实验方法

研究方向：发音运动的超声舌位成像、超声与电磁发音仪的同步配准、舌运动学的动力学建模、卷舌音的发音实现与语音变化、会话轮替中的发音准备、唇腭裂患者正颌手术后的言语结局

高速超声舌位成像与电磁发音仪（EMA）同步采集及舌运动动力学参数估计

方法说明：使用 Telemed MicrUs 便携式超声仪（64 阵元、20 mm 半径、2 MHz 微凸探头，约 81 Hz 帧率）配合 Articulate Assistant Advanced（AAA）软件与 Carstens AG501 电磁发音仪同步采集英语元音发音数据。通过超声同步脉冲与 EMA 的 TTL 脉冲在 AAA 中实现帧级时间对齐，用 UltraFit 非金属头架固定探头并以 EMA 传感器追踪探头位移与旋转；随后用 DeepLabCut 追踪超声图像中的舌部解剖标志点，拟合线性谐振子模型，比较超声与 EMA 两种模态得到的动力学参数是否一致。

实验仪器：MicrUs 便携式超声扫描仪 MicrUs EXT-1H；64 阵元微凸超声探头 MC4-2R20S-3；AG501 电磁发音仪 AG501；Pulse Stretch 脉冲展宽单元；UltraFit 超声头架 UltraFit；Opus 55 全向头戴麦克风 Opus 55；m101 话筒前置放大器 m101；DAQ-2213 模数转换器 DAQ-2213；iO2 音频接口 iO2

实验步骤

  1. 硬件连接与同步设置

    说明：将 Telemed MicrUs 超声仪、Articulate Instruments 脉冲展宽单元、AG501 EMA 和音频接口连接至 AAA 软件，EMA 的 TTL 同步脉冲作为额外音轨录入超声电脑。

    关键点：超声纳秒级同步脉冲需经 Pulse Stretch 单元转换为毫秒级脉冲；EMA 脉冲在录音开始前 80 ms 拉低、每 4 ms 发送一次

  2. 探头固定与被试准备

    说明：使用全塑料/非金属织物的 UltraFit 头架固定超声探头于下颌，被试贴附标准 EMA 传感器（舌尖、舌中、舌背、上下唇、下齿）及参考传感器（乳突、鼻梁、上切牙）。

    关键点：头架必须非金属，否则会显著降低 EMA 位置估计精度；超声主机需放置在 EMA 磁场中心后方约 60 cm 处

  3. 语料录制

    说明：6 名英格兰北部英语女性发音人朗读 'she says X'、'she says X dearly/eagerly' 或 'She said X (eagerly)' 载体句中的 bV/bVd 词，每块 58 个短语重复 4–5 次。

    关键点：超声帧率约 81 Hz（80–100 Hz），EMA 1250 Hz；探头被重新定位的块须剔除

  4. 校准与探头运动验证

    说明：用 circal 装置进行有/无超声设备两种条件下各 3 次 EMA 校准比较 Δz 与 σz；用 3D 打印三角形固定 3 个 EMA 传感器追踪探头的 x/y/z 位移与 roll/pitch/yaw 旋转。

    关键点：σz 应低于 0.25 mm；探头平移与旋转需在 2–4 mm、5° 以内的 HOCUS 容差范围内

  5. 数据处理与动力学建模

    说明：用 Montreal Forced Aligner 做强制对齐；用 AAA 内置 DeepLabCut 舌模型追踪 11 个舌部标志点及短腱、舌骨点，旋转至咬合平面；EMA 降采样至超声帧率，用 5 阶离散余弦变换平滑；以约束最小二乘拟合线性谐振子并用贝叶斯层级回归比较两模态参数。

    关键点：超声信号噪声大，须平滑处理；EMA 传感器在超声图像中不可见，两模态位置点只能近似对应

摘要 · 中文整理：言语控制可以建模为一个动力学系统，其中发音器官被驱动趋向目标位置。此类模型通常用电磁发音仪（EMA）等肉点数据来检验，但近年的方法学进展使超声成像成为一种颇具前景的替代手段。本文评估能否从超声舌部运动学中可靠地估计线性谐振子模型的参数，并与同步记录的 EMA 数据所估参数进行比较。结果发现超声与 EMA 给出的动力学参数具有可比性，同时对下颌短肌腱的追踪也能充分刻画下颌运动。这支持使用超声运动学来评估动力学发音模型。

原文摘要：The control of speech can be modelled as a dynamical system in which articulators are driven toward target positions. These models are typically evaluated using fleshpoint data, such as electromagnetic articulography (EMA), but recent methodological advances make ultrasound imaging a promising alternative. We evaluate whether the parameters of a linear harmonic oscillator can be reliably estimated from ultrasound tongue kinematics and compare these with parameters estimated from simultaneously-recorded EMA data. We find that ultrasound and EMA yield comparable dynamical parameters, while mandibular short tendon tracking also adequately captures jaw motion. This supports using ultrasound kinematics to evaluate dynamical articulatory models.

