Question

我尝试使用python 3.7在我的window 10计算机上的Google TTS中运行一个示例，但是它不起作用。我已经将每一步设置为官方页面https://cloud.google.com/text-to-speech/docs/quickstart-client-libraries，但是当我将python文件作为页面中的示例运行时，它失败了。

示例代码如下：文件名：ggtts.py

"""Synthesizes speech from the input string of text or ssml.

Note: ssml must be well-formed according to:
    https://www.w3.org/TR/speech-synthesis/
"""
from google.cloud import texttospeech

# Instantiates a client
client = texttospeech.TextToSpeechClient()

# Set the text input to be synthesized
synthesis_input = texttospeech.types.SynthesisInput(text="Hello, World!")

# Build the voice request, select the language code ("en-US") and the ssml
# voice gender ("neutral")
voice = texttospeech.types.VoiceSelectionParams(
    language_code='en-US',
    ssml_gender=texttospeech.enums.SsmlVoiceGender.NEUTRAL)

# Select the type of audio file you want returned
audio_config = texttospeech.types.AudioConfig(
    audio_encoding=texttospeech.enums.AudioEncoding.MP3)

# Perform the text-to-speech request on the text input with the selected
# voice parameters and audio file type
response = client.synthesize_speech(synthesis_input, voice, audio_config)

# The response's audio_content is binary.
with open('output.mp3', 'wb') as out:
    # Write the response to the output file.
    out.write(response.audio_content)
    print('Audio content written to file "output.mp3"')

以下错误：

Traceback (most recent call last):
  File "D:\Program Files\Python\Python37\lib\site-packages\google\api_core\grpc_helpers.py", line 57, in error_remapped_callable
    return callable_(*args, **kwargs)

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "D:\files\mypyfile\ggtts.py", line 26, in <module>
    response = client.synthesize_speech(synthesis_input, voice, audio_config)

  File "<string>", line 3, in raise_from
google.api_core.exceptions.DeadlineExceeded: 504 Deadline Exceeded
>>>

错误似乎来自

response = client.synthesize_speech(synthesis_input, voice, audio_config)

我是Google API的新手，不熟悉他们的代码，请有人帮忙，谢谢

Google语音测试无法正常工作，错误：google.api_core.exceptions.DeadlineExceeded：超过504个截止日期
