Boost tuning

Learn how to improve transcription with multiple boost values.

Separate boost values

NOTE: The boost feature is currently in beta.

Recall that speechContexts is a list of dictionaries. Because it is a list, more than one dictionary with phrases and boost can be defined.

"config": {
    "encoding":"LINEAR16",
    "sampleRateHertz": 8000,
    "languageCode":"en-US",
    "speechContexts": [{
      "phrases": ["fair"],
      "boost": 15
     }, {
      "phrases": ["fare"],
      "boost": 2
     }]
  }
