Constructors

StreamingRecognitionResult({Iterable<SpeechRecognitionAlternative>? alternatives, bool? isFinal, double? stability, Duration? resultEndTime, int? channelTag, String? languageCode})

factory

Properties

alternatives → List<SpeechRecognitionAlternative>
May contain one or more recognition hypotheses (up to the maximum specified in max_alternatives). These alternatives are ordered in terms of accuracy, with the top (first) alternative being the most probable, as ranked by the recognizer.
no setter
channelTag ↔ int
For multi-channel audio, this is the channel number corresponding to the recognized result for the audio from that channel. For audio_channel_count = N, its output values can range from '1' to 'N'.
getter/setter pair
eventPlugin → EventPlugin?
Subclasses can override this getter to be notified of changes to protobuf fields.
no setterinherited
hashCode → int
Calculates a hash code based on the contents of the protobuf.
no setterinherited
info_ → BuilderInfo
no setteroverride
isFinal ↔ bool
If false, this StreamingRecognitionResult represents an interim result that may change. If true, this is the final time the speech service will return this particular StreamingRecognitionResult, the recognizer will not return any further hypotheses for this portion of the transcript and corresponding audio.
getter/setter pair
isFrozen → bool
Returns true if this message is marked read-only. Otherwise false.
no setterinherited
languageCode ↔ String
Output only. The BCP-47 language tag of the language in this result. This language code was detected to have the most likelihood of being spoken in the audio.
getter/setter pair
resultEndTime ↔ Duration
Time offset of the end of this result relative to the beginning of the audio.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stability ↔ double
An estimate of the likelihood that the recognizer will not change its guess about this interim result. Values range from 0.0 (completely unstable) to 1.0 (completely stable). This field is only provided for interim results (is_final=false). The default of 0.0 is a sentinel value indicating stability was not set.
getter/setter pair
unknownFields → UnknownFieldSet
no setterinherited
