pyttsx and gTTS module errors

问题:

windows 10-64bit

I'm trying to use some text-to-speech tool to read text from lines of .txt document, something like this:

so with pyttsx:

import pyttsx
engine = pyttsx.init()
engine.say('my voice')
engine.runAndWait() 

I got this error:

Traceback (most recent call last):
  File "...", line 1, in <module>
    import pyttsx
  File "/.../pyttsx/__init__.py", line 18, in <module>
    from engine import Engine
ImportError: No module named 'engine'

now gTTS, available as gtts_token, so how to use it? because this way module is unrecognizable:

import gtts
blabla = ("my voice")
tts = gtts.gTTS(text=blabla, lang='en')
tts.save("C:/rec.mp3")

or:

from gtts import gTTS
blabla = ("my voice")
tts = gTTS(text=blabla, lang='en')
tts.save("C:/rec.mp3")

error:

 import gtts
ImportError: No module named 'gtts'

also I'm want try to use espeak but not sure how to install it, is it available with pip install or I have to install it some other way to try it:

import subprocess
text = '"my voice"'
subprocess.call('espeak '+text, shell=True)

or:

import os
os.system("espeak 'my voice'")

so I'm trying to find some solution, but everything I tried is not working here...

回答1:

for python3 use

pyttsx3

Its a new library compatible with both python3 and python2. Unlike gTTS it doesn't need internet connection and there is no delay in the sound produced.

Install:

pip install pyttsx3

Usage :

import pyttsx3
engine = pyttsx3.init()
engine.say("Hi this is working ");
engine.setProperty('volume',0.9)
engine.runAndWait()

I am using windows 10 and Python 2.7.

For pyttsx:

Below code is working fine for me. I did get ImportError: No module named win32api error for which I had to install win32api from here

After that I could play "my voice". Although the quality and fidelity of spoken sound was very low. gtts is much better in that regards.

import pyttsx
engine = pyttsx.init()
engine.say('my voice')
engine.runAndWait() 

For the error you are getting, Can you look into your python folder and see if engine.py file is present?

For e.g. in my case, I've pyttsx modules installed at following location C:\Python27\Lib\site-packages\pyttsx and here is a list of files,

 Name
 ----
 drivers
 driver.py
 driver.pyc
 engine.py
 engine.pyc
 voice.py
 voice.pyc
 __init__.py
 __init__.pyc

Since import of engine is failing, I am wondering if you have engine.py file in the correct folder or present at all.

For gtts:

I tried playing sound with winsound, but it did not work. Using pydub I was able to play the audio file. But, since your requirement is not to use a file, this may be a moot point.

import gtts
import winsound
from pydub import AudioSegment
from pydub.playback import play

blabla = ("my voice")
tts = gtts.gTTS(text=blabla, lang='en')
tts.save("rec.mp3")
print "Playing sound .."
#winsound.PlaySound("rec.wav", winsound.SND_FILENAME)
song = AudioSegment.from_mp3("rec.mp3")
play(song)

Hope this helps.

I'm using python2.7 on Ubuntu.

Try to replace "from engine import Engine" with "from .engine import Engine" in the engine module.It work for me!
