What people are saying
Kothon is used by creators, teachers, and developers across Bangladesh. Here’s a handful of notes from the people using it every day.
Cloned my own voice in ten seconds — now my audiobook narrates itself while I sleep.
The only TTS that gets Bangla numbers and English code-switching right. “৳১,৫০০” sounds perfect.
Our kids' learning app shipped with Kothon. The students think a real teacher is talking.
Sylheti dialect support sold me. My parents finally use our app without complaining.
Replaced our paid cloud TTS in an afternoon. WAV export and local voice profiles — exactly what we needed.
Record, name the profile, pick it from the dropdown. My students do the whole flow themselves.
In-app playback plus save-as-WAV makes editing podcast intros effortless.
Runs great on my old laptop. No subscriptions, no per-character fees — just works.
Better than most other paid Bangla voices out there, and it stays on my machine.
