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.

语音材料的选择包括216个单词，110个单音节，70个短句，11个疑问句，7个语音质量测量句，一个民间故事，天气预报句和叙事句。根据上述材料，将10名男性和10名女性说话者的语音样本记录到数字录音带（DAT）上。为了研究噪声对语音加工的影响，在计算机房内记录了噪声声，并在四种不同机器数量和种类的条件下，将两小时的噪声数据记录在DAT上，得到了上述20人的语音数据（每个项目4次发言，每名发言者2小时，通过听力检查，从中选出12名演讲者（6男6女，共24小时）的演讲和录音质量良好。制作语音数据库的母带时，将起始ID和节目编号分配给主要项目，以便可以容易地检索必要的项目。编制了详细描述发音和录音条件的检查表。从上述7种连续语音数据中，从4次重复中选出一个质量较好的语音，并将其记录在CD-ROM上，这将是创建日语句子语音CD-ROM语音数据库的第一次尝试。然后将110个单音节和216个语音平衡词的最佳发音记录在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、合成和识别技术，并对它们进行比较和评价。因此，已经进行了几种语音分析和识别实验。一些方法被证明是有用的语音/非语音歧视和语音识别噪声环境下。
