OpenAI has introduced a new Advanced Voice Mode (AVM) for ChatGPT, enabling the AI to sing with capabilities likened to an opera singer. Users report that ChatGPT can now perform vocal tasks including singing, mimicking accents, and delivering emotionally expressive bedtime stories. This development marks a notable enhancement in ChatGPT's voice functionalities, with some users anticipating further improvements in the upcoming GPT-5 iteration. The singing ability appears to depend on the selected voice within the AVM, and while the quality varies, it represents a step forward in AI performance and vocal interaction.
