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)。

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。
