OpenAI is enhancing text-based agents by introducing new speech-to-text and text-to-speech models in its API, enabling more intuitive and intelligent voice interactions. This advancement allows users to communicate with agents through natural spoken language, expanding their usefulness beyond text-based exchanges.
The latest speech-to-text models set a new industry benchmark for accuracy and reliability, especially in challenging conditions like accents, background noise, and variable speech speeds. These improvements make the models ideal for applications such as customer call centers, meeting transcriptions, and other environments requiring precise audio processing.
For the first time, developers can instruct the text-to-speech model to adopt specific tones and styles—for example, “talk like a sympathetic customer service agent.” This customization opens new possibilities for personalized voice agents, enabling empathetic customer interactions or expressive storytelling across industries.
Since launching the first audio model in 2022, OpenAI has continuously improved model intelligence, accuracy, and performance. These new audio models empower developers to build robust speech-to-text systems and dynamic text-to-speech voices, offering greater versatility and enhanced user experiences.
With these advancements, OpenAI is paving the way for smarter, more adaptable voice agents, improving both practical applications and creative possibilities in real-world use cases
