传统上，人们认为元音识别的主要信息是由发音音节准稳态部分的共振峰频率提供的。最近的研究提出了另一种观点，强调时间因素和动态（时变）频谱信息在确定元音感知方面的作用。9个元音/B/+元音+/B/音节。这些音节被电子方式以多种方式修改，以抑制频谱和持续时间信息的各种来源。两个元音感知实验，测试受试者的能力，以确定这些修改音节中的元音。这两个实验的结果揭示了在音节开始和偏移（在其适当的时间关系），允许元音识别的动态频谱信息的重要性。稳态光谱信息，剥夺其持续变化，是一个贫穷的基础上进行识别。结果构成了对元音感知的传统帐户的挑战，并指向动态信息的重要来源。
Traditionally, it has been held that the primary information for vowel indentification is provided by formant frequencies in the quasi-steady-state portion of the spoken syllable. Recent research has advanced an alternative view that emphasizes the role of temporal factors and dynamic (time-varying) spectral information in determining the perception of vowels. Nine vowels spoken in /b/+vowel+/b/ syllables were recorded. The syllables were modified electronically in several ways to suppress various sources of spectral and durational information. Two vowel-perception experiments were performed, testing subjects'' ability to identify vowels in these modified syllables. Results of both experiments revealed the importance of dynamic spectral information at syllable onset and offset (in its proper temporal relation) in permitting vowel identification. Steady-state spectral information, deprived of its durational variation, was a poor basis for identification. Results constitute a challenges to traditional accounts of vowel perception and point toward important sources of dynamic information.
