Google Speech API, the option [phrases] using

Question

I try to use the 'phrases' property to add extra words to be recognized by the Google API. When I set them in my request, I receive an error message. I receive the response 400 with this error : "Invalid JSON payload received. Unknown name \"speech_contexts\": Cannot find field.",

Do someone know why ?

I think you need to include the speechContexts argument as part of the config structure. The payload should look something like this instead:

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