Tenglish is the normal case
Tenglish, the mix of Telugu and English, is how many Telugu speakers talk on a business call. The rate, the appointment, the OTP and the delivery are said in English, and the rest stays Telugu. It is not an error to be fixed, and any system that treats it as one will struggle.
Where the failure happens
Most voice systems are built around one language per turn. When an English word lands inside a Telugu sentence, the recogniser either garbles the word or loses the sentence around it. The agent then answers the wrong question, or asks the caller to repeat.
Why it hurts more on numbers and names
The words most likely to be spoken in English are the ones that matter most: amounts, times, product names. Getting them wrong causes wrong bookings and wrong quotes, not just awkwardness. That is why confirmation of these details matters.
How to test for it
Do not read a clean Telugu script. Say a price and a time in English inside a Telugu sentence. Switch to English for a whole turn and back. Interrupt halfway. Then check the transcript and whether the agent confirmed the details you cared about.
What a good result looks like
The agent answers in the caller's mix without asking them to choose, repeats critical details back, recovers gracefully from a misheard word and keeps the transcript in both languages as spoken.
