Whether the use of dialects in meetings will affect a person's level of attention actually depends on a variety of factors, including the nature of the meeting, the background of the participants, and the cultural environment of the region. Here are some factors that may affect this situation： 1. **Conference formality and cultural background** -In formal, international meetings, the use of Mandarin or a common language (such as English) is usually considered more professional and helps to ensure that everyone can understand and participate in the discussion. If someone uses a dialect on this occasion, it may make people feel that they are not formal or professional enough, thus affecting their degree of attention. -However, in some local meetings or informal occasions, the use of dialects may instead be regarded as grounded, cordial, and even help to narrow the distance with the audience. 2. **Language habits of participants** -If most of the conference participants come from the same dialect area, using dialects may make people feel more cordial and even help to better express certain localized views. -But if the participants are from different regions, using dialects may confuse or exclude others, thus affecting the communication effect. 3. **Personal expression and professionalism** -No matter what language is used, the most important thing is whether the content expressed is clear, professional, and logical. If a person uses a dialect but expresses very valuable content, he will still be valued. -On the contrary, if you use Mandarin but your expression is vague or lacks depth, it may also be considered unprofessional. 4. **Social prejudices and cultural concepts** -In some regions or cultures, dialects may be considered not “high-end” or “formal" enough. This prejudice may affect people's perceptions of dialect speakers. However, this concept is gradually changing, and more and more people are beginning to pay attention to the cultural value of dialects. **Summary** The use of dialects does not directly determine whether a person is valued by itself. The key lies in the effectiveness of communication, the quality of content, and the environment of the meeting. If you are worried that using dialects will affect others' perceptions of you, you can try to adjust the language use according to the occasion, while ensuring that the content of the expression is clear and powerful. In any case, maintaining self-confidence and a professional attitude is the most important thing.
