ChatGPT Voice (OpenAI Help Center)

OpenAI, OpenAI Help Center, 2026

Read on October 17, 2026

What it is: OpenAI help article that separates ChatGPT Voice, a spoken conversation, from ChatGPT Dictation, which turns one recording into text you can edit before sending. It has a FAQ on when to use each and why transcripts may differ from speech.
How much weight it carries: Official OpenAI documentation. We read an archived copy because the live help center refused automated requests on the day we checked, so the archive date is unknown and the wording may have changed since. It does not name the dictation model or where audio is processed.
