Zhizi, a female employee of Japan life insurance company in Tokyo, Japan, is one of the earliest users of wechat. So far, she and her boyfriend have used wechat for more than half a year. They love the simple use of this software and rich chat expressions.


    However, many times, no matter words or expressions, can not replace voice calls. Even if the telephone fee is very expensive, Zhizi and her boyfriend still often call. After all, they can hear each other''s voice with their own ears. That feeling is completely different from the cold text chat.


    That day, when Zhizi opened her wechat again to send a message to her boyfriend, she suddenly found that the update introduction popped up after the wechat startup page. Most applications of today''s smart phones are automatically updated under WiFi. It is obvious that wechat has been updated now, and the pop-up prompt is nothing more than to inform users of what content has been updated.


    Zhizi, who wanted to turn it off directly, inadvertently saw the update listed in the first item:


    1. Add voice chat function. Users can long press the voice key to record their own speech content, and send their recorded voice to the other party after stopping the key;


    Single recording voice is limited to 60 seconds;


    You can use voice call in more input options to make continuous voice call with the other party;


    All voice services consume the corresponding traffic fee according to the call duration.


    Next, there is a detailed graphic introduction to the voice chat function. After reading the graphic introduction, Zhizi didn''t care about other updates, but directly couldn''t wait to open her boyfriend''s chat interface.


    Sure enough, in front of the text input box at the bottom of the chat interface, there is a common microphone voice icon button. Zhizi clicked the voice icon. The original input box has directly changed into a button with a microphone icon and holding down a few words to speak. In front of the button, it has become a keypad representing text input.


    Zhizi pressed and held the "press and hold to speak" button, and a translucent pop-up mask popped up in the center of the chat interface. On the top of the mask, in addition to a larger microphone icon, there was a line of words "slide your finger up, cancel sending". Zhizi strangely shouted her boyfriend''s name to the mobile phone, next to the microphone, There is also a fluctuating sound input diagram according to her sound size.


    After Zhizi releases the thumb holding the "press and hold" button, the voice message is sent out. A new message appears on the right side of the chat bar. In addition to the avatar representing her personal identity, the message on the left side of the avatar is a message marked with voice icon and voice duration.


    In addition, Zhizi also found that the length of the words she said before and after was different, and the length of the message information was also different. The longer the voice time, the longer the length of the message information, which was very intuitive.


    This is Zhizi''s first time to see the voice chat function on the mobile phone, not to mention on the mobile phone, but on the computer. She has never seen the voice chat software. In her past thinking, there is only one way for two people to chat and want to talk, that is, calling. This update of wechat has completely subverted her cognition.


    The curious Zhizi was like meeting a novel toy. She kept trying to send voice messages one by one, and even hummed two songs. Zhizi sent more than a dozen voice messages to her boyfriend. After a moment, she received a message from her boyfriend. He sent the same voice messages, but different from the messages she sent, In addition to his message on the left, the color of the voice message he sent is deeper, and there is a small red dot in the upper right corner of the message. Zhizi, who has read the updated instructions, knows that this indicates that the voice message has not been read.


    Zhizi clicks on voice and her boyfriend''s voice comes from her mobile phone. Like her, her boyfriend is very novel and likes the voice function newly launched by wechat. However, he does it after all. He knows that voice input is also available in some computer chat software, but it is not popular in Japan. Therefore, his girlfriend Zhizi doesn''t know, but the mobile chat software with voice function, Not to mention Zhizi, he used it for the first time.


    Zhizi and her boyfriend constantly use voice chat to send messages. This novel way of chat makes them completely give up words and expressions at this time.


    More than ten minutes later, the two people who were still not satisfied chose voice call from more input, because according to the science and engineering calculation just made by Zhizi''s it boyfriend, he found that the wechat setting included the traffic usage statistics function. Just now, they talked for a long time and consumed less than 5m traffic in total, which is better than directly using the phone without free call minutes, It''s much cheaper!


    The update of wechat version 2.0 has set off an upsurge of using voice chat among old wechat users all over the world. Now it is the beginning of 2010. There is no voice chat function in any mobile chat software in the world, because everyone thinks that since the mobile phone can make calls, why does the chat software add voice chat function? Isn''t that unnecessary?


    Is it really unnecessary? At this time, only Fang Zhe, who was reborn from the heyday of mobile Internet in his previous life, has a deep enough understanding of the function of adding voice chat to mobile chat software.


    Voice chat is a novel function for most mobile Internet users today. At present, there is no voice chat function on mobile QQ or other mobile social software abroad. Users want to send messages to their friends. In addition to words and expression pictures, voice can only be realized by calling.


    But in fact, many people have trouble making calls or expensive free calls, which potentially curbs this chat demand, not that users do not have this demand.


    In previous generations, foreign kakaotalk and line, domestic meter chat and Tencent wechat have developed rapidly, and the voice chat function is indispensable. If wechat, which added the address book function before, is a potential king tiger in the mobile chat software industry in the future, the voice function is the tiger''s wing, which will help wechat, From the previous dormant period to the rapid development period!


    Two days later, only two days after the wechat version 2.0 was updated, wechat spent more than half a year to increase the number of daily active users from more than 3 million to more than 4 million, and the number of new registered users per day directly doubled from more than 20000 to more than 40000!
