HEAD acoustics Implements Alexa ACAR Testing

With HEAD acoustics’ comprehensive Alexa ACAR test implementation, we enable developers to leverage the full speech and communication potential of Alexa-built-in devices.

Amazon Alexa offers numerous services on Alexa-Built-In devices including ‘Alexa-to-Alexa calls’ to other users for qualified devices. This service is available for many products, including mobile and household devices and 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.

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

Therefore, Amazon has established the Alexa Communications Audio Requirements (ACAR, current version 2.1.3 June 2021) to optimize the user experience when performing an Alexa-to-Alexa call. They specify instrumental and auditory tests for various situations different types of devices must pass to qualify for Alexa-to-Alexa calls.

The HEAD acoustics ACAR implementation

A comprehensive test implementation for all device types as specified in Alexa ACAR is key to success for developers. The HEAD acoustics ACAR implementation and complementary HEAD acoustics test suites, e.g., ACQUA and labCORE with the software extension module coreIP-Alexa, which serves as a reference gateway for voice quality measurements of Alexa Built-In Devices, let them leverage the best-performing devices for all use cases and scenarios: With fast and convenient testing, comparison, and experimental optimization, ACAR ensures that devices implementing Alexa-to-Alexa calls meet all requirements laid out by Amazon and perform at their best; always, anywhere, and no matter the circumstances.
With the HEAD acoustics implementation of ACAR, our customers benefit from technology and experience that helps them provide consumers with the most relevant and enjoyable experiences.
