共振峰

Formants are frequency maxima in the spectrum of the speech signal.

共振峰是语音频谱音频率最大值。

Conclution The discriminating value of formants within different frequency ranges was no significant difference due to the influence of the stability of formants.

结论不同频率共振峰在话者识别中的区别能力无显著差异。

Postoperative findings included improvement of harmonic waves and formants with decrease of noise.

喉显微手术后语图可表现谐波及共振峰规律及连续性逐渐恢复，噪声成分逐步减少。

The technique spectrum-level-normalization was used to balance the amplitude difference between formants.

其中，频谱正规化(Spectrum-Level-Normalization)用以平衡不同共振峰的高度差异。

Objectie:To obsere the changes of fundamental frequency and formants of owel in cochlear implant pre-lingual children of different age and to proide the basis and direction for post-operatie rehabilitation.

目的观察不同年龄的语前聋人工耳蜗置入的儿童在置入人工耳蜗后，其元音基频和共振峰的变化规律，为术后语言康复工作提供指导和依据。

The sonogram in benign hyperplastic vocal fold lesions showed irregularity,breakage or lack of harmonic wavesand formants,and increase of noise.

结果 声带良性增生性病变者语图表现谐波及共振峰不规则、断裂甚至缺失，噪声成分增加。

Methods Measurement of voice signal was made using micro-computer and acoustic software during sustained phonation of vowel /a/ in 50 healthy subjects and 50 patients with benign vocal fold lesions.The harmonic waves,formants and noise of the sonogram were analysed. Results There were significant differences of acoustic characteristics between normal and pathologic groups.

采用&电子计算机声学测试系统&对50例正常成人及50例声带良性增生性疾病患者发持续元音/a/时的声音信号进行检测，分析元音语图谐波、共振峰及噪声成分特征及变化规律。

The acoustic features were extracted from mandarin utterances under neutral, happy, angry and sad status. The features consist of pitch, the first three formants frequencies, short-term energy, duration, speaking rate and brightness.

分析在平静和生气、欢快、悲伤等情绪下，汉语语音的基频、短时能量、时长、语速、共振峰和明亮度的变化规律。

The measured indexes of vowel, which were input into CSL4400, were duration, pitch, the first three formants (F1, F2, F3) and energy. The acoustic features of the vowel of each group were compared by SPSS software with Paired t test.

将被检音输入计算机语音工作站CSL400，测量其元音的音长、基频、前3个共振峰和音强，采用SPSS11.5统计软件对所得数据进行配对t检验。

The acousic parameters and spectrographic characteristics (harmonic waves,formants and noise) were analyzed.The resubs obtained by acoustic technique were compared with those of perceptual evaluation.Results The acoustic parameters were significantly increased in all patients with laryngeal diseases.

Speech Science for Windows软件对78例正常成人及98例喉病患者元音信号进行检测，对其主要声学参数及声谱图特征(谐波、共振峰、噪声成分等)进行分析，并与主观听觉评价结果进行了比较。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
