encodedInputTranscript

The text used to process the request.

If the input was an audio stream, the encodedInputTranscript field contains the text extracted from the audio stream. This is the text that is actually processed to recognize intents and slot values. You can use this information to determine if Amazon Lex is correctly processing the audio that you send.

The encodedInputTranscript field is base-64 encoded. You must decode the field before you can use the value.
