In this report, we will evaluate the performance of the 6 most representative PA engines, focusing on the result of accuracy, fluency, and prosody in utterance level, accuracy in word level, and accuracy in phoneme level, which are critical and commonly recognized parameters for measuring. For the following content of this report, we will first introduce the 6 engines evaluated and the features we use. Later, we will describe the data we prepared for this experiment. Next, we will illustrate the methodology and evaluation metrics used for the pronunciation assessment. Moreover, we will present the evaluation results and the analysis based on each aspect. Last but not least, this report ends with a conclusion and further discussion.
