Reduce connection delay in iOS SDK for real-time voice assistant activation

[albertcyhe]

Hey team,

I’m using the Vapi iOS SDK to build a voice assistant, where the user can say something like “Hey” to trigger a connection to Vapi and handle tasks like explaining content. However, with the current SwiftUI version, I’m experiencing a delay of about 5-7 seconds from when I hit “start a call” to when it actually connects. This delay makes it tough to use for a real-time assistant scenario.

Is there a way to pre-load certain modules or make adjustments so that a quick action (like a tap or a “Hey” trigger) could start Vapi with minimal delay? Any tips or workarounds would be super helpful!

Unfortunately most of that is WebRTC setup. I see people having a workaround to play some sounds.

Daily team has it as a priority to shorten this time and I'll bump it up again.
