【语音识别】获得MOOC视频的文本（字幕）
小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
獲得MOOC教學(xué)視頻文本
- 獲得音頻
- 語(yǔ)音識(shí)別
- 小結(jié)
獲得音頻
首先從以下地址下載獲得視頻：http://mooc1vod.stu.126.net/nos/mp4/2016/11/24/1005374032_1241ef3e8a474c9898e1e62f0268ca6c_hd.mp4?ak=7909bff134372bffca53cdc2c17adc27a4c38c6336120510aea1ae1790819de8c3092915cb74e414787263398b5d5a484f5c959cdb6ce7e3c6a3acf758b3c64d3059f726dc7bb86b92adbc3d5b34b132acf7000706a439679744c1c7146151614426afeac364f76a817da3b2623cd41e
這是一個(gè)牛頓運(yùn)動(dòng)定理簡(jiǎn)要回顧的視頻：
利用格式工場(chǎng)提出其中的音軌：

看一下原來(lái)的Demo里面的代碼，我們需要的就是這個(gè)函數(shù)返回的字典形式的result：
