Place this clip at the very start of the edit, before your voice begins, then follow it with a background music loop kept under the speaking segment. For a lighter second half, switch that bed out after the main announcement ends.

This clip is a ten second musical intro titled Trusted News v1, built as a short speaker introduction with a fade. It gives a listener a serious, confident feeling, like a broadcast is about to begin and something important will follow. The track credit in its file tags is FesliyanStudios.
