Hi support team! I have noticed that when someone uses my voice assistant on my website from a mobile device the first assisant message is cut. The first part is simply not included. This problem become even worse when the user is wearing bluetooth headphones. I am using the web SDK. At first I thought it was a problem on my end, however after going to Vapi's homepage I now see that Vapi has the same issue. When you access vapi.ai on mobile the first words of the message is cut off. This is even worse if I wear bluetooth headphones. So the issue seems to be in the SDK itself. So basically the first message on www.vapi.ai is spoken like this: Desktop: "Welcome to Vapi. I am an assistant that you can talk to like a person, so how is your day going?" Mobile: "... Vapi. I am an assistant that you can talk to like a person, so how is your day going? Mobile + Bluetooth: "...assistant that you can talk to like a person, so how is your day going? Basically the first message becomes cut, which leaves a bad first impression for the users. It would be great if you could correct this issue. Both for me and for you guys 🙂 Thanks in advance!

Add a 200–300ms silence before the first message or delay playback slightly to prevent audio from being cut off on mobile..

But I am not having an audio file. I have a text I add in the dashboard that the assistant is supposed to speak at the beginning of the call. Vapi’s own website has the same issue so it would just be easier for you to fix it than for me to have to create audio files for mobile/desktop.

Hey Williham, I wanted to let you know that we're managing a high volume of support requests at the moment, so our response time might be a bit slower than usual. I truly appreciate your understanding and will get back to you as soon as possible!  Thanks again for your patience!

Hey there, I just wanted to add that I'm experiencing the exact same problem and it would be nice to have a resolution!

Set "startSpeakingPlan": { "waitSeconds": 0.5 } to delay speech and prevent the first words from being cut..

i have this same issue on my agents and would love to have a solution. The Start Speaking options don't solve it for me. I'm using a preset text message and invariably the first word or two gets clipped. So if it's "thank you for calling..." the customer hear "..you for calling"

Increase responseDelaySeconds to about 1s and silenceTimeoutSeconds to around 5s in Vapi to prevent first-word clipping..
