NXP's MCU-based local voice control solution leverages the i.MX RT106L crossover MCU to enable developers to quickly and easily add local voice commands to their products. This ultra-small form factor, production-grade hardware design runs on FreeRTOS with fully integrated software for rapid out-of-the-box evaluation and proof-of-concept development. This turnkey solution minimizes time to market, reduces risk and reduces development effort, allowing OEMs to easily add functionality to their smart home and smart appliance products without requiring Wi-Fi and cloud connectivity. The voice function solves many consumers' concerns about privacy.

2017年CES (国际消费电子展)已落下帷幕,通过此次展会可以看出,科技巨头们纷纷对智能语音助手与智能家居进行了布局,把语音控制作为未来智能家居的重要入口,并加强了相关生态链的建设,但是BLE作为IOT无线连接的最广泛接入方式,并没有将语音传送纳入其标准协议。那么有没有什么方案可以将BLE和语音传送有效结合在一起呢?答案是肯定的,ST BlueVoice 就是一种基于BLE来传送语音信号的完美
; DSP系列产品,这些产品都具备语音处理的能力。两种系列的产品各有千秋,分别适用于不同的应用。 在选择DSP和ARM这两种解决方案时,考虑的关键因素在于这款设备能否或将如何利用云语音平台。当中有三种应用场景:第一种是离线,所有的处理过程都在本地设备上发生。第二种是在线,通过基于云端的语音处理设备,如亚马逊的Alexa,谷歌助手或IBM
对纹波抑制效果很好。 221、请问可以用在照明上么 可以啊,用来开关灯及调灯色 222、请问ASR的主要优势有哪些? 我们支持嵌入式ASR,触发和命令词检测无需联网的本地语音控制 223、本地语音识别语音库是可以自己扩展的么? 百度好像是可以的,其他家需要确认。 224、音频处理时功耗多少? 150mw左右。 225、请问工作温度范围多少?谢谢 工业级(−40 °
对开发板的默认固件进行了使用说明,这是一个简单的语音控制程序,能够控制灯的亮灭和颜色。 要开发ESP32-Korvo语音功能程序,需要安装ESP-IDF和ESP-Skainet。其中ESP-IDF是开发ESP32的基本工具,而ESP-Skainet是乐鑫专门开发的语音助手工具。 (一)安装ESP-IDF 通过介绍可知,要使用ESP-IDF需要安装git
电路简单图解1.当天线接收到信号后,由于信号非常微弱,需要将信号放大,这就需要LNA(低噪声放大器)。然后通过一个射频段的带通滤波器,这里标注为Image Filter(镜像频率抑制滤波器),镜像频率指以载频为中心,与有用信号对称的频率,该频率上的噪声通过混频后会进到中频频率中。2.通过Image Filter后,信号进入MIXER(混频器)中与LO(本地振荡器)进行混频,并通过一个SAW(表面
