The Anatomy of Modern AI Phone Agent Providers
What “AI Phone Agent” Really Means in 2025
At its core, an AI phone agent stitches together four engines: automatic speech recognition (ASR), a natural-language understanding (NLU) brain, dialog management with guard-rails, and text-to-speech (TTS). Layer on real-time sentiment analysis and secure telephony APIs, and you have a virtual rep that never sleeps, scales elastically, and—done right—delights callers.

Usage-based (per minute or per interaction): Ideal for seasonal call volumes; Twilio and Replicant excel here.
