12.30: Light lunch

13.15-16.00: Voice-Activated Device Testing, Automotive, smart speakers, hearables

  • Automotive infotainment systems, hearables, smart speakers and many other audio devices are now voice-activated. Such devices are complex to test as they have numerous wired and wireless connections and often contain signal processing, both on the record and the playback side. This means that their characteristics change according to ‘real world’ conditions of the environment that they are used in, such as automotive cabin and roaad noise, background noise, playback levels, and room acoustics. Furthermore, many aspects of the device may need to be tested, ranging from voice recognition to music playback, operation as a hands-free telephone, and even hearing assistance. Often measurements need to be made at different levels and different environmental conditions. In this session, we will discuss the test configurations, tools and techniques that enable accurate measurement of the audio performance of such devices under the many various real-world conditions in which they are used.

16.00-17.00: Hands on and drinks

AES Convention– New York – October 16-19, 2019

Although Listen won’t be exhibiting, president Steve Temme will be at the event and will be participating in two product development sessions detailed below.

 

Product Development: PD09 – Does Automotive Audio Need a Systems Approach?

Thursday, October 17, 1:30 pm — 3:00 pm (1E09)

Chair: Roger Shively, JJR Acoustics, LLC

Panelists: John Busenitz, Bose Corporation, Pietro Massini, Ask Industries S.p.A, Greg Sikora, Harman International, Steve Temme, Listen, Inc.

Some component specifications do not translate to good system performance. A good example is resonance frequency. This often does not correspond well to performance characteristics in the automotive environment. Some potential improvements would be low-frequency SPL, or a parameter combination such as Fs/Qts or EBP (Fs/Qes). The system performance goals should drive the transducer component specification. Hence, this workshop will host leading industry experts in automotive audio and test/measurement solutions to discuss pros and cons of component vs. system specifications.

 

Product Development: PD10 – Diagnostics for Production Vehicle Audio Systems

Thursday, October 17, 3:15 pm — 4:30 pm (1E09)

Presenters: Jonathan Gerbet, Klippel GmbH, Steven Hutt, Equity Sound Investments, Steve Temme, Listen, Inc.

Audio systems in production vehicles are known to exhibit vehicle to vehicle performance variance [1]. The root causes of variance can include loudspeaker driver manufacturing tolerance, mounting issues such as missing or misaligned gaskets, or wrong loudspeaker drivers mounted in the system. A diagnostics method to compare actual production vehicle audio systems is defined along with a method for correction and calibration of production vehicle audio systems. The diagnostics procedure may be implemented at production end-of-line, at vehicle distribution center or at a dealer service center in the field after delivery to a customer.

ISEAT- Shenzhen, China – Nov 9-10, 2019

We will be participating in China’s leading electroacoustics event, ISEAT on November 9-10 with our exclusive China distributor, S&V Samford.

Steve Temme will be presenting a paper on ‘The Challenges of Testing Voice Controlled Audio Systems’. In this paper, he highlights the common factors in testing smart speakers, hearables, and automotive infotainment systems, such as open loop testing, measuring speech recognition, and testing in the presence of background noise, and explains how to correctly measure such devices.

On display will be our SoundCheck audio test system and associated hardware for testing a range of audio devices including smart speakers, headphones & smart hearables, automotive audio, microspeakers, microphones, smartphones, tablets and more.

 

Paper Abstract:

Smart devices that are voice-controlled such as smart speakers, hearables vehicle infotainment systems are notoriously complex to test. They have numerous connections from wired to wireless and contain much signal processing, both on the record and on the playback side. This means that their characteristics change according to ‘real world’ conditions of the environment that they are used in, such as background noise, playback levels, and room acoustics. Furthermore, their multifunctional nature means that there are many aspects of the device that may need to be tested, ranging from voice recognition to music playback and operation as a hands-free telephone, and in the case of hearables, hearing assistance. Due to their complex non-linear use cases, these devices often need to be tested at different levels and different environmental conditions. This paper focuses on tools and techniques to accurately measure the audio performance of such devices under the many various real-world conditions they are used in.

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.
