谷歌文本到语音api无法找到json密钥的路径使用anaconda和python在windows上

Question

我正在尝试使用google clould api来使用文本到语音。为此，它需要访问我保存到的json密钥

C:keys*****.json

并将路径设置为

set GOOGLE_APPLICATION_CREDENTIALS="C:keys*****.json"

当我运行示例scrip时，我得到一个错误，即我无法在该路径上找到文件。

我使用anaconda(作为管理员(和python来设置anaconda终端中的变量。我也试着在windows cmd中设置它(用相同的命令设置(，但没有成功。

我也张贴了纸条，以防你想测试它：

def synthesize_text(text):
"""Synthesizes speech from the input string of text."""
from google.cloud import texttospeech
client = texttospeech.TextToSpeechClient()
#text = "Hello world"
input_text = texttospeech.types.SynthesisInput(text=text)
#input_text = texttospeech.types.SynthesisInput(text="Hellow world")
# Note: the voice can also be specified by name.
# Names of voices can be retrieved with client.list_voices().
voice = texttospeech.types.VoiceSelectionParams(
language_code='en-US',
ssml_gender=texttospeech.enums.SsmlVoiceGender.FEMALE)
audio_config = texttospeech.types.AudioConfig(
audio_encoding=texttospeech.enums.AudioEncoding.MP3)
response = client.synthesize_speech(input_text, voice, audio_config)
# The response's audio_content is binary.
with open('output.mp3', 'wb') as out:
out.write(response.audio_content)
print('Audio content written to file "output.mp3"')

synthesize_text("hello world")

我只需要删除引号并进行

set GOOGLE_APPLICATION_CREDENTIALS=C:keys******.json

它奏效了。
