Visual Speech Intelligence for Everyone
The multimodal AI infrastructure that understands human communication through vision and sound—empowering developers, enterprises, and creators to build applications that work in silence, noise, and everything in between.
Flibx combines advanced lip-reading, audio-visual fusion, and real-time processing into a single platform. Whether you're building AR applications, accessibility tools, or global content platforms, Flibx delivers accurate speech recognition when traditional audio-only solutions fail.
Why Audio-Only Speech Recognition Isn't Enough
For decades, speech recognition has relied exclusively on audio signals. But audio fails in the real world—in noisy factories, silent environments, through PPE masks, or when privacy demands no sound.
Noisy Environments
Audio-based speech recognition accuracy drops from 95% in quiet settings to below 10% when background noise exceeds 85 dB. Manufacturing floors, construction sites, airports, and busy restaurants render traditional speech-to-text unusable.
Silent Communication
Military operations, covert security, and privacy-sensitive environments require communication without sound. Audio-only systems are incompatible with these scenarios.
Accessibility Barriers
466 million people globally are deaf or hard of hearing. Audio-only communication tools exclude this population. Visual speech understanding is a fundamental human requirement.
Visual Speech Intelligence That Works Everywhere
Flibx is the first multimodal speech intelligence platform designed for the spatial computing era. By combining advanced lip-reading AI with audio-visual fusion, we enable accurate speech recognition regardless of conditions.

How Flibx Understands Visual Speech
Flibx uses state-of-the-art transformer-based neural networks trained on multimodal speech data. Our architecture processes visual and auditory signals in parallel, fusing them intelligently to deliver superior accuracy.

INPUT
Capture Multimodal Data
Video Input: Accepts live camera feeds or recorded video (MP4, WebM, streams). Requires minimum 480p resolution at 24 fps, optimal at 1080p/60fps. Audio Input: When available, processes audio streams in standard formats (WAV, MP3, AAC). Preprocessing: Face detection, mouth region extraction, audio normalization in real-time.

Visual Speech Model: Transformer-based encoder processes lip movements, tongue position, and facial expressions frame-by-frame. Audio Model: Parallel acoustic analysis identifies speech patterns and speaker characteristics. Fusion Layer: Proprietary algorithm combines predictions using confidence weighting. Language Understanding: Contextual models refine transcriptions based on grammar and vocabulary.

OUTPUT
Accurate, Actionable Results
Real-Time Transcription: Delivers text with sub-500ms latency. Streaming mode provides word-by-word results. Metadata & Confidence: Includes confidence scores, speaker identification, language detection, and timestamps. API Response: Structured JSON output with transcript, metadata, and optional features like emotion detection. Export Options: Plain text, SRT subtitles, VTT captions, or API callbacks.
This architecture enables Flibx to achieve 92-94% accuracy in ideal conditions, and maintain 85-90% accuracy even when audio is severely degraded—far surpassing audio-only systems that drop below 20%.
Performance That Proves Itself
We don't just claim superior accuracy—we prove it. Below are transparent benchmarks from real-world testing across diverse acoustic environments. Every metric is reproducible.
Accuracy Across Conditions
Quiet (< 40 dB)
Moderate (60 dB)
High Noise (85+ dB)
Complete Silence
Why Multimodal Wins
Traditional audio-only speech recognition collapses in real-world conditions. When factory noise exceeds 85 dB, accuracy drops below 10%. Flibx maintains 93% accuracy by prioritizing visual speech signals.
In complete silence—where audio-only systems achieve 0%—Flibx delivers 92% accuracy through pure lip-reading. This isn't incremental improvement. It's solving fundamentally different problems.
Real-Time Performance
| Platform | Model Size | RAM Usage | Latency | Accuracy |
|---|---|---|---|---|
| Cloud API | N/A | N/A | <200ms | 94% |
| iPhone 15 Pro | 250 MB | 1.2 GB | 120ms | 92% |
| Meta Quest 3 | 180 MB | 800 MB | 150ms | 90% |
| Jetson Nano | 300 MB | 2 GB | 200ms | 93% |
| Desktop (CPU) | 400 MB | 3 GB | 80ms | 94% |
Known Limitations & Edge Cases
While Flibx achieves industry-leading accuracy, certain conditions reduce performance:
- • Heavy Facial Hair: Reduces accuracy by 10-15%
- • Extreme Head Angles: Beyond ±45° horizontal degrades recognition
- • Poor Lighting: Below 50 lux, visual accuracy drops
- • Fast Speech: Above 200 words per minute, accuracy declines 5-10%
- • Obscured Faces: N95/surgical masks reduce accuracy but maintain 70-80%
