5 months ago It has to do with your file format, switch it to .wav or even better .aiff instead of .mp3
Long story: This library uses NSSpeechSynthesizer (deprecated) for macOS to save the audio into a file
By default, it synthesizes the text into an AIFF file format, per the docs that's the only format it supports.
Since both .wav and .aiff formats follow the same type of encoding (with difference in file size though), you may most likely be able to generate .wav but NSSpeechSynthesizer DOES NOT support or recognize mp3 files
Remember NSSpeechSynthesizer class in macOS is specifically designed for speech synthesis and text-to-speech functionality. It is not intended for MP3 files.
With that said, the current library has many short comings specific to latest versions of macOS. I had multiple PRs that went stale. I tried to reach out to Natesh (the author) several times to get my PR merged. Due to lack of response, I created a spin off library py3-tts with fixes for all the things macOS decided to change after Catalina
So far, the major issues that's been fixed in py3-tts are:
KeyErrorin case of missing voice attributes- Unable to override
NSSpeechDriver - Missing proxy status when saving to file - especially problematic with M1s due to their System on Chip design (basically speed)
Hope this helps
Hi! I'm using pyttsx3 in one of my projects, and I'm testing the library in a separate python file. More specifically, I'm trying to save the speech as an mp3 file. This is what I have.
import pyttsx3 as tts
engine = tts.init() engine.setProperty('rate', 180) engine.setProperty('volume', 0.9)
voices = engine.getProperty('voices')
engine.setProperty('voice', voices[30].id)
engine.save_to_file("Hello. This is a test.", 'test.mp3') engine.runAndWait()
What I've noticed, however, is that nothing ever actually happens. The speech works perfectly fine; it's saving it as a file that's an issue. I don't get any errors while this script is running; it just runs forever :(
Any help is appreciated!
I'm on MacOS Sonoma 14.0
