项目摘要

Speech material was chosen including photetically ballanced 216 words, 110 monosyllables, 70 short sentences, 11 interrogative sentences, 7 sentences for speech quality measurement, one folk tale, weather forecast sentences and narrative sentences. Speech samples were recorded onto digital audio tapes (DAT) based on the above material with ten male and ten female speakers. Noise sound in a computer room was recorded to investigate influence of noise to speech processing.Noise data of two hour duration was recorded onto DAT under 4 conditions of varying numbers and kinds of working machines.Speech data of the 20 speakers mentioned above (4 utterances for each item, 2 hours for each speaker, 40 hours in all) was checked by hearing and those of good speech and recording quality of 12 speakers (6 male and 6 female speakers, 24 hours in all) was selected among them. Master tapes for speech database was produced with start ID's and program numbers assigned to major items so that necessary items can be retrieved easily. Check lists were prepared which describes pronunciation and recording conditions in detail. One utterance of good quality from 4 repetitions was selected for 7 kinds of continuous speech data mentioned above and they were recorded on to CD-ROM. This would be the first attempt to create a CD-ROM speech database of Japanese sentence speech. Then best utterances of 110 monosyllables and phonetically balanced 216 words were also recorded onto CD-ROM.One of the major objectives of speech databases is to utilize them to develop various techniques of speech analysis, synthesis and recognition and to compare and evaluate them. Therefore, several kinds of speech analysis and recognition experiments have been performed. Some methods were proved to be useful for speech/non-speech discrimination and speech recognition under noise environments.

选择了语音材料，包括光学弹奏的216个单词，110个单音节，70个简短句子，11个疑问句子，7句话言语质量测量的句子，一个民间故事，天气预报句子和叙事句子。根据上述材料，将语音样本记录到数字音频磁带（DAT）上，其中有十位男性和十个女性扬声器。记录了计算机室中的噪声声音以调查噪声对语音处理的影响。在不同数量和工作机的4个条件下，将两个小时的持续时间记录到DAT上。对于每个演讲者，每个演讲者2个小时，总共40小时）通过听力进行检查，其中包括12位演讲者的良好语音和记录质量（6名男性和6位女演讲者，共24小时，共24小时）。语音数据库的主磁带是由启动ID和分配给主要项目的程序编号生成的，因此可以轻松检索必要的项目。准备了检查清单，该清单详细描述了发音和记录条件。上面提到的7种连续的语音数据选择了4种重复质量的一种质量，并将其记录到CD-ROM。这将是创建日语句子语音的CD-ROM语音数据库的首次尝试。然后，还将110个单音节和语音平衡的216个单词的最佳话语记录到CD-ROM上。语音数据库的主要目标之一是利用它们来开发各种语音分析，综合和识别的技巧，并比较和评估和评估它们。因此，已经进行了几种语音分析和识别实验。事实证明，某些方法可用于噪声环境下的语音/非语音歧视和语音识别。
