Overview

Package transcribestreaming provides the API client, operations, and parameter types for Amazon Transcribe Streaming Service.

Amazon Transcribe streaming offers three main types of real-time transcription: Standard, Medical, and Call Analytics.

  • Standard transcriptions are the most common option. Refer to for details.
  • Medical transcriptions are tailored to medical professionals and incorporate medical terms. A common use case for this service is transcribing doctor-patient dialogue in real time, so doctors can focus on their patient instead of taking notes. Refer to for details.
  • Call Analytics transcriptions are designed for use with call center audio on two different channels; if you're looking for insight into customer service calls, use this option. Refer to for details.

StartStreamTranscriptionEventStream provides the event stream handling for the StartStreamTranscription operation.

For testing and mocking the event stream this type should be initialized via the NewStartStreamTranscriptionEventStream constructor function. Using the functional options to pass in nested mock behavior.

func NewStartStreamTranscriptionEventStream 

func NewStartStreamTranscriptionEventStream(optFns ...func(*StartStreamTranscriptionEventStream)) *StartStreamTranscriptionEventStream

NewStartStreamTranscriptionEventStream initializes an StartStreamTranscriptionEventStream. This function should only be used for testing and mocking the StartStreamTranscriptionEventStream stream within your application.

The Writer member must be set before writing events to the stream.

The Reader member must be set before reading events from the stream.

func (*StartStreamTranscriptionEventStream) Close 

func (es *StartStreamTranscriptionEventStream) Close() error

Close closes the stream. This will also cause the stream to be closed. Close must be called when done using the stream API. Not calling Close may result in resource leaks.

Will close the underlying EventStream writer and reader, and no more events can be sent or received.

func (*StartStreamTranscriptionEventStream) Err 

func (es *StartStreamTranscriptionEventStream) Err() error

Err returns any error that occurred while reading or writing EventStream Events from the service API's response. Returns nil if there were no errors.

func (*StartStreamTranscriptionEventStream) Events 

func (es *StartStreamTranscriptionEventStream) Events() <-chan types.TranscriptResultStream

Events returns a channel to read events from.

func (*StartStreamTranscriptionEventStream) Send 

func (es *StartStreamTranscriptionEventStream) Send(ctx context.Context, event types.AudioStream) error

Send writes the event to the stream blocking until the event is written. Returns an error if the event was not written.
