Machine Learning
for Sound in Automotive:

Automotive OEMs and ODMs are redefining the innovation for the driver safety and self driving cars, AMI Technologies offering the Audio and Noise Reduction algorithms to accelerate the innovation. AMI Technologies mastered the next big sensor MEMS microphone in Automotive and Machine Learning for the Sound Processing. Noise Reduction algorithms like Acoustic Echo Cancellation, Beam Former, Wind Noise Reduction and Stationary Noise Reduction algorithms for engine and AC will improve the Automatic Speech Recognition (ASR). Speaker Localization or Direction of Arrival (DOA) will further render the data meaningfully. AMI Technologies offers the single stop solution for the Audio, Speech and Noise processing needs of the Automotive OEMs and ODMs.


Our Automotive Reference design for Machine Learning for Sound processing and Audio processing will offer very flexible design and tuning on the final product, it reduces the 80% development cost and time. It includes the below Speech Processing Modules to improve the Automatic Speech Recognition (ASR)
