408 请求超时 Microsoft Speech to Text

我的 .wav 文件长度只有 4 秒。即使多次重试并在云上运行后，我仍然不断收到以下错误

  * upload completely sent off: 12 out of 12 bytes
  < HTTP/1.1 408 Request timed out (> 14000 ms)

有人遇到过这个问题吗？ 这是我的要求

  `curl -v "https://speech.platform.bing.com/recognize?

  "Authorization: Bearer $1" -H "Content-Type: audio/wav; samplerate=8000" -- 
  data-binary $2`

我在让它工作时也遇到了一些问题。以下 BASH 脚本“bingrec.sh”可能有助于使其更加清晰；输入您的 SUBSCRIPTION_KEY 并根据需要调整 SAMPLERATE 等。正如其他人指出的那样，区域设置和场景需要设置为支持的值，并且 instance_id 和 request_id 需要采用 GUID 格式。音频文件长度应小于 10 秒，采样率为 8000 或 16000。此外，curl“--data-binary”参数要求音频文件名前面有一个“@”。
