Python simple tutorial variable not defined issue

Question

So I was following a simple tutorial on youtube, and no matter what I do I keep getting the same issue.

Here is the code I used.

import speech_recognition as sr
import pyttsx3


voices = []
engine = pyttsx3.init()

voices = engine.getProperty('voices')
for voice in voices:
    print(voice.id)

I am writing this in sublimeText3. Everytime I build this, I get the same error.

File "C:\Users\This PC\Desktop\Py\introTest.py", line 14, in voices = engine.getProperty('voices') NameError: name 'engine' is not defined

Not sure why it is saying "engine" is not defined. I clearly have defined it under the try. Any help would be appreciated.

After removing the try/excepts I have a lot of new errors. Here is the build log.

Traceback (most recent call last): File "C:\Users\This PC\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pyttsx3__init__.py", line 44, in init eng = _activeEngines[driverName] File "C:\Users\This PC\AppData\Local\Programs\Python\Python37-32\lib\weakref.py", line 137, in getitem o = self.datakey KeyError: None

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "C:\Users\This PC\Desktop\Py\demo.py", line 7, in engine = pyttsx3.init() File "C:\Users\This PC\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pyttsx3__init__.py", line 46, in init eng = Engine(driverName, debug) File "C:\Users\This PC\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pyttsx3\engine.py", line 52, in init self.proxy = driver.DriverProxy(weakref.proxy(self), driverName, debug) File "C:\Users\This PC\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pyttsx3\driver.py", line 75, in init self._module = importlib.import_module(name) File "C:\Users\This PC\AppData\Local\Programs\Python\Python37-32\lib\importlib__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "", line 1006, in _gcd_import File "", line 983, in _find_and_load File "", line 967, in _find_and_load_unlocked File "", line 677, in _load_unlocked

Before the error occurs, does your code print "Import Issue" or "Runtime Issue"? — jwodder, Aug 23 '18 at 20:19
if your try statement fails, there is no engine. try declaring engine=None below voices — Scott Skiles, Aug 23 '18 at 20:20
That is the entire error log it does not print import or runtime issue. — KevinM1990112qwq, Aug 23 '18 at 20:23
@ScottSkiles I added that, now the attrib error is "NoneType" object has no attribute 'getProperty' — KevinM1990112qwq, Aug 23 '18 at 20:25
Ohh that being said, if engine is failing that means that pyttsx3 is not initializing right? — KevinM1990112qwq, Aug 23 '18 at 20:26
I suggest that you remove all `try/except` things, let the program fail, and post the actual error message. Perhaps it will explain why the engine fails to initialize. — DYZ, Aug 23 '18 at 20:29
@DYZ Ok, I am going to update my code, after removing the try/excepts I have a ton of no errors. I will show. — KevinM1990112qwq, Aug 23 '18 at 20:31

After seeing your full error log dump (without the try block hiding errors), in the last bit is the text:

line 3, in import win32com.client ModuleNotFoundError: No module named 'win32com' [Finished in 0.1s]

I would suggest looking at Jefferson Puchalski's answer again. (hint: it's telling you you're missing a module that pyttsx3 is dependant on)

You are attempting to assign engine = pyttsx3.init(), but when/if it fails, you then declare voices = engine.getProperty('voices'). But as the try block has failed, engine has not been declared.

Below, I assign engine = None, and skip the else form the try block; instead using a conditional to determine if it's None or not (it worked correctly on creating engine).

import speech_recognition as sr
import pyttsx3


voices = []
engine = None

try:
    engine = pyttsx3.init()
except ImportError:
    print('Import Issue')
except RuntimeError:
    print('Runtime Issue')

if (engine is not None):
    voices = engine.getProperty('voices')
    for voice in voices:
        print(voice.id)
else:
    print("Something went wrong")

Ok, after using your code. My build responds with the following — KevinM1990112qwq, Aug 23 '18 at 20:36

Try input the import in the try/catch block , and check if you got undefined after import, so throw exception. Looking in module official website, look your console logs for some of this erros,

Fixes for possible errors : No module named win32com.client No module named win32 No module named win32api

and try this

pip install pypiwin32

Addtiional show your logs to we understand better the situation!

This has nothing to do with the issue. I'm not sure where you picked those errors from? – roganjosh Aug 23 '18 at 20:23
I installed pypiwin32 and it solved the issue. It now displays the voices. Thanks @jefferson – KevinM1990112qwq Aug 23 '18 at 20:47

@roganjosh you see, i look he is using python on windows, so i deduced he need more than usual pypiwin libs. Long time programming :D – Jefferson Puchalski Aug 23 '18 at 20:57
@JeffersonPuchalski how do I install pypiwin32 with conda though? – KevinM1990112qwq Aug 23 '18 at 22:55
Activate the environment where you want to put the program. ex source env/bin/bash, Use pip or Anaconda prompt to install the pypiwin32 And ty import in python console or Anaconda prompt. – Jefferson Puchalski Aug 24 '18 at 01:42

import speech_recognition as sr
import pyttsx3

voices = [] 
try:
    engine = pyttsx3.init()
except ImportError:
    print('Requested driver is not found')
    engine = None
except RuntimeError:
    print('Driver fails to initialize')
    engine = None

if engine is None:
    print('Something went wrong')

else:
    voices = engine.getProperty('voices')
    for voice in voices:
        print(voice.id)

Hi I've faced a similar issue and this is how i managed to change voice with ease

import pyttsx3

voices = []

eng = pyttsx3.init()

voices = eng.getProperty('voice')

eng.setProperty('voice',voices[1].id)
eng.say("Some text here")
eng.runAndWait()
