We’re rolling out a new speech-to-text model for dictation in ChatGPT across all plans. This is a behind-the-scenes update, so there are no changes to how you use dictation.The update improves transcription accuracy across languages and accents, including when multilingual speakers mix or switch between languages. Evaluations showed gains in Japanese, Korean, Chinese, Urdu, Vietnamese, accented English, and long-form Spanish, French, Italian, and Portuguese.Dictation is also more robust in noisy public spaces and workplace environments, with quiet or whispered speech, and when transcribing combinations of letters and numbers.In our ChatGPT dictation evaluations, word error rate—a standard measure of transcription accuracy—was at least 10% lower for top languages tested than with the previous production model.
