佩戴耳机:麦克风平行嘴巴 2CM
调节音量:音量不宜过低或过高,调好不再碰麦,防噪音干扰
若调音环节出现问题,应及时跟考官提出更换电脑的要求
一旦试音结束,不再有多余动作
考试注意事项:试音环节

影响评分的特征主要可分为三类:语音的完整性;语音的音段质量;语法和语义。
机评原理 - 提取采分特征
通过语音转文字技术,实现语音完整性评测。
通过语音模型分析技术,实现对音段质量及韵律节奏的评测。
通过深度神经网络技术,实现对语法及语义的评测。

完整性特征
音段质量特征
语法、语义特征
通过人工智能技术对专家打分数据进行分析,算出每个特征权重:
举例:原文:I like dogs. (总分4分)
得分=满分 *(单词*0.75+语调*0.25)

His father(s) is a worker(s).
I have no interest(ing).
----加音导致准确度扣分
I don’t thin(k) I can do i(t) at the momen(t).
I am not clever(er) than you.
----吞音导致准确度扣分严重,完整度也会失分

A whale would be a huge prize for any meat-eating hunter, and these whales, trapped by the ice, are within reach of polar bears. Well aware of the danger, they stay in the deep water as long as they can, but they can only hold their breath for about 20 minutes. Catching a four-metre-long whale that weighs one tonne is no easy task, even if that whale is weakened by starvation. Day by day, as the hole gets bigger, it becomes increasingly difficult for the bear to land a whale. It may have taken a long time and a lot of patience, but a catch when it’s made brings abundant rewards.
模仿朗读 – 高分学生常见问题
失分点 例句
1. 连读 Well ︵ aware of the danger, they stay in the deep water as long as they can.
It may have taken︵a long time and a lot ︵ of patience, …
2. 停顿 but a catch when it’s made / brings abundant rewards.
3. 吞音 they stay in the deep water as long as they can, but they can only hold their
breath for about 20 minutes.
4. 发音不饱和 … and these whales, trapped by the ice, are within reach of polar bears.

中分段学生画像:熟悉大部分基础词汇,但对部分核心词汇的发音仍不准确,且模仿性较差,导致准确性失分较大。此外,缺乏连读、停顿、节奏等语篇发音技巧。
提分方向:熟练掌握考纲词汇发音,侧重培养跟读模仿能力,尤其是对生词的短时记忆和模仿;加强语篇朗读技能。

低分段学生画像:绝大部分词汇不认识,只能凭借字面猜测发音,勉强读完或胡乱读完。但准确性方面,几乎没有发音准确的地方或完整的句子。准确度和流畅度失分。
提分方向:练习基础单词的发音,模仿跟读,先确保能够按照文本读完文章;锻炼自然拼读能力。
