The initiative builds on OpenAI’s ongoing goal to broaden access to its AI assistant, ensuring that people who do not own a smartphone or do not have ready access to a computer can still interact with ChatGPT in a meaningful way. In addition to the voice line for users in the United States, OpenAI has enabled a parallel text channel via WhatsApp for international users, presenting a versatile set of entry points for diverse audiences.
The toll-free voice line: availability, duration, and user experience
OpenAI announced the introduction of a toll-free voice line designed to connect US callers with ChatGPT through an interactive, spoken dialogue. The service is free for up to 15 minutes per session, offering a substantial window for users to ask questions, seek explanations, ask for tasks, and engage in a natural back-and-forth with the AI. The core idea behind this feature is to provide a voice-enabled interface that does not require users to own or operate a smartphone or to have a persistent internet connection through a dedicated app. By removing the necessity of a mobile device, the voice line broadens the potential user base to include individuals who may rely on landlines, basic mobile devices, or other scenarios where a traditional app-based interaction would be impractical.
Upon dialing the toll-free number, callers are greeted by a voice that identifies ChatGPT and clarifies that the conversation may be reviewed for safety purposes. This upfront notice reflects a standard safety and quality-control measure that OpenAI employs across various modalities, ensuring that content is monitored to protect users. The greeting sets the tone for a conversational experience in which the AI is positioned as an assistant capable of handling a wide array of requests. In practice, users are invited to pose any question or task they would typically direct to an AI assistant, and the system responds in real time, enabling a genuine, interactive dialogue.
During demonstrations, the voice interface has been shown performing a range of tasks that highlight its versatility. Examples include identifying a distinctive house in California—a task that relies on observation prompts and descriptive reasoning—and translating a message into Spanish for a friend, which showcases bilingual capabilities and the flexibility to switch languages mid-conversation. The demonstrations also illustrated the accessibility of the service across different device types. OpenAI staged calls from diverse hardware, including an iPhone, a traditional flip phone, and a vintage rotary phone, underscoring the platform’s adaptability and its emphasis on accessibility for users with varying levels of technology access.
