Translation of "luzaroan" into English

Eta, halako batean, hitz egiten ari zenaren goma puskatu eta maskara erori zitzaion. Txema zen, zuri geratu zen, isildu eta atzean eseri zen. Luzaroan ez zen haren ahotsik entzun asanbladetan.

And then, all of a sudden, the rubber of the one who was talking broke and his mask fell off. It was Txema; he lost his color, fell silent, and sat back down. For a long time, his voice was not heard in the assemblies.
