Python中的Python文本到语音

Question

Python中是否有任何库使用Mac Lion的内置文本到语音引擎来实现或允许文本到语音转换？我做谷歌,但大多数是基于Windows的.我试过pyttx.我试着跑

import pyttsx
engine = pyttsx.init()
engine.say('Sally sells seashells by the seashore.')
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

但是我得到了这些错误

File "/Users/manabchetia/Documents/Codes/Speech.py", line 2, in <module>
    engine = pyttsx.init()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyttsx-1.0.egg/pyttsx/__init__.py", line 39, in init
    eng = Engine(driverName, debug)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyttsx-1.0.egg/pyttsx/engine.py", line 45, in __init__
    self.proxy = driver.DriverProxy(weakref.proxy(self), driverName, debug)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyttsx-1.0.egg/pyttsx/driver.py", line 64, in __init__
    self._module = __import__(name, globals(), locals(), [driverName])
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyttsx-1.0.egg/pyttsx/drivers/nsss.py", line 18, in <module>
ImportError: No module named Foundation

我该如何解决这些错误？

Answer 1

这样做不是更简单吗？

from os import system
system('say Hello world!')

您可以输入man say以查看可以使用该say命令执行的其他操作.

但是,如果您想要一些更高级的功能,AppKit也可以进行导入,尽管需要一些Cocoa/Objective C知识.

from AppKit import NSSpeechSynthesizer
speechSynthesizer = NSSpeechSynthesizer.alloc().initWithVoice_("com.apple.speech.synthesis.voice.Bruce")
speechSynthesizer.startSpeakingString_('Hi! Nice to meet you!')

如果你想看到更多的东西,你可以用NSSpeechSynthesizer做看看苹果的文档:https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSSpeechSynthesizer_Class/Reference/Reference html的

Answer 2

如果您将Mac OS X作为您的平台 - PyObjC和NSSpeechSynthesizer是您最好的选择.

这是一个快速的例子

#!/usr/bin/env python

from  AppKit import NSSpeechSynthesizer
import time
import sys


if len(sys.argv) < 2:
   text = raw_input('type text to speak> ')
else:
   text = sys.argv[1]

nssp = NSSpeechSynthesizer

ve = nssp.alloc().init()

for voice in nssp.availableVoices():
   ve.setVoice_(voice)
   print voice
   ve.startSpeakingString_(text)

   while not ve.isSpeaking():
      time.sleep(0.1)

   while ve.isSpeaking():
      time.sleep(0.1)

请注意,AppKit模块是PyObjC桥的一部分,应该已经安装在Mac上.如果您使用的是OS提供的python(/ usr/bin/python),则无需安装它
