public sealed class SpeechTranscription : IMessage<SpeechTranscription>, IEquatable<SpeechTranscription>, IDeepCloneable<SpeechTranscription>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Video Intelligence v1 API class SpeechTranscription.
A speech recognition result corresponding to a portion of the audio.
public RepeatedField<SpeechRecognitionAlternative> Alternatives { get; }
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.
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.
