Vowel Omission and the Homograph Trap
A candidate preparing for the 80 wpm dictation finds that in a 400-word office passage, 16 outlines are ambiguous because vowel signs were omitted. Five pairs are homographs: 'principal/principle', 'board/bored', 'sight/site', 'there/their', and 'whether/weather'. The candidate's shorthand manual says context decides, but the passage includes 'The principal/principle objection' and 'the board/bored meeting', where either reading is grammatically possible. If she inserts vowel signs throughout, her writing speed drops from 80 to about 66 wpm, which would cost roughly 70 words over five minutes. If she omits all vowels, she estimates 12 of the 16 ambiguities can be resolved from context, leaving 4 likely errors. The error allowance is 5 per cent of 400 words, i.e. 20 errors, but she already expects 9 other transcription errors.
1. Decide whether the candidate should insert vowel signs throughout, selectively, or not at all, supporting the choice with the numbers given.

Do not insert vowel signs throughout. The arithmetic is against it: a drop from 80 to 66 wpm costs about 14 wpm × 5 minutes = 70 words, far more than the four errors it might save. Her expected total without vocalisation is 9 + 4 = 13 errors, which is inside the 20-error allowance.
Selective insertion is the rational middle. Mark only the outlines where both readings fit the sentence and the meaning changes. 'Principal/principle objection' is the clearest candidate; 'board/bored meeting' is less risky because collocation strongly favours 'board'. A small distinguishing vowel sign or a changed joining, written for only two or three outlines, costs almost no time and preserves a margin. The rest should be left to context. The decision is about expected error cost, not about proving that every vowel can be supplied.
2. State the shorthand principle that governs this choice and explain how to judge which homographs actually need disambiguation.

The governing principle is that vowel omission is a speed device, not a claim that the vowels are unknown. The consonant skeleton, position and joining carry the word; context carries the homograph. Phrase outlines are more dangerous because a phrase may freeze a wrong reading into the notes.
For each pair ask three questions: (a) does the sentence remain grammatical under both readings? (b) which collocation is more frequent in office English? (c) would a wrong choice change the administrative or legal meaning? Only when (a) is yes and (c) is serious should the outline be vocalised. 'Sight/site' and 'there/their' are usually settled by grammar; 'whether/weather' by syntax; 'principal/principle' needs the most care because both can modify 'objection'. This is a judgement about expected error cost, not a rule that all homographs must be distinguished.
