• 項(xiàng)目構(gòu)想

錄制一段音頻并識(shí)別成字符，將字符傳入圖靈機(jī)器人并獲得回復(fù)，將回復(fù)合成音頻文件并播放。

• 項(xiàng)目感想

訊飛語音識(shí)別率還行，但是項(xiàng)目容錯(cuò)率低，并且項(xiàng)目基本調(diào)用API，沒進(jìn)一步研究語音識(shí)別技術(shù)的過程與實(shí)現(xiàn)，不過還是頗有收獲，學(xué)習(xí)到了完成項(xiàng)目期間出現(xiàn)各種各樣的問題的解決辦法，所以只要你敢想，敢動(dòng)手去做就一定會(huì)有收獲。

• 項(xiàng)目API調(diào)用

訊飛語音識(shí)別，百度語音合成，圖靈機(jī)器人。

• 項(xiàng)目語言以及庫

Python+playsound+pyaudio+wave+os+百度API+訊飛API+圖靈機(jī)器人API。
