The example focuses on extracting and plotting vowel formants in an easy but also very uncontrolled way. However, before continuing a word of warning is in order.
The subsequent sections elaborate the above steps. Measure and extract the first and second formant of each vowel Record words in which all monophthongal vowel sounds of a given variety occur To produce a personalized vowel chart, the following steps are necessary: Such vowel charts can then be used in language learning as corrective feedback (see Paganus et al. This means that we do not necessarily have to plot the position of the tongue of a speaker when he or she produces vowels to create a vowel chart but that analyses of audio recordings of words in which vowels occur, can be utilized to plot a personalized vowel chart of a speaker. During acoustic analysis, the complex wave is deconstructed into its component parts, i.e. the simple periodic waves that make up that sound. In other words, vowels are periodic, i.e. rhythmic, compressions and decompressions of air and to create a vowel sound, i.e. a complex periodic wave, one needs to produce several simple periodic waves simultaneously. Formants are frequencies of air waves that, if collapsed, form a complex vowel sound (Johnson 2003 Ladefoged 1996). Interestingly, a very similar figure can be created by plotting the Hertz frequency of the first formant of monophthongal vowel sound against the Hertz frequency of second formant minus the Hertz frequency of the first formant of a monophthongal vowel sound. A vowel chart for the monophthongal vowel phones in Received Pronunciation (RP) is shown below.įigure 1: Vowel Chart of monophthongal vowel sounds in Received Pronunciation (RP) (left) Tongue positions for the vowels /i, e, E, a/ (right) The latter two features are used in the production of vowel charts which show where in the mouth the tongue is located during the production of monophthongal vowel phones. The number of tongue positions during vowel production (to differentiate between mono-, diph-, and triphthongs), The criteria for differentiating between different vowel sounds are As vowels are produced without obstruction of the air stream, other criteria for differentiating between vowel sounds are needed. In fact, consonants are classified according to the manner and place of the obstruction of the air stream. Consonants differ from vowels in that they are formed with an obstruction of the air stream coming from the lungs and they cannot form the nucleus of a syllable (Zsiga 2012). When learning or studying a language - the case in point here being English - it is likely that you are confronted with different classes of sounds, e.g. consonants and vowels (Rogers 2014).
