語音命令正迅速成為電子產品的主要功能。無論是您的智慧型手機、遙控器還是智慧家庭助手，語音辨識都可以讓您的聲音像您的雙手一樣高效。
聲控技術已經跟隨智慧揚聲器進入我們的家中，加快了我們周圍物聯網 （IoT） 的採用步伐。隨著物聯網語音控制技術不斷進入家庭環境，更多潛在的應用正在成為可能。
今天，我們將探討不斷增長的語音和語音辨識市場，討論製造商和產品製造商如何滿足對具有物聯網功能的語音設備的需求，並研究語音辨識應用如何對人類生活產生積極影響。
對語音命令的需求不斷增長
支持語音的設備正迅速成為人們離不開的物品，而且對它們的需求不會很快消失。事實上， 到 2025 年，語音和語音辨識市場預計價值將達到 27.16 億美元。
疫情刺激了語音助理的採用，因為企業和消費者都在尋找更簡單、更安全、更方便的方式與世界互動。即使生活最終恢復到新常態，大多數人仍會繼續使用語音助理及其語音設備。
製造商和產品設計人員面臨挑戰，尋找能夠與所需上市時間相匹配的理想硬體和軟體解決方案。然而，借助 Ambiq 最新的超低功耗解決方案，您可以快速將數十億台具有語音功能的未來物聯網設備推向市場。
製造商如何滿足市場需求
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.
透過語音辨識改善人類生活
有許多語音辨識應用程式可供消費者使用，尤其是在個人使用方面。多年來，智慧型手機一直在宣傳語音辨識和語音助理功能。最近，智慧感測器、智慧手錶和健康追蹤器已成為流行的穿戴式技術，可以更好地整合語音命令。設備感測器越來越多地可以精確偵測使用者的聲音，有些感測器能夠透過 頸部區域的皮膚振動 來識別聲音。
在智慧家庭中，語音辨識已經是語音設備、聲控、語音虛擬助理系統的熟悉功能。可以整合語音命令的設備的其他範例包括智慧遙控器和遊戲控制器。語音控制提供了一種免持方式來控制照明、窗簾、門鎖、氣候和智慧型裝置。隨著越來越多的設備能夠通過藍牙®或互聯網連接到網絡，房主可以使用智能手機從任何位置輕鬆訪問和控制家中的任何設備。
在醫療保健領域，語音辨識是用於豐富現有電子健康記錄系統的核心技術。醫生和醫務人員可以口頭說話和保存記錄，而不是依賴手動打字或書寫，從而實現更好的記錄保存和更集中的護理。在 COVID-19 大流行之後，隨著消費者尋求更可靠的解決方案，醫療保健領域對語音和語音識別的需求肯定會增加。
Ambiq 的永續解決方案
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.
