如何在 Python 中使用 Google 的文字转语音 API

Question

我的密钥已准备就绪，可以发出请求并从 Google 的文本中获取语音。
我尝试了这些命令以及更多命令。
这些文档没有提供我发现的 Python 入门的直接解决方案。我不知道我的 API 键与 JSON 和 URL

放在一起

One solution in their docs here is for CURL.。但是涉及在必须发送回他们以获取文件的请求之后下载一个 txt。有没有办法在 Python 中执行此操作而不涉及我必须 return 他们的 txt？ 我只想将我的字符串列表 return 编辑为音频文件。

（我把我的实际密钥放在上面的块中。我只是不打算在这里分享它。）

Answer 1

找到答案并在我打开的 150 Google 个文档页面中丢失了 link。

#(Since I'm using a Jupyter Notebook)
import os
os.environ["GOOGLE_APPLICATION_CREDENTIALS"]="/Path/to/JSON/file/jsonfile.json"
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"')

我费时的追求是尝试通过 JSON 和 Python 发送请求，但这似乎是通过它们自己的模块，效果很好。 注意默认语音性别是 'neutral'.

为 JSON 文件配置 Python 应用程序并安装客户端库

1. 创建服务帐户
2. 使用服务帐户创建服务帐户密钥here
3. JSON 文件下载并安全保存
4. 在您的 Python 应用程序中包含 Google 应用程序凭据
5. 安装库：pip install --upgrade google-cloud-texttospeech

使用 Google 的 Python 示例发现： https://cloud.google.com/text-to-speech/docs/reference/libraries 注意：在 Google 的示例中，它没有正确包含名称参数。 和 https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/texttospeech/cloud-client/quickstart.py

以下是使用 google 应用凭据和女性 wavenet 语音对示例进行的修改。

os.environ["GOOGLE_APPLICATION_CREDENTIALS"]="/home/yourproject-12345.json"

from google.cloud import texttospeech

# Instantiates a client
client = texttospeech.TextToSpeechClient()

# Set the text input to be synthesized
synthesis_input = texttospeech.types.SynthesisInput(text="Do no evil!")

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

# 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"')

语音、姓名、语言代码、SSML 性别等

语音列表：https://cloud.google.com/text-to-speech/docs/voices

在上面的代码示例中，我从 Google 的示例代码中更改了语音，以包含名称参数并使用 Wavenet 语音（改进很多但​​价格更高，每百万个字符 16 美元）和 SSML 性别给女性。

voice = texttospeech.types.VoiceSelectionParams(
        language_code='en-US',
        name='en-US-Wavenet-C',
        ssml_gender=texttospeech.enums.SsmlVoiceGender.FEMALE)

如果您想避免使用 google Python API，您可以简单地这样做：

import requests 
import json

url = "https://texttospeech.googleapis.com/v1beta1/text:synthesize"

text = "This is a text"

data = {
        "input": {"text": text},
        "voice": {"name":  "fr-FR-Wavenet-A", "languageCode": "fr-FR"},
        "audioConfig": {"audioEncoding": "MP3"}
      };

headers = {"content-type": "application/json", "X-Goog-Api-Key": "YOUR_API_KEY" }

r = requests.post(url=url, json=data, headers=headers)
content = json.loads(r.content)

这与您所做的类似，但您需要包含 API 密钥。
