication barriers. ConferenceCaptioning supports multilingual translation across 65+ languages in real time.
Built for the people who make events happen.

ConferenceCaptioning has transitioned from a specialized accessibility utility into a robust commercial platform serving event producers, academic institutions, and enterprise organizers across multiple continents.
“It seems like a no-brainer for every conference to use this technology to make auditory content accessible for all attendees.”
“Easy to use and simple to integrate into our existing setup.”
Engineered specifically for production environments.

Why now?
Rising Accessibility Expectations
Regulatory frameworks and societal expectations have made accessibility non-negotiable for enterprise and international events.
Global, Distributed Audiences
Conferences are more international than ever. Simultaneous multilingual communication is rapidly becoming a standard requirement.
On-Device Silicon Maturity
Modern hardware silicon now enables powerful neural speech processing locally without relying on fragile cloud APIs.
“Every voice heard.
Every audience included.”
Our vision is to make real-time accessibility and multilingual communication a standard foundational element of live production — rather than an expensive, specialized service bolted on after the event is designed.
Built from accessibility, not just software.
ConferenceCaptioning was created by a dedicated team with deep technical roots in building assistive communication technologies for the Deaf and hard-of-hearing community through BeAware.
Led by founder Saamer Mansoor, a software engineer with extensive experience in real-time communication systems, mobile software, and event accessibility, ConferenceCaptioning combines user-centric empathy with enterprise-grade performance engineering.
Our algorithms, interfaces, and contrast standards are derived directly from real-world testing alongside Deaf and hard-of-hearing individuals.
