pyttsx3

pyttsx3 copied to clipboard

In running the code below, engine.say() works fine. However, when I save the audio to a file, the file is empty. I have also verified this in sox.

I am running pyttsx3 on a Macbook running OS 10.15.6.

import pyttsx3
engine = pyttsx3.init()
engine.say("I will speak this text") # successfully produced
engine.setProperty('volume',1.0)
volume = engine.getProperty('volume') 
print(volume)  # prints 1
engine.save_to_file('Hello World', 'test.mp3')
engine.runAndWait()
# engine.stop()

Hi, Any updates on this? Thanks!

save_to_file seems to work in interactive mode but not in scripting mode.

$ python3
>>> import pyttsx3; engine = pyttsx3.init(); engine.save_to_file('Hello world', 'tmp.mp3'); engine.runAndWait();

Works as expected. But the following two ways don't work (they don't even create an empty file) (I am using Ubuntu 18.04).

$ python3 -c "import pyttsx3; engine = pyttsx3.init(); engine.save_to_file('Hello world', 'tmp.mp3'); engine.runAndWait();" 
$ python3 main.py 

where main.py is as follows:

import pyttsx3
engine = pyttsx3.init()
engine.save_to_file('Hello world', 'tmp.mp3')
engine.runAndWait()

Note that engine.say() is working (for me) in all three ways of invoking python.

Looking forward to any updates.

I also got empty file when saving to ".mp3", but simply changing to ".aiff" resolved my issue.

According to Apple's documentation, NSSpeechSynthesizer synthesizes text into a sound (AIFF) file, so ".aiff" should be the supported format. (macOS 10.3+) https://developer.apple.com/documentation/appkit/nsspeechsynthesizer/1448394-startspeakingstring?language=objc

what about windows? I did the same thing with windows and it just saved nothing

me too，but in myself computer Normal operation ，Cloud computer make empty file，the cloud computer does not have a graphics card installed。Windows 10 system installed on cloud computer，can you help me.

That solved my problem! Thanks!

For me (on macOS) it is able to create / save a .wav or .aiff file, but these are not readable / playable

I have the same problem, did you manage to fix it?

The same problem with mac, works on windows tho. Did you solve it?

This still produces empty files on mac, whether you use .wav, .mp3, or .aiff. Anyone know a way to fix this?

I found a small hack to fix it https://github.com/nateshmbhat/pyttsx3/pull/267. Maybe someone can found better solution to fix it right 🥲
