Abstract

PURPOSE: To provide data by voice to a voiced requirement by recognizing works generated by a driver and guiding data of a corresponding course by voice after a course from a current position to a destination is set.
CONSTITUTION: After a course from a current position to a destination is set by a course-setting means 103, words generated by a driver are recognized by a voice-recognizing means 105. A control means 106 obtains data of a course corresponding to the recognized words from the means 103. The composition of a voice guide sentence is controlled based on the obtained data. The course data are directed by a voice-generating means 107 by voice. For example, when the driver generates words related to next turning to the right (left), the means 106 guides a driver onto the turning direction and distance to the turning point. When the driver generates words related to the remaining distance to the destination, the remaining distance to the destination is directed by voice by a distance- calculating means 104 and the means 107. Accordingly, the driver can require desired data of his or her own will by voice wherever he or she desires. Data are thus provided by voice.

【実施例】図1は、本発明の一実施例の構成を示すものである。 DETAILED DESCRIPTION FIG. 1 shows the structure of an embodiment of the present invention. 図1において、101は車両の現在位置を推定する車両現在地推定手段、102は目的地を設定する目的地設定手段、103は現在地から目的位置までの走行経路を設定する経路設定手段、104は現在地から目的地までの残り行程距離を算出する距離算出手段、105 In Figure 1, the vehicle current position estimation means 101 for estimating the current position of the vehicle, destination setting means for setting a destination 102, route setting means for setting a travel route to the target position from the current position is 103, 104 are here distance calculation means for calculating the remaining travel distance to the destination from, 105
は不特定話者音声の複数語彙を認識する音声認識手段、 Speech recognition means recognizes the multiple vocabulary of unspecified speaker voice,
106は音声認識手段により認識した語彙に対応する経路情報を経路設定手段より取得し、音声案内の文構成を制御する制御手段、107は経路に関する各種情報を音声で案内する音声発生手段である。 106 acquired from the route setting unit route information corresponding to the vocabulary recognized by the voice recognition means, control means for controlling the sentence structure of the voice guidance, 107 is a sound generating means for guiding various kinds of information about the route by voice.

【0010】次に、上記実施例の動作について説明する。 [0010] Next, the operation of the above embodiment. 経路設定手段103により現在地から目的地までの経路が設定された後に、運転者が発生した語彙を音声認識手段105が認識し、制御手段106が認識した語彙に対する経路情報を経路設定手段103より取得する。 After the route from the current position to the destination is set by the route setting unit 103, a vocabulary driver occurs recognized by the speech recognition unit 105, obtains route information for vocabulary control unit 106 recognizes from the route setting unit 103 to.
取得した情報に基づき、音声案内の文構成を制御し、音声発生手段107により経路情報を音声で案内する。 Based on the acquired information, to control the statements configuration of a voice guidance to guide voice route information by voice generation means 107. 例えば運転者が次の右左折に関する語彙(例えば「次はどっち方向」)を発声した場合、音声発声手段106により右左折の方向、右左折までの距離(「500メートル先右方向です。」)を案内する。 For example if the driver has uttered vocabulary for the next right turn (for example, "next Which direction"), the right turn direction, ( "500 meters right.") Distance to the right or left turn by speech utterance means 106 the guide. また、運転者が目的地までの残り行程距離に関する語彙(例えば「あと何キロ?」)を発声した場合には、距離算出手段104と音声発生手段106により目的地までの距離(「残り10キロです。」)を案内する。 In addition, when the driver uttered a vocabulary for the remaining travel distance to the destination (for example, "after many kilometers?"), The distance by the distance calculation means 104 and the sound generating means 106 to the destination ( "The remaining 10 kg is. ") to guide the.

【0011】なお、目的地までの距離に加え、目的地までの予想所要時間を算出する所要時間算出手段を設け、 [0011] Incidentally, in addition to the distance to the destination, it provided the required time calculating means for calculating a predicted travel time to the destination,
この音声認識手段により残り所要時間に対する語彙を認識した場合に、上記音声発生手段により予想される所要時間を案内することも、上記と同様に行うことができる。 When recognizing a vocabulary for the remaining duration by the speech recognition means, to guide the required time predicted by the sound generating means can also be performed in the same manner as described above.

【0012】 [0012]

【発明の効果】本発明は上記実施例から明らかなように、運転者が目的地までの経路に関する情報を欲する場合に定められた語彙を発声することにより、音声認識手段が語彙を認識し、音声発生手段が語彙に対応する情報を音声で提供する。 According to the present invention as is clear from the above examples, by the driver pronounces a vocabulary defined when wants information about the route to the destination, the speech recognition means recognizes the vocabulary, providing voice information sound generation means corresponds to the vocabulary. したがって運転者の意志により得たい情報を得たい時に音声で要求でき、また音声による情報が提供されるので、あたかも運転助手が同乗して経路を案内してくれるような効果を有する。 Thus it can request a voice when it is desired to obtain information to be obtained by the driver's will, and because the information by voice is provided, though the operation assistant has the effect that us to guide the route and passenger. また不必要な音声案内がされることがなく、うるさいと感じることがなくなる。 Also without unnecessary voice guidance is, it is not necessary to feel noisy. また音声対話により経路情報を得るため、運転者は画面を見て進路を確認する必要がなく、視線の移動がなくなり運転に集中でき、安全性が向上するという効果を有する。 Also for obtaining routing information by voice dialogue, the driver does not need to confirm the path by looking at the screen, can concentrate on driving eliminates movement of the line of sight has the effect that the safety is improved.

【0013】なお、音声認識手段は不特定話者の音声を認識するため、運転者は前もって自分の声を登録する必要がなく、使用開始にあたっての操作の負担を大幅に軽減できる。 [0013] In addition, the speech recognition means for recognizing the voice of an unspecified speaker, the driver does not need to pre-register their voice, can greatly reduce the burden on the operation of when the start of use.
