True-to-reality tests of smart speaker & voice-operated smart home devices | Application Webinar

The use of speech-controlled smart home devices is increasing rapidly – with smart speakers at the core of the movement. Besides the speech recognition and audio performance, manufacturers should test the communication quality of these devices in order to ensure the finest user-experience. HQS-SmartHome is the new ACQUA test suite for fully automated tests of the communication quality of voice-operated smart home devices. The test sequences consider acoustic room properties, multiple moving talkers, directivity and many more critical aspects. HQS-SmartHome enables realistic and reproducible measurements. Thus, it ensures optimal product quality from the development phase through to end-of-line testing. This webinar will offer in-depth information on comprehensive tests of voice-operated smart home devices. Topics: A look at conversational tests like… • Perceptual echo assessment • Spectral echo attenuation • Double talk performance in sending direction Single talker tests like… • Delay variation / clock drift • Muted microphone behavior • Speech quality in receiving with impairments Multi talker tests like… • Near-end switching characteristics • Speech quality with concurrent talkers Background noise and room reverberation Link to Website: https://www.head-acoustics.com Link to LinkedIn: https://www.linkedin.com/company/head-acoustics-gmbh Link to Twitter: https://www.twitter.com/HEADacoustics
