语音命令正迅速成为电子产品的主要功能。无论是智能手机、遥控器还是智能家居助手，语音识别都能让你的声音像双手一样高效。
声控技术随着智能扬声器进入我们的家庭，加快了我们身边物联网（IoT）的应用步伐。随着物联网语音控制技术不断进入家庭环境，更多的潜在应用成为可能。
今天，我们将探讨语音和语音识别市场的崛起，讨论制造商和产品制造商如何满足对具有物联网功能的语音设备的需求，并研究语音识别应用如何对人类生活产生积极影响。
语音指令的需求不断增长
语音设备正迅速成为人们生活中离不开的物品，而且对它们的需求不会很快消失。事实上，预计到 2025 年，语音和语音识别市场的价值将达到 271.6 亿美元。
由于企业和消费者都在寻找更简单、更安全、更方便的方式与世界互动，因此大流行病刺激了语音助手的采用。即使生活最终恢复到新常态，大多数人也会继续使用语音助手和语音设备。
制造商和产品设计师在寻找理想的硬件和软件解决方案时面临着挑战，而这些解决方案又必须与所需的上市时间相匹配。然而，有了 Ambiq 最新的超低功耗解决方案，您就可以快速将数十亿台具有语音功能的未来物联网设备推向市场。
制造商如何满足市场需求
With the demand for voice-enabled products predictably rising, more brands are looking to add voice functionality to devices such as smartwatches and TV remotes. Until recently, the compact size and the power constraints presented real design challenges. However, with the introduction of the new Ambiq Voice-on-SPOT® (VoS) Kit, manufacturers can integrate voice-command into their IoT devices with faster time-to-market. The first Ambiq VoS Kit is built on the Apollo3 Blue Plus MCU, enabling Always-on-Voice (AoV) functionality in battery-powered devices.
The Apollo3 Blue Plus Voice-on-SPOT Kit facilitates demos, evaluations, and the development of ultra-low power audio and voice capabilities on the Ambiq SoC. These tools enable manufacturers and product developers to add a reliable voice UI (user interface) in a compact, battery-powered device. In addition, the Ambiq VoS Kit has a robust functionality, as it provides always-on voice capability with options for one or two microphones, signal processing, wake word/command detection, codec, and Bluetooth Low Energy communication.
Furthermore, the Ambiq VoS Kit delivers a complete ultra-low power solution at the MCU and system levels with its ultra-low power consumption. Depending on the application requirements and customer aspirations, the Kit can extend the battery life up to a year or more, on standard alkaline or lithium batteries. Compared to a standard Arm® Cortex®-M4 core, Ambiq’s patented SPOT® technology provides up to 10x lower active power consumption.
利用语音识别技术改善人类生活
有许多语音识别应用程序可供消费者使用，尤其是在个人使用方面。多年来，智能手机一直在宣传语音识别和语音助手功能。最近，智能传感器、智能手表和健康追踪器作为流行的可穿戴技术出现，可以更好地整合语音命令。越来越多的设备传感器可以精确地检测到用户的声音，有些甚至可以通过颈部皮肤的振动来识别声音。
在智能家居中，语音识别已经是人们熟悉的语音设备、声控和语音虚拟助理系统的一项功能。其他可集成语音命令的设备包括智能遥控器和游戏控制器。语音控制为控制照明、窗帘、门锁、气候和智能设备提供了一种免提方式。随着越来越多的设备能够通过蓝牙® 或互联网连接到网络，业主可以在任何地点使用智能手机轻松访问和控制家中的任何设备。
在医疗保健领域，语音识别是一项用于丰富现有电子健康记录系统的核心技术。医生和医务人员可以用语言代替人工打字或书写，以口头方式进行记录，从而更好地保存记录，提供更有针对性的医疗服务。COVID-19 大流行之后，随着消费者寻求更可靠的解决方案，医疗保健领域对语音识别的需求肯定会增加。
Ambiq 的可持续解决方案
Ambiq was founded in 2010 with the mission to foster a cleaner, greener, and safer environment where mobile and portable devices could either reduce, or eliminate their total power consumption from the batteries. Ambiq has been laser-focused on inventing and delivering the most revolutionary System on Chip (SoC) solutions in the market for the last ten years. Through the advanced Sub-threshold Power Optimized Technology (SPOT) platform, Ambiq has helped many leading manufacturers worldwide create products that can operate for days, months, and sometimes years, on a lithium battery or a single charge.
