Enjoy free Internet calls

Currently, one of the essential software for online communication is instant messaging software such as MSN Messenger and QQ. In addition to text chat, these software can also directly perform online voice conversations, that is to say, you don't have to spend a penny to enjoy the Internet call for free.

1. Network conversation in MSN Messenger

While some functions of MSN Messenger are slightly inferior to those of QQ, MSN Messenger is the first software to introduce language dialogs into instant messaging, and supports both PC-PC and PC-phone dialogs.

For a PC-PC conversation, first ask your computer to have a sound card and a microphone installed, and then double-click the avatar that needs voice chat friends, after entering the text dialog window, click "Start conversation" in the upper right corner to send a chat request to the other party. Next, you need to set the speaker and microphone volume settings with the help of the setup wizard. After the settings are complete, you will see the interface shown in the figure. Once the recipient accepts the settings, you will be able to chat online through the microphone.

 

 

At this time, you should keep your mouth and fingers idle and use them together. It feels like the two of you are in a chat room. In addition, if you have a digital camera on your computer, you may wish to activate the video conversation function so that messenger can draw you closer. At this time, as long as the network conditions are ideal, you can directly face-to-face communication, even if a friend is far away, you can see his appearance and listen to his voice.

In addition, the PC-phone function of messenger can call a phone to a common phone over the Internet, in this case, you only need to click the "call" button on the right of the Main Window and type the other party's phone number in the displayed dial-up window.

 

 

However, the current version of messenger only supports free calls to Canada and the United States, so if you have friends in these two countries, congratulations!
　　
2. online conversation in QQ

Qq also integrates the network conversation function, so that you can chat with friends by using a sound card on your computer. The voice conversations attached to QQ can be divided into three types: one is the voice file mode, the other is the conversation in the two-person world, and the other is the dialogue that contains the video image.

1. voice file mode Dialog

Set the volume of the microphone and speaker in windows, click the target user in the QQ friends list, and select the "send voice" command in the pop-up menu. In the window, you can click the red "Recording" button, record the words you want to say through the microphone, and then click "stop.

 

 

After recording, you can also click the "play" button to check whether there are any mistakes or missing content. After confirmation, click the "send" button to send the content directly to online friends, so that others can hear your words.

However, this chat method is half-duplex, that is, only one person can speak, and the other person can only listen to it after a while. Although this method can completely retain all the chat content in the form of files, it is obviously not suitable for our online conversation and chat. Therefore, we recommend that you use the other two types of online conversations.

2. Dialog in the second World

In the two-person world, dialogs not only allow both parties to communicate with each other directly through a microphone, but also provide text input boxes. In this way, speech dialogs can also be supplemented through text.

Click the target user to chat in QQ and select the "two-person world" command from the pop-up window. In this window, you can use a microphone to chat with your friends, the other party will hear your voice in the first place. To achieve better speech performance, we can adjust the quality of Speech data transmission by using two slide Bars: "sensitivity" and "allowable delay time". The default value is generally used.

 

 

3. Video conversation

In QQ 0630, the support for cameras has been added, so that those who have cameras can directly communicate with friends in the distance through the camera.

Before video conversation, we recommend that you adjust the settings of related devices. Click a friend who needs to chat and select "video phone number-> video adjustment" from the pop-up menu, then, follow the pop-up setting Wizard to set the voice, screen, and other related aspects ., You can set whether voice chat focuses on the quality of voice or the pursuit of greater compression ratio. At this time, you can decide based on the individual's Internet access conditions, for those broadband users, You can naturally choose "better quality "; if you still use a kitten to access the Internet, it is recommended to select "Greater compression rate.

 

 

After the preceding settings are complete, click a friend who needs to chat again and select "Video Phone-> Video Phone" from the pop-up menu, if everything goes well, you can see the picture. In the left-side window, the camera screen of both sides of the chat is displayed. Both sides of the conversation can directly use the microphone for voice chat or input text to supplement the conversation.

 

 

Because MSN Messenger and QQ both adopt special speech compression transmission technology, the chat voice quality is still very good. I have used a cat with 56 K. I can hear the voice of the other cat clearly during the peak hours at around 8 o'clock in the evening, but there is a slight delay. When I try it at around 2 o'clock in the morning, not only is the voice clear, but there is no delay. It seems that they are not very harsh on the network. However, if you want to perform a video chat, this puts a high requirement on the network. We recommend that you do not try the 56k dialing method. Otherwise, the intermittent screen will not only affect your chat mood, more importantly, video data transmission also occupies a large amount of bandwidth, which can cause obvious voice latency.
