responseContentType

var responseContentType: String?

The message that Amazon Lex V2 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 V2 returns text in the response.

  • If the value begins with audio/, Amazon Lex V2 returns speech in the response. Amazon Lex V2 uses Amazon Polly to generate the speech using the configuration that you specified in the responseContentType parameter. For example, if you specify audio/mpeg as the value, Amazon Lex V2 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
