Extract audio file mid call
Is there a way of saving an audio clip of the user's first few utterances on a call? This would be useful for voice biometrics, where a file needs to be sent to the API to verify it. Hope that makes sense.
AHi @geepayne, I'm an AI assistant for Vapi. I'll analyze available sources and get back to you shortly.

Sorry, I wasn't able to find any information about your question. You can get more help at Contact Us.
AGot it. Tagging @Vapi Team for additional help.
Lcall_id?
SNo, if possible to get an audio file of the first 5 or 10 seconds of the caller's words to send to the voice biometric API
SCurrently vapi only creates audio file at the end of the call. How can I get an audio file while the call is still live?
LActually, you can't get it. I think you are trying to build an authentication kinda of setup if I am not wrong or is it something different?
SYes exactly, it's for authentication using voice matching
SAny suggestions? Or is there a way to add another system to a live call to do the recording?
LI can provide a workaround, but it requires substantial coding knowledge. Whenever a call is triggered and you're subscribed to the webhook request, you receive a http://vapi.daily.co/ link. This link is where all the audio transmission occurs, so you can use it to capture the user's first 10 seconds of speech. I'm not entirely sure, but I believe this method could potentially fulfill your use case.
Please note, I haven't tested this with a phone call to confirm whether or not a daily.co link is included in that webhook request, so you'll need to verify this.

AThis is what the daily.co link looks like when the call is ongoing...
SHi @Sahil, can you shed more light on this now that we have the image above showing the daily.co link? What next steps would you suggest?
LI would write a script for a bot who will join daily.co and listen to the sound and will write some logic for it to record only first occurrence.
SHi @Sahil , there is a request for an Daily.co API key when trying to access the room. This will need to be Vapi's API key right? What should I use there?
LWhen you create a new Call the daily.co temporary link is there in the response object for which you don’t need to enter anything
AThe daily.co link works without any auth as I sent in the ScreenShot, we just need to find a way to record a sample of the person.
