Uzbek and Russian voice bots: what is hard, and how to test the quality

Why an Uzbek phone call is hard for a bot

• Mixed languages: “Ertaga zakaz bersam, dostavka bo‘ladimi?” (“If I order tomorrow, is there delivery?”) uses Uzbek and Russian words in one sentence.
• Numbers: people dictate a phone number in groups, “ninety-one, five hundred twelve, forty-five, sixty-seven”, and say prices like “one and a half million”.
• Addresses and landmarks: “Chilanzar, ninth block, behind the bazaar”.
• Names: Dilshod, Shahzoda, Abdurahmon, which then have to be spelled correctly in the CRM.
• Accents and dialects: every region speaks a little differently, and many people talk fast.
• The phone line: only a narrow band of sound gets through, there is background noise, some people use speakerphone.
• Interruptions: the customer adds something while the operator is talking, or changes the question.

That is why a nice voice sample on a website proves nothing yet. What matters is what happens on a real call.

What a good voice operator gets right

• It answers in the caller’s language. Sado speaks whichever language the caller uses. When Russian words slip into Uzbek speech, the conversation stays in Uzbek. When the caller asks “Переведи на русский” or “o‘zbekcha gapiring”, or keeps speaking the other language for several sentences, it switches.
• It stops when interrupted: when the customer starts talking, the operator stops, listens and answers the new question.
• It waits for the whole number: if you dictate a phone number in groups, it doesn’t jump in after the first group.
• It doesn’t make things up: if the answer isn’t in its information, it says a manager will call back and creates a task.
• It keeps it short: one or two sentences and a question, not a lecture.
• A natural voice: Sado has two voices, Malika (female) and Shohruh (male). Listen to them on the home page.

Before you choose: 10 tests

1. 1Call from a real phone, not only the website demo: sound on a phone line is different.
2. 2Ask the 3–5 questions your customers ask most and check the answers match your company’s information.
3. 3Ask for a price and have it work out a total: “What if I take three?”
4. 4Dictate your phone number in groups and check it was written down correctly.
5. 5Give an address with a landmark.
6. 6Give your first and last name, then see how they were written in the portal or CRM.
7. 7Mix Uzbek and Russian words, then ask it to switch: “по-русски, пожалуйста”.
8. 8Interrupt the operator while it is talking: it should stop and listen.
9. 9Ask something that isn’t in its information: it should not invent an answer.
10. 10Ask “Are you a robot?”: it should not pretend to be human.

After each test call, read the recording and transcript: what the operator heard and what it answered. Make one call from a noisy place too.

Voice operators vs text-to-speech services

Searching for “Uzbek voice” mostly turns up text-to-speech (TTS) or speech recognition services. Those are building blocks. Answering a phone call takes the whole chain: recognising speech, understanding it, putting an answer together from the company’s information, saying it in a natural voice, connecting to the phone line and writing the result to the CRM.

Sado is that whole chain in one service: you only connect your number and set up the operator. How it works: what is an AI voice operator.
