the problem is that the memory stream has no wav header. i have not think it clear that we need a memory with header or not. so , for the current solution, we can add the wav header for your problem like that below.
@Gary2018X
import pyttsx4
from io import BytesIO
from pydub import AudioSegment
from pydub.playback import play
import os
import sys
engine = pyttsx4.init()
b = BytesIO()
engine.save_to_file('i am Hello World', b)
engine.runAndWait()
#the bs is raw data of the audio.
bs=b.getvalue()
# add an wav file format header
b=bytes(b'RIFF')+ (len(bs)+38).to_bytes(4, byteorder='little')+b'WAVEfmt\x20\x12\x00\x00' \
b'\x00\x01\x00\x01\x00' \
b'\x22\x56\x00\x00\x44\xac\x00\x00' +\
b'\x02\x00\x10\x00\x00\x00data' +(len(bs)).to_bytes(4, byteorder='little')+bs
# changed to BytesIO
b=BytesIO(b)
audio = AudioSegment.from_file(b, format="wav")

looks like this feature works only with sapi5 engine (on Windows machines)
@egorgam yes you are right. it currently support only sapi5 engine. which engine do you want to add this feature?
Thanks.
@egorgam make a new feature request issue to describe you problem if you want another engine support.
@egorgam espeak engine is supposed to be supported by the current version(3.0.5). but it is not tested. you can try if you like
After using the save to bytes method you developed, I wanted to use pydub loading for some post-processing, but it reported an error in format. How can I solve it?
