Changes

Inconsistent vowel in derived forms: COUGHED, COUGHS

COUGH has two variants (AA1 and AO1), and COUGHING correctly has both. But COUGHED and COUGHS only had the AO1 variant, inconsistent with the base form.

Word	Before	After (main)	After (1)
COUGHED	K AO1 F T	K AA1 F T	K AO1 F T
COUGHS	K AO1 F S	K AA1 F S	K AO1 F S

British /tj/ instead of American /tʃ/: MATURED, IMMATURE

MATURE main entry uses CH (/tʃ/, standard AmE), and so do MATURES, MATURING, and IMMATURITY. But MATURED and IMMATURE only had T Y (/tj/, British).

Word	Before	After (main)	After (1)
MATURED	M AH0 T Y UH1 R D	M AH0 CH UH1 R D	M AH0 T Y UH1 R D
IMMATURE	IH2 M AH0 T Y UH1 R	IH2 M AH0 CH UH1 R	IH2 M AH0 T Y UH1 R

Wrong first vowel: PRIVATIZE

PRIVATE, PRIVATIZED, PRIVATIZING, and PRIVATIZATION all use AY1. Only PRIVATIZE had IH1.

Word	Before	After (main)	After (1)
PRIVATIZE	P R IH1 V AH0 T AY2 Z	P R AY1 V AH0 T AY2 Z	P R IH1 V AH0 T AY2 Z

Variant ordering: PSALM, PSALMS

The L in "psalm" is silent in standard AmE. Swapped so the silent-L pronunciation is the main entry.

Word	Before (main)	After (main)	After (1)
PSALM	S AA1 L M	S AA1 M	S AA1 L M
PSALMS	S AA1 L M Z	S AA1 M Z	S AA1 L M Z
