Frequently asked questions

Why does speech-to-text write English words in Hindi script?

On mixed Hindi-English audio, a speech-to-text model set up for Hindi may transcribe English words and acronyms in Devanagari, for example writing 'TGT' as 'टीजीटी'. The words are heard correctly but written in a different script.

How does that break lead qualification?

If your agent or your post-call rules look for the English string 'TGT', 'B.Ed' or 'EMI', they miss the Devanagari version, so qualified people are marked unqualified.

How do you fix keyword checks on Hinglish calls?

Match meaning, not strings. Ask the LLM to judge whether the person mentioned a designation or qualification in any script, list both spellings in instructions, and test with real recordings before relying on the result.

Should I switch to English-only transcription?

Usually not. English-only transcription handles the Hindi parts of the call worse. Keep the language setting that fits your callers and make your checks script-aware.

How can I catch this problem early?

Read the transcripts of your first 20-30 calls, not just the summaries. If key terms appear in Devanagari, review every rule that depends on them.
