Why Does Cafetalk Use Skype?
Wide Audible Range of Tone
For online language lessons, sound quality is essential. Skype is popular, free and has higher sound quality compared to other chat messengers such as Yahoo and MSN. Skype has many users all over the world, so we have selected Skype as the most appropriate software for Cafetalk.
To explain this more technically, you can hear only sounds in the range of 300Hz～3KHz on the phone. Skype covers everything from low key humming sounds up to screaming voices. For instance, similar sounds like F and S can be easily discerned on Skype, allowing you to have a more pleasant and valuable lesson.
