Description: 語音信號是基於時間軸上的一維數位信號，在這裏主要是對語音信號進行頻域上的分析。在信號分析中，頻域往往包含了更多的資訊。對於頻域來說，大概有8種波形可以讓我們分析：矩形方波，鋸齒波，梯形波，臨界阻尼指數脈衝波形，三角波，餘旋波，余旋平方波，高斯波。對於各種波形，我們都可以用一種方法來分析，就是傅立葉變換：將時域的波形轉化到頻域來分析。-Voice signal is based on the timeline of one-dimensional digital signal, where mainly the speech signal in frequency domain analysis. In signal analysis, frequency domain often contains more information. For the frequency domain for about 8 allows us to analyze waveforms: rectangular square wave, sawtooth, trapezoidal wave, the critical damping index pulse, triangle wave, I spin wave, I spin square wave, Gaussian. For all waveforms, we can analyze in a way that is Fourier transform: the transformation of time domain waveform into the frequency domain to analyze Platform: |

Description: Splice out the voiced plosive “b” in theword “be” and synthesize aword with an increase in the
voice onset time of the “b.” What is the perceptual effect? Is it possible to transform the voiced
plosive “b” to the unvoiced plosive “p” with this change in the voiced onset time? Consider
attributes such as vocal cord vibration and aspiration. (In splicing, display the waveform and
spectrogram of the word “be” and use the MATLAB function ginput.m.) Optional: If your
transformed sound does not sound like a “p” then, again considering vocal cord vibration and
aspiration, make a more accurate transformation. Platform: |

Description: 本闹钟系统共有五个按键，各有不同的功能，每个按键按下都会发出提示音。前三个按键组合使用用于调节时钟第一次响铃和第二次闹铃的时间。第四个按键控制显示十五种心形流水灯效果，第五个按键按下时单片机先检测温度，然后控制语音芯片播报当前室温。当系统达到闹铃所设的时间时会有闹铃声音，只有通过手枪（经过玩具手枪改造可以发出指定编码的红外线）射出红外线才能停止，而且手枪瞄准位置误差太大时，闹铃将接收不到继续响铃，所以人必须稍微清醒并且瞄准目标才能关闭闹铃。当平时没有闹铃时若用手枪打闹钟，闹钟就会播放当前温度。另外平时时只让时钟数码管亮，心形流水灯不亮。-The alarm system consists of five buttons, each with different functions, each key press will beep sounds.

When the system reaches the alarm will be set by the time the alarm sounds, only through the gun (a toy gun transformation can be issued through the specified encoding infrared) emitted infrared to stop, and the pistol aimed at the position error is too large, the alarm will not received to continue ringing, so people need a little sober and aim at the target to turn off the alarm. When the alarm if not usually hit with a pistol Alarm Clock will play the current temperature. Also usually only when the digital clock so that bright, heart-shaped water does not Platform: |
