google text to speech api无法在windows上使用anaconda和python找到json key的路径

from google.cloud import texttospeech

# 设置JSON key的路径
key_path = 'path/to/your/json/key.json'

# 创建Text-to-Speech客户端
client = texttospeech.TextToSpeechClient.from_service_account_json(key_path)

# 构建文本输入
text_input = texttospeech.SynthesisInput(text='Hello, world!')

# 设置语音参数
voice = texttospeech.VoiceSelectionParams(
    language_code='en-US',
    ssml_gender=texttospeech.SsmlVoiceGender.NEUTRAL
)

# 设置音频输出格式
audio_config = texttospeech.AudioConfig(
    audio_encoding=texttospeech.AudioEncoding.MP3
)

# 调用API进行语音合成
response = client.synthesize_speech(
    input=text_input,
    voice=voice,
    audio_config=audio_config
)

# 将合成的语音保存到文件
with open('output.mp3', 'wb') as out:
    out.write(response.audio_content)
    print('Audio content written to file "output.mp3"')
