Keeping track of excecises and evaluating pronunciation.
SpeakGoodChinese keeps a table with practice statistics for each session. It tabulates which words and phrases have been practiced, how often they have been practiced and what the results were. This table can be inspected on the Settings page under Overview with the Performance button. These data are lost between sessions.
The tabulated practice statistics can be stored with the Save button and loaded again with the Read button. The extension of this file must be .tsv. This file can be used to keep track of the words and phrases that have been practiced and how often they have been practiced between sessions.
SpeakGoodChinese can store recorded exercises for pronunciation evaluation. On the Settings page, press the Save Audio button and select a folder to store the recordings. A blue dot will be displayed in the lower right corner of the Main page as long as recordings are stored. While the blue dot is visible on the Main page, all audio will be stored. Only the last version of each pinyin word will be kept. The recorded files have file-names constructed of the pinyin spelling of the word and the extension .wav. Every recording will overwrite existing recordings of the same pinyin word. The storing of new recordings can be terminated by pressing the Save Audio button again. When available, SpeakGoodChinese will display and play the stored recordings for evaluation until a new one is recorded. The recordings are available even when the Save Audio button has been deactivated.
Practice statistics are automatically stored together with the speech recordings. During the time the Save Audio button is active, practice tables cannot be manipulated (i.e., saved, read, or cleared) and the relevant buttons will be greyed out.
For evaluation and grading purposes, a student can upload a folder with stored practice recordings and a corresponding practice summary. When the teacher opens the student's practice summary in SpeakGoodChinese using the Read button, she can listen to the audio recordings using the Play button while she steps through the list. A grading can be entered by pressing one of the number keys 1-0 (0 translates to 10). This grading will be stored in the practice summary. Gradings will be displayed in the comment area below the Pinyin. The average grading is visible as a small, blue numeral in the bottom right corner of the Main page.
The file with the practice summary can be send to the student (e.g., Save to a suitable folder). When the student opens this practice file, and the file is not stored in its original folder, a window will open to ask for the associated directory with the recordings. The student can then evaluate her performance grading.
Note: Do not change the name of the file! SpeakGoodChinese expects the practice summary to have the same name as the folder.
For testing SpeakGoodChinese there is a special mode where the recognition results of stored practice recordings can be displayed in the grading mode. To achieve this, add a file called TestSpeakGoodChinese2.txt to the directory which contains the practice recordings.
