OpenAI says 250 million people use ChatGPT’s Voice or Dictation features each week, about one-fifth of its reported 1.2 billion weekly users as of September 29, 2026.

Those figures come from OpenAI and have not been independently verified, so they should be treated as the company’s own account rather than audited counts.

The combined Voice and Dictation audience grew from more than 150 million weekly users on July 8, 2026, when OpenAI launched GPT-Live and made full-duplex voice the default, allowing users to speak and listen simultaneously.

Voice supports spoken conversations with ChatGPT, while Dictation turns speech into editable text; voice can be useful hands-free, such as while commuting, and for language practice.

ChatGPT’s overall reported weekly audience rose from 900 million in February 2026 to more than 1 billion in August and 1.2 billion by September 29; OpenAI had also reported more than 50 million consumer subscribers in February.

Earlier figures, including OpenAI’s report of more than 250 million weekly ChatGPT users on October 2, 2024, measured overall service use and do not show how many people used Voice or Dictation.

As voice adoption grows, reliability matters more because delays and errors are especially noticeable in spoken interactions; future user totals, voice’s share of ChatGPT use, and separate Voice and Dictation counts are key metrics to watch.

A forecast compiled for the report projected that monthly active users could exceed 1.3 billion by October 2026, but that was a projection, not a reported result.
