What is OBD (Outbound Dialing)?

OBD stands for Outbound Dialing — the system automatically places outgoing calls from a contact list and plays a voice message or IVR menu. Textspeed's OBD platform dials at scale, applies smart retries, and reports results in real time.

What's the difference between voice broadcasting and IVR?

Voice broadcasting pushes a message out to many people at once. IVR adds interaction — the recipient hears menu options and presses keys, such as 'press 1 to confirm.' Textspeed combines both, broadcasting a message and capturing keypress responses in the same call.

Can I send voice calls using text-to-speech in Indian languages?

Yes. You can upload a recorded audio file or type your message and let text-to-speech voice it in 22+ Indian and international languages, so campaigns can be personalized and localized without a studio.

Can I capture customer responses (press 1 / DTMF)?

Yes. With IVR and DTMF capture, customers respond by pressing keys on their keypad, letting businesses confirm appointments, run surveys, qualify leads, or transfer the call to a live agent — every keypress is logged in reports.

Do you provide a voice call API?

Yes. Textspeed offers a voice/OBD API to trigger calls, IVR flows and retries directly from an app, CRM or workflow, and receive delivery, connect and keypress data via webhooks.
