Mark de Clercq，Dialogion Semicondutom的产品营销集团经理，将语音视雷竞技电竞平台为遥控器中的下一个大事

Keyboards, touch screens, gesture and motion control are now all commonplace in consumer electronic products. But all of these technologies come at a price, and not just in monetary terms. These human-machine input methods impact design complexity, component count, product size and, critically in battery-powered products, power consumption. And battery life has a huge impact on a product’s consumer appeal.

For remote control unit (RCU) applications, the interest in using voice commands is growing fast. It’s easy to see why. Microphones used in high volume consumer devices, whether electret types or MEMS versions, are simple, low cost devices manufactured by the billion each year. An operating frequency range of 100Hz to 10kHz is more than adequate for voice commands, so more advanced microphones are not needed. This again keeps costs low for the very price-sensitive RCU market.

另外两种因素使语音激活有效和吸引力。首先是近年来的语音识别软件在一定程度上取得了巨大的进步，因此由于半导体可获得的加工能力增加。也就是说，语音命令应用无水靠近令人苛刻的要求;雷竞技安卓下载它不太复杂，因为需要识别相对较少的词语。

第二个因素是许多可穿戴设备非常小，因此并非所有可携带的设备都有足够的空间来容纳传统的开关，触摸屏或其他输入方法。

继去年对话的TINY的推出之后，超低电源蓝牙智能解决方案 -SmartBond™ DA14580- we looked to extend the product family to make it easier for customers to implement voice commands in remote control units. SmartBond devices combine a Bluetooth low energy radio with an ARM® Cortex®-M0 application processor and intelligent power management. Product designers can access the ARM® processor via 32 GPIOs to create fully hosted applications.

对话的消费者音频的专业知识已经很好地建立 - 我们在过去几年里发了数亿个音频编解码器;它们从无绳电话到游戏设备的所有东西都使用。

因此，我们是一种自然的产品进化，用于我们创建SmartBond DA14582 - 通过将模拟音频编解码器与用于麦克风的本机支持的模拟音频编解码器对语音进行了优化的DA14580的版本。使用模拟MEMS或驻极麦克风，它真的是即插即用，我们提供了参考设计，显示了如何连接它。麦克风增益可以在2 dB步骤中从0 dB到+ + 30 dB调整。

我们计算出在典型的使用模型下，基于DA14582的语音控制，无论是设置的顶面框，智能电视，游戏还是智能家居应用程序都将从双NiMH电池中运行两年或更长时间。雷竞技安卓下载也许最重要的是，他们将很容易开发和制造，因为所有电子功能都将以单一的智能字体SoC交付。

SmartBond SoCs come in QFN packages with a 0.5mm pin pitch. This allows manufacturers to use very low cost PCB material (phenol-type PCB or single layer FR1 PCB) to lower the cost of the total system. This is critical in applications such as remotes where the PCB is fairly large compared to those in many other consumer electronics products.

IHS估计，到2018年将在每年制定5600万蓝牙智能遥控器。有令人兴奋的理由相信，这些大量和不断增长的比例将具有语音控制，因为它的成本更低，工作更好，并使电池持续更长时间。
