type RecognitionConfig_AudioEncoding 

type RecognitionConfig_AudioEncoding int32

The encoding of the audio data sent in the request.

All encodings support only 1 channel (mono) audio.

For best results, the audio source should be captured and transmitted using a lossless encoding (`FLAC` or `LINEAR16`). The accuracy of the speech recognition can be reduced if lossy codecs are used to capture or transmit audio, particularly if background noise is present. Lossy codecs include `MULAW`, `AMR`, `AMR_WB`, `OGG_OPUS`, and `SPEEX_WITH_HEADER_BYTE`.

The `FLAC` and `WAV` audio file formats include a header that describes the included audio content. You can request recognition for `WAV` files that contain either `LINEAR16` or `MULAW` encoded audio. If you send `FLAC` or `WAV` audio file format in your request, you do not need to specify an `AudioEncoding`; the audio encoding format is determined from the file header. If you specify an `AudioEncoding` when you send send `FLAC` or `WAV` audio, the encoding configuration must match the encoding described in the audio header; otherwise the request returns an [google.rpc.Code.INVALID_ARGUMENT][google.rpc.Code.INVALID_ARGUMENT] error code.

`StreamingRecognizeResponse` is the only message returned to the client by `StreamingRecognize`. A series of zero or more `StreamingRecognizeResponse` messages are streamed back to the client. If there is no recognizable audio, and `single_utterance` is set to false, then no messages are streamed back to the client.

Here's an example of a series of ten `StreamingRecognizeResponse`s that might be returned while processing audio:

1. results { alternatives { transcript: "tube" } stability: 0.01 }

2. results { alternatives { transcript: "to be a" } stability: 0.01 }

  1. results { alternatives { transcript: "to be" } stability: 0.9 } results { alternatives { transcript: " or not to be" } stability: 0.01 }
  1. results { alternatives { transcript: "to be or not to be" confidence: 0.92 } alternatives { transcript: "to bee or not to bee" } is_final: true }

5. results { alternatives { transcript: " that's" } stability: 0.01 }

  1. results { alternatives { transcript: " that is" } stability: 0.9 } results { alternatives { transcript: " the question" } stability: 0.01 }
  1. results { alternatives { transcript: " that is the question" confidence: 0.98 } alternatives { transcript: " that was the question" } is_final: true }

Notes:

  • Only two of the above responses #4 and #7 contain final results; they are indicated by `is_final: true`. Concatenating these together generates the full transcript: "to be or not to be that is the question".
  • The others contain interim `results`. #3 and #6 contain two interim `results`: the first portion has a high stability and is less likely to change; the second portion has a low stability and is very likely to change. A UI designer might choose to show only high stability `results`.
  • The specific `stability` and `confidence` values shown above are only for illustrative purposes. Actual values may vary.
  • In each response, only one of these fields will be set: `error`, `speech_event_type`, or one or more (repeated) `results`.
