1. Text to Audio.
#Text to Audio # Import the required module for text to speech conversion from gtts import gTTS # This module is imported so that we can play the converted audio import os # String text from file that you want to convert to audio f = open("sentence.txt") mytext = f.read().replace("\n"," ") f.close() # print(text) # mytext = 'Dreamtime Story - Barramundi. A long time ago in the Dreamtime, there were no fish, so the people lived on animals, roots and berries. The Aboriginal people were very happy. That is except Boodi and Yalima; for they wanted to marry. But the tribe insisted that Yalima marry one of the old men, to look after him. Boodi and Yalima decided to run away, and so they ran as fast as they could. Now, to go against the Elders of the tribe is breaking the law, and they probably would be punished. Soon the men of the tribe began running after them. Boodi and Yalima ran on and on, and soon they became very tired. They came to the edge of the land, where the water began. They knew that to survive, they would have to fight. With the angry tribe descending on them, they quickly gathered wood, and made as many spears as they could. But the tribesman were too many, and soon the spears were all gone. Boodi turned to his beloved Yalima and said, For us to be together forever, we must go into the water to live. And so they did. They are still there in the shape of the Barramundi hiding amongst the logs and reeds.' # Language in which you want to convert language = 'en' # Passing the text and language to the engine, here we have marked slow=False, # which tells the module that the converted audio should have a high speed myobj = gTTS(text=mytext, lang=language, slow=False) # Saving the converted audio in an mp3 file named barramundi myobj.save("barramundi.mp3") # Playing the converted file os.system("mpg321 barramundi.mp3")
2. Audio to Text
#Audio to Speech #!/usr/bin/env python3 import speech_recognition as sr # load audio file from same directory from os import path AUDIO_FILE = path.join(path.dirname(path.realpath(__file__)), "tiddalick.wav") # use audio file as input r = sr.Recognizer() with sr.AudioFile(AUDIO_FILE) as source: audio = r.record(source) # read the entire audio file # recognize speech using Google Speech Recognition try: print("Google Speech Recognition thinks you said " + r.recognize_google(audio)) except sr.UnknownValueError: print("Google Speech Recognition could not understand audio") except sr.RequestError as e: print("Could not request results from Google Speech Recognition service; {0}".format(e))
