Key Takeaways
- 1A 3-second API delay on cold calls creates an immediate 41% hang-up rate.
- 2Swapping legacy wrappers for direct WebRTC connections cuts latency to milliseconds.
- 3Raw API speed eliminates the need to pay for filler words like 'umm' and 'ahh'.
The breaking point: 41% of connected calls were terminated by the prospect within the first 5 seconds. The operation was paying per minute just to get hung up on.
**Action Plan:** Audit your current AI voice agent's Time to First Byte (TTFB). Record a test call and measure the exact milliseconds between you saying 'Hello' and the agent responding. If it is over 800ms, your prospects are already thinking about hanging up. You can measure this today without hiring an engineer.
Frequently Asked Questions
Why do AI voice agents have a delay before speaking?
Most AI voice agents rely on conversational wrappers that act as middlemen between the telephony provider (like Twilio) and the LLM. Processing audio, converting it to text, generating a response, and converting it back to audio causes compounding latency.
How do you eliminate AI voice latency?
By bypassing legacy wrappers entirely and using a direct WebRTC connection from your telephony provider to high-speed endpoints like OpenAI's GPT-5.6 Sol Ultrafast mode.
