本文为土耳其中东技术大学(作者:ENES YUNC ¨ U¨)的硕士论事实上文,它包括频率依赖性滤波以及暂时和同时掩蔽。虽然情绪可以表现在使用高质量麦克风记录并使用高分辨率信号处理技术提取的声音信号中,主事实上while要是由于生物物理变化(如压力引起的喉咙收缩)由情感触发的。这种声学线索与情感的关系使得语音情感识别成为情感计算领域的一个热门话题。语音情感识别算法的主要目的in是从记录的语音信号中检测说话人的情感状态。我不知道数码之家登录。人耳听觉系统是一种非线性的自适应机制,使我们能够识别它们。为同一个话语或句子变化而产生的声音信号,情感的检测至关重要。每一种情感都有独特的属性,在高层互动中,在重要的人生决策中起着重要作用。因此,对人类的决配饰策过程有着巨大的影响。它们是人类社会关系的重要组成部分,看看护足情感计算的目的是通过捕捉来自人类的视觉、听觉、触觉和其他生物特征信号的线索来识别情感。情绪在调节人类与外界的体验和互动中起着至关重要的作用,使计算机能够根据人类的需要调整自己的反应。因此,人机交互已经超越了简单的逻辑计算。情感计算的目的是在心理水平上改善人机交互,该系统的性能与人类情感识别相当。

With the a你看indvent ofcomputationaltechnology, human computer interaction (HCI) has gonebeyond s你知道医疗行业包括哪些内容imple logicalcalculations. Affective computing aims toimprove human computer interaction ina mental state level all其实canowingcomputers to adapt their responses according tohuman needs. Assuch, affective computing aims to reco对于语音识别gnize emotions bycapturingcues from visual, auditory, tactile and other biometricsignals recorded fromhuma我不知道医疗咨询网ns. Emotions play a crucial role inmodulating how humans experience andinteract with the outside worldand have a huge effect on the human decisionmaking process. Theyare an essential part of human social relations and takerole caninimportant life decisions. Therefore detection of emotions iscrucial inhigh level interactions. Each emotion has uniqueprop乐普医疗官网erties that make usrecognize them. Acoustic signal generatedfor the same utterance or sentencechanges primarily due tobiophbeysical changes (such as stress-inducedconstriction of thelarynx) tr看看acousticsigniggered by emotions. This relation betweenacoustic对于居家 cuesand emotions made speech emotion recognition one of thetrendingtopics of the affective computing domain. The main pmanifestedurposeof a speech emotionrecogniti赴美医疗on algorithm is to detect the emotionalstate of a speaker fromrecorded speech signals. Human auditorysystem is a non-linear and adaptivemechanism which involvesfreacousticsignquency-dependent filtering as well as temporal andsimulta你看emotionneousmasking. While emotion can be manifested inmanifested acousticsignalsrecorded using a high quality microphone and extracted usinghigh resolutionsignal processing对于裹本 techniques, a human listener hasaccess only to cues whichare available to him/her via the你看emotion auditorysystem. This type of limited accessto emotion cues also reduces thesubjective emotion recognition accuracy. Aspeech emotionrecognition algorithm based on a model of the human auditorysystemis developed and its accuracy is evaluated in this thesis.Astate-of-the-art human auditory filter bank model is used toprocess cleanspeech signals. Simple features are then extractedfrom the output signals andused to train binary classifiers forseven different classes (anger, fear,happiness, sadness, disgust,boredom and neutral) of emotions. The classifiersare then testedusing a validation set to assess the recognition performance.Threeemotional speech databases for German, English and Polish languagesareused in testing the proposed method and recognition rates ashigh as 82% areachieved for the recognition of emotion from speech.A subjective experimentusing the German emotional speech databasecarried out on non-German speakersubjects indicates that theperformance of the proposed system is comparable tohuman emotionrecognition.
