摘要： An apparatus and method for recognizing speech includes a memory for storing data representing a reference pattern composed of the combination of a word reference pattern and a silence pattern, and a calculator for calculating the differences between data representing the reference pattern and data representing input speech. The use of such a silence pattern in the reference pattern permits a word such as "other" to be distinguished from the word "mother".

摘要： Speech recognition is achieved using a normalized cumulative distance. A normalized Dynamic Programming (DP) value is calculated by dividing a cumulative path distance by an optimal integral path length. The path length is calculated iteratively by adding 2 if the warping path is diagonal or by adding 3 if the warping path is horizontal or vertical. Distance may be calculated by measuring a difference between input power and average power. The power difference is weighted by a coefficient (.lambda.) between 0 and 1. A Mahalanobis distance is then weighted by (1-.lambda.) and added to the weighted power difference.
摘要翻译：使用归一化的累积距离实现语音识别。通过将累积路径距离除以最优积分路径长度来计算归一化动态规划（DP）值。如果弯曲路径是对角线，则迭代地计算路径长度，如果弯曲路径是水平或垂直的，则通过加上2来计算路径长度。距离可以通过测量输入功率和平均功率之间的差异来计算。功率差由0和1之间的系数（λ）加权。然后通过（1-lambda）加权马哈拉诺比斯距离并将其加到加权功率差。

摘要： A method for encoding syllables of a language, particularly the Japanese language, and for facilitating the extraction of sound codes from the input syllables, for voice recognition or voice synthesis includes the step of providing a syllable classifying table, in which each syllable is represented by an upper byte code indicating the consonant part of the syllable and a lower byte code indicating the non-consonant part of the syllable. The consonants constitute a first category of data classified by phonetic features, while the non-consonants constitute a second category of data classified by phonetic features, so that the extraction of consonant or non-consonant sounds can be made by a search in only the first or the second categories. The encoding of diphthongs are made in such a manner that those containing the same vowel have the same remainder corresponding to the code of this vowel, when the codes are divided by the number of vowels contained in the second category, so that the extraction of a vowel from diphthongs can be achieved by a simple mathematical division.
摘要翻译：用于编码语言，特别是日语的音节的方法，以及用于便于从输入音节提取声音代码，用于语音识别或语音合成的方法包括提供音节分类表的步骤，其中每个音节由指示音节的辅音部分的高字节代码和表示音节的非辅音部分的低字节代码。辅音构成了以语音特征分类的第一类数据，而非辅音构成了以语音特征分类的第二类数据，因此可以仅通过搜索第一类搜索辅音或非辅音或第二类。双符号的编码是这样进行的，即当包含同一元音的那些元素具有与该元音的代码相同的余数时，当代码除以第二类别中包含的元音数量，从而提取来自diphthongs的元音可以通过简单的数学部分来实现。

摘要： A voice recognizing method apparatus in which an input voice is recognized by obtaining a similar pattern by comparing the input voice and voice standard patterns. Voice standard patterns are stored into a memory. A voice is inputted. Voice duration lengths and distances are calculated by performing matching processes between the input voice and the standard patterns. The distance is corrected in accordance with the voice duration length so that the voice duration length having the best matching result is used as a reference, or such that the distance is small as the voice duration length is long. A recognition result is determined in accordance with the corrected distance. The matching is executed by a word spotting method. The input voice to be matched and the voice standard patterns are expressed by voice characteristic parameters.

摘要： A speech recognition method and apparatus in which a speech section is sliced by the unit of a word by spotting and candidate words are selected. Next, in a second stage, matching is conducted by the unit of a phoneme. Consequently, selection of the candidate words and slicing of the speech section can be performed concurrently. Furthermore, narrowing of the candidate words is facilitated. Furthermore, since reference phoneme patterns under a plurality of environments are prepared, recognition of an input speech under a larger number of conditions is possible using a smaller amount of data when compared with the case in which reference word patterns under a plurality of environments are prepared.
