WhatsApp is currently experimenting with a new update to Android beta users real-time voice chat modification enabled by Meta AI. This feature allows the parties to change their voices dynamically in the live discussions. The aspect marks the first direct integration of Meta AI into the core calling experience of WhatsApp. 

Highlights:

• WhatsApp beta introduces real-time voice chat modification using Meta AI.
• Android testers can dynamically alter their voices during live calls.
• Voice effect processing occurs primarily on-device for privacy.
• Users maintain control over activating these Meta AI voice chats features.
• This integrates Meta AI deeper into WhatsApp's communication tools.

It is an experimental feature (discovered in a recent android beta update) that alters voice calls in real-time even when the user is in an active call. By taking advantage of the Meta AI voice chats tech, the users can choose to implement several voice filters or effects to the speech and have them immediately alter their spoken output. The aspect goes beyond the pre-recording feature.

One of the main considerations is privacy. The effects on these Meta AI voice chats are intended to be processed on the device of the user. Such on-device technique reduces the exchange of data and is compliant with the security policies of WhatsApp regarding calls. The need for user control on feature activation is basic.

The addition is indicative of WhatsApp continuing to bring Meta AI functionality more deeply into its real-time communication. These Meta AI voice chats are aimed at improving real-time voice uses in the system. This is after introducing previously AI features such as chatbots in the app.
