Can the Genesys Cloud WebRTC phone alert use my computer speakers but the call conversation use my headset?

Yes. Genesys Cloud sends alerts, such as incoming calls, to your default computer audio. The Genesys Cloud WebRTC phone sends call audio to the speakers of your choice. To choose default audio devices for your computer, use your computer’s controls. To change the audio devices used during a web-based phone call, use the phone settings found where you select the Genesys Cloud WebRTC phone as your phone.
