Not working pyttsx3 with python 3.11.4

[Fledermaus-20]

I own a macbook air m2 16 gb ram and 512gb storage mac os 13.5 python v. 3.11.4

Found the solution on SO - you need to replace the faulty line (nsss.py:15) by this:

self = objc.super(NSSpeechDriver, self).init()

Also make sure that pyobjc is installed as a dependency.

This fixed it for me, though I'm facing a different issue now: after speaking, the script/app exits.

Is that the same issue what you hvae found? Python[11740:160581] -[OC_BuiltinPythonArray hasPrefix:]: unrecognized selector sent to instance 0x11c10d270

Wow. Just saw this. Do you mean it exits without any error or status code whatever? Because as soon as it talked in my case it just terminates without any info. I also edited the nsss.py file.

I tried to trace it down and it seems that in the file /Users/username/miniconda3/envs/test/lib/python3.10/sitepackages/PyObjCTools/AppHelper.py

def runConsoleEventLoop(
    argv=None, installInterrupt=False, mode=NSDefaultRunLoopMode, maxTimeout=3.0
):
    if argv is None:
        argv = sys.argv
    if installInterrupt:
        installMachInterrupt()
    runLoop = NSRunLoop.currentRunLoop()
    stopper = PyObjCAppHelperRunLoopStopper.alloc().init()
    PyObjCAppHelperRunLoopStopper.addRunLoopStopper_toRunLoop_(stopper, runLoop)
    try:
        while stopper.shouldRun():
            print("shouldRun " + str(stopper.shouldRun()))
            nextfire = runLoop.limitDateForMode_(mode)
            if not stopper.shouldRun():
                print("stopper.shouldRun() is false")
                break
            soon = NSDate.dateWithTimeIntervalSinceNow_(maxTimeout)
            if nextfire is not None:
                nextfire = soon.earlierDate_(nextfire)
                print("nextfire")
            if not runLoop.runMode_beforeDate_(mode, nextfire):
                print("runloop stopped")
                print(runLoop.runMode_beforeDate_(mode, nextfire))
                stopper.stop()
        print("done")
    finally:
        print("finally")
        PyObjCAppHelperRunLoopStopper.removeRunLoopStopperFromRunLoop_(runLoop)

This code never prints finally, runloop stopped, stopper.shouldRun() is false nor done. The output is just:

shouldRun True
nextfire
shouldRun True
nextfire
shouldRun True
nextfire

And then it seems to abruptly terminate. However, if we would exit the while loop correctly we would print the done.

EDIT: As stated in #279 downgrading to pyobjc 9.0.1 works like a charm. Maybe it also solves your issue @essenciary

[essenciary]

@m1guelperez Yes, indeed, it just exited without any info/output, practically crashing the app.

I did manage to make it work by downgrading, but then I ran into another issue when attempting to save as audio files: the audio file was generated but was always the same size (I think 16KB) and empty.

I was running the script on an M2 aarm mac.

This solved it finally for me #297
