项目摘要

本研究は,自由発話文の認識のために新しい枠組の開発を目指したものであり,その方針として「連想関係」を中心にすえた.本研究は次の3つの段階から成る.1.大規模な言語データベースを解析し,その中に表れる連想関係やその他の言語情報を調査する.2.連想情報を用いて効率の良い認識のできるアルゴリズムを開発する.3.これらの結果を用いて,実際に稼働する実験システムを試作する.本年度の研究成果として,これらの段階のうち,(1)言語データベースの解析と,各種言語現象の調査,(2)連想関係を用いて認識を行うアルゴリズム「拡張RHA法」の開発の2つを行った.以下にその概略を述べる.1.言語データベースの解析: 分析に用いたデータベースは,日本音響学会研究用連続音声データベースの模擬対話テキストデータベースに含まれる書き起こしテキストである.この中の44対話(3633発話,19019文節)を分析対象とした.まず,このテキストに対して形態素解析を行ない,実質語3386個,機能語615個を抽出した.次に,この分析結果から,対話音声のための文節モデルを構築した.このモデルは,従来我々が文章朗読音声認識のために用いてきた文節モデルを拡張したものである.この文節モデルを用いて,データベース内の単語間の遷移確率,perplexity等を求めている.認識アルゴリズム「拡張RHA法」の開発: 連想関係を用いて連続音声中から単語認識を行なうアルゴリズム「拡張RHA法」を開発した.この認識法は,各種の情報を用いて単語を連想し認識するというものであり,従来のパターンマッチング的手法とは異なる.今回は,連想情報源として認識された音素のみを用い,従来的な連続音声認識の単語予備選択法として用い,その有効性を検証した.全く同じ枠組で,例えば単語の連続関係等の情報を有効に用いた音声認識が可能である.

The purpose of this study is to introduce information and information about the new information group. The purpose of this study is to introduce a new group of students who are interested in the study. In this study, the three stages of this study have become successful. 1. The large-scale model is full of words and expressions, and in the middle of the table, I want to talk about him. 2. If you want to do so, you can use your knowledge and knowledge to open your business. 3. The results show that the results are used, and that of the international farmers is used. The results of this year's research have been reviewed, and there has been a lot of progress in this year's research. (1) there has been a lot of analysis and analysis of the results of this year's research, and the results of this year's research have been reviewed in this year's research. (1) in the course of this year, the results of this year's research have been reviewed, and the results of this year's research have been reviewed. (1) there is a lot of analysis and analysis of the words and phrases. (2) if you want to use your knowledge and knowledge, you will start the RHA Law. The following is an overview of the following information. 1. The Japanese acoustics Society studies the use of sound links in the study of the sound system, and the Japanese acoustics society studies the use of sound links. There are 44 dialects (3633 dialects, 19019 texts) in the Chinese language. There are 3386 real-time users, and the machine can extract data from 615 users. For the second time, the results of the analysis were satisfactory, and the sound and sound of the speech were not good enough. Please tell me how to read the article. I need to know how to use the text. Please check the transfer rate between customers, perplexity, etc. Do not know that the RHA method starts: do you want to use the RHA method in the sound of the link. According to the Law, all kinds of customs use the same methods as you would like to know about each other, and to use the same method as you would like to use. This time, if you want to report on the source, you will know that the phoneme is used, and the sound of the link will be used by the method, so that you can have sex. We all share the same group, for example, if you are in a bad mood, you may not be able to use your voice.
