coverage_check.py REVIEW REQUIRED 84.61 % coverage, 7 gaps >= 3 s, 0 blocks past media end, 3 out of order
srt_hygiene.py PASS 741 = 741 blocks, 1482/1482 skeleton lines byte-identical, 6 markers
Coverage of 84.61 % is block-duration against runtime, not lost speech. This is a slide talk with long pauses. Every gap was read on both sides; see below.
Gaps and Out-of-Order Blocks
Six of the seven gaps at or above 3 seconds close cleanly: the block before ends on terminal punctuation and the block after opens a new thought, or the sentence joins across the seam and reads complete.
| Gap | Verdict |
|---|---|
| 12:17.480 to 12:20.680 | Clear. “And they’re mostly tropical.” to “cockroaches are really tropical.” |
| 17:38.640 to 17:42.520 | Clear. Sentence boundary both sides. |
| 31:29.240 to 31:35.500 | Speech loss. Block 443 ends mid-word. See below. |
| 36:02.500 to 36:05.820 | Clear. New slide at block 496. |
| 37:33.680 to 37:38.320 | Clear. “cockroach research with” joins “American roaches” across the seam. |
| 44:23.500 to 44:26.579 | Clear. Sentence boundary both sides. |
| 47:45.800 to 47:50.440 | Clear. Sentence boundary both sides. |
The 31:29 gap is a real hole, and it was recovered. Block 443 was cut at “either American ro”. An audio pass over 31:20 to 31:42 recovers both the block’s own tail and roughly 6 seconds of speech that falls inside the gap: “and there’s a big smoky brown cockroach coming in.”
Per project convention, recovered words go back into the fixed skeleton by attaching to one of the two bracketing blocks, since Stage 1 may not create a block or move a timestamp. Placement is a judgment and is recorded as one here: the recovered clause was attached to Block 443 rather than Block 444, because prosody and subject both continue Block 443’s description of the video, while Block 444 opens a new topic (“We talked about tree hole habitats”). The words themselves are audio-confirmed; only the placement is a choice.
The timing still does not match the speech, which now sits in a window ending at 31:29.240 although it was spoken through 31:35.500. That is a caption-editor timing repair, and it belongs with the line-splitting pass.
Three out-of-order blocks (65, 167, 682) are ASR window artifacts, each a short false start timestamped after the longer block that repeats it (“It’s a…”, “Cockroaches are”, “She…”). Timestamps left untouched per Bedrock. Sort by start time, never by index.
Corrections Applied
Institutions and Programs
- “The ES unveiled” → “The ESA unveiled” (Block 50)
- “insoc.org” → “entsoc.org” (Block 93)
- “both ACES and CIT people via feather in the cap” → “both ACEs and CIT people. Be a feather in the cap” (Block 91)
Scientific Names
- “Urocotus floridanus” → “Eurycotis floridana” (Block 305)
- “Paraponita brunia” → “Periplaneta brunnea” (Block 496)
- “blatteria, blattodia, blatella” → “Blattaria, Blattodea, Blattella” (Block 339)
- “the Oregonian cockroach” → “the Oriental cockroach” (Block 558)
- “the Turkistan cockroach” → “the Turkestan cockroach” (Block 555)
Chemical and Product Names
- “a night band, add beyond IG” → “Niban, Advion IG” (Block 378) — audio confirmed
- “avion bait” → “Advion bait” (Block 438); “Adveon” ×2 → “Advion” (Block 604)
- “endoxycarb” / “in doxycarb” → “indoxacarb” (Blocks 618, 619)
- “alopecin” → “allopurinol” (Blocks 268, 270); “albupirinol” → “allopurinol” (Block 283)
- “a Durst Band product called Killmaster” → “a Dursban product called Killmaster” (Block 527). Block 529 names chlorpyrifos, which is the same product.
- “went to work for Valen” → “Valent” (Block 610). Both engines produced “Valen”; settled on sense against the company name.
- “Whitmire Microgen” → “Whitmire Micro-Gen” (Block 731)
Technical Terms
- “Kraken crevice pest control” → “crack and crevice pest control” (Blocks 732, 733). Block 726 already had it right.
