Transcription accuracy collapses after a speed jump
A candidate's practice log shows a jump from 80 to 95 wpm dictation over two weeks. In the latest six-minute dictation at 95 wpm (570 words), the candidate wrote 540 words and transcribed them in 28 minutes, producing 19 errors. Error classification: 8 vowel omissions, 4 grammalogue substitutions, 3 conjunct simplifications, and 4 homophones such as तो/ते and कर/करा. The target is 100 wpm with 95% accuracy. The candidate's transcription rate is about 19 words per minute, and the exam gives a fixed transcription window. The candidate wants to add another 10 wpm next week. The teacher warns that the errors are now meaning-changing, not just spelling. Five weeks remain.
1. Diagnose the root cause of the error pattern and decide whether the candidate should add speed next week. Support the decision with the numbers given.

Do not add speed next week. The numbers point to a classic accuracy ceiling caused by pushing dictation beyond the candidate's stable writing rate.
Evidence:
- The candidate heard 570 words but wrote 540, so 30 words were missed outright. That is a 5.3% capture loss before transcription even begins.
- 19 errors in 540 written words is about 3.5 errors per 100 words, far from the 95% accuracy target (5 errors per 100 is the maximum, and meaning-changing errors are worse).
- The error mix is diagnostic: vowel omissions and grammalogue substitutions are not random spelling slips; they are signs of rushed outline selection. Homophones like तो/ते and कर/करा change meaning, so the examiner will penalise them heavily.
- At 95 wpm the candidate is already 5 wpm above the last stable speed. Adding 10 wpm will likely increase capture loss and worsen transcription time, not improve the score.
Decision: consolidate at 90 wpm until accuracy is at least 97% in practice, then move to 95 and 100 in 5 wpm steps. Speed should follow accuracy, not replace it.
2. Propose a five-week plan that improves both dictation accuracy and transcription speed, including how to measure progress each week.

Use a two-track plan: accuracy track and transcription track.
Weeks 1–2 (stabilise at 90 wpm):
- Three 5-minute dictations per week at 90 wpm. Transcribe within 20 minutes. Target: at least 97% word capture and no more than 1 meaning-changing error per 100 words.
- Daily 10-minute grammalogue drill: write each confused pair in phrases, then dictate the phrases at 60 wpm.
- After each transcription, classify every error into vowel, grammalogue, conjunct, homophone, or omission. Keep a running tally.
Weeks 3–4 (transcription speed):
- Keep dictation at 90–95 wpm but reduce transcription time by 10%. Use a 1:3 dictation-to-transcription ratio as a training target, not an exam rule.
- Practise reading back shorthand notes aloud before writing the fair copy; this exposes ambiguous outlines early.
- Do one 10-minute dictation per week to build stamina.
Week 5 (exam simulation):
- Two full simulations at 95–100 wpm with fixed transcription time. Target: 95% accuracy and completion within the window.
Measurement: record words captured per minute, errors per 100 words, transcription minutes, and meaning-changing errors separately. Progress is valid only when accuracy holds while speed rises.
3. How should the candidate handle homophones like तो/ते during transcription without losing time?
Read the worked answer
Handle homophones at the note-reading stage, not by guessing during fair copy.
Reasoning: Marathi homophones often differ by a single vowel sign or stroke, so the shorthand outline may be legible but the intended word is only clear from syntax. The candidate should:
- During dictation, add a small contextual cue only where the passage is genuinely ambiguous, such as the following noun or verb form. Do not annotate every homophone; that wastes time.
- During transcription, read the whole sentence before writing the disputed word. Marathi agreement and verb endings usually resolve तो/ते and कर/करा.
- If the sentence still does not resolve it, mark the word with a query symbol and continue; return after finishing the paragraph. This protects flow.
- Build a personal list of the ten most frequent homophones in the exam passages and drill them in sentence context, not as isolated words.
The judgement call is when to annotate: annotate only if the ambiguity cannot be resolved by the next three or four words. Over-annotation slows dictation; under-annotation creates meaning errors.