关键词：言语运动控制、动力学模型、超声舌部成像、电磁发音仪、线性谐振子

研究目标：验证能否从超声舌位成像的运动学数据中可靠估计线性谐振子（任务动力学）模型的参数，从而替代侵入性更强、便携性更差的 EMA 数据。

主要结论：线性任务动力学模型可高精度拟合超声运动学数据（R² ≥ 0.90），超声与 EMA 得到的刚度与阻尼参数变异程度相当，目标参数的系统差异与超声追踪的已知特性一致；下颌短腱追踪能充分捕捉下颌运动。

创新点：首次用同步采集的超声与 EMA 数据系统比较动力学模型参数估计；将 DeepLabCut 舌部标志点追踪与谐振子模型拟合、贝叶斯层级回归相结合；展示了超声短腱追踪作为下颌运动指标的可行性。

后续建议：扩展到辅音及更复杂的非线性或非自治动力学模型；引入更多发音人、语言与临床人群以检验方法的普适性；改进超声与 EMA 空间点的对应关系以减少目标参数的系统偏差；评估不同平滑方法对参数估计的影响

摘要 · 中文整理：目的：本研究通过手术前后的超声成像、气动评估与发音分析，评估正颌手术对已修复唇腭裂的 III 类患者言语的影响，以了解手术如何影响发音、腭咽功能与鼻音过重。材料与方法：对 5 名已修复唇腭裂的 III 类患者、5 名无唇腭裂的 III 类患者和 5 名 I 类对照在手术前后进行超声成像以观察舌手势。用超声计算舌背偏移指数与舌约束位置指数，用压力-流量评估测量腭咽闭合不全指标，并与言语语言病理学家的定性感知评分比较。用线性混合效应模型检验各辅音的舌背偏移指数与舌约束位置指数术后是否显著变化。压力-流量测量采用 PERCI-SARS 估计言语中的腭咽间隙大小。结果：唇腭裂患者 /k/ 在前、后元音前的舌背偏移指数显著更低。舌约束位置指数显示唇腭裂患者始终低于对照与 III 类患者，且所有辅音均存在个体间与个体内变异。两名唇腭裂患者的压力-流量数据显示术后存在腭咽闭合不全与鼻音改变的证据。结论：与对照相比，唇腭裂患者的舌背偏移指数与舌约束位置指数更低，提示舌位更靠前。这些指数可用于理解舌形与运动变化，有助于阐明颌骨手术对言语的功能性影响。舌背偏移指数与压力-流量数据表明唇腭裂患者正颌手术后代偿性发音与腭咽闭合不全增加，影响言语。

原文摘要：Objectives: This study evaluated the effects of orthognathic surgery on speech of Class III patients with repaired cleft lip and palate through ultrasound imaging, aerodynamic assessment and articulatory analyses before and after surgery to evaluate how surgery impacts articulation, velopharyngeal function and hypernasality. Materials and Methods: Tongue gestures of five Class III patients with repaired cleft lip and palate, five Class III patients without cleft lip and palate and five Class I controls were visualised through ultrasound imaging pre- and post-surgery. Tongue Dorsum Excursion Index and Tongue Constraint Position Index were calculated using ultrasound, and velopharyngeal insufficiency indices were measured using pressure flow assessment and compared with qualitative-perceptual ratings by Speech-Language Pathologists. Linear mixed-effects models were used to test for significant post-operative changes in Dorsum Excursion Index and Tongue Constraint Position Index among consonants. Pressure flow measures are expected to estimate velopharyngeal gap size during speech using PERCI-SARS. Results: Patients with cleft lip and palate had significantly lower Dorsum Excursion Index for /k/ before front and back vowels. Tongue Constraint Position Index revealed consistently lower values for patients with cleft lip and palate than controls and Class III patients, with inter- and intra-speaker variation for all consonants. Pressure flow data of two patients with cleft lip and palate showed evidence of velopharyngeal insufficiency and altered nasality post-surgery. Conclusion: Patients with cleft lip and palate present with lower Dorsum Excursion Index and Tongue Constraint Position Index when compared to controls, suggesting more anterior tongue positioning. These indices can be used to understand tongue shape and movement changes, potentially elucidating functional effects of jaw surgery on speech. Dorsum Excursion Index and pressure flow data indicate increased compensatory articulations and velopharyngeal insufficiency after orthognathic surgery for patients with cleft lip and palate, impacting speech.

The articulation of Scottish Gaelic plain and palatalized consonants

简介：Scottish Gaelic exhibits a rich system of consonant mutation, which is mostly governed by its morphology. For instance, the initial consonant [p] of a SG word bàta ‘boat’ changes to [v] when the word undergoes morphological inflection – e.g., a bhàta ‘his boat’, in which bh is pronounced as [v]. Although consonant mutation in SG is well documented (Macaulay, Ladefoged et al. , Gillies, Stewart ), there is only one experimental, quantitative study on this to date (Archangeli et al. (2011)).

In most cases, phonetic transcription is deemed to be gold standard in diagnosing speech sound disorders associated with cleft palate (Sell 2005). Due to the heterogeneity and complexity of CP, atypical and compensatory articulations may not be identified through phonetic transcription alone.

Very High Frame Rate Ultrasound Tongue Imaging

简介：This paper examines the trade-off between temporal and spatial resolution in ultrasound tongue images at fast frame rates. The fastest lingual speech movements are investigated using a variety of echo pulse densities. Benefits and drawbacks of using higher frame rates are considered. Faster frame rates reduce distortion of the shape of the tongue during highly dynamic segments but it becomes increasingly difficult to discern the detail of that shape.

F1/F2 TARGETS FOR FINNISH SINGLE VS. DOUBLE VOWELS

简介：This paper explores the reason why Finnish single (short) vowels tend to occupy less peripheral positions in the F1/F2 vowel space compared to their double (long) counterparts. The results of two production studies suggest that the less extreme vowel quality of single vowels is best described as arising from undershoot of articulatory/acoustic targets due to their short durations, assuming single, context-free targets for phonemes.

A recording and analysis protocol is described which allows for correction for probe movement or rejection of data where correction is not possible. Results indicate a slight superior and posterior displacement of the tongue root in supine posture, consistent with a shift in the support structure of the tongue.
