Words supply the message
In a text-first workflow, you write the script before generating speech. Short sentences, punctuation, and explicit pronunciations give you a better starting point than a dense paragraph. Listen for misplaced pauses or emphasis; a fluent reading can still change the intended meaning.

A voice supplies the delivery
A general synthetic voice does not require you to imitate a real person. A recording-informed voice is different: the source speaker should know how the recording will be used and agree to that use. Do not treat a publicly available clip as permission to reproduce someone's identity.

Review supplies the safeguard
Listen to the full output rather than judging a short preview. Check names, numbers, emotional tone, and any sentence that could sound like an instruction from a real person. If listeners might mistake synthetic audio for an authentic recording, label its origin when you share it.
