TDK Provides MEMS Microphone Solutions for Expanding the Possibilities of Interactive Robots
Interactive robots using robotics and AI technologies such as smart speakers are being developed one after another. For voice recognition, which is a key technology for these interactive robots, multiple sophisticated and compact microphones are required to recognize the speaker’s voice against the background noise. TDK provides various ultra-compact MEMS microphones using advanced semiconductor microfabrication techniques, supporting the advancement of voice recognition technology and further improvement of the intelligence of interactive robots.
Technical Issues of Voice Recognition for Interactive Robots
Robots that perform operations instead of humans or support operations by humans are largely categorized into industrial robots and business/service robots. Business/service robots have been growing quickly recently, and it is expected that their world market size will reach 52 billion USD by 2025 (Source: “Reality and Future Outlook of Worldwide Robot Related Market 2018” by Fuji Keizai Co., Ltd.). Among business/service robots, the growth of interactive robots, in particular, is expected.
Interactive robots automatically interact with humans using AI. They can actuate movements, and/or speech in accordance with the interaction, and are expected to play a role in solving global social issues, such as aging societies and labor shortages.
The World Market Size for Business/Service Robots
Created based on “Reality and Future Outlook of Worldwide Robot Related Market 2018” by Fuji Keizai Co., Ltd.
The user interface for interactive robots is provided by voice recognition technology. Interaction robots need to detect the direction of the speaker even if he/she speaks from a distance and recognize his/her speech against background noise. As a solution, multiple microphones are installed to find the direction of the speaker from the differences between the times of arrival and the strengths of the voice received at the respective microphones. This technology is called beamforming. It is also required to remove noise components only from background noises coming from various directions with noise cancelling technology2 using multiple microphones.
To accomplish beamforming and noise cancelling, it is necessary to use multiple microphones that are compact and light as possible. On the other hand, to accurately recognize the speaker’s voice, a high S/N ratio3 is required. In general, however, the higher the S/N ratio is, the larger the dynamic range4 becomes. Microphones for interactive robots face the challenge of maintaining a high S/N ratio and suppressing distortion at the same time as being compact and light.
Voice Recognition Technology Solutions Using Compact MEMS microphones
TDK’s various MEMS microphones solve the problems of beamforming and noise canceling. The ICS-40730, which TDK provides under the InvenSense brand, is a compact and high-performance MEMS microphone. 4.72 x 3.76 x 3.50 mm in size, it features a high S/N ratio of 74 dBA and is suitable for a microphone array5 for beamforming. Even at a sound level of 105 dB, the ICS-40730 can suppress the distortion at a maximum of 0.6% to maintain a high S/N ratio. (The sound level that is considered noisy is 110 dB, such as the level of the noise under an elevated railway track when a train is passing.) It also significantly contributes to a noise-canceling function.
Example of beamforming using MEMS microphone array
The use of an array of compact microphones with a high S/N ratio enables beamforming technology that can separate a specific sound source and emphasize a specific sound among multiple sound sources.
In addition to the ICS-40730, TDK provides a lineup of MEMS microphones for various applications. TDK’s microphones are used for smartphones, notebook computers, tablets, wearable devices, and hearing aids as well as voice recognition interfaces incorporated in interactive robots and luxury cars. These microphones include MEMS components, which are acoustic sensors using MEMS technology—TDK’s core technology—and ASICs (Application Specific Integrated Circuit) in a single package.
MEMS microphones for robotic vehicles
The above picture shows a vehicle equipped with a voice recognition interface using MEMS microphones. Now we have entered the era of interaction with robotic vehicles, and voice recognition is expected to be a key technology in autonomous driving.
Robots have evolved to be more human-like. Humanoid robots are equipped with a lot of sensors to control the joints and the posture so that human-like movements can be achieved. In addition to MEMS microphones and various other MEMS sensors, TDK provides a variety of sensors such as angle/position sensors using semiconductor technology, thin film technology, magnetic technology, and temperature/pressure sensors using electronic ceramics technology, together with advanced software to support the development of robotics.

MEMS microphone “ICS-40730”
The ICS-40730 is a bottom-ported MEMS microphone with ultra-low noise and differential analog output. The ICS-40730’s 74 dB SNR and ±2 dB sensitivity tolerance make it an excellent choice for microphone arrays and voice command applications.
