小時候看到"小叮噹"拿出翻譯年糕的時候覺得很神奇
又是拜機器學習的進步之賜，現在手機就可以做出類似的功能了
常用這類 App 和不同語系的人們溝通的人應該會有一種體會：
想要了解一個國家的文化並做有深度的交流，還是要學習它的語言
不過透過機器確實可以讓我們在各方面得到很大的幫助，
我剛上幼兒園的女兒最近要做英文演說比賽，底下是幼兒園給的講稿
=================
Good morning,everyone.
My name is Joan.
My story is Hua Mulan, Hua Mulan.
Long time ago, there was a heroine,
named Hua Mulan.
She lived with her parents and a younger brother.
Recently Huns had begun to invade the border.
Mulan's dad got notices of conscription for the army.
But he is aged, the young brother was only a eight-year-old child. Mulan decided to take her dad's place in the army.
The next day, she went to the market to buy herself a horse and some gear.
Mulan disguised herself into a handsome young man and was heading for army's camp. Mulan contributed a lot to the defeats over the enemy. Finally the Huns were totally defeated and the army returned home in triumph.
The Emperor gave Mulan a rich reward of money and let her return immediately to her hometown.
Back in her own room, Mulan took off her armor and put on a dress. All her fellow soldiers were stunned, "he" would turn out to be a beauty.
People admired Mulan for her self-giving love to her family and her nation.
Thank you for your attention. Bye

在擔心我們自己教她唸會發音不標準的同時，我想到了
文字轉語音TTS 這個技術，
在 python 上導入 gTTS 這套函式就可以輕鬆寫程式把英文稿轉換成標準的英文語音了，在語言學習的道路上學會活用各種工具一定可以事半功倍的，所以別再說唸文組不需要學程式了，程式設計絕對是未來社會最重要的一種能力之一。
前置處理：安裝會用到的函式庫
pip install pyMicVoiceDetection
pip install SpeechRecognition
pip install googletrans==3.1.0a0
pip install gtts pygame
底下讓我們來看看 『翻譯年糕』 的程式如何撰寫吧…
#===========錄音===============
import pyMicVoiceDetection as vd
vd.recordAsyn('test.wav',dur=6,deviceIndex=1,TH=0.1)
#===語音辨識(語音轉文字)======
import speech_recognition as sr
r = sr.Recognizer()
with sr.WavFile('test.wav') as source:
audio = r.record(source)
Text = r.recognize_google(audio,language='zh-tw')
print(Text)
#==========翻譯===============
import googletrans
#print(googletrans.LANGUAGES)
translator = googletrans.Translator()
results = translator.translate(text = Text,src='zh-tw',dest='en')
print(results.text)
#=======文字轉語音============
from gtts import gTTS
tts = gTTS(text=results.text,lang = 'en' )
tts.save('temp.mp3')#,slow=True)
#==========播放mp3============
from pygame import mixer # Load the popular external library
mixer.init()
mixer.music.load('temp.mp3')
mixer.music.play()
