    DLL helps us save time in teaching. In addition, teaching will become smoother if we can broadcast pre-recorded voice and video in the lessons.

    Language Teacher | Saudi Arabia

    My school emphasizes Mandarin learning and we know the importance of “Practice Makes Perfect”. However, we find that most of the students are shy in speaking Mandarin. With DLL, my students can speak Mandarin in front of the computers.

    Language Teacher | United Kingdom

    Even if students can practice English by themselves in class, they don’t know whether their pronunciation is correct while they practice language. Now, my students can compare their pronunciation with the correct one by listening and recording in DLL.

    Language Teacher | Korea

    It is difficult to assess each student’s language pronunciation in a class. DLL can let me collect all students’ recording for assessment after class.

    Language Teacher | Malaysia

    We appreciate the save function of student recordings. Students can compare their own pronunciation with the correct one when they listen again to their own recordings. So, they can recognize their own mistakes in pronunciation.

    Language Teacher | Hungary

    Now I don’t need to worry about preparing teaching materials. It is convenient for me to record my voice and video before lessons.

    Language Teacher | Hong Kong

    In the past, we cannot listen and correct all students’ pronunciation in real-time. Nowadays, we can assign any students to pronounce the words and give them personal advice through DLL.

    Language Teacher | China

    Students have different levels of proficiency in foreign language. DLL allows them to repeatedly listen to the voice and video according to their own learning pace.

    Language Teacher | Philippines

    Sometimes, we want to prepare own teaching materials instead of using outside sources. We can choose between broadcasting our pre-recorded materials and outside sources in DLL.
