One Campaign,A Different Sentence For Everyone
Voice broadcasting reads one recording to everybody. Dynamic TTS writes a line for each contact — their name, their balance, their appointment — and speaks it in Bengali. Survey calls go further and ask a question, collecting the answer as a keypress.
Two campaign types, one contact list
Both included with Professional, and both callable from your own system.
Dynamic TTS calls
Write one template with placeholders and every recipient hears their own version. Merge their name and any field you imported, or upload a data file that carries a finished sentence per phone number.
- Per-recipient variables
- Or one line per number from a data file
- Audio cached, so repeats cost nothing
Survey calls
Ask a series of questions and record which key each person pressed. The menu is spoken automatically from the options you define — no recording studio, no IVR to build.
- Ordered questions per campaign
- Menu spoken from your option labels
- Whole call recorded alongside answers
Bengali voices, not translations
Native Bangladeshi Bengali neural voices, with Indian Bengali and English available on the same campaign. The keypad prompt is generated in the same language as the question.
- bn-BD neural voices
- Bengali, English or Hindi prompts
- Male and female options
Callable from your own system
The Interactive Calls API places these calls from your software with an API key — one number or a CSV — and reports the outcome back.
- POST one call or a batch
- Status and outcome per call
- Included with Professional
From question to answer
Everything below happens on the call — nobody has to call back.
Write the questions
Each question gets its own keypad options — 1 for satisfied, 2 for not satisfied, and so on. Order them however you want to ask them.
The call speaks them
Each question is turned into speech with the option menu appended, in the language you chose. Nothing is pre-recorded, so editing a question needs no new audio.
The keypress is captured
One digit per question, stored with both the number pressed and what it meant, against that contact.
Read the results
Survey Results shows the answer distribution per question and the individual responses, with the call recording beside each one.
What people use them for
Payment reminders
Each customer hears their own outstanding amount and due date, instead of a generic notice they will ignore.
Appointment confirmation
Ask them to press 1 to confirm or 2 to reschedule, and get a list of both before the day starts.
Satisfaction surveys
Call after a delivery or a service visit and collect a score while the experience is still fresh.
Verification and notices
Reach thousands with a personalised message and know exactly who answered, who pressed what, and who never picked up.
