The demand for voice recognition services is on the rise. As Amazon's Alexa and Google's "Ok Google" become more advanced, users are expecting even higher accuracy and performance from voice-enabled devices. This growing need has pushed companies to develop more sophisticated solutions that can handle challenging audio environments.
Microsemi has introduced the AcuEdge Development Kit, designed specifically for Amazon AVS. This all-in-one development kit includes a development board that connects directly to a Raspberry Pi, along with a plastic frame that helps position microphones and speakers in various applications. It’s an ideal tool for developers looking to enhance speech recognition in smart home devices, industrial systems, and automated assistants.
To support the growing trend of human-machine interaction (H2M), the AcuEdge Development Kit is equipped with advanced audio processing capabilities. It enables better speech recognition in noisy or complex environments, which is crucial for IoT and Industrial IoT applications. The kit is currently available for Amazon AVS and offers a complete platform for testing and integration.
Shakin Sadeghi, Marketing Director at Microsemi, emphasized that the AcuEdge Development Kit allows third-party developers and OEMs to evaluate their H2M applications efficiently. It not only supports voice recognition but also helps speed up product development timelines. With this kit, businesses can quickly bring innovative voice-enabled products to market.
Another key feature of the AcuEdge Development Kit is its compatibility with Microsemi’s TImberwolf ZL38063 multi-microphone audio processor. This powerful DSP includes three sets of Synchronous Acoustic Echo Cancellers (AEC) and is field-programmable and upgradable. It also incorporates advanced algorithms such as Compressor/Limiter/Expander (CLE), beamforming, and both fixed and non-stationary noise suppression, significantly improving voice clarity and distance performance.
According to Sadeghi, the TImberwolf system can capture clear voice input even from four to five meters away, making it suitable for use in noisy environments like offices, factories, or homes. This makes it a reliable solution for voice-activated devices in real-world settings.
The AcuEdge Development Kit comes with a TImberwolf evaluation board, a Raspberry Pi connector, and a speaker stand for quick setup and testing. While the Raspberry Pi runs the Amazon AVS client and processes the wake-up word for Alexa, the TImberwolf processor handles multiple audio enhancements, dramatically boosting speech recognition accuracy.
Whether you're developing smart home devices, industrial automation systems, or any IoT-based application, the AcuEdge Development Kit provides a powerful and flexible platform to explore the future of voice technology.
