Phenol will be more acidic than thiphenyl as both are in conjucgation but it doesn''t matters.

In Phenol -OH group induces less +M effect than -SH group in phenyl.

And acid character is inversely proportional to +M  and +I.

that''s why.

Thiophenol has appreciably greater acidity than does phenol. Thiophenol has a pKa of 6 vs 10 for phenol.This is because the lone pair of sulphur is more easily given to ring(than in phenol) and stabilised after losing the H+. Since the conjugate base is more stable the acid is more acidic.

Thiophenol is more acidic.phenoxide formed in phenol is stablized and pka value of phenol is more than thiophenol.thats way phenol is less acidic than thiophenol
