Slack Notifications → Generate Voice Alerts → Send via WhatsApp
Create personalized voice notifications for critical Slack messages and deliver them instantly via WhatsApp, ideal for remote teams and executives who need immediate audio alerts.
Workflow Steps
Zapier
Monitor Slack for keywords
Create a Zapier trigger that monitors specific Slack channels for urgent keywords like 'CRITICAL', '@everyone', or specific project names. Set up filters to only capture high-priority messages that require immediate attention.
Mistral Speech Model
Convert message to speech
Send the Slack message content to Mistral's speech model via API. Configure the voice to be clear and urgent. Since the model runs on mobile devices, it can generate audio quickly without server delays, perfect for real-time alerts.
Twilio
Process audio for messaging
Use Twilio's API to format the generated audio file for WhatsApp delivery. Ensure the audio meets WhatsApp's file size and format requirements (under 16MB, MP3/AAC format).
WhatsApp Business API
Send voice message
Deliver the voice message to designated WhatsApp numbers or groups. Include a text preview of the original Slack message for context. Set up delivery confirmations to ensure the alert was received.
