Text to Speech in Python

vegaseat 1 Tallied Votes 2K Views Share

Yes, you can let your computer read text to you. The task is relatively easy, if you have Windows on your machine. All you need is Microsoft's speech-API SAPI, the Python Text to Speech module pyTTS, and an updated version of win32com, all free downloads. Here are some experiments with the pyTTS module that literally talk to you.

# 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
print "Voice is set ot MSMary"


# announce the date and time, does a good job
timeStr = "The date and time is " + time.asctime()
print timeStr


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('Haah haa haah haa')

Can be shaped into a very helpful tool for any blind person you know!

impressive...*has never used python b4* i like it alot!:cheesy:

I typed it in, got no errors, but no sound or verification that it worked either...

Generally you would copy and paste the code into a Python editor like IDLE or DrPython and then run it from there. The sound does use the sound chip and external speaker system of the PC.

hello there dude...very good tutorial and inspiring for more projects using pyTTS...but i have a problem...when typing pyTTS.Create() , a ValueError exception is raised : "SAPI not supported" , i have windows xp sp2 , python 2.5 , and installed the first two packages you listed , plus microsoft voices , but still get the same error message , what do you recommend ?

A somewhat updated version:

''' pyttsx_speech_test102.py

speaks the present time in English, for instance
"Sat Apr 27 15:10:59"
"Saturday April 27th 15 hours 10 minutes and 59 seconds" 


also needs

install setuptools first then
unpack the tar file and run (using Python27)
setup.py install
it installs 

info at

tested with Python273 in Windows7 (has the SAPI speech engine installed)

import pyttsx
import time

engine = pyttsx.init()
# speech rate in words per minute
engine.setProperty('rate', 100)
# volume 0.0 to 1.0
engine.setProperty('volume', 0.9)

now_tuple = time.localtime()
#print(now_tuple)  # test

# slice off the year
now_str = time.asctime(now_tuple)[:-4]
print(now_str)  # test

Thanks Henri, module pyttsx is somewhat complicated to install, but works well.
Doesn't seem to work with Python3?
