python实现将文本转换成语音的方法

本文实例讲述了python将文本转换成语音的方法。分享给大家供大家参考。具体实现方法如下：

    # Text To Speech using SAPI (Windows) and Python module pyTTS by Peter Parente
    # download installer file pyTTS-3.0.win32-py2.4.exe 
    # from: http://sourceforge.net/projects/uncassist
    # also needs: http://www.cs.unc.edu/Research/assist/packages/SAPI5SpeechInstaller.msi
    # and pywin32-204.win32-py2.4.exe at this date the latest version of win32com
    # from: http://sourceforge.net/projects/pywin32/
    # tested with Python24 on a Windows XP computer  vagaseat  15jun2005
    import pyTTS
    import time
    tts = pyTTS.Create()
    # set the speech rate, higher value = faster
    # just for fun try values of -10 to 10
    tts.Rate = 1
    print "Speech rate =", tts.Rate
    # set the speech volume percentage (0-100%)
    tts.Volume = 90
    print "Speech volume =", tts.Volume
    # get a list of all the available voices
    print "List of voices =", tts.GetVoiceNames()
    # explicitly set a voice
    tts.SetVoiceByName('MSMary')
    print "Voice is set ot MSMary"
    print
    # announce the date and time, does a good job
    timeStr = "The date and time is " + time.asctime()
    print timeStr
    tts.Speak(timeStr)
    print
    str1 = """
    A young executive was leaving the office at 6 pm when he found 
    the CEO standing in front of a shredder with a piece of paper in hand. 
    "Listen," said the CEO, "this is important, and my secretary has left. 
    Can you make this thing work?"
    "Certainly," said the young executive. He turned the machine on, 
    inserted the paper, and pressed the start button.
    "Excellent, excellent!" said the CEO as his paper disappeared inside 
    the machine. "I just need one copy."

    print str1
    tts.Speak(str1)
    tts.Speak('Haah haa haah haa')

    # replace words that are hard to pronounce with something that 
    # is spelled out or misspelled, but at least sounds like it
    p.AddMisspelled('Ctrl', 'Control')
    str3 = p.Correct('Please press the Ctrl key!')
    tts.Speak(str3)
    print
    print "2 * 3 = 6"
    tts.Speak('2 * 3 = 6')
    print
    tts.Speak("sounds goofy, let's replace * with times")
    print "Substitute * with times"

    for k in range(7):
      print str5
      tts.Speak(str5)
      time.sleep(0.3)
    tts.Rate = 0
    tts.Speak("Wow, not one mispronounced word!")
