I am a person who pursues quality. There are a lot of tts available, and there are also a lot of free ones, but Microsoft is currently the only one in the world, and the tts website seems to have canceled the free prostitution mechanism recently. Using an account is not expensive, 40 a year.
The simple method of use is here, of course, is the homework copied from the Microsoft document:
it is known that it can be read directly through the speaker, of course, it can also be converted into audio files in various formats and downloaded. Genuine users are comfortable

import azure.cognitiveservices.speech as speechsdk

# This example requires environment variables named "SPEECH_KEY" and "SPEECH_REGION"

audio_config = speechsdk.audio.AudioOutputConfig(use_default_speaker=True)

# The language of the voice that speaks.
speech_config.speech_synthesis_voice_name='zh-CN-XiaochenNeural'

speech_synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config, audio_config=audio_config)

# Get text from the console and synthesize to the default speaker.
print("gogogo")
