A three-word proper name drives the difficulty here, and the first casualty is its longest, least familiar middle word: periodical (28.5%). Across 386 attempts speakers kept 73.6% and scored 3.19/5 — they hold the outer Computer and Archive but lose the middle periodical, and the final /v/ of archive (accuracy 62.5) is weak too.

This is a locating line with a long proper name: the Computer Periodical Archive is in the basement. Which archive, and where.
Each word is shaded by how often it was dropped across 386 attempts. Hover for the exact rate. This sentence is one case in the Listen and Repeat research across 23,000+ sessions — where endings and late words drop most.
The three most fragile words here are periodical (28.5%), computer (11.4%), archive (9.3%) — when you record your own version, check first that each of these survives.
These are sounds with substantial measurements in this sentence, not a generic pronunciation list. Automatic assessment places /v/ lowest among the sounds shown.
| Sound | Measurements | Avg accuracy | Below 60 |
|---|---|---|---|
| /v/ | 219 | 62.5/100 | 40.2% |
| /ɹ/ | 674 | 81.4/100 | 16.0% |
| /d/ | 459 | 84.7/100 | 7.0% |
Omission rates show the pattern, not its cause. Position, word length, and endings still give us specific practice hypotheses to test.
periodical
28.5% omitted
Periodical is the middle word of the proper name Computer Periodical Archive — five syllables, the longest and least familiar — and the most-dropped word in the sentence, since speakers hold the first and last words but lose the middle.
Practice: Say the three-word name word by word — Computer, Periodical, Archive — practising the fragile Periodical slowly.
computer
11.4% omitted
Computer is the first word of the name and links into a long run of three, so it is easily compressed.
Practice: Steady Computer as the start of the name before adding the next two words.
archive
9.3% omitted
Archive is the last word of the name, and its final /v/ scores low in automatic assessment, so it is often unclear.
Practice: Close the final /v/ of archive so the name ends cleanly.
Place splits between complete meaning groups, following the chunking method. The slashes are memory boundaries for practice, not mandatory audible pauses.
| Speakers paused before | Share of pauses | Placement |
|---|---|---|
| “is” | 10.9% | Mid-phrase |
| “in” | 8.6% | Natural split |
| “archive” | 6.5% | Mid-phrase |
| “basement” | 3.9% | Mid-phrase |
Two blocks: The Computer Periodical Archive is located / in the basement.
Drill the three-word name, especially the fragile middle Periodical: Computer, Periodical, Archive, all in full.
Add in the basement, minding the final /v/ of archive.
Do not rely on a vague feeling of success. Meet all four checks twice in a row before increasing sentence length.
Record it once and see your own version of the heat map above — which words you dropped and where your pauses landed.

Use 2 meaning groups: The Computer Periodical Archive is located / in the basement. Preserve the information skeleton first, then check the final words and endings.
periodical (28.5%), computer (11.4%), archive (9.3%) have the highest omission rates among the 386 attempts summarized here.
Pause between complete meaning groups rather than inside a noun or verb phrase. Use pauses as a memory scaffold, then work toward a connected delivery.
