Custom Vocabulary for Indian Names & Brands
AI transcription handles common words well but stumbles on proper nouns - especially Indian names, regional brands, and domain-specific terms that did not appear frequently in training data. A custom vocabulary list prepared before transcription dramatically reduces the time you spend fixing these errors afterward.
By CapsAI · Updated 19 August 2026

Key takeaways
- Prepare a vocabulary list of names, brands, and technical terms before transcribing.
- Indian names with uncommon spellings are the single biggest source of proper-noun errors.
- Domain-specific terms (legal, medical, tech) need explicit correct spellings.
- A 10-minute vocabulary prep saves 30+ minutes of correction across a long recording.
Why Indian proper nouns are uniquely difficult
Indian names come from dozens of languages and have no single standard romanization. 'Shrinivas' might be spelled Srinivas, Shreenivas, or Sreenivasan depending on the family's preference. The AI cannot know which variant a specific person uses - it picks the statistically most common spelling, which is often wrong.
Brand names face similar challenges. Zerodha, Byju's, Cred, Swiggy, Zomato - these are common enough to be in AI vocabularies. But regional brands, startup names, and new companies are not. A fintech startup called 'Khatabook' might be transcribed as 'khata book' or 'kata book'.
Building your vocabulary list
Before transcribing, list every proper noun you expect to hear: people's names with their preferred spelling, company and brand names, product names, place names (especially smaller cities or neighborhoods), and any technical jargon specific to the topic.
For recurring projects - a weekly podcast, regular meeting series - maintain a running vocabulary file. Add new terms after each episode and carry the list forward. Over time, this becomes a comprehensive reference that dramatically reduces review time.
- People: full names with preferred spelling (Hrithik not Hritik)
- Companies: exact brand spelling including capitalization (PhonePe not Phonepe)
- Places: local spellings (Koramangala not Koramangla)
- Products: technical names as used by the company
- Jargon: domain terms that sound like common words

Names in Devanagari and other scripts
When transcribing into Devanagari, names need correct Hindi rendering. 'Priya' should be प्रिया not प्रीया. 'Rahul' should be राहुल not रहुल. These are obvious to native speakers but AI frequently gets matra length wrong on names because the model treats them as any other word.
For names that originate from one language but appear in another's script - a Tamil name in a Hindi transcript, or an English name in Devanagari - decide in advance how to render them. Consistency matters more than any single correct choice.
Using the vocabulary list during review
After AI transcription, search the output for each term on your list. Check that it appears with the correct spelling every time. AI inconsistency means the same name might appear three different ways in one transcript. Use find-and-replace to standardize.
Also search for phonetic variants the AI might have produced. If the name is 'Subramanian', search for 'Subra' to catch 'Subramaniam', 'Subramanyam', or 'Subramani'. For Hindi names, search for the first syllable in Devanagari to catch matra variants.
Vocabulary for specific domains
Legal: Indian legal terms mix Hindi, English, and Urdu. FIR (First Information Report), vakeel, adalat, rapat - these have standard spellings that AI may not know. Medical: Ayurvedic terms, Hindi medical vocabulary, and drug names need explicit inclusion. Tech: Indian startup ecosystem jargon (Series A, ARR, DAU) mixes with Hindi business terms.
For each domain, spend 5-10 minutes listing terms before the first transcription. This one-time investment pays off across all future recordings in that domain.
Frequently asked questions
Can I feed a vocabulary list to CapsAI before transcribing?
CapsAI does not currently accept custom vocabulary input before processing. The vocabulary list is for your review pass - it tells you what to search for and correct after the AI generates its draft.
How many terms should my vocabulary list include?
For a typical interview: 10-30 proper nouns. For a technical discussion: 20-50 terms. For a recurring series: the list grows over time but start with the most frequently mentioned names.
Should I include common Indian names in my list?
Only if the specific person uses an uncommon spelling. 'Rahul' and 'Priya' are common enough that AI handles them. But 'Rhea' vs 'Ria' or 'Aditya' vs 'Aaditya' warrant listing.
