Bangla first

It sounds like Dhaka, not like a translation.

Most voice AI treats Bangla as an afterthought. Kothon is tuned on Bangla speech, numbers, names and the English words people mix in every sentence.

Prices, dates and phone numbers read the way people say them
Mixed Bangla and English handled in one breath
Callers can interrupt without breaking the conversation
How it works

From idea to live calls in an afternoon.

1

Teach the agent

Add prices, hours and common questions. Describe the goal and tone in plain language.

2

Connect a line

Add your phone credentials, test the connection and give the agent a number.

3

Go live

Take calls, launch campaigns or call from your website. Read every transcript and summary.

Voices

Choose the voice for each conversation.

Pick the quality per agent. If one engine is unavailable, the call continues on the next without a break.

FAQ

Questions, answered.

Do I need numbers from Kothon?

No. Connect the phone provider you already use and keep your numbers and rates.

Does the caller know it is an AI?

You choose the wording. A short disclosure at the start is on by default.

Can it call a list of numbers?

Yes. Upload a CSV, describe the goal, set the calling window, and review results per contact.

What if the agent cannot help?

It follows your hand-over rules: transfer, forward, callback task, or a summary to your team.
