OpenAI said on the 16th that it updated ChatGPT's voice conversation feature, Voice. By applying a new voice model, GPT-Live-1.1, it improved intonation and vocal expression in multiple languages, and according to OpenAI, Korean conversation has also become more natural.

Two new Korean voices were added, named Hanul and Haetsal. According to Industry News, the update is rolling out worldwide in stages. IT Chosun reported that the voice feature was tweaked so conversation can continue even while the assistant searches for information.
