Description
本發明是有關於一種控制系統與控制方法,且特別是有關於一種電子裝置的語音控制系統以及相關控制方法。
眾所周知,現在的電子裝置,例如手機或者智慧型電視,已經具備聲控功能。也就是說,該電子裝置可將使用者的聲音信號轉換為一相對應之指令,而電子裝置即可根據該指令來動作。
不可避免的,具聲控功能的電子裝置還是會出現無法辨識聲音的情況發生。歸咎其原因,電子裝置週邊環境的噪音是造成電子裝置無法成功進行辨識的一大因素。因此,如何有效地增加聲音辨識的成功率即為本發明所欲解決的問題。
本發明的目的是提出一種電子裝置的語音控制系統以及相關控制方法。
本發明係有關於一種電子裝置的聲控方法,包括下列步驟:於決定接收供控制該電子裝置之一聲音信號時,開啟一預設聲音接收週期並調降該電子裝置的一輸出音量;接收該聲音信號並據以執行對應之一指令;以及,於該預設聲音接收週期結束時,恢復該電子裝置的該輸出音量。
本發明係有關於一種電子裝置的聲控系統,包括:一錄音模組,接收並儲存一聲音信號;一處理模組,信號連接至該錄音模組,於決定接收一控制信號而開始一預設聲音接收週期時,控制該錄音模組接收並儲存該聲音信號;以及,一聲音播放模組,信號連接至該處理模組,於開始該預設聲音接收週期時,調降該電子裝置的一輸出音量。其中,於接收該聲音信號後,該電子裝置執行該聲音信號對應之一指令。
為了對本發明之上述及其他方面有更佳的瞭解,下文特舉較佳實施例,並配合所附圖式,作詳細說明如下:
本發明的實施方式係以具聲控功能的智慧型電視為例來作說明,但是並不限於智慧型電視。本發明的技術可以運用於所有具聲控功能的電子裝置。
請參照第1A圖,其所繪示為具聲控功能的智慧型電視示意圖。智慧型電視100可根據智慧型電視100上的麥克風110或者遙控器120上的麥克風122來接收使用者發出的聲音,並產生聲音信號。再者,智慧型電視100內部具有一聲控系統(未繪示),可將聲音信號轉換為聲音指令,而智慧型電視100即可執行聲控指令來進行頻道調整、音量調整...等功能。
請參照第1B圖,其所繪示為智慧型電視中的聲控系統示意圖。聲控系統130至少包括一處理模組(processing module)150、錄音模組160、聲音播放模組170。其中,當使用者欲進行聲控功能時,使用者利用一控制信號Svc,來通知聲控系統130使用者欲開始進行聲控並產生聲音信號Sa。處理模組150解析所接收的信號是否為控制信號,據以決定是否開始接收聲音訊號Sa。當麥克風110、122產生聲音信號Sa後,錄音模組160即將聲音信號Sa儲存於錄音模組160中。
接著,處理模組160中的辨識單元155分析錄音模組160內儲存的聲音信號Sa,並且對聲音信號Sa進行語音辨識以產生對應的指令。接著,處理模組150執行該指令,例如進行智慧型電視100的頻道調整、音量調整...等功能。
在一實施例中,假設指令係調整智慧型電視100的輸出音量,處理模組150即輸出音量控制信號Sm1至聲音播放模組170。而聲音播放模組170即可據以調高或者降低智慧型電視100喇叭的音量,以完成指令所對應的動作。
一般來說,使用者可以任何方式來啟動聲控系統130,以第1A圖與第1B圖的智慧型電視100為例,使用者可以按壓遙控器120上的聲控按鈕(VC)產生控制信號Svc,藉以啟動聲控系統130開始接收聲音信號Sa。
於一實施例中,當使用者按壓一次聲控按鈕(VC)並產生控制信號Svc後的一聲音接收週期(例如3秒鐘),聲控系統130即開始接收聲音信號Sa;於另一實施例中,當使用者持續按壓聲控按鈕(VC)並持續產生控制信號Svc既定長度的一段時間的情況成立,聲控系統130即開始接收聲音信號Sa。而於該聲音接收週期之後,聲控系統130停止接
收聲音信號Sa。
於另一實施例中,使用者也可以自行設定啟動聲控系統130的方式,例如使用者產生特定的手勢(gesture),當智慧型電視100的感測器(例如一影像感測器)偵測出使用者的特定手勢後即產生控制信號Svc來啟動聲控系統130開始接收聲音信號Sa。或者,使用者發出特定的聲音,當智慧型電視100的感測器(例如一聲音感測器)偵測出使用者特定的聲音後即產生控制信號Svc來啟動聲控系統130開始接收聲音信號Sa。
為了要提高聲音信號的辨識成功率,習知智慧型電視所配備的麥克風110、122係為指向性麥克風(directional microphone)。其可在特定的方向上具備高靈敏度以及抗噪音的功能,並可將使用者的聲音轉換成為高品質的聲音信號。而在辨識單元155中搭配複雜的演算法,即可提高聲音信號的辨識度。
請參照第2圖,其所繪示為本發明的聲控方法流程圖。聲控系統130開始接收聲音信號時(步驟S202),處理模組150調降智慧型電視系統100中聲音播放模組170的輸出音量(步驟S204)。接著,智慧型電視系統100中聲控系統130的錄音模組160接收聲音信號(步驟S206)。當聲音接收週期結束時,處理模組150恢復智慧型電視系統100中聲音播放模組170的輸出音量(步驟S210)並結束此聲音接收流程;反之,當聲音接收週期尚未結束時,錄音模組160持續接收聲音信號(步驟S206)。
由第2圖的說明可知,本發明最主要的目的是在聲控
系統130的聲音接收週期,調降智慧型電視的輸出音量。於最佳的情況下,可直接控制聲音播放模組170的輸出音量為靜音狀態(mute state),此時聲音信號具有最高品質。利用本發明的技術,智慧型電視的麥克風可以使用價格較低的一般型麥克風,也能夠接收高品質的聲音信號。
根據本發明的實施例,當使用者利用控制信號來啟動聲控系統而開始聲音接收週期。於聲音接收週期內,係直接降低(或者完全關閉)電子裝置的輸出音量,使得電子裝置接收最佳的聲音信號後能夠據以產生並執行相對應之一指令。當然,於聲音接收週期後,除了執行調整輸出音量的指令之外,電子裝置會恢復聲音接收週期之前的輸出音量。
於本發明一實施例中,除了控制智慧型電視本身輸出音量之外,本發明的聲音控制模組更可以控制智慧型電視之外其他裝置的輸出音量。請參照第3圖,其所繪示為智慧型電視中的另一聲控系統示意圖。與第1圖的差異在於聲控系統330中新增一外部通信模組380,而外部通信模組380信號連接於其他裝置,例如音響系統、收音機、電話、手機...等。於聲音接收週期內,處理模組150更可以產生另一音量控制信號Sm2至外部通信模組380,而外部通信模組380即據以控制其他裝置處於靜音狀態(或者降低輸出音量)。也就是說,使用者在聲音接收週期內所產生的聲音信號Sa具有最低的噪音干擾。當然,於聲音接收週期後,外部通信模組380也會控制其他裝置恢復聲音接收週期之前的輸出音量。
因此,本發明的優點係提出一種電子裝置的語音控制系統以及相關控制方法。於聲音接收週期內,直接降低(或者完全關閉)電子裝置的輸出音量,使得電子裝置接收最佳的聲音信號後能夠據以產生並執行相對應之指令。
綜上所述,雖然本發明已以較佳實施例揭露如上,然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者,在不脫離本發明之精神和範圍內,當可作各種之更動與潤飾。因此,本發明之保護範圍當視後附之申請專利範圍所界定者為準。
