The Google Pixel Watch 2 allows you to answer incoming calls and initiate calls by staying connected to your smartphone via Bluetooth. Here are some important details:

- Call management: the Pixel Watch 2 supports call management directly from the watch. You can accept, reject or end calls, as well as start calls, as long as your smartphone is nearby and connected via Bluetooth.
- Speaker: The Pixel Watch 2 has a speaker that allows you to make calls directly from the watch. The speaker is loud enough to hold conversations in a normal environment, although the volume may not be sufficient in louder environments.

Overall, the Pixel Watch 2 should meet your call management and speaker volume needs as long as you have a stable Bluetooth connection with your smartphone.
