Audio AI
Speech enhancement and emergency vehicle detection for responsive voice assistance and situational awareness.
Our Audio AI portfolio provides you with a set of advanced, flexible and scalable speech enhancement and signal processing solutions tailored for modern voice assistants, voice communication applications and acoustic event detection. By leveraging our pioneering deep learning technologies, our solutions ensure smooth and seamless experiences across a wide range of use cases.
Together, these technologies bring intelligence and awareness to in-vehicle audio – enhancing communication through advanced speech processing and boosting safety with real-time siren detection.
Speech Signal Enhancement (SSE)
Deployed in more than 350 million vehicles and across kiosks, robots, and industrial settings worldwide, SSE uses advanced algorithms to suppress ambient noise, eliminate unwanted sounds, and reduce speech interference—enhancing the quality of voice-powered experiences.
User Benefits
Crystal-clear Phone Calls: In hands-free mode, echoes and disturbing background noise are effectively filtered out ensuring drivers and passengers are heard clearly on the phone while on the road.
Natural Voice Assistant Conversation: Barge-in capabilities enable drivers and passengers to jump in mid-response, making engagements with their in-car assistants more fluid and efficient.
Personalized In-Cabin Experiences: Intelligent and efficient multi-zone processing supports varying audio needs of drivers and passengers. For instance, while some passengers engage in a hands-free call, others can enjoy music or interact with the voice assistant without interfering with one another.
OEM Benefits
Enhanced User Experience and Efficiency: By combining advanced speech signal enhancement techniques with state-of-the-art AI models, our solution delivers exceptional performance while maintaining moderate CPU usage – ideal for embedded platforms.
Seamless Integration: Integration into all major audio frameworks and across all major CPUs and DSPs regardless of hardware or operating systems allows for quick and easy deployment.
Scalability & Use-Case Flexibility: The same SSE integration can support a wide variety of use cases and microphone configurations – from basic hands-free calling to advanced multi-zone voice assistants with complex, distributed microphone arrangements.
Comprehensive Global Customer Support: Our experienced expert team guides you through every stage of your project – from system design and integration support, to qualification and certification of your application in accordance with current ITU-T and third-party standards (e.g., CarPlay), either at one of our car labs in Germany, the USA, India and China, or directly at your premises.
In-Car Communication (ICC)
ICC ensures effortless in-car communication, allowing passengers to speak naturally without raising their voices or turning around. By transmitting speech between front and rear seats, ICC enhances conversations and delivers high-quality audio through advanced signal processing that filters out noise, echoes, and distortions—making interactions clearer and more comfortable.
User Benefits
Seamless Conversations: Allows natural communication between front and rear passengers without shouting, improving in-car interactions.
Enhanced Audio Quality: Eliminates noise, suppresses wind buffets, and ensures clear speech transmission through optimized signal processing.
More Enjoyable Rides: Audio Boost transforms the car into a karaoke stage, enhancing vocals with audio effects for fun group trips.
OEM Benefits
Flexible Integration: Works with standard in-car microphones and advanced setups for tailored deployments.
Distinctive Feature Addition: Offers a premium communication experience that differentiates brands in the market.
Efficient Implementation: Easily enabled through software configuration without requiring hardware changes, making adoption simple and cost-effective
Emergency Vehicle Detection (EVD)
With coverage across 47 countries and over 1,500 different sirens, EVD helps detect sirens and proactively alerts drivers, so they can move aside and make way for emergency vehicles—enhancing safety for both automated and human-driven cars.
User Benefits
Increased Situational Awareness: Helps drivers stay alert to approaching emergency vehicles even when they may be distracted or unaware of their surroundings.
Faster Reaction Time: Ensures drivers receive clear alerts by filtering out in-car entertainment and speech, enabling quicker, more informed decisions on the road.
Enhanced Safety: Determines the direction of emergency vehicles when paired with exterior microphones, helping drivers navigate safely and avoid potential collisions.
OEM Benefits
Regulatory Compliance: Helps meet requirements in countries where it is mandated to provide the right of way for emergency vehicles.
Flexible Deployment: Works with various microphone types for interior or exterior integration.
Global Support: Covers 45+ sirens worldwide and is continuously updated and expanded.
