If your qualification depends on hearing a specific English word, check how it is written in the transcript. In one deployment, a CBSE exam-prep book publisher's agent looked for designations like PRT, TGT and PGT that genuine teachers mention unprompted. On a Hindi-English benchmark, the speech-to-text transcribed some of those acronyms in Devanagari. A check for the English string would have marked real teachers as unqualified. This post explains the problem and how to design around it.

What happens
A teacher says: "Main TGT hoon, Class 9 aur 10 ko science padhata hoon."
Depending on the language setting, the transcript may read:
- "Main TGT hoon..." (Latin script), or
- "मैं टीजीटी हूं..." (Devanagari), or a mix.
Both are correct transcriptions of what was said. The problem is anything downstream that expects one spelling.
Where it breaks
- Keyword rules in post-call extraction. "Qualified if the transcript contains TGT, PGT or B.Ed" silently fails.
- The agent's own logic. An instruction like "if the caller says TGT, skip the class question" may not fire.
- Reports and searches. Searching transcripts for "CTET" misses "सीटीईटी".
The same applies to other common English terms on Indian calls: EMI, KYC, OTP, GST, COD, PIN code, brand and product names.
How to design around it
- Judge meaning, not strings. Ask the extraction step "Did the person mention a teaching designation or qualification (in any script)? Which one?" instead of matching exact text. LLMs handle Devanagari and Latin spellings of the same acronym well when told to.
- List both spellings in instructions for the few terms that matter: "TGT (टीजीटी), PGT (पीजीटी), B.Ed (बीएड)".
- Don't make one keyword decisive. Use it as one signal alongside class, subject and how detailed the answer is.
- Keep the language setting that fits your callers. Switching to English-only transcription to fix acronyms usually makes the Hindi parts worse.
- Test with real audio. Record 20-30 real or realistic calls and read the raw transcripts before trusting any rule.
A quick audit checklist
- List every word or acronym your qualification or routing depends on.
- Search a day of transcripts for each, in both scripts.
- Rewrite exact-match rules as meaning-based questions.
- Re-check after any change to speech or language settings.
