TTS and human recording are different tools. I would use TTS for speed, drafts, and repeatable updates; I would use a real voice when personality is the product.
Use TTS when speed matters
TTS is excellent for drafts, frequent updates, internal material, and projects where speed is more important than a unique human performance.
Use recording when personality matters
A human voice can add emotion, humor, and brand personality that may be important for flagship campaigns or storytelling.
Combine both in production
Many teams use TTS to test scripts and timing, then record a final human version only when the script is stable.
Before you publish
- Use TTS for drafts and updates
- Use recording for signature content
- Test timing with TTS first
- Choose based on audience expectations
Multilingual quick notes
A simple way to try it
Start with one short paragraph from your own project. If the sample sounds clear, keep that version of the script and then record the full MP3. It is much easier to fix one paragraph early than repair a long file at the end.
