Severity
Mechanism
Exploits the gap between phonetic and textual representation. Misspellings, truncations, and word splits sound correct but don't match keyword patterns. Low effectiveness against frontier models that handle typos natively.
Detection
- Fuzzy keyword matching (edit-distance)
- Phonetic normalization (Soundex/Metaphone)
Mitigation

Phonetic canonicalizationHIGH
Chaining
