Numerous updates include MRI images of vocal tracts. In addition, the thoroughly revised companion website includes interactive exercises, instant spectr. A complete basic course in English phonetics and phonology which combines academic material with practical exercises, both written and recorded.

Since the publication of the first edition in , this course has established itself as the most practical, comprehensive text in the field and become widely used in many parts of the world in universities and other institutions of higher education. It is used by both native and non-native speakers alike, and is suitable for those training to teach English as well as those studying the language at an advanced level.

This new edition takes into account recent developments in the teaching of phonology. It includes updated references, fuller coverage of intonation, and a new chapter on different varieties of English with illustrative recorded material. English Phonetics and Phonology bridges the gap between simple pronunciation handbooks and technical phonetics and phonology textbooks. It presents the basic factual material and crucial theoretical issues in a practical and readable way.

At the end of each chapter there are notes giving information on further reading, discussion of the more challenging issues, written exercises and, where appropriate, suggestions for teachers.

In addition the audio CDs include recorded exercises for every chapter which are particularly helpful for non-native speakers. A full answer key is available at the back of the book. Additional exercises and other supporting material are available online. This is a fully integrated course book aimed at universi-ty students of English in the German-speaking region. It presents a staged and clearly developed introducti on to the theory of pronunciati on combined with a wealth of transcripti on exercises and an accompanying CD.

The book requires no prior knowledge of linguisti cs. From the outset, it explains key concepts in easy-to-understand language, highlights key terms in the text for easy re-view, and gives translati ons of many of the terms into German. Additi onally, a glossary provides students with a handy quick reference. The transcripti on exercises gui-de students from exploratory tasks to basic transcripti on to the more demanding transcripti on of natural dialogue, and all exercises are supplied with annotated soluti ons.

The book is carefully divided into lessons and exercises which can be managed in 12 two-hour classes, leaving enough ti me for review and examinati on in a university term of 14 weeks or more. Phonology: Critical Concepts, the first such anthology to appear in thirty years and the largest ever published, brings together over a hundred previously published book chapters and articles from professional journals.

These have been chosen for their importance in the exploration of theoretical questions, with some preference for essays that are not easily accessible. Divided into sections, each part is preceded by a brief introduction which aims to point out the problems addressed by the various articles and show their relations to one another.

This superb introduction to phonetics, with an accompanying CD, is perfect for anyone who wants to learn about the sounds of language. Phonology: The variants of the phonemes that occur in detailed phonetic transcriptions are known as allophones.

The term broad transcription is often used to designate a transcription that uses a simple set of symbols. Conversely, a narrow transcription is one that shows more phonetic detail, either just by using more specific symbols or by also representing some allophonic differences. The use of diacritics, small marks that can be added to a symbol to modify its value, is a means of increasing precision.

A transcription that shows the allophones so detailed that it shows all the rule-governed alternations among the sounds is called a completely systematic phonetic transcription. In practice, it is difficult to make a transcription so narrow that it shows every detail of the sounds involved. When writing down an unknown language or when transcribing a child or a patient not seen previously, one does not know what rules will apply. In these circumstances, the symbols indicate only the phonetic value of the sounds.

This kind of transcription is called an impressionistic transcription. The Transcription of Vowels: The transcription of the contrasting vowels the vowel phonemes in English is more difficult than the transcription of consonants for two reasons.

First, accents of English differ more in their use of vowels than in their use of consonants. Second, authorities differ widely in their views of what constitutes an appropriate description of vowels. Most speakers of British English distinguish these words by using different dipthongs — movements from one vowel to another within a single syllable.

A good way is to find sets of words that rhyme. A set of words, each of which differs from all the others by only one sound, is called a minimal set.

For example, high and sigh will be a minimal set. Given below is IPA Chart with various symbols. Acoustic Phonetics The way in which we hear a sound depends on its acoustic structure.

Linguists and speech pathologists need to explain why certain sounds are confused with one another. They can also give better descriptions of some sounds such as vowels by describing their acoustic structure rather than by describing the articulatory movements involved. A knowledge of acoustic phonetics is also helpful for understanding how computers synthesize speech and how speech recognition works. If we want to analyze speech we have to work from a recording. We can get more information than is available from merely listening to a recording by making acoustic analyses of the sounds.

