虛擬助手可以幫助我嗎?

與人工助手相似,虛擬助手是一種軟件代理,可以響應直接命令,預設時間表或通過嘗試根據用戶的過去需求預測用戶的即將到來的需求來執行智能手機或計算機任務。如果您曾經“說過”電話或PC來啟動Web搜索或其他活動,則可能使用虛擬助手來完成。

Google Assistant,Microsoft Cortana,Apple Siri和Amazon Alexa是流行的虛擬助手的示例。虛擬助手軟件已經使用了20多年,但是隨著智能手機的推出,該技術真正起飛了,並且現在已經內置在許多PC操作系統中。虛擬助手也是新一代“智能揚聲器”和“智能顯示器”的關鍵組件,它們看起來像家具配件,但可以響應語音輸入提供信息或執行任務。

虛擬助手可以做什麼?

虛擬助手可以完成您可以自己完成的幾乎任何與智能手機或PC相關的離散任務,並且列表越來越多。從安排會議到發送消息再到檢查天氣,虛擬助手在首次啟動時通常具有一組令人印象深刻的功能-他們可以在學習常用活動和偏好時添加新功能。

當然,虛擬助手只能與系統上的應用程序或已註冊的基於雲的服務一起使用。但是他們通常會在需要時要求澄清;例如,如果您使用兩個電子郵件程序,則助手可能會問您應該使用哪個電子郵件程序發送給特定的個人,然後記住您的選擇並在下次建議相同。

大多數用戶從使用虛擬助手開始日常電話和PC管理任務以及網絡搜索開始。但是,當與其他工具和服務集成時,虛擬助手幾乎可以做任何事情:

  • 控制恆溫器,燈和鎖
  • 發送電子郵件/短信或發起呼叫
  • 在線購買物品(一次性或按計劃)
  • 找到丟失的智能手機或其他設備
  • 檢查交通狀況並映射旅行路線
  • 大聲閱讀書籍或報紙
  • 安排與同事開會
  • 識別歌手和歌曲名稱
  • ...列表繼續

虛擬助手如何工作?

根據您使用的硬件,虛擬助手可以接受語音命令(在智能手機上常見),文本輸入(在PC上也可以接受語音命令)上常見的輸入,甚至可以分析照片或條形碼。響應-可以是從網絡搜索結果到流量更新到會議確認的任何內容-都取決於硬件:例如,智能揚聲器只能提供聽覺響應,而智能手機,PC和智能顯示器可以在聽覺和/或視覺上做出響應。

與語音命令一起使用時,虛擬助手通常需要“喚醒字”或激活短語來啟動。在大多數情況下,這些詞是助手的名字,即使與其他更多對話性詞結合使用也可以工作。因此,Google Assistant用戶說“ OK Google”或“ Hey Google”,Microsoft用戶說某種形式的“ Cortana”,Apple用戶說“ Siri”或“ Hey Siri”,而Amazon用戶說“ Alexa”或類似名稱。如果預編程的喚醒詞不符合您的需求(想像一下與名叫Alexa的人在家中使用Alexa的挑戰),則可以將大多數虛擬助手配置為偵聽不同的激活詞。

有關虛擬助手的其他事實

儘管虛擬助手具有很大的實用性和受歡迎度,但還是有一些局限性。我們在這裡介紹的所有內容都不應被視為反對使用虛擬助手的理由;它們確實有用,並且在世界範圍內越來越受歡迎。而是,在第一次使用虛擬助手之前,將此列表視為只是一些“要了解的其他事項”:

  • 虛擬助手的大部分工作都依賴於基於Web和雲的服務(分析語音命令,獲取搜索結果,安排約會等)。因此,如果沒有強大的Internet連接,它們的用途將受到限制。
  • 在語音激活模式下使用時,虛擬助手會受到語音識別和自然語言理解軟件的限制。隨著時間的流逝,您可能會學會使用單詞和命令的子集,以最清楚地將您的意圖傳達給設備。
  • 重複使用是幫助虛擬助手學習更好地滿足您的常見查詢和命令的關鍵。結果會隨著時間的推移而改善,因此您可能需要花一些時間才能說出“明天給約翰和我打9個洞”並對成功充滿信心。[在這個極端的例子中,成功涉及到第二天檢查您和您丈夫約翰的日曆,登錄您喜歡的高爾夫球場的預訂系統,並在兩個人都有空時簽約兩個人同時打9個洞。]
