# import Os module to start the audio file

myobj = gTTS(text=mytext, lang=language, slow=False) 
myobj.save("output.mp3")

        engine.setProperty('voice', voice.id)
        break

# Adjust the rate (speed of speech) and volume
engine.setProperty('rate', 150)  # Speed of speech
engine.setProperty('volume', 1.0)  # Volume level between 0 and 1

# Create a temporary file to save the audio output
with tempfile.NamedTemporaryFile(delete=False, suffix='.wav') as temp_audio_file:
    temp_audio_path = temp_audio_file.name

# Save speech to the temporary WAV file
engine.save_to_file(mytext, temp_audio_path)
engine.runAndWait()

# Convert the WAV file to MP3 using pydub
sound = AudioSegment.from_wav(temp_audio_path)
sound.export("output.mp3", format="mp3")

print("Audio saved as output.mp3")
