Microphone Array ASR-assist Audio Processor
From wearables to smart lighting, voice control is increasingly becoming consumers’ preferred way to interact with electronics. As developers build products of various sizes and designs to meet consumer demand, they often have trouble scaling to meet different Bill of Materials (BOM) and form factor requirements in end applications. Microchip announced that its AcuEdge™ ZLK38AVS Development Kit for Amazon Alexa Voice Service (AVS) now introduces far-field voice pick up and the flexibility to build devices with multiple mic array configurations. The solution reduces BOM costs while addressing the requirements of small-form-factor designs.
Designed for world-class voice front-end audio applications, Microsemi’s new ZL38063 audio processor features the company’s AcuEdge™ technology. This innovative technology is a set of highly-complex and integrated algorithms that significantly improves automatic speech recognition (ASR) for both embedded and cloud-based ASR solutions. The ZL38063 delivers audio enhancements that perform noise reduction and smart automatic gain control (AGC), enabling speech recognition at distance in noisy, real-world conditions.
