OpenAI officially launched GPT-4o real-time voice mode for all users in June 2026, ending its previous limited beta phase. The update allows ChatGPT to respond in natural spoken language with human-like tone, emotion, and pacing. Free users get 15 minutes of voice conversation per day, while Plus subscribers receive unlimited access. The rollout follows months of testing and marks a significant milestone in consumer AI interaction. Early users report noticeably improved response times and more natural conversational flow compared to the previous voice features.
