OpenAI just dropped a massive release: new speech-to-text and text-to-speech models are now live in the API. Here’s what this means for Voice AI devs and builders like us: 🎙️ Ultra-accurate speech-to-text The new gpt-4o-transcribe and gpt-4o-mini-transcribe models drastically improve transcription accuracy—especially in noisy environments and across different languages. That’s a game-changer for real-world use. 🗣️ Customizable text-to-speech with STYLE With gpt-4o-mini-tts, you can now instruct the voice on how to speak—like “sound like a warm, confident concierge” or “be direct and urgent.” The level of control here is insane and unlocks true voice persona design. ⚙️ What this unlocks: • More emotive, human-sounding voice agents • Better agent-to-human interaction quality • Personalized brand voice experiences at scale • Serious improvements to call center automation, outreach, and receptionist flows 💥This is a whole new playing field and This is YOUR MOMENT to start experimenting and pushing the limits! We'll be sharing examples, experiments, and integration tips in the coming days. If you’re planning to build something with this or have questions—drop them below! ⬇️ Let’s gooo 🚀

Hi all, I would like some help or a nudge in the right direction with an issue I encountered while setting up my very first Vapi assistant. I have created a reception to answer questions, etc. So far, on a basic level of knowledge, it is working fine. After I configured the prompts properly, the first call was working totally fine. There are no big issues besides some inaccuracies that can be fixed in the future. Long story short, when I tried to call the agent again to test some other questions, the agent hung up the call after the initial greeting. When I looked into the logs, the transcriber did register my voice as it was transcribed, yet the assistant thanked me for the call and ended it. This happened multiple times. After searching the Vapi KB, it was suggested that the End call function be turned off, which solved the issue of the call ending prematurely. But it presented another one, which will not end now unless the caller hangs up. Has anyone encountered the same issue, and if you did, how were you able to solve it? Thank you
