Available on crate features conversation-profiles or conversations only.

Configures speech transcription for ConversationProfile.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

speech_model_variant: SpeechModelVariant

The speech model used in speech to text. SPEECH_MODEL_VARIANT_UNSPECIFIED, USE_BEST_AVAILABLE will be treated as USE_ENHANCED. It can be overridden in AnalyzeContentRequest and StreamingAnalyzeContentRequest request. If enhanced model variant is specified and an enhanced version of the specified model for the language does not exist, then it would emit an error.

model: String

Which Speech model to select. Select the model best suited to your domain to get best results. If a model is not explicitly specified, then Dialogflow auto-selects a model based on other parameters in the SpeechToTextConfig and Agent settings. If enhanced speech model is enabled for the agent and an enhanced version of the specified model for the language does not exist, then the speech is recognized using the standard version of the specified model. Refer to Cloud Speech API documentation for more details. If you specify a model, the following models typically have the best performance:

• phone_call (best for Agent Assist and telephony)
• latest_short (best for Dialogflow non-telephony)
• command_and_search

Leave this field unspecified to use Agent Speech settings for model selection.

phrase_sets: Vec<String>

List of names of Cloud Speech phrase sets that are used for transcription. For phrase set limitations, please refer to Cloud Speech API quotas and limits.

audio_encoding: AudioEncoding

Audio encoding of the audio content to process.

sample_rate_hertz: i32

Sample rate (in Hertz) of the audio content sent in the query. Refer to Cloud Speech API documentation for more details.

language_code: String

The language of the supplied audio. Dialogflow does not do translations. See Language Support for a list of the currently supported language codes. Note that queries in the same session do not necessarily need to specify the same language. If not specified, the default language configured at ConversationProfile is used.

enable_word_info: bool

If true, Dialogflow returns SpeechWordInfo in StreamingRecognitionResult with information about the recognized speech words, e.g. start and end time offsets. If false or unspecified, Speech doesn’t return any word-level information.

use_timeout_based_endpointing: bool

Use timeout based endpointing, interpreting endpointer sensitivity as seconds of timeout value.

Implementations

impl SpeechToTextConfig

pub fn new() -> Self

pub fn set_speech_model_variant<T: Into<SpeechModelVariant>>(self, v: T) -> Self

Sets the value of speech_model_variant.

Example

use google_cloud_dialogflow_v2::model::SpeechModelVariant;
let x0 = SpeechToTextConfig::new().set_speech_model_variant(SpeechModelVariant::UseBestAvailable);
let x1 = SpeechToTextConfig::new().set_speech_model_variant(SpeechModelVariant::UseStandard);
let x2 = SpeechToTextConfig::new().set_speech_model_variant(SpeechModelVariant::UseEnhanced);

pub fn set_model<T: Into<String>>(self, v: T) -> Self

Sets the value of model.

Example

let x = SpeechToTextConfig::new().set_model("example");

pub fn set_phrase_sets<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of phrase_sets.

Example

let x = SpeechToTextConfig::new().set_phrase_sets(["a", "b", "c"]);

pub fn set_audio_encoding<T: Into<AudioEncoding>>(self, v: T) -> Self

Sets the value of audio_encoding.

Example

use google_cloud_dialogflow_v2::model::AudioEncoding;
let x0 = SpeechToTextConfig::new().set_audio_encoding(AudioEncoding::Linear16);
let x1 = SpeechToTextConfig::new().set_audio_encoding(AudioEncoding::Flac);
let x2 = SpeechToTextConfig::new().set_audio_encoding(AudioEncoding::Mulaw);

pub fn set_sample_rate_hertz<T: Into<i32>>(self, v: T) -> Self

Sets the value of sample_rate_hertz.

Example

let x = SpeechToTextConfig::new().set_sample_rate_hertz(42);

pub fn set_language_code<T: Into<String>>(self, v: T) -> Self

Sets the value of language_code.

Example

let x = SpeechToTextConfig::new().set_language_code("example");

pub fn set_enable_word_info<T: Into<bool>>(self, v: T) -> Self

Sets the value of enable_word_info.

Example

let x = SpeechToTextConfig::new().set_enable_word_info(true);

pub fn set_use_timeout_based_endpointing<T: Into<bool>>(self, v: T) -> Self

Sets the value of use_timeout_based_endpointing.

Example

let x = SpeechToTextConfig::new().set_use_timeout_based_endpointing(true);

Trait Implementations

impl Clone for SpeechToTextConfig

fn clone(&self) -> SpeechToTextConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SpeechToTextConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SpeechToTextConfig

fn default() -> SpeechToTextConfig

Returns the “default value” for a type.

impl Message for SpeechToTextConfig

fn typename() -> &'static str

The typename of this message.

impl PartialEq for SpeechToTextConfig

fn eq(&self, other: &SpeechToTextConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
