基于电子声门仪的语域（register）发声产出实验：声学与EGG信号同步采集及函数型主成分分析

方法说明：该实验以缅甸孟语（Burma Mon）的高、低两类语域对立为研究对象，对17名母语者在载体句中朗读目标词的过程进行头戴式麦克风声学录音，同时使用 Laryngograph Ltd 的 EGG-D800 电子声门仪同步采集电子声门图（EGG）信号。随后利用 Praat/praatdet 从 EGG 信号提取开商（OQ），利用 PraatSauce 提取基频 f0、共振峰 F1/F2、H1*-A3*、CPP 等声学参数，经 MATLAB 时间归一化与平滑后，采用函数型主成分分析（FPCA）结合线性混合效应模型考察两类语域在时间维度上的差异，揭示语域主要由 f0 与嗓音音质的协同变化实现。

实验仪器：电子声门仪 EGG-D800；头戴式麦克风；USB 数字音频接口；笔记本电脑（运行 SpeechRecorder 录音软件）

实验步骤

1. 被试招募与刺激材料准备

   说明：招募17名缅甸孟语母语者（6女11男，21–53岁），来自缅甸孟邦不同镇区；编制55个目标词词表，以孟文并附缅文翻译在笔记本电脑上呈现。

   关键点：被试须为目标方言母语者；目标词须覆盖高、低两类语域并在元音、声母等条件上平衡。

2. 声学与EGG信号同步录制

   说明：2023年10月在泰国龙仔厝府的孟族社区场所进行录制。被试在载体句“ʔare̤ __ ʔoa mo̤ik kɤ̤ʔ hɑm”（我想说 __ 这个词）中朗读目标词，每词重复2–3次；使用头戴式麦克风经 USB 数字音频接口以 44.1 kHz 采样，录音软件为 SpeechRecorder；同时通过 EGG-D800 电子声门仪采集 EGG 信号。

   关键点：EGG 电极须紧贴甲状软骨两侧并保持稳定接触；声学与 EGG 通道须严格同步；载体句可控制语境与语速一致。

3. 语音切分与标注

   说明：使用 Praat 进行强制对齐并人工校正目标音节的边界，标注声母爆发、VOT 及元音区间。

   关键点：人工校正是保证后续时间归一化与参数提取准确性的关键。

4. EGG 参数提取

   说明：用 Praat 脚本 praatdet 处理 EGG 信号，按 Howard (1995) 方法以 3:7 幅度阈值计算每个声门周期的开商（OQ）。

   关键点：阈值法计算 OQ 需先对 EGG 信号去噪和滤波；OQ 越高通常提示更气声化的发声。

5. 声学参数提取

   说明：用 Praat 与 PraatSauce 提取 VOT、爆发段重心频率（CoG）、f0、F1、F2、经声道校正的 H1*-A3* 以及倒谱峰突出度（CPP）。

   关键点：谐波幅度差须进行共振峰校正；CPP 用于衡量周期性/嗓音清晰度。

6. 时间归一化与统计建模

   说明：在 MATLAB 中对各参数轨迹进行时间归一化与平滑，再进行函数型主成分分析（FPCA），将 PC 得分以语域为固定效应、以被试为随机截距和随机斜率建立线性混合效应模型（R 包 lmerTest、emmeans、MuMIn）。

   关键点：FPCA 可捕捉整段轨迹的形状差异而非单点差异；随机斜率用于刻画个体间差异。

Larynograph

简介：I'm David Howard from york and we're company at the Dance center in London to look at B-boxing Let's look briefly at what the human instrument offers to the B-boxer because the human vocal instrument is the same for all of us We've all got what is basically a buzzer sounding something like this in our throat This is the vibrating vocal folds in the larynx so this can substitute for the larynx.

VOICED-UNVOICED CLASSIFICATION OF SPEECH USING AUTOCORRELATION MATRIX

简介：In this paper, a fast method for voiced-unvoiced classification of speech signals is introduced. The suggested method makes the V-UV decision, using signal energy, the peak-to-peak differerence of the autocorrelation function, number of zero crossings of the autocorrelation function and the unit delay autocorrelation coefficient all together.

Voice Timing in Two Parkinson’s Disease (PD) Patients following Subthalamic Nucleus Deep Brain Stimulation

简介：Speech and voice can have a variable response (Tripoliti et al, 2014). Subtypes of presentation have been proposed (Tsuboi et al, 2014). This study sought to examine the effects of STN-DBS on the temporal prosodic structure of voicing in the connected speech of two STN-DBS patients with contrasting presentations.

