Two huge voice AI breakthroughs just dropped: OpenAI's GPT Realtime 2 and Thinking Machines' new "interaction models" from former OpenAI CTO Mira Murati. AI voice is crossing the chasm from reactive dictation to proactive, real-time conversation — and that means voice is becoming a full marketing channel. In this episode, Kipp breaks down what happened, shows the live demos, and gives you the framework for making sure your brand sounds right when customers start hearing it everywhere.
📌 WHAT WE COVER:
→ OpenAI's GPT Realtime 2 voice upgrade — what changed
→ Thinking Machines' full-duplex AI that interrupts you mid-sentence
→ Why voice is becoming a marketing channel, not just a tech feature
→ The "call your own company" audit every marketer should do today
→ How to build a custom brand voice with ElevenLabs and other tools
→ Why leaving voice to your IT team is a marketing trap
→ Custom instructions and system prompts for voice agents
→ Sesame AI demo — what emotive, brand-aligned voice AI sounds like
