Voice sound

So what brought you here I ask Mark, and my voice sounds loud and awkward from having too much behind it. 

Once you begin the essay writing stage, your journal will become an invaluable tool. It can help you use the right tone, neither too casual nor too formal, so that your essay sounds like you. While rereading it, make note of the words you use, and what your voice sounds like when you write. Also make note of the ideas and topics that hold your interest. Sometimes you may not be aware of your feelings about something until you take the time to explore them. Use your journal entries to search for possible essay material. 

Suddenly he thought of baby. What had happened to her Was she in heaven too He tried to ask the angel, but found he could not utter a word he was too weak and tired. The kind eyes watching him interpreted rightly the anxious look that crossed his face they were well accustomed to divining the unspoken troubles of worried little minds. The angel spoke and to Peter the voice sounded like heavenly music ... 

Glutamate also has a unique function in brain development. When you were very young, the neurons in your brain developed many connections, or synapses, with other neurons to optimize your ability to learn a great deal of information quickly, such as how to move your hands and feet, what your mother s voice sounds like, or what the color red looks like. But as you grew older (during adolescence), your brain became a bit...

Would your voice sound higher or lower in an 80% argon/20% oxygen mixture than in dry air (approximated as 80% nitrogen/20% oxygen) ... 

The larger one with the golden abdomen says, I hear them. Its voice sounds as if it is warped by some kind of artificial translation device. Again, it twists an electrical probe up its huge nostril. 

That s OK. I was nearby and I thought I d take another bok at your foot I ve brought an artibacterial dressing for it I tried to seem relaxed, but tiy voice sounded horribh lake to ir ears. 

Soon after, the shaman leading our circle asked everyone to sit up and we began our first round of song. Each member of the circle would in turn allow sound to come from him or her, which would reflect their experience. To me, my voice sounded like that of an old American Indian. I found it very soothing. 

Each of the computer s three voices normally plays independently. That is, each voice sounds the same, no matter what the other two are doing. If you make voice 1 beep and voice 2 growl, voice 1 always makes the same beep even if you change voice 2 s growl to a screech. For a simple analogy,... 

Breathing heliox also affects the voice. Helium is much less dense than nitrogen, so vocal cords vibrate faster in a heliox atmosphere. This raises the pitch of the diver s voice, and makes the diver s voice sound funny. Fortunately, this effect disappears when the diver surfaces and begins breathing air again. 

When people inhale helium gas and talk, their voices sound strange, as if it had been recorded and played back at a faster rate. Why do you think that happens ... 

Helium is less dense than air, so it is easier for our vocal cords to vibrate. Because of this, they vibrate faster, making our voices sound strange. 

I don t know whether it s my hormones, the Paxil, or the way this depression gets me down, she told me. I could see that she was trying to put a happy face on things, but beneath the surface cheerfulness, her voice sounded tired and discouraged. I just don t seem to have any energy anymore, and so of course, I don t exercise. I feel like a big whale just beached up on the shore somewhere. ... 

While you re rehearsing, you may want to watch your facial expressions in a mirror. Are you smiling and enthusiastic, or do you look somber and serious Observe how your facial expressions affect your tone. When you re smiling, your voice sounds friendly, pleasing, and warm when your expression is somber, your delivery may sound flat. Vary the tone of your voice and the tempo at which you speak. This will help create interest in what you say, especially if your interviewer s attention seems to be momentarily drifting away. 

Oh, no." His voice sounded indignant, a host whose hospitality has proved inadequate. "Do stay."... 

Tolton thought the voice sounded tetchy. "Thank you," he said, and started to wade forwards towards the cliff. A couple more directions, and he dived under the surface. 

Another important set of periodic sounds that have harmonic spectra are the voiced sounds of speech. Figure 6.2 shows the spectrum of the voiced vowel sound ahh (as in father), and Figure 6.3 shows the spectrum of the voiced vowel sound eee (as in beet). 

So the speed of sound is faster, but why does that make your voice sound weird The tone is actually identical what s different is the timbre. Specifically, the lower frequencies of your voice have less power, so your voice sounds squeaky—like a duck. 

Fermi, superb experimentalist that he was, contributed valuably to the program of experimental studies, defining with clarity problems that needed to be examined. For him the war work was duty, however, and the eager conviction he found on the Hill puzzled him. After he had sat in on one of his first conferences here, Oppenheimer recalls, he turned to me and said, I believe your people actually want to make a bomb. I remember his voice sounded surprised. ... 

The diversity of sound from the source and output are fiirther enriched by the operation of the vocal tract. The vocal tract is collective term given to the pharynx, the oral cavity and the nasal cavity. These articulators can be used to modify the basic sound source and in doing so create a wider variety of sounds than would be possible by the source alone. Recall that all voiced sounds from the glottis comprise a fundamental frequency and its harmonics. The vocal tract functions by modifying these harmonics which has the effect of changing the timbre of the sound. That is, it does not alter the fundamental frequency, or even the frequency of the harmonics, but it does alter the relative strengths of the harmonics. 

Figures 12.4 and 12.5 show some typical power spectra for voiced and unvoiced speech. For the voiced sounds, we can clearly see the harmonics as the series of spikes. They are evenly spaced, and the fundamental frequency of the the source, the glottis, can be estimated by taking the reciprocal of the distance between the harmonics. In addition, the formants can clearly be seen as the more general peaks in the spectrum. The general shape of the spectrum ignoring the harmonics is often referred to as the envelope.

Given the durations, we ean ealculate the source signal for the utterance. We use an impulse source for sonorant phones, a noise source for unvoiced consonants, and a combined impulse and noise souree for voiced obstruents. The source characteristies are switched at phone boundaries. For voiced sounds, the impulse sequence is created by plaeing impulses at a separation distanee determined by 1 /FO at that point. Finally we feed the souree signal into the filter coefficients to generate the final speech waveform for the sentence. 

An impulse train is used to generate voiced sounds and a noise source obstruent sounds. These are then passed through the filters to produce speech. 

What then makes one voice sound more natural than another Again, this is a question that we are not in a position to answer fully, but we can provide a sketch of the factors involved. Firstly, any system that produces obviously non-human artefacts in the speech will readily be judged as unnatural. It is all too easy to generate speech with pops, clicks, buzzes and an endless variety of other mechanical sounds. Even speech that is devoid of any of these error types of sounds can readily sound unnatural. While speech exhibits considerable variability in the realisation of a particular phoneme, this is controlled by...
