摘要

本文提出了一种基于隐马尔可夫模型和模式匹配技术的车载倒车报警或其他类似报警信号自动检测方法。该方法适用于嵌入式实时平台。该方法的目的是将其嵌入主动听力保护装置,帮助用户在低信噪比环境中检测警告信号。使用真实录音对性能进行评估,并给出结果。

Detection of vehicle mounted auditory reverse alarm using hidden Markov model
-This paper presents a method for automatically detecting vehicle mounted auditory reverse alarms, or other similar warning signals, based on hidden Markov model and pattern matching techniques. The method is designed for embedded realtime platforms. The purpose of the method is to embed it with active hearing protection devices, aiding the user in detecting warning signals in low SNR environments. Real recordings are used to evaluate the performance, and the results are presented.
