Background noise on phone calls: what to do when you can’t hear the caller
Sado AI team · · 4 min read
In short
Background noise on a call (a bazaar, a car, wind, speakerphone or office chatter) mostly breaks numbers, times and addresses. Three rules help: if you didn’t catch it, ask again instead of guessing; read important details back and get a yes; if the noise is too strong, agree a callback at a better time. On the operator’s side you need a quiet spot and a good headset. Test an AI operator from a noisy place too, and check in the transcript what it heard.
What noise breaks on a call
A phone line carries only a narrow band of sound. When it’s noisy, short words and word endings go first: in Uzbek, «besh yuz» (five hundred) and «besh ming» (five thousand), or the names Dilshod and Dilshoda, start to sound alike.
The real danger is that a misheard detail gets written down silently. A phone number with one wrong digit, a booking on the wrong day or the wrong district, and the customer is lost without anyone noticing.
Where noise comes from and what to do
| Noise | How you notice it | What to do |
|---|---|---|
| Bazaar, street, wedding | Many voices, music | Ask short questions, read key details back |
| Car, wind | Rumble, sentences cut off | Offer to call back once they’ve stopped |
| Speakerphone, Bluetooth | Echo, a distant voice | Ask them to hold the phone to their ear |
| Bad signal: basement, lift | Speech breaks up, silences | Say where you lost them; ask for the address by text if needed |
| Your own office | Colleagues talking behind you | A headset and a separate spot |
When you can’t hear the caller: ask again and confirm
- Don’t guess. Say it plainly: “Sorry, I didn’t catch that. Could you say it once more?”
- Ask in parts: the number in groups, the address as district, street and landmark.
- Read it back: “Ninety-four, six-one-two, twenty-three, forty, is that right?”
- Confirm the time with the weekday: “Thursday at three.” “Tomorrow” is easy to mishear on a noisy line.
- If two tries fail, suggest moving somewhere quieter or calling back at a time that suits them.
Sado: Assalomu alaykum, Baraka furniture, Shohruh speaking.
Caller: Hello… a sofa… do you deliver… how much?
Sado: Sorry, it’s noisy where you are. You’re asking about delivery for a sofa?
Caller: Yes, yes. To Sergeli.
Sado: Delivery to Sergeli is 80,000 so‘m. Shall I take your name and number?
Caller: Jasur. The number is ninety-four, six-one-two, twenty-three, forty.
Sado: Jasur, ninety-four, six-one-two, twenty-three, forty, is that right?
Caller: Right. Call me when I’m home and we’ll talk.
The company, price and number in this call are only an example.
Noise on the operator’s side
You can’t control the caller’s noise, but you can control yours:
- Use a headset with the microphone near the mouth; never take calls on speaker.
- A noise-cancelling headset matters most in an open office.
- Turn off music and TV, and seat people who make calls away from each other.
- Speak clearer and slower, not louder: a loud voice distorts on a noisy line too.
How to test an AI operator on a noisy line
A voice bot also hears worse on a noisy line, so test it in real conditions, not a quiet room: call from a bazaar or a car, switch on speakerphone, give your number in groups and an address with a landmark. Then open the recording and full transcript in the portal: you see at once what the operator heard and what it wrote down.
Sado’s AI operator that speaks Uzbek waits until you finish a number, stops and listens when you interrupt, and doesn’t make up what it doesn’t know. If a caller says “call me later”, it calls back at that time on its own. Ask for a read-back rule for key details to be put in the script during setup. More checks: testing a voice bot in Uzbek and Russian.

Questions
Should I ask the caller to speak louder?
It rarely helps: when the caller speaks louder, the noise around them gets louder too. Ask them to hold the phone to their ear or move somewhere quieter.
How do I catch a number written down wrong because of noise?
Read it back and count the digits: an Uzbek number with its code has nine digits, for example 90 123 45 67. Too many or too few means ask again.
How do I know an AI operator misheard something?
Every conversation’s recording and full transcript are kept in the portal. Compare the text with the recording to see what the operator heard and what it wrote.
