    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.
