Voice Broadcasting
Send pre-recorded voice messages to thousands of recipients simultaneously. Trigger campaigns via API using say@v2 with TTS or audio files. Real-time delivery tracking, response capture via gather@v2, and automated retry management.
Overview
Voice Broadcasting lets you deliver the same voice message — pre-recorded audio or text-to-speech — to a large list of recipients in parallel. Callr handles the dialing, delivery, retries, and reporting.
How it works
Build a call flow using say@v2 to play your message. Optionally add gather@v2 to capture recipient responses (press 1 to confirm, press 2 to opt out). Trigger the campaign via the REST API with your recipient list. Callr dials in parallel, respects rate limits, and retries unanswered calls on your schedule.
Use cases
Emergency alerts and public safety notifications. Appointment reminders for healthcare and service businesses. Delivery notifications for logistics. Promotional campaigns with opt-in response capture.
