Your answer helped me a lot. Thanks to you, I was able to get Siri to speak. I will post this question once again elsewhere.

@ccc Thank you for making that. But just select just one voice that contains siri_O-ren_en-JP ...

@cvp It will eventually be used to read out the e-book; once one episode is read out, the next episode must be read out. It is not a good idea to read everything and run a 10,000 word readout.

I successfully got Siri to speak any string of text I wanted, but ran into the following problem.
When I run the reading multiple times, the voices overlap.
It seems that the next reading is performed without waiting for the reading to finish.

I learned that to wait for this I need to use the AVSpeechSynthesizerDelegate , but that is too difficult for me to use.
Can anyone help?

from objc_util import *

txt = ['こんにちは', '私はSiriです。']

AVSpeechUtterance=ObjCClass('AVSpeechUtterance')
AVSpeechSynthesizer=ObjCClass('AVSpeechSynthesizer')
AVSpeechSynthesisVoice=ObjCClass('AVSpeechSynthesisVoice')

voices=AVSpeechSynthesisVoice.speechVoices()
for i in range(0,len(voices)):
    #print(i,voices[i].language(),voices[i].identifier())
    
    if 'ja-JP' in str(voices[i].identifier()): # if u have Japanese Siri voice, replace from 'ja-JP' to 'siri_O-ren_ja-JP'
        vi = i
        break

for t in txt:    
    utterance=AVSpeechUtterance.speechUtteranceWithString_(t)
    utterance.rate = 0.5
    utterance.useCompactVoice=False
    utterance.voice = voices[vi]

    synthesizer=AVSpeechSynthesizer.new()
    synthesizer.speakUtterance_(utterance)```

Can I update Jedi？

@cvp I can hear Siri-voice use this script!
But I don't understand how to use Siri-voice in my script...
speech module can speak one line, but this script is over 200 lines...

Now I tried, but the issue is still there...

I can’t see Autocomplete when using Type Hint.

class Foo():
    def __init__(self):
        self.bar = 'a'
foo = Foo()
foo.# I can get Autocomplete

class Foo():
    def __init__(self):
        self.bar: str = 'a'
foo = Foo()
foo.# There are No Autocomplete

Can I fix it immediately some way? Or Need update from omz?

For the 4 voices, I guessed this was Female, Male, Sir Female, Siri Male . However, since they are all 'ja-JP', they are indistinguishable.

Is there a way to use the Siri voice from the speech module? I'm Japanese so I got the speech containing JP with speech.get_synthesis_languages() but it's ['ja-JP', 'ja-JP', 'ja-JP', 'ja-JP'] was. There should be a Siri voice in it, is there a way to identify it and use it?
