Narration QC (double-checked)
| Dimension | Choice | Why |
|---|---|---|
| Voice | en-US-ChristopherNeural | Edge TTS “News / Novel · Reliable, Authority” — best scholarly-pastoral fit for a 1971 mission dissertation among bake-off candidates |
| Tempo | ~149 wpm measured (rate +0%) | Dense nonfiction target 145–155 wpm. Rejected Christopher −15% (~122 wpm — draggy) and over-slow Jenny −12% (~129 wpm) |
| Pitch | −1 Hz | Slight gravitas without muddiness |
| Loudness | ≈ −16.9 LUFS integrated, TP ≈ −1.6 dBTP | Streaming audiobook reference (−16 to −18 LUFS, TP ≤ −1.5) |
| Style | Warm authority, continuous prose | Section heads spoken as “Section one…” for breath; PDF ligature breaks repaired on speak layer only (AMT frozen unchanged) |
Bake-off summary (200-word open)
| Candidate | Rate | ≈ WPM | Notes |
|---|---|---|---|
| Christopher | −15% | 122 | Too slow for long-form |

| Guy | −5% | 149 | Tempo OK; “Passion” tone less pastoral |
| Andrew | −5% | 140 | Warm/casual Copilot feel |
| Jenny | −12% | 129 | Friendly; slower; better as alternate cast |

- Section transitions: Clear enough without theatricality?
- Compare prior pilot: Taiwanese female Ch.1 pilot was a different language/affinity experiment — this page is EN SKU A direction.
