On initial greeting, the first 1-3 words are cut off. For example, if the greeting is "Hi, this is Bob. How can I help you?", in production over the phone it'll say "is Bob. How can we help you?". Any way to add a delay to the greeting, increase the number of rings etc.?

Hi there, Thank you for your message. Our team is currently out of the office. We operate Monday through Friday, from 9:00 AM to 8:00 PM Pacific Standard Time (PST). We’ll get back to you as soon as possible during our normal business hours. If your message is urgent, please mark it accordingly or include “URGENT” in the subject line, and we’ll do our best to respond promptly. Warm regards, Vapi Customer Support Team

To prevent your assistant's greeting from being cut off, add a short delay before the greeting starts by setting the

waitSeconds

parameter in your

startSpeakingPlan

. For example:

json
"startSpeakingPlan": {
  "waitSeconds": 0.7
}

This will add a 0.7-second pause before the assistant begins speaking, helping ensure the full greeting is heard. Note: Adjust the value as needed for your use case.

We are facing a similar issue on the SDK. Every time a call is started, the agent is interrupted by its own echo. This is happening in almost 60-70% of the calls. Any fix for this?

Thank you for sharing the details. To help diagnose the echo issue in your SDK calls, could you specify which SDK (language and version) you are using and whether the echo occurs on both ends of the call or only for the assistant?

It’s happening only for the assistant. Since the echo happens the call just goes weird

waitSeconds doesn't do anything for the greeting.

@Satyen did you solve this? experiencing the same

Hey! Could you share a call ID where this happened? That’ll help us take a closer look. One thing to note: there can sometimes be latency on the phone service provider side right when the call is answered. We only connect the assistant once the call connection is fully established, so if the provider takes a moment to stabilize the audio stream, the very beginning of the greeting can get clipped. Once we have a call ID, we can confirm whether that’s what’s happening in your case.
