Miscommunication from Accented English Costs Lives and Billions
- Over 80% of aviation incidents involve communication breakdowns (ICAO, 2010).
- Accented English is a leading cause, delaying readbacks and risking operational safety.
- Airlines lose $33 billion annually due to communication errors and reroutes (Flight Safety Foundation, 2018), with each minute of delay costing $72-$100 (FAA, 2018).
- This problem is only getting worse as global aviation is projected to double by 2040 (ICAO, 2019), bringing even more international pilots with diverse accents into daily operations.

Accented Misunderstandings Jeopardize Multi-Billion Dollar Space Missions
- Multinational space crews operate with diverse English accents, where a single misunderstood command can risk multi-billion-dollar missions (NASA, 2015).
- Astronaut training emphasizes accent clarity because communication errors during launches, docking, or EVAs can be catastrophic (Kanki et al., 2019).
- This risk is growing, with over 20 new multinational space missions planned annually (NASA, 2021), increasing the number of crews with varied accents and compounding operational hazards.

Accented English Risks Security and Mission Success
- NATO forces operate in 30+ languages (NATO, 2020).
- Accented English in joint missions leads to operational confusion and delayed decisions, compromising security.
- Coalition forces rely on rapid, accent-neutral communication for tactical success (Defense Language Institute, 2019).

Accented Miscommunication Costs the Trucking Industry Billions
- The trucking industry loses over $1.5 billion annually due to miscommunication delays (ATRI, 2018).
- Drivers with accented English struggle with dispatcher instructions and DOT compliance, increasing safety violations and accident risks (FMCSA, 2021).
- This problem is worsening as the US trucking workforce has become 40% more linguistically diverse over the past decade (American Trucking Associations, 2020), increasing daily risks.

Accented Speech Endangers Patients in Critical Situations
- 80% of medical errors involve miscommunication (The Joint Commission, 2015).
- Accented English adds confusion during high-stress handoffs and air medical transport, delaying treatment and threatening lives.
- This risk is escalating because by 2030, 30% of US healthcare workers will be foreign-born (Migration Policy Institute, 2022), leading to even greater accent diversity in critical care teams.
- Improving clarity can increase patient survival by up to 30% in critical transfers (Hilligoss & Cohen, 2011).
