谷歌语音API，选项[短语]使用

Question

我尝试使用“短语”属性来添加要被Google识别的额外单词。当我在请求中设置它们时，我会收到一条错误消息。我收到响应400与此错误：“无效的JSON有效载荷收到。未知的名称\"speech_contexts\"：无法找到字段。

有人知道为什么吗？

我认为您需要将speechContexts参数作为config结构的一部分。有效载荷应该如下所示：

{
  "audio": {
    "content": "UklGRiSWAABXQVZFZm10IBAAAAABAAEAQ...B8AAIA+AAACABAAZGF0YQCWAAAAAAAAA="
  },
  "config": {
    "encoding": "LINEAR16",
    "languageCode": "en-US",
    "sampleRateHertz": "8000",
    "speechContexts": {
      "phrases": [
        "borja"
      ]
    }
  }
}
