Abstract
Description
以下、本発明に係る発話機器の発話テスト方法、発話テストサーバおよび発話テストシステムの実施の形態1について、適宜図面を参照しながら詳細に説明する。
発話機器20は、発話機能を有する機器である。本実施形態の発話機器20は、発話機能を有する家電(発話家電)を含む。家電とは、家庭用電化製品の略称である。発話機器20は、家庭で用いられる電子機器であれば任意の種類の機器であってもよく、例えば、家庭で使うテレビ、冷蔵庫、空気調和機、洗濯機、掃除ロボット、音響機器(スマートスピーカを含む。)、照明、給湯器、インターホンなどの電気器具が含まれる。発話機器20は、「民生用発話機器」、「発話家電」と称してもよい。発話機能とは、スピーカを用いて人間の言語を含む音声を発する機能という。発話機能は、人間の言語を含まない、ビープ音、ブザー音、アラーム等の音のみを発声する機能とは異なり、人間の言語を用いてより多くの情報をユーザに伝達することができる。発話家電としての発話機器20はそれぞれの家電機能を発揮するように構成されている。例えば、空気調和機である発話機器20は、圧縮機と熱交換器と室内温度センサとを含み、制御空間において冷房、暖房、および除湿の機能を発揮するように構成されている。また、例えば、掃除ロボットである発話機器20は、バッテリと集塵機構と移動機構と物体検知センサとを含み、移動可能な範囲内で移動しながら掃除するように構成されている。
端末装置30は、発話機器20に関連する装置である。例えば、発話機器20のコントローラであってもよく、複数種類の家電製品を同時に管理・制御できるコントローラであってもよい。また、端末装置30は、発話機器20との間でデータ通信を行うことができる情報端末、例えば、専用の関連アプリケーション32が組み込まれたスマートフォン、携帯電話、モバイルフォン、タブレット、ウェアラブル装置、コンピュータなどであってもよい。発話テストサーバ10または機器制御部22は、端末装置30を介してユーザが入力した設定または指令を取得することができる。一般的には、端末装置30はグラフィックユーザインタフェース(graphical user interface、GUI)を表示するためのディスプレイを含む。ただ、音声ユーザインタフェース(voice User Interface、VUI)を介してユーザと相互作用する場合、ディスプレイの代わりに、またはディスプレイに加えて、端末装置30はスピーカとマイクとを含んでもよい。
情報元装置40は、発話機器20が発話する内容に関連する情報源である。情報元装置40は、発話機器20が設けられた家庭内の別の機器(家電)であってもよい。情報元装置40が別の機器である場合、本開示では、情報元装置40は情報元機器(情報元家電)とも呼ばれている。情報元機器は発話機器20であってもよく、発話機能を有しない機器であってもよい。情報元機器は、その運転状態などの機器情報(家電情報)を発話テストサーバ10に送信し、発話テストサーバ10は、受信した機器情報に基づいて発話テストのテスト内容を設定してもよい。また、発話テストの終了後、発話機器20の通常の使用中に、情報元機器は機器情報を発話テストサーバ10または別のサーバに送信し、発話テストサーバ10または当該別のサーバは受信した機器情報に基づいて発話機器20に発話させてもよい。機器情報の例としては、例えば、情報元機器の起動状態、運転モード、異常情報などが挙げられる。
外部情報源50は、発話機器と直接的に関わらないサービスに関する情報、例えば、気象情報や、宅配便の配送状況に関する情報を提供する情報源である。発話テストサーバ10は、外部情報源50から取得する情報に基づいて、発話テストのテスト内容を設定してもよい。発話テストサーバ10、端末装置30、または他のサーバは、発話テストの終了後、発話機器20の通常の使用中に、外部情報源50から取得する情報に基づいて、発話機器20に発話させてもよい。
発話テストサーバ10は、少なくとも1つの発話機器20に対して、人間の言語を含む音声データまたは映像データを用いて、発話テストを行うサーバである。1つの実施例において、発話テストサーバ10は、インターネットを経由して少なくとも1つの発話機器20に接続して、発話テストについて制御することができる。同じ家庭または同じ売り場に設けられた複数の発話機器20に対して、発話テストサーバ10は一度にこれらの複数の発話機器をテストすることができる。
