To learn more about NLU, see What Is Natural Language Understanding? NLU converts that text into intents for Alexa to act on.To learn more about ASR, see What Is Automatic Speech Recognition?. ASR converts customer speech into text.Use this table to help with your audio hardware and processing choices during your design process.Ībout Automatic Speech Recognition (ASR) and Natural Language Understanding (NLU) profilesĪlexa uses a combination of Automatic Speech Recognition (ASR) and Natural Language Understanding (NLU) to understand user speech and respond with precision. The following table presents some common device form factors and the interaction types available. Touch-initiated devices require a user to either tap or hold a physical control, such as a button, to talk to Alexa.įor more details about expected user interactions, see the UX design guidelines.Voice-initiated devices allow users to invoke the "Alexa" wake word to start an interaction.Should your device have direct audio output? Do you expect your device to be physically located near the user or farther away? Do you expect users to wear the device or hold the device in their hands?Ī device can interact with Alexa either by user voice or by touch: One factor in designing audio solutions for your device is determining how you expect users to interact with Alexa. To help you with your Alexa Voice Service (AVS) implementation, see Amazon Developer Services Agreement and AVS Functional Requirements for guidance. When Alexa understands user utterances and returns appropriate responses, these interactions contribute to a positive user experience with your device with your device.Īs you design your product, consider the hardware-related options related to the audio interactions for your device. One aspect of the user experience with an Alexa Built-in device is the quality of audio interactions between the device and Alexa.
