google-text-to-speech - Google Cloud Text-to-Speech 请求的最大大小

Question

当我提交对太长文本的综合请求时，我收到以下错误:

google.api_core.exceptions.ResourceExhausted: 429 Received message larger than max (X vs. 4194304)

其中“X”是返回请求的字节大小。为什么请求限制为 4MB？我知道 requests are limited to 5000 characters ，但我的请求是 ~1500 个字符，远不及限制。是否可以接收大于 4MB 的消息？或者 5000 个字符的限制不是 Google 文字转语音的真正瓶颈？

如果它有任何改变，我将使用不同的 en-us Wavenet 声音和 LINEAR16 编码。

这是一个对我有用的编程修复(Python)(如此 GitHub 帖子中所提议的:https://github.com/googleapis/python-texttospeech/issues/5#issuecomment-709562585)

from google.cloud import texttospeech_v1
from google.cloud.texttospeech_v1.services.text_to_speech.transports.grpc import (
    TextToSpeechGrpcTransport,
)

channel = TextToSpeechGrpcTransport.create_channel(
    options=[("grpc.max_receive_message_length", 24 * 1024 * 1024)]
)
transport = TextToSpeechGrpcTransport(channel=channel)
client = texttospeech_v1.TextToSpeechClient(transport=transport)
