Mark proper names, numbers and intentional pauses in the script.
- 2Produce a short permitted sample
Produce a short permitted sample, listen with the intended audience and inspect the audio file in the destination editor.
- 3Keep pronunciations separate from words
Keep pronunciations separate from words to be spoken.
- 4Recheck the final edited version
Recheck the final edited version rather than approving the first audition.
Choose a workflow that fits
Keep a human-recorded option when emotional direction or a sensitive pronunciation is central. Avoid comparing a prerecorded clip with a live conversation as if they were the same workload.

The correction in our worked example
The correction preserves the named person and the quarter-hour. It is an editorial script exercise; no vendor voice was auditioned.
Fictional narration: “Meet Mira at 3:15.” The name is pronounced MEE-rah; the time must remain explicit.
Meet Myra at three.
Meet Mira at three fifteen. Pronunciation note: MEE-rah. Keep the note out of spoken delivery.
Build and inspect the handoff
Mark proper names, numbers and intentional pauses in the script. Produce a short permitted sample, listen with the intended audience and inspect the audio file in the destination editor. Keep pronunciations separate from words to be spoken. Recheck the final edited version rather than approving the first audition.
Approve the spoken script
Check the time and pronunciation instructions before generating audio. After an audition, inspect the delivered file as well as the voice; the recipient needs the right words in a usable format. Use a human narrator when pronunciation direction or emotional nuance is the core requirement.
Compare the full cost
Compare characters, audio duration and regeneration costs using the vendor’s actual billing unit. Record consent and permitted use for any custom voice before testing it.
Creative production questions
Can I use any cloned voice for narration?
Use only a voice you are authorized to use and check the provider’s current consent and usage requirements.
When is a simpler workflow a better choice?
Use a human narrator when pronunciation direction or emotional nuance is the core requirement.
