Voice pitch

Why return to Paraiso Aphrodite was saying, her voice pitched low, as she glanced at Padorin striding by in doomed silence. We re not done here, Trix, I was hoping for your help. ... 

Fasting was necessary he insisted on weeks without meat. As well, Balsamo purchased and sacrificed nine live cockerels (a magical number, as everyone knew). They had to be black, white, and red three of each color in an expression of natural sympathy with the sparkling jewels of the hoard. He d also insisted they undertake ritual ablutions of the skin, followed by the application of special herbs, balms, unguents, and holy oils. All this he accompanied with chants in a high-pitched voice, like the Arabs when they prayed to Allah. 

An interesting effect caused by breathing hehum is the change in one s voice when speaking. Because hehum is less dense than air, the vocal cords produce sounds at a higher pitch than normal and the speaker sounds hke Donald Duck. 

In spoken English, neither monotones nor singsong voices are much admired. A skilled presenter modulates both the pitch and amplitude of his or her voice to help make the talk easier to listen to at the same time modulation helps accentuate or emphasize the most important material. 

QUALITATIVE COMMENTS (with 60 mg) There may well be time slowing. I noticed that the voices on the radio seemed to be of a deeper pitch. And with music there is a most easy flight of fantasy. I tried to keep a logical conversation going on the telephone, but I am pretty s ure there w ere problems. I found myself down sooner than I would have liked. ... 

Vaseghi and Rayner [Vaseghi and Rayner, 1990] propose an extended AR model to take account of signals with long-term correlation structure, such as voiced speech, singing or near-periodic music. The model, which is similar to the long term prediction schemes used in some speech coders, introduces extra predictor parameters around the pitch period T, so that equation 4.1 becomes ... 

Several techniques have been proposed for modifying the shape of the short-time spectrum so as to emphasize those portions deemed to be important for speech perception or to reduce the amplitude of those portions assumed to be noise. One approach is adaptive comb filtering[Lim et al., 1978], In this method, the fundamental frequency of voiced speech sounds is estimated, and a comb fdter is then constructed to pass signal power in the regions of the pitch harmonics and to suppress power in the valleys in between. Experimental results with normal-hearing subjects, however, have shown no significant improvement in intelligibility with this type of system [Perlmutter et al., 1977][Lim et al., 1978],... 

Some of the methods described above for pitch-scale modifications can also be used to control the location of the formants independently from the pitch. This can be used to make a voice more feminine or masculine (by altering the location of the formants), or to munchkinize a voice, an effect made popular by the movie Wizard of Oz . 

It was noted above that reliable pitch estimation is necessary for two-voice separation using the solution of Equation (9.75). Under a harmonic assumption, since the function in Equation (9.73) is nonlinear in the fundamental frequencies, a simple closed-form solution for pitch based on a least squares approach does not exist. Under certain...

Her Lord General held her close to his breast. Couldn t be finer. He watched the fires. He pressed her closer, a reproach. But you needn t have pitched in. It won t hurt to let Mogushestvo s armour roll over some of our trucks. The occasional success will tempt them further into the city. Still, his voice drifted over her, gentler than the heat, perhaps you could visit as many emplacements as possible, show the flag for me. ... 

Since the speed rises while your voice box remains the same size, the frequency v =. vSoUndA of the sound disturbances you make goes up. As the sound exits the bag, it creates a pressure wave in the air with the same characteristic frequency (if the sound wave inside is hitting the wall of the bag 1000 times per second, the bag will vibrate a little 1000 times per second), and hence you hear a higher pitched note.
