Abstract
(EN)
A speech recognition dictionary is created for words extracted from address data which is a lexicon subject to speech recognition, said extracted words having a frequency of appearance greater than or equal to a prescribed value. The speech recognition dictionary is compared with a time series of acoustic features of inputted speech, and a word string which is the most likely candidate for the inputted speech is identified from the speech recognition dictionary. The identified word string and the address data are compared for partial matches, and a partially matching term is treated as a speech recognition result.

Selon l'invention, un dictionnaire de reconnaissance vocale est créé pour des mots extraits de données d'adresse, lequel dictionnaire est un lexique sujet à reconnaissance vocale, lesdits mots extraits ayant une fréquence d'apparition supérieure ou égale à une valeur prescrite. Le dictionnaire de reconnaissance vocale est comparé à une série chronologique de caractéristiques acoustiques de paroles d'entrée, et une chaîne de mots qui est la candidate la plus vraisemblable pour les paroles d'entrée est identifiée dans le dictionnaire de reconnaissance vocale. La chaîne de mots identifiée et les données d'adresse sont comparées pour détecter des concordances partielles, et un terme concordant partiellement est considéré comme résultat de reconnaissance vocale.
(JA)
 音声認識対象の語彙である住所データから切り出した単語の出現頻度が所定値以上の単語について音声認識辞書を作成し、入力音声の音響特徴の時系列と音声認識辞書とを照合して、音声認識辞書から入力音声として最も確からしい単語列を特定し、特定した単語列と住所データとを部分一致照合して部分一致した語を音声認識結果とする。
