Apophthengomai is used for speaking out in declarations, Spirit-enabled tongues, and a defense before Festus.

The attested use is speech expressed aloud: those filled with holy spirit begin speaking in other tongues in Acts 2:4, Peter addresses those in Jerusalem in Acts 2:14, and Paul answers Festus with true and rational words in Acts 26:25.

1. Speaking out in an address or utterance · dominant

   In Acts 2:4, the present middle infinitive occurs after the group began to speak in other tongues; the APB renders the surrounding clause "began to speak in other tongues as the spirit gave them to declare." In Acts 2:14, the aorist middle form introduces Peter's raised-voice address to Jews and Jerusalem residents, while in Acts 26:25 the present middle form occurs in Paul's reply to Festus; the APB renders him as "speaking true and rational words."

In the Anselm Project Bible: The APB presents the surrounding speech with "speak," "declared," and "speaking." Because it is a whole-verse translation, these varied English expressions do not establish separate meanings.
