Digital Transcription of Chinese youtube videos

Digital transcription for a research project I need about 20 hours worth of chinese(mandarin) youtube videos to be transcribed by speech recognition software it does not have to be accurate, nobody will read it, it will be analyzed by a computer. The videos should be inteviews or other natural conversations. Movies also work. they should be about different topics. i need it in pinyin. Heres how i did it: [login to view URL] the automatic youtube transcription [login to view URL] it into a chinese-to-pinyin converter the problem is that most videos don't have the transcription enabled, so you would have to download the sound, upload it again(with transcription enabled) and then copy it you could also use other speech recognition software it's up to you (siri, google now or something)
