OpenAI has introduced three new state-of-the-art audio models, significantly enhancing voice interaction capabilities. Notable features include the ability to instruct the TTS (text-to-speech) model not just on content but also on delivery style, enhancing user experience in applications like customer service and storytelling. Feedback indicates varying levels of satisfaction; while some users praise the customizability and cost-effectiveness, others highlight that the voice quality may still not meet human-like standards. Developers can now explore more nuanced prompt engineering to enrich audio outputs, and the Agent SDK's support for audio is seen as a major advancement.
