engine.save_to_file() produces empty file

[angoodkind]

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+)

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?

[bearcatjamboree]

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

[egorgam]

I found a small hack to fix it #267. Maybe someone can found better solution to fix it right 🥲

[nateshmbhat]

fixed in #271

CentOS 7 (yeah, I know, it's old)

This code

import pyttsx3
engine = pyttsx3.init() # object creation
engine.save_to_file('Hello World', 'test.mp3')
engine.runAndWait()

or this code (wav)

import pyttsx3
engine = pyttsx3.init() # object creation
engine.save_to_file('Hello World', 'test.wav')
engine.runAndWait()

Produce empty files for me. They have relevant headers for mp3 file or wav file, but nothing else.
