--request-content-type <string> | Indicates the format for audio input or that the content is text. The header must start with one of the following prefixes: PCM format, audio data must be in little-endian byte order. audio/l16; rate=16000; channels=1 audio/x-l16; sample-rate=16000; channel-count=1 audio/lpcm; sample-rate=8000; sample-size-bits=16; channel-count=1; is-big-endian=false Opus format audio/x-cbr-opus-with-preamble;preamble-size=0;bit-rate=256000;frame-size-milliseconds=4 Text format text/plain; charset=utf-8 |
--response-content-type <string> | The message that Amazon Lex returns in the response can be either text or speech based on the responseContentType value. If the value is text/plain;charset=utf-8, Amazon Lex returns text in the response. If the value begins with audio/, Amazon Lex returns speech in the response. Amazon Lex uses Amazon Polly to generate the speech using the configuration that you specified in the requestContentType parameter. For example, if you specify audio/mpeg as the value, Amazon Lex returns speech in the MPEG format. If the value is audio/pcm, the speech returned is audio/pcm at 16 KHz in 16-bit, little-endian format. The following are the accepted values: audio/mpeg audio/ogg audio/pcm (16 KHz) audio/* (defaults to mpeg) text/plain; charset=utf-8 |
--input-stream <blob> | User input in PCM or Opus audio format or text format as described in the requestContentType parameter |
