摘要 · 中文整理：在语音处理领域，发音-声学映射（AAM）方法可以将超声舌位成像（UTI）作为输入。本研究比较了原始扫描线表示与经处理的扇形UTI图像作为残差网络输入用于AAM的效果。结果发现两种表示之间无显著差异，并确定原始扫描线输入的最优像素尺寸为64×43、扇形图像的最优尺寸为64×64，因此无需使用完整的64×842像素原始扫描线数据。更小的图像可以构建更小的网络，有利于静默语音接口应用，可帮助言语障碍者交流，并适用于军事场景或极端噪声环境。
原文摘要：Within speech processing, articulatory-to-acoustic mapping (AAM) methods can apply ultrasound tongue imaging (UTI) as an input. In this study we compared the raw scanline representation with the wedge-shaped processed UTI as the input for the residual network applied for AAM. We found no significant differences between the two representations, and identified the optimal pixel size to be 64 × 43 in the case of the raw scanline input, and 64 × 64 when transformed to a wedge. Therefore, it is not necessary to use the full original 64 × 842 pixels raw scanline. Smaller images allow the construction of smaller networks, which can be advantageous for silent speech interface applications, being helpful for the communication of the speaking-impaired, in military applications, or in extremely noisy conditions.
关键词：语音处理、超声成像、深度学习
研究目标：确定超声舌位图像作为深度残差网络发音-声学映射输入时的最优表示形式（原始扫描线还是扇形图像）与最优分辨率，以在不损失合成质量的前提下减小网络规模。
主要结论：原始扫描线与扇形图像两种表示在AAM性能上无显著差异；原始扫描线最优尺寸为64×43，扇形图像最优尺寸为64×64，无需使用完整的64×842原始数据，小尺寸输入可支持更紧凑的网络以用于静默语音接口。
创新点：首次系统比较了原始扫描线与扇形超声舌位图像在残差网络AAM中的效果，并给出了输入分辨率的最优选择依据。
后续建议：扩展到多说话人数据以验证结论的跨说话人泛化能力；引入时序建模（如3D卷积或Transformer）利用相邻帧信息；结合唇部视频等多模态输入提升合成质量；探索神经声码器以替代传统声码器提高听感自然度

Factors affecting the articulatory and acoustic characteristics of vowels in clear speech
简介：The purpose of this study was twofold: to examine the specific articulatory processes of clear speech for individual vowels using ultrasound, and to provide a more comprehensive investigation of the factors affecting the production of clear speech. In particular, we investigated how the type of listener (hard of hearing vs. normal hearing) and the lexical properties of words (frequency and phonological neighborhood density) interact.

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)).

Traditionally, it is said that light [l] occurs in onsets (e.g. light) and dark [l+] in codas (e.g. dull; Giegerich 1992; Halle & Mohanan 1985), but many studies report varying distributions of light and dark /l/ in different morphosyntactic environments.

Segment Constants and Speaker Constants in English Coronal Obstruents
简介：This paper examines the articulation of the coronal obstruents /t, s, θ, tʃ, ʃ/. Previous studies have found that there is variation in the production of coronals (Dart, 1991; Delattre & Freeman, 1968; Reichard et al., 2012; Stone et al., 2012). These studies examined single segments (/r/, /s/). We compared segments with different places and manners of articulation, with the aim of isolating the articulatory correlates of the various coronal places in English.

Can seeing help you hear? Acoustic vs. Ultrasound information in the diagnosis of speech sound disorders associated with cleft palate
简介：Many studies investigating speech characteristics in cleft palate (CP) have been based on perceptual analysis. 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.

While most children go on to attain age-appropriate speech production, an estimated 30% of English-speaking children with a history of speech sound disorder continue to misproduce rhotic sounds at 9 years of age, and 9% still show these errors from 1218 years and beyond (Lewis & Shriberg, 1994).

简介：This presentation reports two projects employing ultrasound imaging to augment conversational speech corpora of French from Gatineau, Quebec, and English from Raleigh, North Carolina. Targeted articulatory data are collected in order to study phonetically-motivated sound changes in progress. While phonetically-motivated change from below is a fundamental concept in contemporary approaches to phonology and variation, empirical data is sparse (Cedergren, 1973; Trudgill, 1974; Labov, 2001)。

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.
