Abstract

The acoustic-phonetic characteristics of speech sounds are influenced by their linguistic position in the syllable or sentence. Because of acoustic-phonetic differences between different speech sounds, sounds vary in the amount of speaker information they contain. However, do spectral and durational differences between realizations of the same sound that were sampled from different linguistic positions also impact speaker information? We investigated speaker discrimination in [−focus] versus [+focus] word realizations. Twenty-one Dutch listeners participated in a same-different task, using stimuli varying in focus, vowel ([aː], [u]), and word context ([ɦ_k], [v_t]), spoken by 11 different speakers. Results showed that an effect of focus on speaker-dependent information was present, but limited to words containing [u]. Moreover, performance on [u] words was influenced by (interactions of) word context and trial type (same-vs. different-speaker). Context-dependent changes in a speech sound’s acoustics may affect its speaker-dependent information, albeit under specific conditions only.

作为元音实现功能的说话人歧视:焦点是否影响感知?

语音的声学语音特征受其在音节或句子中的语言位置的影响。由于不同语音之间的声学-语音差异，声音所包含的说话者信息量也不同。然而，从不同语言位置采样的同一声音的实现之间的频谱和持续时间差异是否也会影响说话者信息？我们调查了在[-focus]和[+focus]单词实现中的说话人歧视。21名荷兰听众参与了同一项不同的任务，使用了11名不同说话者所说的焦点、元音（[a]，[u]）和单词上下文（[ɦ_k]，[v_t]）不同的刺激。结果表明，焦点对说话人依赖信息的影响是存在的，但仅限于包含[u]的单词。此外，[u]单词的表现受到单词上下文和试语类型（同一说话者与不同说话者）的影响。语音声学中与上下文相关的变化可能会影响其与说话者相关的信息，尽管仅在特定条件下。

期刊介绍： The Dutch Journal of Applied Linguistics (DuJAL) focuses on promoting Dutch and Belgian work in applied linguistics among an international audience, but also welcomes contributions from other countries. It caters for both the academic society in the field and for language and communication experts working in other contexts, such as institutions involved in language policy, teacher training, curriculum development, assessment, and educational and communication consultancy. DuJAL is the digital continuation of Toegepaste Taalwetenschap in Artikelen, which had been the journal of Anéla, the Dutch Association of Applied Linguistics, for forty years. Like its predecessor, DuJAL wants to offer a platform to young researchers in applied linguistics, i.e. PhD candidates and MA students. In order to maintain a high standard all submissions are subjected to a ‘double blind’ review by at least one external reviewer and two of the editors. Contributions may be written in Dutch, English, German or French.
