1·MFCC parameters is main describes the spectrum envelope features, which is used to state the vacal track characterizatics, while ignoring the impact of pitch frequency.

MFCC参数主要描述了表征声道特性的谱包络特征，而忽略了基音频率对它的影响。

2·The improved method based on fuzzy entropy, which analyzed and distilled the weight of speech duration, average magnitudes, pitch frequency, formants and Mel-frequency cesptral coefficients.

分析了发音持续时间、平均振幅、基音频率，第一共振峰和Mel频率倒谱参数，并基于模糊熵理论提取了各参数的权重。

3·If a singer hits a pitch that matches the frequency of one glass, the glass might absorb so much acoustic energy that it will shatter; the other glasses remain unaffected.

如果一个歌手唱到一定的音高，那么与之频率相对应的酒杯就会共振，有时杯子吸收了太多的能量而碎掉，但是其他的杯子却安然无恙。

4·A vibration that has a higher or lower frequency than a sound, he found, tends to skew pitch perception up or down.

频率超过或低于声音频率的震动会分别引起音高知觉的上调和下调。

5·Auditory fusion frequency (AFF) of impulse sound and paired pitch in 80 workers exposed to noise and 60 non exposed ones were measured to study the relationship between AFF and auditory fatigue.

为探讨闪声融合频率与听觉疲劳的关系，测量了80名接触噪声工人和60名非接触噪声人员的脉冲声和双音调闪声融合频率。

6·The weak intonation is shown in the following features: low fundamental frequency, narrow pitch range, and the rising of boundary tone.

祈使句语气的弱化通常体现在以下几个方面：降低基频、缩小基频范围、以及抬高边界调。

7·This too causes the waveform to lose energy as well as, in turn, frequency and pitch, resulting in you hearing a distorted, lower tone than what people hear directly from out of your mouth.

这同样使声波能量降低，随之带来音调和音高的降低，使得我们自己听到的声音远低于周围人直接听到的声音。

8·The electromagnetic force decays rapidly in the molten steel, and its decaying speed is related to the current frequency and polar pitch of the stirrer.

在电磁搅拌作用下，电磁力的大小随钢液液池宽度的增加呈指数衰减趋势，其衰减速率与电流频率和搅拌器极距有关。

9·An improved pitch control scheme is presented by introducing a frequency deviation signal into the control system.

提出了一种改进的桨距角控制方案——将系统频率偏差信号引入桨距角控制系统。

10·Sound example 5: Yankee Doodle played on strings tuned to the same pitch (transverse frequency) but with different longitudinal mode frequencies (two versions in different keys).

健全例如5：“扬基歌”上播放字符串调整同一球场（横向频率），但不同的纵模频率（两个版本在不同的键）。