The Effect of Hearing Loss on the Vocal Features of Children

简介：The current study aimed to evaluate the effect of hearing loss on acoustic properties of voice through acoustic analysis of some vocal parameters in two groups of children with moderately severe or deep hearing loss, and normal children of the same age and gender.

REAL-TIME SPEECH PATTERN ELEMENT DISPLAYS FOR INTERACTIVE THERAPY

简介：New developments are presented and discussed for the interactive display and separate measurement of frication and nasality in addition to voice quality. Different clinical problems require appropriate combinations of speech pattern elements support different approaches and these are supported by appropriate combinations of speech pattern elements. Particular use has been made of the laryngograph signal so that the displays can be given a sense of immediacy and are highly accurate.

Pitch Determination from Bone Conducted Speech

简介：This paper explores the potential of pitch determination from bone conducted (BC) speech. Pitch determination from normal air conducted (AC) speech signal can not attain the expected level of accuracy for every voice and background conditions. In contrast, since BC speech is caused by the vibrations that have traveled through the vocal tract wall, it is robust against ambient conditions.

NON-INVASIVE MONITORING OF REFLEXIVE SWALLOWING

简介：These methods do not use radiation and have the potential to give more accurate timing information than can be derived from auditory/acoustic monitoring. Pilot data were obtained from the simultaneous use of four sensors: an ear-plug microphone of the type used successfully for the detection of otoacoustic emissions; a standard miniature electret microphone ordinarily used for speech recording; a miniature accelerometer of the type sometimes used for monitoring nasality....

Measuring voice in the clinic-Laryngograph Speech Studio Analyses

简介：In the present work the application of pitch perceptual criteria is described in the provision of an integrated framework for practical clinical assessment and therapy. Sustained sounds are shown to require quite different levels of sampling accuracy from those needed for ordinary connected speech. Radically useful results come from the application of these basic ideas to the representation and analysis of the pathological and the normal voice in case management and audit.

Laryngograph as a tool in diagnosis and therapy of voice disorders

简介：The electroglottography method is an instrumental analysis by the device called Laryngograph, which can be practically applied in the speech signal analysis for people with voice disorders issues. In this paper capabilities of this device are estimated. A very interesting fact is that visualization of the speech signal obtained with the use of Laryngograph device allows to detect the acoustically and phonetically most important features and present them in a graphical form.

SPEECHREADING OF WORDS AND SENTENCES BY NORMALLY HEARING AND HEARING IMPAIRED CHINESE SUBJECTS: THE ENHANCEMENT EFFECTS OF COMPOUND SPEECH PATTERNS

简介：Speech perception requires a receiver to make decisions both about trends and also about the language patterns of a speaker. Hearing people use the speaker’s speech signal as the direct sensory evidence. In the special case of visual speech perception, otherwise known as speechreading, this sensory evidence is derived from the visible articulation movements of speech. Unfortunately, many important articulation movements are invisible.

Closing and Opening Phase Variability in Dysphonia

简介：Four examples of the use of vocal fold contact phase measurement are discussed for unilateral paresis. In each case this aspect of voice quality is of greater importance than the physical measurement of loudness and pitch related parameters. For three of the cases electrostimulation has been used as a main part of the treatment.

ASPECTS OF VOICE QUALITY: DISPLAY, MEASUREMENT AND THERAPY

简介：In this workshop the physical measures of voice fundamental frequency and larynx contact quotient are explored in relation to the perception, analysis and treatment of aspects of voice quality in a speech and language therapy clinic. A fundamental principle is to analyse samples of continuous speech. The workshop will focus on clients with unilateral vocal fold paralysis.

Acoustical characteristics of vocal modes in singing

简介：This paper looks further into the characteristics of the voice modes in singing in order to test the model already provided. The conclusion is that the model is too simple to cover the full range. The work has also provided information on singers’ SPL and formants’ repositioning in dependence of pitch. Further work is recommended.

A Longitudinal Study Investigating Synchronization in a Singing Quintet

简介：Research suggests that synchronization between musicians during ensemble performances can be affected by the rhythmic or tonal complexity of the piece being performed and by group roles such as leader-follower relationships. Since previous studies have mostly been conducted within single performance sessions, developmental aspects of interpersonal synchronization in ensembles remain underinvestigated.
