Voice interface
Go for Infineon quality and discover leading-edge audio?input for voice-user-interfaces (VUI)
XENSIV? MEMS microphones represent a new benchmark in performance, and current audio chain limitations can be overcome. A product needs reliable sensitive microphones that suit the system. For a voice system to work well, good raw data from the microphone must be fed to the voice processing algorithms running on the main system. Infineon helps you to integrate fast and easy into your design so that you will get your product to market quickly. Testing schemes can be fulfilled without any delays.
If you want to integrate a voice-controlled user interface (VUI) into a product that previously lacked an audio interface or implement an appliance design e.g. in smart speakers, TVs, and home appliances, you know it is not without roadblocks.
Infineon helps you at the start of your concept and during your development process to engineer a successful digital audio assistant design with devices such as XENSIV? MEMS microphones.
Voice user interfaces need to be designed right from the beginning: it is critical for both consumer acceptance and integration of value-added services down the road. Interaction between a human and a digital assistant must become as intuitive and natural as possible.
Design products and devices that provide users with a best-in-class voice experience. For example the IM69D130 MEMS mic, ideal for applications that require low self-noise (high SNR) and distortion, a wide dynamic range, plus a high acoustic overload point.
Discover exceptional system benefits
Depending on the precise use case, highly sensitive Infineon MEMS microphones provide a range of system benefits.
- Whisper mode: Even softly spoken or whispered voice commands are picked up in more cases in systems with the Infineon mic. This improves user convenience and maximizes interaction.
- Multi-room and distance scenarios: As users become more at ease with voice technology, they expect more of their devices and seek natural interaction from across the room or in a different room.
- Regular voice: For devices with voice control to add significant convenience to everyday life, the technology must live up to its promise. Infineon mics lay a solid foundation for a great voice user experience.
Save space and costs with Infineon design solution
Once the voice is used, the design of products is affected too, as buttons on consumer products are reduced or even eliminated.
Our solutions also allow you to reduce the number of microphones in certain applications, saving BOM and space, and reducing the overall system cost.
Reference designs
In order to speed up the time to market and facilitate easy integration, reference designs with an application or audio processors or digital signal processors are crucial. Many manufacturers, such as suppliers of smart home products, already greatly benefit from audio design support.
Discover complete modules that can be integrated into your solution in a convenient way.
Premium MEMS microphones and cutting-edge audio processing are the key elements for making voice-controlled devices truly ready for everyday situations. Features like turning off a TV across different rooms as well as the ability to whisper to Alexa to dim down the light will be key differentiators of next-generation voice-user interfaces. That is why Infineon and its voice-user interface ecosystem partners are leveraging their technological expertise to provide innovative reference platforms and ready-to-use next-generation voice-user interface solutions.
