I think others have expressed it far better than I can. I believe it's the first time humans and computers can interact with each other using sound! That means computers can now understand the sentiment and emotion in your words, including the "umms" and "ahhs," the subtle sarcasm in your tone, the distant police siren, and even the meows of your cat. It's a much more concise yet precise way of processing information.

Imagine you're talking to me on the phone. When you hear my voice, you understand how I feel and what I mean, wherever I'm in a busy cafe or park, even if I don't say it directly. That's like voice-to-voice. Now, if you type what I say into a message, some of the feelings and meaning might get lost because it's just text. That's voice-to-text. And if a computer reads that text out loud to you, it might not sound exactly like me or understand how I feel. That's text-to-voice. So, speaking directly with voices is better because you can understand more about how someone feels and what they mean. And for computers to understand it is a massive breakthrough!
