Doubao LLM is the most popular AI chatbot in China. Deployed on the phone, it works at the operating system levelallowing AI to see what's happening on the screen and use apps, performing tasks such as retrieving and organizing files, filling out forms, and even suggesting restaurants that match budgets and preferences.

The assistant also has memory, allowing it to store information on the device – appointment notes, addresses, the child's age and preferences – and turn them into reminders or tasks. Users can ask questions such as “Where was I on the train last week?” or “Where was the cafe that I liked near the office?”

It's a step up from older voice assistants like Apple's Siri, which work in a way where responses can suffer from latency and a lack of emotional nuance. In these systems, speech is recorded, converted to text and sent to a server for analysis, and then the response is read aloud using a separate text-to-speech tool. ByteDance's AI, on the other hand, uses a speech-to-speech system that allows for faster responses and even allows the user to interrupt the assistant mid-sentence – much the same way you can interrupt a friend or colleague.

According to Guangdong Yangcheng Evening NewsDubao's updated voice calls are almost “indistinguishable from human ones” when it comes to realism and emotions such as joy and sadness. However, ByteDance cautioned that the technology is still in beta and requires further testing before it is rolled out more widely.

This Her moment of technology and Science fiction enthusiasts have been waiting? IN San FranciscoBeijing, Seoul and Cupertino engineers have the same goal: An AI assistant that listensunderstands and acts without forcing you to think about middleware. ByteDance Doubao phone assistant suggests how fast it is the future is coming.

A similar technology exists in the USA. OpenAI's GPT‑4o, introduced in 2024, also supports real-time conversations, and Google's Gemini Live mode can also offer real-time interruptible voice chats on phones. And AI-powered assistant apps are becoming increasingly effective at tasks such as summarizing calls and emails, translating, booking appointments and composing responses. But the main difference between these features and Doubao is that it is a Chinese-made artificial intelligence, completely built into a Chinese-made smartphone, specifically for the Chinese market.
