The Audio of Things, Part 3: The Future is Now
January 19, 2020
In this third and final part of the AoT blog series, we’ll take a look at some of the recent innovations that are finally bringing voice-based human/machine interfaces (HMIs) to the majority of consumer products.
While there’s been continual improvement in cloud-based technologies like automatic speech recognition (ASR) and natural language understanding (NLU), it’s largely been “edge-based” innovations that have knocked down the final barriers to the spread of voice-based HMIs.
The Audio of Things, Part 2: What's the hold up?
January 4, 2020
This is the second of a three-part series that explores the role of audio in our evolving relationship with machines.
What do flying cars and sound-based HMI's have in common?
They're both super convenient, they're both challenged by the laws of physics, and growing up, I definitely thought they'd both be everywhere by now! OK, so gravity is tough to beat, but what gives with voice interfaces? Why are we just now starting to see the spread of Machine Hearing?

DSP Concepts Audio Weaver® Featured in New Porsche Video
March 4, 2019
DSP Concepts Audio Weaver Automotive technology is prominently featured in a new YouCar video that details the development process for the 2020 Porsche 911 type 992. The audio development section of the video shows Porsche's audio engineers using Audio Weaver to configure the Burmester audio systems being developed for the car, including as many as 21 drivers in a single system. It also demonstrates Audio Weaver's Automotive Measuring Suite, as Porsche engineers use the software to measure the performance of the system from inside the car.
DSP Group adds DSP Concepts TalkTo™ Voice Front End to new line of floating-point DSP chips
February 26, 2019
San Jose and Santa Clara, CA – February 25, 2019 – DSP Group, Inc., a global leader in wireless chipsets for a wide range of smart-enabled devices, and DSP Concepts, Inc., a developer of embedded audio processing solutions, have announced that DSP Group’s DBMD7 line of floating-point audio processing chips will incorporate TalkTo™, DSP Concepts’ new audio front end technology for voice-controlled systems.
Blog: AIC lets Far-Field Voice UI work in places where others can’t
June 25, 2018
With the rise in popularity of voice UI systems has come a rise in reports of system error. Reports of a smartspeaker accidentally making a phone call or sending an e-mail appear in the media often, putting pressure on manufacturers to make these systems better at distinguishing actual commands from false triggers.
Blog: How to speed up development of car audio systems
March 29, 2018
Comparing today’s car audio systems to those of 10 years ago is like comparing an iPad to a 1980s TV: They perform some of the same functions, but the modern product is vastly more capable and complex. Not only does a modern car audio system play radio, it must accommodate multiple sources (Bluetooth, USB sticks, analog inputs and CDs), and separate the driver’s voice from road and engine noise for phone calls and voice commands. It may have to generate warning sounds for pedestrians, and synthesize engine sounds to enhance the driving experience.
Blog: The Challenges of Engineering Audio for Self-Driving Cars
February 28, 2018
Most of the recent talk in the automotive industry – and in the tech world, urban planning and the energy industry, too – has been about the impact that future self-driving cars will have on the way we live and get around town. But while there’s been plenty of debate about how safe these cars will be, and how soon they’ll come to market, there’s been little discussion of what these cars will be like on the inside – or how their entertainment and telecommunications systems may differ compared with the systems in today’s cars.
Can Advanced Audio Processing Be Done on an SoC?
January 1, 2018
The automotive industry is starting to move in a direction that the computer and mobile technology industries did more than a decade ago: performing audio processing on a system microprocessor rather than on a dedicated DSP. By eliminating the dedicated DSP and the microprocessor, flash and RAM chips that support it, and moving these functions onto a system-on-a-chip (SoC), a savings of about $10 to $15 per vehicle can typically be realized.
The Challenge of the Always-Listening Car
November 27, 2017
Automotive voice command systems are about to go through a radical change, because the success of smartspeakers such as the Amazon Echo and Google Home has elevated consumer expectations. When the speakers people use at home work entirely from voice command, using natural language, why do drivers still have to push a button to issue a voice command inside their cars, and memorize specific commands that the car can understand?
