In using pyttsx3 to produce mp3 audio files, it seems there's a problem that the mp3 file is not recognizable by pydub.
pyttsx3: text to speech package pydub: audio handling package
The error message says a lot of "Header missing".
The code is below.
What went wrong, and how can it be corrected?
import pyttsx3
engine = pyttsx3.init("sapi5")
engine.setProperty('rate', 130) # number higher the faster
voices = engine.getProperty("voices")
engine.setProperty("voice", voices[0].id)
texts = "a quick sentence into mp3"
engine.save_to_file(texts, "C:\\TEM\\temp audio.mp3")
engine.runAndWait()
# the produced file plays no problem by media player in Windows.
# here to read the mp3 audio file produced
from pydub import AudioSegment
sound1 = AudioSegment.from_file(r"C:\\TEM\\temp audio.mp3", format="mp3") # error pops here
Error message is here:
