語音搜索將語音識別技術與搜索引擎關鍵字查詢相結合,使用戶能夠說出問題而不是鍵入問題。該軟件提取所聽到的內容,查詢一個或多個搜索引擎,並提供相關答案。
語音搜索越來越受歡迎,全球每天有數百萬用戶提交多個基於語音的查詢。他們使用語音搜索來獲取當地天氣預報,檢查他們的股票投資組合,回答日常問題等等。隨著公司發布新的支持語音搜索的虛擬助手,並且用戶學會優化查詢以獲得更好的結果,該列表還在不斷擴大。
業內分析師認為,在2019年或更早之前,語音搜索將佔直接搜索引擎流量的20%以上,並且這一數字有望增長。
語音搜索和虛擬助手是不同的但相關的技術。語音搜索是兩者中比較簡單的一個,但它是當今虛擬助手的許多高級功能的關鍵貢獻者,例如Amazon Alexa,Apple Siri,Google Assistant和Microsoft Cortana。
語音搜索描述了系統理解口語單詞,向搜索引擎提交相關問題並將結果呈現給用戶的過程。語音搜索可以單獨運行,也可以在虛擬助手中運行,虛擬助手通常還可以執行其他任務,例如日曆計劃,家庭設備管理等。
語音搜索的核心是語音識別技術,該技術可以追溯到1960年代初。但是,它在自然語言理解方面取得了進步,即係統能夠根據歷史,上下文以及如何說出單詞含義來理解單詞含義的能力,從而使當今的語音搜索和虛擬助手工具成為可能。當設備了解到“這個週末要下雨嗎?”關於即將到來的周六至週日的當地天氣預報,它使用自然語言理解來連接概念。
語音搜索最初是在智能手機和類似的手持設備中普及的,在這些智能手機和手持設備中,鍵入搜索詞可能會帶來不便。用戶喜歡簡單地通過說“英超聯賽中有多少支球隊?”來獲得快速答案。或“ Albuquerque在哪裡?”,語音搜索迅速被公眾接受,導致軟件製造商也將該技術嵌入PC操作系統。
最新的語音搜索/虛擬助手趨勢是所謂的智能設備或智能揚聲器,它們主動偵聽語音搜索查詢(或其他命令)並大聲說出結果。示例包括Google Home,Amazon Echo和Apple HomePod。包括Lenovo Smart Display在內的較新的設備也增加了屏幕,因此也可以直觀地顯示語音搜索查詢的答案。可視搜索結果被認為是交通更新,教學材料等的更好替代方法。
鍵入查詢曾經是向搜索引擎提交問題的唯一方法。但是,隨著語音搜索的出現,不再需要打字。這只是一種方法。這種變化是如此重要,以至於如今,長期使用的“文本搜索”一詞有了新的含義,成為區分類型查詢和口頭查詢的一種方式。
與任何技術一樣,語音搜索也有優點和缺點-尤其是通過Alexa,Siri,Cortana和Google Assistant等虛擬助手服務啟用了語音搜索。以下是語音搜索的一些優缺點:
