The ClearTalk testing service scores both the content and the manner of speech of the test taker. It uses advanced speech processing and machine learning technology to grade the test taker based on the content, pace, fluency, pronunciation and grammar in the responses.

The service provides reports of each individual skill area and the overall score. The test taker will get the test report instantly on the phone after he/she finishes taking the test. The overall score of the test represents the test taker's ability to understand spoken English and speak it intelligibly in a neutral accent at a normal conversational pace on everyday and workplace topics.

The overall score is a weighted combination of the five sub-scores in Pronunciation, Fluency, Sentence Mastery, Vocabulary and Listening Comprehension. Scores are reported in the range from 0 to 100.
