Voice AI
Live answering and AI callbacks—real-time, natural conversations
Overview
ResponseBud offers two voice AI features: live answering and AI voice callback. Both use a single real-time pipeline for natural speech recognition and synthesis.
Live Voice Answering
AI answers incoming calls in real time with natural conversation—one pipeline for listening and speaking.
- Answers calls immediately when they come in
- Natural, conversational AI interactions
- Available on Business+ plans
AI Voice Callback
AI automatically calls back customers who miss your call, ensuring no lead goes unanswered.
- Triggers after missed calls (no-answer, busy, failed)
- Configurable delay and max attempts
- Available on Pro+ plans
AI Voice Callback
When a customer misses your call, ResponseBud can automatically call them back using AI. This ensures you never lose a lead due to a missed connection.
Configuration Options
- Enable AI Voice Callback: Toggle this feature on or off
- Callback Delay (minutes): How long to wait before calling back (default: 2 minutes)
- Maximum Callback Attempts: How many times to try calling back (default: 1)
- AI Voice: Choose your voice in Settings → Voice (multiple options available)
- Human Escalation Phone: Optional phone number to transfer calls to a human (E.164 format: +1234567890)
When Callbacks Trigger
Callbacks are automatically triggered when:
- • A call is missed (no answer)
- • A call is busy
- • A call fails to connect
- • The customer hasn't opted out of callbacks
Live Voice Answering
Enable AI to answer incoming calls in real time with natural conversation. One pipeline handles both listening and speaking—ideal for 24/7 availability without extra staff.
How It Works
- Customer calls your Twilio phone number
- AI answers the call immediately (if enabled)
- AI has a natural conversation with the customer
- AI can collect information, answer questions, and schedule appointments
- If needed, AI can transfer to a human agent
Plan Requirements
Live Voice Answering is available on Business+ plans. If you're using Twilio (optional but recommended), make sure your Twilio webhook is configured to point to ResponseBud's incoming call endpoint.
Voice options
Live answering and AI callbacks use the same real-time voice pipeline. In Settings → Voice you can choose your preferred voice and configure escalation, hours, and greeting.
