ACAR – Amazon Alexa Communications Audio Requirements

Amazon Alexa offers numerous services on Alexa-Built-In devices including ‘Alexa-to-Alexa calls’ for qualified devices to other users. This service is available for a variety of products, including mobile and household devices as well as cars. These products and devices work in individual acoustic situations, making it challenging for their manufacturers to meet Amazon’s requirements and ensure optimal performance.

With our implementation of ACAR, our customers benefit from technology and experience that helps them provide consumers with the most relevant and enjoyable experiences

The advantage: Alexa technology in your device

Integrating Alexa communication service into products and measuring their audio quality in Alexa-to-Alexa calls is an important selling point that gives customers real added value.

Speeding up the development process

Additionally, using Alexa reduces the cost and effort of building the core capabilities of an intelligent assistant, so companies can focus time and resources on creating unique features that inspire their customers.

The goal: Seamless communication at any time, any place – and no matter the circumstances

Alexa Communications Audio Requirements’ (ACAR current version 2.1.3 June 2021) was established to optimize the user experience when performing an Alexa-to-Alexa call. This document specifies instrumental and auditory tests for various situations different types of devices must pass to qualify for Alexa-to-Alexa calls.
