Cirrus Logic Launches Development Kit for Alexa Voice Services for Smart Speakers and Smart Home Applications
Cirrus Logic introduces a development kit for Alexa Voice Services (AVS) for smart speaker and smart home applications, including voice control devices, hands-free portable speakers and network speakers. The voice acquisition development kit for Amazon AVS uses Cirrus Logic's IC and software design to help manufacturers bring new Alexa products to market quickly, even in noisy environments and music playback, these new products enable high-accuracy wake-up triggers And command interpretation features. The low-power voice acquisition development kit for Amazon AVS includes a reference board with Cirrus Logic CS47L24 intelligent codec and CS7250B digital MEMS microphone, and a SoundClear algorithm for speech control, noise suppression, and echo cancellation. The complete voice acquisition reference design further enhances the implementation of the “Alexa†wake-up detection and audio capture functions under real-world conditions, enabling users to reliably interrupt high-pitched music or Alexa response playback even in moderately noisy environments. The intelligent codec uses an on-chip high-performance digital-to-analog converter (DAC) and a two-watt mono speaker driver for high-fidelity audio playback. Alexa Voice Services Director Priya Abani said: "We are pleased to be able to work with Cirrus Logic to help OEMs apply Alexa to more smart speakers and other audio devices. Cirrus Logic offers advanced capabilities for Amazon AVS's voice acquisition development kit. Acoustic tuning, along with proven hardware and software, enables device manufacturers to bring products to market faster and more efficiently." Carl Alberty, vice president of marketing for Cirrus Logic Audio Products, said: "With our experience in audio and voice ICs and software, we provide smart home application manufacturers with a powerful and easy-to-use voice acquisition development kit to help them develop support. Alexa's products. Our AVS development kit voice command performance is excellent, and when combined with Cirrus Logic tools and software, it helps OEMs bring Hi-Fi speaker products with superior Alexa voice interaction to market faster. †Cirrus Logic voice acquisition technology helps further improve performance Cirrus Logic's voice acquisition solution suppresses noise and other real-world interference, making voice interactions more accurate and reliable, giving users a better feel. This technology enhances the "Alexa" wake-up word detection in quiet and noisy environments, which can be achieved by users a few meters away from the device. Cirrus Logic's echo cancellation technology allows users to “plug in†or interrupt high-pitched music playback and Alexa response, which is the key to a great user experience, so Alexa can accurately respond to new command requirements. Cirrus Logic's MEMS microphones feature an ultra-low noise floor and a wide dynamic range (130 dB) to ensure accurate speech acquisition under harsh noise conditions, enabling Cirrus Logic's SoundClear algorithm to mask Alexa wake-up words and command accuracy Interference noise. Cirrus Logic's intelligent codecs integrate Hi-Fi DACs, stereo headphone amplifiers and mono speaker amplifiers to help OEMs reduce material costs from high-end speakers to simple digital assistant products. Designed with the need for ultra-low-power portable devices and accessories, the power consumption is typically 80% lower than competing solutions. The kit is a complete solution that includes a high-performance dual-microphone array, Raspberry Pi 3 (Rpi3), speakers, and a microSD card with all the required firmware pre-installed, which is a productivity boost . Cirrus Logic's console simplifies the operation of a wide range of RPi3 applications, providing a powerful, user-friendly interface for acoustic tuning and diagnostics. The schematic design and bill of materials for the Voice Acquisition Reference Board are designed for most AVS applications, and customers require only a few custom changes to further reduce time-to-market.
Function description
The socket is ordinary converter,with
two output 5V2A power USB power supply at the same time,can be very
convenient in use electrical appliances and recharge the equipment at
the same time,such as digital products like Iphone Ipad,MP3,MP4 etc.The
