Python 文字转语音免费

要在 Python 中进行文字转语音，你可以使用 Google Text-to-Speech API。Google Text-to-Speech API 允许你通过提供一个文本字符串来生成一个音频文件，该音频文件可以是 WAV 或 MP3 格式。

以下是一个简单的 Python 代码示例，演示如何使用 Google Text-to-Speech API 将文本转换为语音：

from google.cloud import texttospeech

# Replace with your Google Cloud project ID
project_id = 'your-project-id'

# Create the Text-to-Speech client
client = texttospeech.TextToSpeechClient()

# Set the text input to be synthesized
synthesis_input = texttospeech.SynthesisInput(text='Hello, world!')

# Build the voice request
voice = texttospeech.VoiceSelectionParams(
    language_code='en-US',
    name='en-US-Wavenet-D'
)

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

# Perform the text-to-speech request
response = client.synthesize_speech(
    input=synthesis_input,
    voice=voice,
    audio_config=audio_config
)

# Save the audio file
with open('output.mp3', 'wb') as out:
    out.write(response.audio_content)
    print('Audio content written to file "output.mp3"')

请注意，使用 Google Text-to-Speech API 需要你拥有一个 Google Cloud Platform 帐号，并且需要设置适当的身份验证和授权。Google 提供了一定的免费配额，但在超出免费配额后，你可能需要支付一定的费用。
