Google 语音 API，选项 [phrases] 使用

Question

我尝试使用 'phrases' 属性添加额外的单词以供 Google API 识别。当我在我的请求中设置它们时，我收到一条错误消息。我收到带有此错误的响应 400："Invalid JSON payload received. Unknown name \"speech_contexts\": 找不到字段。",

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。负载应该看起来像这样：

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