Response APIs for Custom Skills 

Response APIs for custom skills enable you to respond to requests in a custom way, with speech, audio, visuals, and links.

Speech

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.

Audio

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.

APL for Audio (Beta)

You can use APL for audio to mix speech, sound effects, music, and other audio at runtime. 

Visuals

Alexa Presentation Language

Create visually rich Alexa skills for devices with screens and adapt them for different device types such as the Echo Show, Echo Spot, and Fire TV.

Alexa Web API for Games

Build for multimodal devices using HTML5 and web technologies like Canvas 2D, WebAudio, WebGL, JavaScript, and CSS.

Links

Alexa for Apps

You can enable customers to quickly get to key content and functionality in your app, just by asking Alexa.
