Over 150 million people use ChatGPT’s voice and dictation features weekly

OpenAI announced on July 8 that more than 150 million people use ChatGPT's voice and dictation features weekly, a combined figure disclosed in its GPT-Live announcement. The company simultaneously unveiled GPT-Live as a new voice model, highlighting "full-duplex" capability—generating responses while the user is still speaking—as the core change to voice conversations. OpenAI cited use cases including hands-free assistance, language practice, commuting conversations, and bedtime stories, but did not break out separate user counts or methodology for voice versus dictation, so the 150 million figure cannot be read as voice-only usage. The announcement underscores OpenAI's push to deepen engagement in voice AI, a market contested by rivals including Google and ElevenLabs. Watch for adoption metrics on the new full-duplex model, monetization details for voice features, and competitive responses from other AI providers.
