Bangla AI voice costs: 30 seconds, one minute, and ten minutes
Understand Kontho credits, quality settings, writing charges, one-time packs, and the free download conditions.
In this guide
Kontho charges 1 credit per second of Fast audio and 2 credits per second of High quality audio. Exactly 30 seconds of Fast audio uses 30 credits; one minute uses 60; ten minutes uses 600. Final charges follow generated duration, which can differ from the estimate.
Standard packs
These are list prices, excluding temporary offers. Check current pricing and checkout before buying.
| Pack | Standard price | Credits | Fast audio only |
|---|---|---|---|
| Starter | BDT 99 | 600 | 10 minutes |
| Creator | BDT 399 | 3,600 | 60 minutes |
| Pro | BDT 999 | 10,800 | 180 minutes |
Packs are one-time purchases, not monthly subscriptions. High quality buys half the duration from the same balance. At standard prices, a Fast minute represents BDT 9.90, 6.65, or 5.55 respectively. This is a pack-rate calculation, not a separate per-minute invoice.
Include writing and repeat generation
Short, medium, and long writing requests use 10, 20, and 40 credits. A Reels kit uses 40. One kit followed by exactly 30 seconds of Fast audio uses 70 credits. Additional generations spend additional credits.
Proofread names, prices, and dates before generating. Test a few lines before committing a long script.
Free allowance and downloads
The normal trial grants 300 credits after the first email or phone verification and another 300 after both are verified, subject to eligibility controls. You can preview generated audio and claim one free download of up to one minute. Other downloads need a purchase of any pack.
Creating an own-voice clone does not deduct wallet credits; generating its speech does. Credits never expire, but generated audio is retained for 30 days. Save important authorized files locally.
Checkout currently uses shurjoPay and requires a Bangladeshi mobile number. Check available payment methods and country requirements rather than assuming international access. Start with the pronunciation guide, then choose a pack from your expected real usage.