We can hear that sounds with the same length can differ from one another in three ways. They can be the same or different in 1 pitch, 2 loudness, and 3 quality. Sound Waves: Sound consists of small variations in air pressure that occurs very rapidly one after another.

In the case of voiced sounds, the vibrating vocal folds chop up the stream of lung air so that pluses of relatively high pressure alternate with moments of lower pressure. In fricative sounds, the airstream is forced through a narrow gap so that it becomes turbulent, with irregularity occurring peaks of pressure. The same principles apply in the production of other types of sounds. Variations in air pressure in the form of sound waves move through the air somewhat like ripples on a pond.

When they reach the ear of a listener, they cause the eardrum to vibrate. A graph of the sound wave is very similar to a grapg of the movements of the eardrum. The waveforms of speech sounds can be readily observed on a computer. Pitch and Frequency: The pitch of a sound depends on the rate of vibration of the vocal folds. In a sound with a high pitch, there is a higher frequency of vibration than in a sound with a low pitch. Because each opening and closing of the vocal folds causes a peak of air pressure in the sound wave, we can estimate the pitch of a sound by observing the rate of occurrence of the peaks in the wave-form.

To be more exact, we can measure the frequency of the sound in this way. Frequency is the technical term for an acoustic property of the sound- namely, the number of complete repetitions cycles of variations in air pressure occurring in a second.

If the vocal folds make complete opening and closing movements in a second, we say that the frequency of the sound is Hz. The pitch of the sound is that auditory property that enables a listener to place it on a scale going from low to high, without considering its acoustic properties.

In practice, when a speech sound goes up in frequency, it also goes up in pitch. It is possible to determine the frequency of a sound by counting the peaks of air pressure in a record of its waveform. Computer systems will provide graphical displays corresponding to the pitch. Voiceless sounds have no vocal fold pulses and therefore no pitch. For male voice, the frequency of the vocal fold vibrations in speech may be between 80 to Hz. The prominent frequencies in voiceless sounds are usually above 2, Hz.

Loudness and Intensity: In general, the loudness of a sound depends on the size of the variations in air pressure that occur. The intensity is proportional to the average size, or amplitude, of the variations in air pressure. It is usually measured in decibels abbreviated as dB relative to the amplitude of some other sounds. Technically, to get to the dB difference one has to compare the power ratio, where the power is defined as the square of the mean amplitude the mean variation in air pressure.

The human ear can hear perhaps tolerate would be a better word a range of about dB, although if you persist in listening to sounds to dB above the quietest sounds you can hear you will soon go deaf.

When one sound has an intensity 5 dB greater than another, then it is approximately twice as loud. Acoustic Measurements: Within the range of pitches used by both make and female voices, a change in frequency is directly to a change in pitch. The relation between pitch and frequency has been derived experimentally and used to form the Bark scale.

Equal distances along the Bark scale correspond to equal changes in pitch. The mathematical relation between Hz and Bark is fairly complex. When dealing simply with the pitch of the voice, a straightforward linear plot of frequency is sufficient. The relation between acoustic intensity and loudness is also nonlinear, but fortunately only slightly so. For all practical purposes we can consider differences in loudness to be simply related to differences in intensity, reported in dB.

Each increase of 5 dB corresponds to a doubling of the perceived loudness. Acoustic records are useful for studying various kinds of phonetic problems. Records of the waveform and the intensity provide a good way of studying variations in length.

Acoustic Analysis of Vowels: Is has been described how differences in pitch and loudness can be recorded. Now we must consider the differences in quality. A set of vowel sounds provides a suitable starting point, since vowels can all be said on the same pitch and with the same loudness. The quality of a sound such as a vowel depends on its overtone structure. Putting this way, we can say that a vowel sound contains a number of different pitches simultaneously.

There is a pitch at which it is actually spoken and there are the various overtone pitches that give it its distinctive quality. We distinguish one vowel from another by the differences in the overtones. Saying the vowels in usual rate, whispering, whistling, using a creaky-voice, making glottal stops can be used to distinguish vowels. Vowels are largely distinguished by two characteristic pitches associated with their overtones.

The other goes up for the first four vowels and then down for the nest four. These characteristic overtones are called the formants of the vowels, the lower of the two being called the first formants, and the higher the second formant.

There is another characteristic overtone, the third formant, which is also present, but there is no simple way of demonstrating its pitch.

The formants that characterize different vowels are the result of the different shapes of the vocal tract. Any body of air, such as that in the vocal tract or that in a bottle, will vibrate in a way that depends on its size and shape.

Smaller bodies of air, like smaller piano strings or smaller organ pipes, produce higher pitches. In the case of vowel sounds, the vocal tract has a complex shape so that the different bodies of air produce a number of overtones.

A vowel has its own characteristic auditory quality, which is the result of the specific variations in air pressure due to its vocal tract shape being superimposed on the fundamental frequency produced by the vocal folds. The general theory of formants was stated by the great German scientist Hermann Helmholtz almost years ago. But the notion of a single format actually the second formant had been observed several centuries earlier. Spectrogram is used to analyze sounds and show their separate components.

The apparent point of origin of the formant for each place of articulation is called the locus of that place of articulation Evidence of voicing near the baseline during a consonant closure is called a voice bar.

Voiced Vertical striations corresponding to the vibrations of the vocal folds Bilabial Locus of both second and third formants comparatively low Alveolar Locus of second formant about Hz Velar Usually high locus of the second formant Common origin of second and third formant transitions Retroflex General lowering of the third and fourth formants Stop Gap in pattern, followed by burst of noise for voiceless stops or sharp beginning of format structure for voiced stops Fricative Random noise pattern, especially in higher frequency regions, but dependent on the place of articulation Nasal Formant structure similar to that of vowels but with nasal formants at about , , and Hz Lateral Formant structure similar to that of vowels but with formants in the neighborhood of , , and Hz Approximant Formant structure similar to that in vowels, usually changing Wide-band spectrogram has been used in this case.

When the vocal folds vibrate, they produce what are called harmonics of their fundamental frequency of vibration. Harmonics are vibrations at whole-number multiples if the fundamental frequency. Thus when the vocal folds are vibrating at Hz, they produce harmonics at , , Hz, and so on.

Narrow-band spectrums are useful for determining the intonation, or tone, of an utterance. To summarize Spectrograms: The most reliable measurements will be those of the length of the segments, for which purpose spectrograms are often even better than waveforms.

Differences among vowels, nasals, and laterals can be seen on spectrograms, whereas it may be impossible to see these differences in the wave-forms. Spectrograms are usually fairly reliable indicators of relative vowel quality. The frequency of the first formant certainly shows the relative vowel height quite accurately. The second formant reflects the degree of backness quite well, but there may be confusions due to variations in the degree of lip rounding. For example, one can usually see whether a stop has been weakened to a fricative, or even to an approximant.

Affrication of a stop can be seen on most occasions. Trills can be separated from flaps and voiced from voiceless sounds.

One can also observe the relative rates of movement of different articulations. Spectrograms cannot be used to measure degrees of nasalization, nor are they much help in differentiating between adjacent places of articulations. For studying these aspects of speech, other techniques are more useful.

However, this is not the case. Nobody knows how many individuals share similar characteristics. Individual variation is also important from a general phonetic point of view.

Spectrograms can show relative vowel quality. One can also use formant plots. But it is not easy to say if the vowel in a given word as pronounced by one speaker is higher or lower than that of another speaker. In general, when two different speakers pronounce sets of vowels with the same phonetic quality, the relative positions of these vowels on a formant chart will be similar, but the absolute values of the formant frequencies will differ from speaker to speaker.

Much of the work of the applied phonetician today is concerned with computer speech technology and directed toward improving speech synthesis systems. The greatest challenges in the field of speech synthesis are concerned with improvements in intonations and rhythm. Synthetic speech often sounds unnatural because the intonation is too stereotyped. Airstream Mechanisms and Phonation Types In order to describe the various languages of the world, we need to consider the total range of the phonetic capabilities of humans.

There are several ways in which the sets of terms that we have been using to describe English must now be enlarged. In the first place, all English sounds are initiated by the action of lung air going outward; other languages may use additional ways of producing an airstream.