サーバ記憶部12は、種々の情報や制御プログラムを記録する記録媒体であり、サーバ制御部14の作業領域として機能するメモリであってもよい。サーバ記憶部12は、例えば、フラッシュメモリ、SSD(Solid State Device)、ハードディスク、RAM、その他の記憶デバイス又はそれらを適宜組み合わせて実現される。サーバ記憶部12は、発話テストサーバ10内部のメモリであってもよく、発話テストサーバ10と無線通信または有線通信にて接続されているストレージ装置であってもよい。
発話テストサーバ10のサーバ制御部14は、発話テストサーバ10全体の制御を司るコントローラである。サーバ制御部14は、プログラムを実行することにより所定の機能を実現するCPU、MPU、GPU、FPGA、DSP、ASICのような汎用プロセッサを含む。サーバ制御部14は、サーバ記憶部12に格納された制御プログラムを呼び出して実行することにより、発話テストサーバ10における各種の制御を実現することができる。また、サーバ制御部14は、サーバ記憶部12と協働してサーバ記憶部12に記憶されたデータを読み取り/書き込みを行うことができる。サーバ制御部14は、ハードウェアとソフトウェアの協働により所定の機能を実現するものに限定されず、所定の機能を実現する専用に設計されたハードウェア回路でもよい。
サーバ通信部16は、サーバ制御部14と協働して、発話機器20や、端末装置30、情報元装置40、外部情報源50等とインターネットパケットを送受信する、すなわち、通信することもできる。例えば、発話テストサーバ10は、サーバ通信部16を介して端末装置30から指令を受信してもよく、発話機器20に対して指示を送信してもよく、情報元装置40または外部情報源50から情報を受信してもよい。サーバ通信部16または機器通信部23は、発話テストサーバ10と、発話機器20と、端末装置30と、情報元装置40と、外部情報源50との間において、Wi-Fi(登録商標)、IEEE802.2、IEEE802.3、3G、LTE等の規格にしたがい通信を行い、データの送受信を行ってもよい。インターネットの他、イントラネット、エキストラネット、LAN、ISDN、VAN、CATV通信網、仮想専用網、電話回線網、移動体通信網、衛星通信網等、赤外線、ブルートゥース(登録商標)と通信してもよい。
発話テストサーバ10は、サーバ記憶部12およびサーバ制御部14を用いて、発話機器の発話テスト方法を実行する。図2は、実施の形態1における発話機器の発話テスト方法のフローチャートであり、発話機器の発話テスト方法は以下のステップS100~ステップS400を含む。図3は、実施の形態1における発話機器の発話テスト方法の一例のシーケンス図であり、図2のフローチャートに対応する。
<発話テストサーバ10が複数のサーバによって構成されている場合>
実施の形態2において、発話テストサーバ10は、異なる役割を持つ複数のサーバによって構成されている。
<テスト機器が複数である場合>
実施の形態3において、テスト機器が複数に設定され、発話テストサーバ10は複数のテスト機器に順に発話テストをさせる。
<テスト失敗の場合>
実施の形態4において、例えば発話テストに障害が発生することによってテストが失敗する場合、サーバ制御部14はテスト失敗したことをユーザに通知することができる。また、サーバ制御部14は、失敗原因を特定しようとし、特定できた失敗原因をユーザに通知してもよい。
<設定変更で再テストの場合>
実施の形態5において、ユーザは発話テストの結果を受け、発話設定を変更してからテストを再度行うことができる。
<発話テスト中に追加情報を発話させる場合>
実施の形態6において、発話機器20の発話機能についての情報をより多くユーザに提供するように、発話テスト中に追加情報をテスト機器に発話させるまたは端末装置30に表示させることができる。
<発話文言を端末装置に表示させる場合>
実施の形態7において、発話前に、テスト内容の発話文言(テキスト)を端末装置30に表示させることができる。よって、テストを実際に行う前に、ユーザはどんな文言が発話されるかをより容易に理解でき、発話テストに心構えできる。
発話テストサーバ10と通信する端末、例えば、発話機器20または端末装置30は、上述したような発話テストを実行するために使用されるプログラムを有する。
