动态时间规整是语音识别中语音片段时间对齐和比较的成熟技术。本文介绍了一种用于计算动态时间扭曲算法的 CMOS 集成阵列处理器。它允许许多流行的变体,包括 LPC 和语音的频域表示。高速度是通过广泛的流水线、并行计算和多个模式的同时匹配来获得的。每个单词使用 40 个九分量 LPC 向量的实际应用允许每秒进行 10,000 次单词比较,或者等效地实时识别 10,000 个单词的词汇表。
Dynamic time warping is an established technique for time alignment and comparison of speech segments in speech recognition. This paper describes a CMOS integrated array processor for computing the dynamic time warp algorithm. It allows many popular variations including LPC and frequency domain representations of speech. High speed is obtained by extensive pipelining, parallel computation, and simultaneous matching of multiple patterns. A realistic application using 40 nine-component LPC vectors per word permits 10,000 word comparisons per second or, equivalently, real time recognition of a 10,000 word vocabulary.
