Seminars in China: Smart Speakers and Automotive Audio

The Challenges of Testing Speech Controlled Audio Systems

Your devices got smarter. Did your test system?

Learn how to implement open loop tests for both playback and recording in a range of devices including smart speakers, automotive audio, robots, IoT devices and more in this practical seminar.

Open loop testing (testing devices where inputs and outputs are independent) enables many types of smart devices and their components to be tested in various formats and situations including:

  • Smart speakers, smart watches and other smart devices
  • Microphone arrays
  • Speech recognition systems with microphones
  • In-vehicle audio systems
  • Audio devices/systems with no physical inputs or outputs
  • Testing in noisy environments

We explain how to measure the same parameters as traditional loudspeakers, discussing such challenges as injecting and extracting response signals, time delays, and triggering the system using voice commands. We also demonstrate how to measure microphone array performance, speakerphone performance and more. Course content includes:

  • Stimulating and capturing responses from a device where you don’t have direct access to the microphone or speaker (open loop testing).
  • Delays, asynchronous stimulus / acquisition, and working with the ‘cloud’
  • Testing with real world signals such as speech and music, and how to analyze results from these test stimuli
  • Voice Recognition – key word spotting, wake word testing, directionality, and the effect of background noise on voice recognition performance
  • Telephony – testing smart speakers for hands-free calling

Speakers /主讲人: Steve Temme, Listen, Inc. and Peter Wulf Andersen, GRAS.

Date & Locations /时间与地点:

2019年1月15日(Tuesday) – Taipei台北
2019年1月16日(Wednesday) – Shenzhen深圳

ISEAT- Shenzhen, China – Nov 4-5, 2017

iseat_logoWe will be exhibiting at ISEAT in Shenzhen on Nov 4-5, 2107. On display will be our SoundCheck audio test system and associated hardware for testing a range of audio devices including speakers, microspeakers, headphones, microphones, smartphones, tablets and more.

Listen president, Steve Temme, will also be presenting a technical paper written with Viktor Dobos of Harman Automotive on production line loudspeaker measurements. In this paper, he addresses the different measurements that can be made at the end of a production line, and which ones offer comprehensive product QC while maintaining high speed and throughput.
