}

A phrases containing words and phrase "hints" so that the speech recognition is more likely to recognize them. This can be used to improve the accuracy for specific words and phrases, for example, if specific commands are typically spoken by the user. This can also be used to add additional words to the vocabulary of the recognizer. See [usage limits](https://cloud.google.com/speech-to-text/quotas#content).

List items can also include pre-built or custom classes containing groups of words that represent common concepts that occur in natural language. For example, rather than providing a phrase hint for every month of the year (e.g. "i was born in january", "i was born in febuary", ...), use the pre-built `$MONTH` class improves the likelihood of correctly transcribing audio that includes months (e.g. "i was born in $month"). To refer to pre-built classes, use the class' symbol prepended with `$` e.g. `$MONTH`. To refer to custom classes that were defined inline in the request, set the class's `custom_class_id` to a string unique to all class resources and inline classes. Then use the class' id wrapped in $`{...}` e.g. "${my-months}". To refer to custom classes resources, use the class' id wrapped in `${}` (e.g. `${my-months}`).

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, unless the `audio_channel_count` and `enable_separate_recognition_per_channel` fields are set.

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`, `SPEEX_WITH_HEADER_BYTE`, and `MP3`.

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 }

3. results { alternatives { transcript: "to be" } stability: 0.9 }

results { alternatives { transcript: " or not to be" } stability: 0.01 }

4. 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 }

6. results { alternatives { transcript: " that is" } stability: 0.9 }

results { alternatives { transcript: " the question" } stability: 0.01 }

7. 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`.
