Task 089: Dialogue Speaker Attribution Re-review

Status: DONE

Motivation

Human directive: 文字起こしの話者なども全体の文脈も踏まえながら再度見直すこと

Scope

Re-review all 5 episodes' Phase 2 speaker attribution with full cross-episode context:

• EP01: 86 entries, 6 speakers, 8 scenes
• EP02: 102 entries, 5 speakers (was 4; added guest-esper), 9 scenes
• EP03: 53 entries, 4 speakers, 10 scenes
• EP04: 34 entries, 5 speakers, 10 scenes
• EP05: 113 entries, 5 speakers, 13 scenes

Review approach

1. Read all 5 episodes' dialogue sequentially to build full character context
2. Check speaker assignments against:

- Voice characteristics (きりたん=ぞんざい語, ケイ=丁寧語, etc.)

- Scene context and character knowledge

- Cross-episode consistency (same character should speak consistently)

1. Correct any misattributions
2. Flag remaining uncertain entries for manual review
3. Update reports if any corrections change cited dialogue

Findings

EP01

• 10 uncertain entries — all due to ASR quality (VOICEROID audio)
• No clear misattributions found; all speaker assignments consistent with character speech patterns
• No corrections needed

EP02 — 3 corrections made

1. "何だ、ここはどこなのか？" (604600ms, Scene 6): Changed kiritan → guest-esper

- Context: Immediately after ケイ's "目覚めはよろしいようで" (waking greeting), followed by ケイ explaining about エスパー

- The confused, disoriented question fits someone waking from cold sleep, not きりたん

1. "故郷ではいつも星を眺めていたの" (697000ms, Scene 6): Changed enceladus-keeper → guest-esper

- Time series error: Scene 6 is before Enceladus arrival (Scene 7 starts at 760000ms)

- Female speech with nostalgic content about homeland — fits the Esper guest

1. "あなたは自由な人だから、私を選んでくれたのね" (718320ms, Scene 6): Changed enceladus-keeper → guest-esper

- Same time series reasoning — still in Scene 6, before Enceladus

- Grateful feminine speech directed at きりたん — fits the rescued Esper

Added new speaker: guest-esper (ゲスト（エスパー）/ Guest (Esper)) to EP02 speaker list.

EP03

• 1 uncertain entry: "捨てるしかないでしょう" (27840ms)
• Reviewed: でしょう here is rhetorical推量 ("have no choice but to discard it, right?"), not polite form
• Direct topic continuation with next きりたん line ("中身は死体だったんだからな")
• Kept as きりたん, updated note with analysis reasoning

EP04

• 0 uncertain entries
• All speaker assignments verified — no corrections needed

EP05

• 1 uncertain entry already flagged: "わね" ending atypical for ケイ (line ~293)

- File already correctly notes this could be Titania control station

- No correction possible without audio verification

Remaining uncertain entries (for future video verification)

• EP01: 10 entries (ASR quality, no clear speaker mismatches)
• EP02: 2 entries (ASR quality)
• EP03: 1 entry (confirmed きりたん, kept for documentation)
• EP05: 1 entry ("わね" anomaly)

Dependencies

• Tasks 028, 029 (Phase 2 attribution — DONE)
• Task 079 (transcription-report sync guideline — DONE)
