Send Voice Calls in Seconds: Automate TTS with ClickSend API

This n8n workflow enables instant text-to-speech (TTS) voice calls using the ClickSend API. Users submit a form with the message text (up to 600 chars), recipient phone number (with international prefix), voice gender (male/female), and language (e.g., en-us, it-it). The workflow triggers on form submission and sends a POST request to ClickSend's voice endpoint, converting text to speech and delivering it via automated call with machine detection.

Benefits include rapid deployment for notifications, reminders, alerts, or customer updates without manual dialing. It saves time, scales easily, and integrates seamlessly in n8n for broader automations like CRM triggers or event-based alerts. Ideal for businesses needing voice communication, such as appointment confirmations, security alerts, or marketing broadcasts.

Use cases: Healthcare for patient reminders, e-commerce for order updates, sales for lead follow-ups, or emergency services for urgent notifications. The workflow's simplicity allows quick customization, like adding error handling or multi-recipient support, making it a powerful tool for voice automation.
