For then will I turn to the peoples of a pure language, that they may all call upon the name of Jehovah, to serve him with one consent.
The curse of Babel was confusion of tongues, penalty for rebellion. God will restore one pure language and one worship. The Gentiles' lips became impure instruments of idolatry; He shall purge them. Whether Hebrew or another tongue, the God of the Hebrews shall be the sole object of worship.
AI summary
The judgment brings redemption to believers who wait for it. God does not turn His lip to the nations; rather He gives them pure lips, purged from the defilement of sin that marked them. Stripped of idolatry's corruption, they shall call on the Lord's name with one accord as a single man.

Commenting on Zephaniah 3:9-10
The Prophet must soften what came before, else the faithful would despair utterly. God gathers the nations for judgment, yes, but He turns His face toward the remnant with comfort. When He threatens, He speaks to the whole people; when He promises mercy, He addresses the elect alone, drawing them apart.
