EnglishCentral's Intellispeech system evaluates your accent. The grade you receive when speaking the videos is a combination of three elements:
While in speech mode, you will see:
While going (in speak mode), the score you get per line is a so-called percentile. The percentile is about how well your spoken line matched the spoken range of native English speakers. Below you see how they are shown.

After speaking all the lines in the video, you'll see a video grade. This grade is a cumulative measure of the Intellispeech engine across all lines you have spoken in the video. In the following table you can see which grade you should get per required CEFR Level:
Required CEFR Level
|A||93 - 99%||C1|
|B+||73 - 93%||B2|
|B||48 - 73%||B1|
|C+||23 - 48%||A2|
|C||3 - 23%||A1|
|D||1 - 3%||-|
