Response APIs for Custom Skills 

Response APIs for custom skills enable you to respond to requests in a custom way, with both voice and visuals.

Voice

Text-to-Speech

After Alexa sends a request to your skill, you can respond with a JSON structure that tells Alexa what to do. With it, you can send a string of text that Alexa will convert to speech and respond to your customers using text-to-speech (TTS).

SSML

You can use Speech Synthesis Markup Language (SSML)  to add pauses, emotion, and other effects to your output speech.

Amazon Polly

You can use the default Alexa voice with your output speech or choose from more than 20 male and female voices with Amazon Polly to make your skill more engaging.

Pre-Recorded Audio

You can add pre-recorded audio to your Alexa skill by using audio from the ASK Sound Library or by providing your own audio through AudioPlayer.
