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.

​
Connecting to VAPI

1

Create a VAPI Account

Start by creating an account on VAPI. It’s a straightforward process - simply head over to VAPI’s website.

We love VAPI. For more detailed information, check out their documentation.

2

Create an Assistant

Once your account is set up, create an assistant on VAPI:

  • Choose from various voice providers (e.g., Elevenlabs, Cartesia, OpenAI)
  • Select a voice that fits your agent’s persona (For instance, our agent Gia uses the “Hannah” voice from Cartesia)
  • Craft a well-formatted system prompt.

Obtain API Keys from VAPI

After setting up your assistant:

  1. Navigate to your profile in the left-hand corner

  2. Go to API keys

  3. Copy both your private and public keys

Configure TIXAE Agent Credentials

In TIXAE Dashboard:
