You should also examine the " Transcription Exercises " pages for examples of transcribed speech. Phonemic Broad Transcription Phonemic transcription of speech does not attempt to record the extremely large number of idiosyncratic or contextual variations in pronunciation that occur in normal speech nor does it attempt to describe the individual variations that occur between speakers of a language or dialect.

A waveform is a two dimensional representation of a sound. The two dimensions in a waveform display are time and intensity. In this course and in most of the literature the vertical dimension is intensity and the horizontal dimension is time.

Waveforms are also known as time domain representations of sound as they are representations of changes in intensity over time. The intensity dimension actually displays sound pressure. Sound pressure is a measure of the tiny variations in air pressure that we are able to perceive as sound.

The greater the change in pressure, the louder the sound that we hear. Intensity and pressure are physical measurements of sound amplitude whilst loudness is a psychological or perceptual measurement. Sound intensity is often quoted in deciBels dB. The deciBels is a logarithmic scaling of sound pressure or intensity and approximates the way the ear and brain rescale sound amplitude.

In the waveforms that follow, the dB scale is not used. Intensity in these waveforms is a simple linear scaling of sound pressure. On the following pages various aspects of the speech waveform are discussed as they appear in the accompanying diagrams.

All of the diagrams represent the waveforms of the speech of a single male speaker of Australian English.

Speech Waveforms

For figures 1 to 4 the waveforms are 40 ms 0. Approximate phoneme boundaries are represented by thick vertical lines descending from the top boundary of each graphics box.

Waveforms and Source Characteristics There are two types of speech sound source: These two sound sources are modified by the frequency-selective filtering effects of different vocal tract shapes to produce the various sounds of speech.

The voiced source can be filtered "modulated" by the position of the tongue, lips and velum to produce all of the vowels as well as the various voiced consonants.

Similarly the aperiodic sources can be filtered to produce various unvoiced speech sounds, but the most important influence on the sound of such speech tokens is the position of the constriction that produces the turbulence. It is also possible for speech sounds to result from the mixture of both voiced and unvoiced sounds resulting in, for example, voiced fricatives.

In figure 1 one aperiodic and three periodic speech sounds are displayed for the purposes of contrasting the characteristics. No part of the waveform pattern of this sound is repeated at regular intervals, therefore the sound is said to be aperiodic.

The three vowel sounds, on the other hand are periodic. Both the gross shape of the waveform patterns and the majority of the fine detailed features are repeated at regular intervals. In the 40 ms slice shown in these diagrams these patterns repeat themselves about four times shown by the vertical lines.

This rate of repetition of the pattern is known as the fundamental frequency F0 of each of these speech segments. Each repetition or period of these patterns corresponds to one glottal cycle, or one cycle of vocal fold opening and closing in the larynx.
