How to using Cloud IoT core for device (IoT record sound) and save to cloud storage?

Question

I'm a new user of the GCP and still learning. I want to ask about the concept of Cloud IoT core. So I want to make a project where an IoT device can record sound, then can send the sound to cloud storage. Can it be done using the Cloud IoT core to store sound files (.wav / mp4 / etc)? And please give me some information on how Cloud IoT core works to save sound files from IoT devices to a storage bucket?. I've read other references, but I'm still a little confused about what to do. Thank you

Concept of Cloud IOT core:

https://cloud.google.com/iot/docs/concepts/overview.

There is no clear reference available on "How Cloud IoT core works to save sound files from IoT devices to a storage bucket" ,I have compiled from several documentations and here is the possible solution:

Cloud IOT core receives sound files from IOT devices,Telemetry data is then forwarded to pubsub topic .[1]You can then use cloud functions to trigger API calls such as Speech to text and store it in GCS.

If you do not stick to these limits and quotas, it could be hardly possible.

I think you can provide a better solution with http/s api.
