OpenAI’s next‑gen audio models slash errors and add voice‑style control
OpenAI rolled out new speech‑to‑text (gpt‑4o‑transcribe, gpt‑4o‑mini‑transcribe) and text‑to‑speech models that cut word‑error rates and let developers dictate vocal style (e.g., sympathetic, medieval). The upgrades target noisy, accented speech and enable highly customized voice agents, boosting reliability for call‑centers, meetings, and creative narration.
