WhatsApp does not have a built-in feature to directly play voice notes through the phone's earpiece or speaker during a call. When you receive a voice note while on a call, it typically plays through the same audio output that your call is using, which would be your phone's earpiece if you are not using headphones.
Here's how you can listen to a voice note during a WhatsApp call without using headphones:
Switch to Speakerphone Mode (if needed): During the call, you can switch to the speakerphone mode on your phone. This will make the audio output louder, and you'll be able to hear the voice note more clearly.
Pause the Call (Android Only): If you're using an Android phone, during a WhatsApp call, you may receive a notification for the voice note. Drag down the notification shade and pause the call from the notification area. Then, play the voice note from the WhatsApp notification. After listening to the voice note, you can resume the call from the notification area again.
Use Call Waiting (iOS Only): If you're using an iPhone, you can enable Call Waiting in the Settings app > Phone > Call Waiting. With Call Waiting enabled, you will be able to receive WhatsApp voice notes as notifications during a call. You can then switch to the notification and listen to the voice note.
Keep in mind that WhatsApp frequently updates its features, so the behavior might have changed . Always make sure you have the latest version of WhatsApp from the app store to access the latest features and improvements. Also, different phone models and software versions may have slightly different options and behaviors.
If playing voice notes during a call without using headphones is not possible with the standard WhatsApp app, you may need to explore alternative WhatsApp mods or third-party apps that offer additional functionalities. However, be cautious when using third-party apps, as they may violate WhatsApp's terms of service and could potentially pose security risks.
