I am a professor who teach chinese at university. I majored in phonetic to know how Chinese sounds are like. In Chinese, pitch of the each syllable and intonation curve(pitch countour) are very important. We researchers use PRAAT to measure the students pronunciation. However, it is not is to let all the chinese learners use praat to compare their intonation curve with the Chinese native speakers. In Japan, NHK provide that kind of service through their web. ([login to view URL]) Which is not free. I want to develop app and provide it freely to anyone, it can be my students or any people who learn chinese. 1. user need to up load mp3 file which they need to practice ( Chinese native speaker's voice) 2. If user play that mp3 file, the pitch contour show up. 3. If user record his/her own pronunciation, his/her pitch contour show up, so the user can compare his/her pitch are correct or not. ---------------------- 4. If it's possible to produce them text of that mp3 file (if the user upload text file..), that would be perfect.