- “a cell called a uricite” → “urocyte” (Block 204), matching Block 202
- “Otheca” → “ootheca” (Block 422); “Oetheca” → “ootheca” (Block 566)
- “a pair of domestic” / “pair domestic” → “peridomestic” (Blocks 297, 323, 344)
- “endemil moth” → “Indianmeal moth” (Block 331)
- “the air moon is very still” → “the air movement is very still” (Block 338). Both engines produced “air moon”. Settled on sense: the speaker gives the same list as “warm, no wind, and moisture” at Block 346 and “warm, humid, and no air movement” at Block 450.
- “tree holes addicts crawl spaces” → “tree holes, attics, crawl spaces” (Block 344)
- “the facial boards” → “the fascia boards” (Block 465)
- “a court can” / “a court paint can” → “quart” (Blocks 578, 580)
- “med bugs” → “bed bugs” (Block 133); “bedbugs” → “bed bugs” (Block 126)
- “They can eat a lot of jellyfish” → “They can eat a lot of gel bait” (Block 542) — audio confirmed
- “smoky round road” → “smoky brown roaches” (Block 478); “smoking brown roaches” → “smoky brown roaches” (Block 474)
- “the rug just come out at night time” → “the roaches come out at nighttime” (Block 486)
- “the fordwoods roach” → “the Florida woods roach” (Block 319)
- Common names lowercased where the ASR title-cased them (Blocks 419, 422, 552)
Grammar and Recovered Speech
- Block 110: “the research and just wanted” → “the researcher just wanted”; “so I took a bunch” → “so they took a bunch”; “with a game food but” → “where they gave food but”. All three audio confirmed.
- Block 320: “roaches back to what health.” → “roaches back that would have” — audio confirmed; joins Block 321 cleanly.
- Block 443: “left is either American ro” → “left is either American roach or a, and there’s a big smoky brown cockroach coming in.” — audio recovered; the clause after the comma was spoken inside the 31:29 gap and is attached here by the judgment recorded above.
- Block 268: “This alopecin removes the enzyme” → “This allopurinol pill removes the enzyme” — audio confirmed.
- Block 332: “They got to be one time” → “They’ve got to mate one time”
- Block 539: “I’m tubes of it” → “I mean, tubes of it”
- Block 581: “I got a Home Depot” → “I got at Home Depot”
- Block 25: “the Southeast Indians like that” → “the Southeast is like that”
- Block 371: “you’ll be living in the attic” → “they’ll be living in the attic”
ASR Artifacts on Silence
Blocks 147, 217 and 253 carry no speech. Whisper produced “Bye.”, “Bye-bye.” and “Thank you.” on silence, the familiar end-of-window hallucination. Block 217 runs 0.1 seconds. All three replaced with an [INAUDIBLE] marker and no speaker label, so nothing unspoken is attributed to Dr. Suiter or can be quoted downstream as speech.
Flagged for Verification
Three flags remain open. Each quotes the ASR token rather than a proposed answer.
- Block 268 [~18:56]:
[VERIFY: "PML"]— “precursors that build up and PML”. Two engines agree on the token. Allopurinol inhibits xanthine oxidase, so a precursor name is expected here, but no candidate is supported by the audio. Needs a human ear. - Block 419 [~29:27]:
[VERIFY: "horses"]— sentence-initial discourse word starting a new slide. Second engine gives “Or it’s just”. No technical content either way. - Block 536 [~38:53]:
[VERIFY: "it works in blue diamond", two boric acid bait product names]— both engines produce the same string. These are product names, so no guess is permitted. Needs the team or a catalogue of period boric acid baits.
Audio clips for the pass are kept at ~/Downloads/_gtbop_clips/ (11 WAVs, 16 kHz mono).
SRT Format Compliance
✅ All timestamps preserved exactly as original (1482/1482 skeleton lines byte-identical)
✅ All sequence numbers maintained, 1..741 contiguous
✅ Blank lines between segments preserved
✅ No segments merged or split
✅ Block count: 741 original = 741 corrected ✓
⚠️ 629 of 741 lines exceed 42 characters and 0 blocks exceed 2 lines. The source is one long line per block. Line splitting is deferred to the caption-editor pass, per project convention, since it cannot be done without touching block structure.
Total Corrections: 57 edits across 51 blocks, 11 of them audio confirmed, 1 of which recovers speech from a coverage gap
Processing: Complete file (741 subtitle blocks, 2,964 lines)
