In the era of advanced AI and Large Language Models (LLMs), voice interactions have reached unprecedented levels of naturalness. TIXAE Agent harnesses this technology by integrating with VAPI, a cutting-edge voice-to-voice platform, to provide your agents with lifelike conversational abilities.
Voice-to-voice technology now incorporates natural speech patterns, including filler words like “mhmm” and “ya”, making conversations feel more authentic. Users can even interrupt the AI mid-sentence, closely mimicking human-to-human interactions.
This guide will walk you through setting up your VAPI profile and enabling voice-to-voice capabilities for your TIXAE Agent.
