Chinese tech company ByteDance recently launched an AI voice assistant for smartphones, which can work independently to help with daily tasks — reminding many of the AI in the movie “Her”, where the main character builds a close bond with his phone’s voice.

Powered by ByteDance’s popular Doubao large language model (LLM), this capable assistant can open browser tabs, book tickets, and search for phone data easily. For now, it’s only available on the Nubia M153 phone in limited quantities, but ByteDance plans to offer the tool to other Chinese phone makers.

Additionally, operating at the phone’s system level, the AI can “see” the screen and use apps freely. It can organize files, fill out forms, or even recommend restaurants based on a user’s budget and taste. The assistant also has a memory function, storing details such as meeting notes, addresses, or a child’s preferences, and setting them as reminders. 

This represents a big step forward from older voice assistants. Those systems often respond slowly and sound less natural. Usually, they convert speech to text, send it to a server to process, and then read the answer aloud. Doubao, however, uses a speech-to-speech method that makes replies faster and more natural. Users can even interrupt it while it is speaking, just like in a real conversation. Some Chinese media say Doubao’s updated voice sounds almost human, expressing emotions like joy or sadness naturally. Still, ByteDance notes the technology is still in testing and needs more improvement before wider release.

For tech and science-fiction enthusiasts, ByteDance’s new AI assistant is an exciting development. It suggests that the “Her” moment — when AI assistants can listen, understand, and act seamlessly (无缝地) — is no longer just a plot in movies, but a future that’s quickly approaching. As AI technology continues to advance, such intelligent tools are likely to become more common in people’s daily lives, bringing greater convenience and a more human-like experience.

1.1. Why is the movie “Her” mentioned in Paragraph 1?

A To introduce a famous AI movie.

B To explain the AI’s name origin.

C To highlight AI’s emotional bond.

D To compare it with traditional assistants.

解析：选C。C 推理判断题。文章第一段提到电影《Her》是为了说明字节跳动新推出的AI语音助手能够像电影中一样，与用户建立亲密的情感纽带（“the main character builds a close bond with his phone’s voice”）。其目的并非单纯介绍电影（A错），也未解释AI的名称来源（B错），更不是与传统助手比较（D选项的“与传统助手比较”确实是后文<第四段>的主要内容，而非第一段提到《Her》的目的）。因此，提到电影主要是为了强调AI可能与人建立情感联系的特点，故C正确。

2.2. What can be inferred about the AI’s current availability?

A It is widely used in many phones.

B It has limited access now.

C It’s for foreign phone models.

D It lacks practical functions now.

解析：选B。B细节理解题第二段明确提到“For now, it’s only available on the Nubia M153 phone in limited quantities”，说明目前该AI助手仅在特定手机型号上限量提供，访问权限有限。A项“广泛用于多款手机”与原文矛盾；C项“用于国外手机型号”未提及；D项“目前缺乏实用功能”错误，因第三段列举了多项实际功能。故B正确。

3.3. What makes Doubao different from older voice assistants?

A It responds more slowly.

B It needs text conversion steps.

C It allows more natural human interaction.

D It depends on external servers greatly.

解析：选C。C推理判断题。第四段对比了豆包AI助手与旧版语音助手的区别：旧版响应慢、不自然，需经过“语音转文本→服务器处理→朗读答案”的流程；而豆包AI助手采用“语音直接转语音”技术，响应更快、更自然，且支持用户随时打断对话，实现了更接近真人交互的体验。A项“响应更慢”与原文相反；B项“需要文本转换步骤”是旧版的特点；D项“严重依赖外部服务器”并非豆包AI助手的主要优势。故C正确。

4.4. What is the author’s attitude toward the new AI assistant?

A Clearly supportive and optimistic.

B Doubtful about its real value.

C Strongly critical of its risks.

D Completely unconcerned.

解析：选A。A观点态度题。作者在末段用“exciting development”“future that’s quickly approaching”“greater convenience and a more human-like experience”等积极词汇描述该AI助手，体现出明确的支持与乐观态度。B项“怀疑其实用价值”、C项“强烈批评其风险”在文中均未体现；D项“完全不在意”与作者详细评述的态度不符。故A正确。
