Expand description
Provides information to the recognizer that specifies how to process the request.
Fields
encoding: i32
Encoding of audio data sent in all RecognitionAudio
messages.
This field is optional for FLAC
and WAV
audio files and required
for all other audio formats. For details, see [AudioEncoding][google.cloud.speech.v1.RecognitionConfig.AudioEncoding].
sample_rate_hertz: i32
Sample rate in Hertz of the audio data sent in all
RecognitionAudio
messages. Valid values are: 8000-48000.
16000 is optimal. For best results, set the sampling rate of the audio
source to 16000 Hz. If that’s not possible, use the native sample rate of
the audio source (instead of re-sampling).
This field is optional for FLAC and WAV audio files, but is
required for all other audio formats. For details, see [AudioEncoding][google.cloud.speech.v1.RecognitionConfig.AudioEncoding].
audio_channel_count: i32
The number of channels in the input audio data.
ONLY set this for MULTI-CHANNEL recognition.
Valid values for LINEAR16 and FLAC are 1
-8
.
Valid values for OGG_OPUS are ‘1’-‘254’.
Valid value for MULAW, AMR, AMR_WB and SPEEX_WITH_HEADER_BYTE is only 1
.
If 0
or omitted, defaults to one channel (mono).
Note: We only recognize the first channel by default.
To perform independent recognition on each channel set
enable_separate_recognition_per_channel
to ‘true’.
enable_separate_recognition_per_channel: bool
This needs to be set to true
explicitly and audio_channel_count
> 1
to get each channel recognized separately. The recognition result will
contain a channel_tag
field to state which channel that result belongs
to. If this is not true, we will only recognize the first channel. The
request is billed cumulatively for all channels recognized:
audio_channel_count
multiplied by the length of the audio.
language_code: String
Required. The language of the supplied audio as a [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tag. Example: “en-US”. See Language Support for a list of the currently supported language codes.
max_alternatives: i32
Maximum number of recognition hypotheses to be returned.
Specifically, the maximum number of SpeechRecognitionAlternative
messages
within each SpeechRecognitionResult
.
The server may return fewer than max_alternatives
.
Valid values are 0
-30
. A value of 0
or 1
will return a maximum of
one. If omitted, will return a maximum of one.
profanity_filter: bool
If set to true
, the server will attempt to filter out
profanities, replacing all but the initial character in each filtered word
with asterisks, e.g. “f***”. If set to false
or omitted, profanities
won’t be filtered out.
speech_contexts: Vec<SpeechContext>
Array of [SpeechContext][google.cloud.speech.v1.SpeechContext]. A means to provide context to assist the speech recognition. For more information, see speech adaptation.
enable_word_time_offsets: bool
If true
, the top result includes a list of words and
the start and end time offsets (timestamps) for those words. If
false
, no word-level time offset information is returned. The default is
false
.
enable_automatic_punctuation: bool
If ‘true’, adds punctuation to recognition result hypotheses. This feature is only available in select languages. Setting this for requests in other languages has no effect at all. The default ‘false’ value does not add punctuation to result hypotheses. Note: This is currently offered as an experimental service, complimentary to all users. In the future this may be exclusively available as a premium feature.
diarization_config: Option<SpeakerDiarizationConfig>
Config to enable speaker diarization and set additional parameters to make diarization better suited for your application. Note: When this is enabled, we send all the words from the beginning of the audio for the top alternative in every consecutive STREAMING responses. This is done in order to improve our speaker tags as our models learn to identify the speakers in the conversation over time. For non-streaming requests, the diarization results will be provided only in the top alternative of the FINAL SpeechRecognitionResult.
metadata: Option<RecognitionMetadata>
Metadata regarding this request.
model: String
Which model to select for the given request. Select the model best suited to your domain to get best results. If a model is not explicitly specified, then we auto-select a model based on the parameters in the RecognitionConfig.
Model | Description |
command_and_search |
Best for short queries such as voice commands or voice search. |
phone_call |
Best for audio that originated from a phone call (typically recorded at an 8khz sampling rate). |
video |
Best for audio that originated from from video or includes multiple speakers. Ideally the audio is recorded at a 16khz or greater sampling rate. This is a premium model that costs more than the standard rate. |
default |
Best for audio that is not one of the specific audio models. For example, long-form audio. Ideally the audio is high-fidelity, recorded at a 16khz or greater sampling rate. |
use_enhanced: bool
Set to true to use an enhanced model for speech recognition.
If use_enhanced
is set to true and the model
field is not set, then
an appropriate enhanced model is chosen if an enhanced model exists for
the audio.
If use_enhanced
is true and an enhanced version of the specified model
does not exist, then the speech is recognized using the standard version
of the specified model.
