What is Voice AI?

Voice AI refers to artificial intelligence systems that can understand spoken language, process user intent, and respond using realistic, human-like speech.

A modern Voice AI solution combines three technologies:

• Speech-to-Text (STT)
• Large Language Models (LLMs)
• Text-to-Speech (TTS)

Together, these technologies allow businesses to create intelligent voice assistants capable of handling real conversations.
