speech intelligibility engineering
Measured intelligibility for high-stakes communication.
Accent Innovations builds the technology that objectively measures, trains, and certifies speech intelligibility in safety-critical industries - starting with aviation.
US & International Patent Pending
Proprietary ORONYM™ & VCAM™ methods
When being understood isn't optional.
Safety
The Safety Crisis
ICAO English proficiency has been mandatory since 2008. Accent-related miscommunication is a documented factor in fatal aviation incidents.
Science
The Science Gap
Vowels drive intelligibility more than consonants. Yet conventional speech therapy cannot train them - there are no articulatory touch points for vowels.
Measurement
The Measurement Problem
Legacy scoring uses pooled historical norms that can produce false passes and false fails for diverse speakers.
Three technologies. One closed loop.
Assessment → Training → Certification. US & International Patent Pending Proprietary ORONYM™ & VCAM™ methods.
ORONYM™
Trains target vowels by anchoring new sounds to familiar ones. Learners produce acoustically correct speech through articulation patterns they already know. No abstract phonetic instruction required.
VCAM™
Real-time intelligibility scoring against word-specific acoustic corridors, aligned with perceptual reality.
Pierson (2026)
Corridor norms derived from speaker-calibrated reference data — not legacy pooled datasets. Calibration and runtime use the same validated extraction pipeline. Peer-reviewable results.
Observable progression, not black-box scoring.
Every session produces explainable evidence. Instructors and operators see how learners converge on target corridors over time.
