Description
図1は、実施形態1による音声画像再生システムの構成例を示す。このシステムは、音声データおよび画像データから音声および画像を再生するものであり、情報送信回路11および補聴器本体12を含む補聴器10と、信号処理回路21および画像再生回路22を含む音声画像処理装置20(例えば、テレビ、ドアホン,カーナビなど)とを備える。情報送信回路11は、補聴器10に対応する処理時間が示された遅延情報DD1を音声画像処理装置20に送信する。信号処理回路21は、遅延情報DD1に基づいて補聴器10に対応する遅延時間T103を設定し、音声信号S100を補聴器10に供給するとともに遅延時間T103で画像信号S200を遅延させて画像再生回路22に供給する。画像再生回路22は、画像信号S200から画像を再生する。補聴器本体12は、音声信号S100に補聴処理(聴覚を補助するための音声処理)を施して音声を再生する。なお、情報送信回路11は、補聴器本体12から分離されたもの(例えば、リモートコントローラ)であっても良い。この場合、情報送信回路11は、補聴器ユーザ(補聴器本体12を使用するユーザ)によるマニュアル設定に従って補聴器本体12による補聴処理を遠隔操作する補聴処理制御部をさらに含んでいても良い。また、情報送信回路11は、補聴器本体12と一体となって補聴器10を構成するものであっても良い。この場合、補聴処理制御部を含むリモートコントローラによって補聴器10を制御しても良い。さらに、信号処理回路21は、画像再生回路22から分離されたものであっても良いし、画像再生回路22と一体となって音声画像処理装置20を構成するものであっても良い。
遅延情報DD1に示された処理時間は、補聴器本体12において実行される処理の内容に基づいて算出できる。また、遅延情報DD1は、補聴処理時間以外の処理時間を示していても良い。例えば、遅延情報DD1は、補聴処理時間と伝送処理時間(信号処理回路21から補聴器本体12への音声信号S100の伝送に要する時間)との合計時間を示していても良い。また、伝送処理時間には、無線通信(例えば、ブルートゥース)の通信プロトコルを実行するために要する時間が含まれていても良い。例えば、伝送処理時間は、信号処理回路21による音声信号S100の送信処理に要する時間と、音声信号S100が信号処理回路21から送信されてから音声信号S100が補聴器本体12に到達するまでに要する時間と、補聴処理部105による音声信号S100の受信処理に要する時間との合計時間に相当する。このように構成することにより、補聴処理時間だけでなく伝送処理時間も画像信号S200の遅延時間で相殺できる。なお、遅延情報DD1には、処理時間以外の情報が含まれていても良い。例えば、遅延情報DD1にメーカ名や製品番号が含まれている場合、遅延情報DD1に含まれたメーカ名や製品番号に基づいて遅延時間を判断できるように音声画像処理装置20を構成しても良い。
また、遅延情報送信部102は、外部制御(例えば、補聴器ユーザによるマニュアル設定など)に従って遅延情報DD1に示された処理時間を変更した後に、遅延情報DD1を送信しても良い。例えば、遅延情報送信部102は、外部制御に従って遅延情報DD1に示された処理時間を増減しても良いし、遅延情報DD1に示された処理時間を外部制御によって設定された処理時間に置き換えても良い。同様に、遅延時間設定部103は、外部制御に従って遅延時間T103を変更しても良い。例えば、遅延時間設定部103は、外部制御に従って遅延時間T103を増減しても良いし、外部制御によって設定された遅延時間を遅延時間T103として出力しても良い。このように構成することにより、遅延時間T103(音声信号S100に対する画像信号S200の遅延時間)を任意に調整できる。これにより、補聴器ユーザは、聞こえにくさの程度など自身の聴覚の状態に応じて、遅延時間T103を適切に調整できる。なお、遅延時間T103は、遅延情報DD1に示された処理時間(補聴器に対応する処理時間)よりも短くても良い。
図2のように、音声画像処理装置は、音声信号S100を複数の補聴器に送信しても良い。図2に示した音声画像再生システムは、n個(nは2以上の整数)の補聴器10,10,…と、n個の補聴器10,10,…に対応する音声画像処理装置20aとを備える。n個の情報送信回路11,11,…は、それぞれ、遅延情報DD1,DD2,…,DDnを音声画像処理装置20aに送信する。遅延情報DD1,DD2,…,DDnは、それぞれ、第1番目の補聴器10,第2番目の補聴器10,…,第n番目の補聴器10に対応する処理時間(例えば、補聴処理時間)を示す。音声画像処理装置20aでは、遅延時間設定部103は、遅延情報DD1,DD2,…,DDnのそれぞれに示された処理時間に基づいて遅延時間T103を設定する。例えば、遅延時間設定部103は、n個の補聴器10,10,…のそれぞれに対応する処理時間の平均値を遅延時間T103として設定しても良いし、それらの処理時間の最大値に所定値(例えば、0.8)を乗算して得られる時間を遅延時間T103として設定しても良い。このように構成することにより、複数の補聴器ユーザのそれぞれにおいて音声認識と画像認識との時間差を均等に低減できる。これにより、補聴器ユーザのそれぞれにおいて視聴上の違和感を緩和できる。
図3は、実施形態2による音声画像再生システムの構成例を示す。このシステムは、情報送信回路11および補聴器本体32を含む補聴器30と、信号処理回路41および画像再生回路22を含む音声画像処理装置40とを備える。信号処理回路41は、図1に示した遅延時間設定部103および信号供給部104に加えて、識別信号出力部201をさらに含み、補聴器本体32は、図1に示した補聴処理部105および音声再生部106に加えて、識別信号検出部202をさらに含む。なお、信号処理回路41は、信号供給部104を含む信号処理モジュールと、遅延時間設定部103および識別信号出力部201を含む通信モジュールとに分離されていても良い。
以上の各実施形態において、補聴器と音声画像処理装置との間の信号伝送(音声信号S100の伝送や遅延情報DD1の伝送など)は、無線通信であっても良いし、有線通信であっても良い。例えば、実施形態2において、音声画像処理装置40と補聴器30とをコードで接続することにより、識別信号S201を補聴器30に伝送しても良い。
