Understanding how Speako handles phone calls helps you optimize your AI agent's performance. This article explains the technology behind AI-powered calls.

Call Flow Overview

When a customer calls your Speako-connected phone number:

  1. Call Received — The call reaches Speako's phone system
  2. Greeting Played — Your customized greeting welcomes the caller
  3. Conversation Begins — The AI agent listens and responds naturally
  4. Actions Taken — The agent books appointments, answers questions, or performs other tasks
  5. Call Ends — The conversation wraps up with a farewell

Speech Recognition

The AI agent converts spoken words into text in real-time. This allows it to:

  • Understand different accents and speaking styles
  • Process natural conversational language
  • Handle interruptions and clarifications
  • Recognize names, dates, and numbers

Natural Language Understanding

Once speech is converted to text, the AI:

  • Identifies the caller's intent (booking, question, cancellation)
  • Extracts key information (dates, times, services)
  • Determines the appropriate response
  • Accesses your knowledge base for answers

Voice Synthesis

The AI agent responds using natural-sounding voice synthesis:

  • Multiple voice options (male, female, various accents)
  • Adjustable speech speed
  • Natural intonation and pacing
  • Custom pronunciation for specific words

Tool Execution

When the caller needs action, the AI agent uses tools:

  • Booking Tools — Check availability and create appointments
  • Customer Tools — Look up or create customer profiles
  • Knowledge Tools — Retrieve business information

Real-Time Processing

Everything happens in real-time:

  • Speech recognition: instantaneous
  • Understanding: milliseconds
  • Response generation: under a second
  • Voice synthesis: streams as text is generated This creates natural, flowing conversations without awkward pauses.
