推荐使用带有麦克风的USB耳机进行大多数Avant语言评估。其他选项可能需要IT代表进行更多的准备。like this

耳机准备
在进行测试之前,IT代表应为每台计算机配置耳机,这可能就像插入USB耳机一样简单。
使用Avant Technology Check来验证您的耳机是否正常工作。
测试协调员应确保在测试前插入耳机,并确保考生知道如何使用耳机的线控(如果有的话)。

调整 MacOS 和 Windows 的麦克风音量
如果您在口语部分录音时收到低麦克风或音量低的错误消息,您可能需要在您的首选项中调整声音设置。
在Chrome OS中调整麦克风音量
很遗憾,无法在ChromeOS中调整麦克风的灵敏度。对于在ChromeOS中录音的问题,我们建议尝试使用其他的耳机,让考生增大说话的音量,或者靠近麦克风说话。如果录音问题仍然存在,可能需要将考生移到没有背景噪音的区域。
故障排除
- 确保耳机已插入。
- 检查麦克风是否被静音 - 许多耳机在设备本身或与其连接的线上都有静音按钮。
- 请检查麦克风的音量是否已完全降低。
- 确保考生正在使用支持的浏览器(Microsoft Edge,Chrome,Safari)。
- 尝试刷新页面。
- 停止测试并关闭浏览器窗口,然后重新启动浏览器并重新登录。
- 尝试使用不同的浏览器。
- 尝试在测试期间拔下耳机并重新插入(适用于USB耳机)。
- 确保在浏览器网站设置中选择了“允许”,以便在测试中使用麦克风。
- 检查一下你是否可以在电脑上的其他应用程序中录制声音。
- 如果只有一两个考生受到影响,尝试更换耳机或更换电脑。
- 如果学生在计算机上登录学生账户,请确保用于登录计算机的学生账户没有会影响录制的限制。

If Microphone Isn’t Recording
If you can hear audio but spoken responses are not recording, check that the browser isn’t blocking access to the microphone.
Ensure Browser Isn’t Blocking Microphone
Browsers need to ask permission for a website to use your microphone (as shown in the screenshot below). Users should click “Allow”.

How can I tell if my browser is blocking my microphone?
In Chrome: Click the icon on the left of the address bar. If the mic icon is turned off (as shown below) turn it on.

In Safari (iPad or Mac): Click the icon to the left of the address bar. Click “Website settings“.

Set microphone to “Allow” (as shown below).

If the browser isn’t blocking the microphone, but you still can’t record check to make sure your operating system has the headset setup correctly and check physical connection or mute buttons.
