Vendor / paper demo

2-speaker demo (Speaker 1 + Speaker 2) · Official VibeVoice project-page 2-speaker demo (2p_argument.mp3) with the published timestamp transcript.

Speaker 1: I can't believe you did it again. I waited for two hours. Two hours! Not a single call, not a text. Do you have any idea how embarrassing that was, just sitting there alone? Speaker 2: Look, I know, I'm sorry, alright? Work was a complete nightmare. My boss dropped a critical deadline on me at the last minute. I didn't even have a second to breathe, let alone check my phone. Speaker 1: A nightmare? That's the same excuse you used last time. I'm starting to think you just don't care. It's easier to say 'work was crazy' than to just admit that I'm not a priority for you anymore. Speaker 2: That's not fair! Of course you're a priority. You think I enjoyed being stuck in that office, drowning in spreadsheets, while knowing I was letting you down? It was stressful and I felt terrible. Speaker 1: I just... I was really looking forward to tonight. I've had a rough week and I just wanted to see you. When you don't show, it doesn't just feel like a broken plan, it feels like I don't matter. Speaker 2: You're right. It's not fair to you. There's no excuse. I should have found a way to let you know, even if it was just a thirty-second call. I messed up. I'm really, truly sorry. How can I make it up to you?
