Sounds can be played "inline" or by a "helper", depending on the HTML element you use.
声音可以在“线内”播放或作为“提示音”，主要根据你所使用的HTML元素来决定。

Inline Sound
线内声音

When sound is included in a web page, or as part of a web page, it is called inline sound.
当声音嵌套在网页中时，或作为网页的一部分时，我们称之为“线内声音”。

Inline sound can be added to a web page by using the <bgsound> element or the <img> element.
线内声音可以通过<bgsound>元素或<img>元素添加到网页中。

If you plan to use inline sounds in your web applications, be aware that many people find inline sound annoying. Also note that some users might have turned off the inline sound option in their browser.
如果你计划在你的网络应用程序中使用线内声音，请注意，很多人是非常讨厌线内声音的。而且还要注意，有些用户可能会关闭网络浏览器的线内声音选项。

Our best advice is to include inline sound only in web pages where the user expects to hear the sound. An example of this is a page which opens after the user has clicked on a link to hear a recording.
我们的最佳建议是：仅在那些用户希望听到声音的页面中加载声音。其中的一个案例是：在用户点击一个链接之后听到声音时在打开页面。

Using A Helper (Plug-In)
使用在线助手（内置插件）

A helper application is a program that can be launched by the browser to "help" playing sound. Helper applications are also called Plug-Ins.
助手程序使用与激发播放浏览器内声音的应用程序。助手程序也可以叫做插件程序。

Helper applications can be launched using the <embed> element, the <applet> element, or the <object> element.
助手程序可以使用<embed>元素、<applet>元素或<object>元素来激发。

One great advantage of using a helper application is that you can let some (or all) of the player settings be controlled by the user.
使用助手程序的一个最大的好处就是：你可以让用户来控制播放器设置程序。

Most helper applications allows manually (or programmed) control over the volume settings and play functions like rewind, pause, stop and play.
大多数助手程序支持使用手动（或程序）来控制音量属性和播放函数，如：重复、暂停、停止和播放。
