Dictionary-style pages print IPA between slashes (e.g. tiger /'taiga/). Step 5h detects these patterns, looks up the headword in the IPA dictionary for proper Unicode IPA, and falls back to OCR text when not found. Converts /ipa/ to [ipa] bracket notation matching the rest of the pipeline. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
