Off-line classification of Polish vowel spectra using artificial neural networks
The mid-frequencies and bandwidths of formants 1–5 were measured at targets, at plus 0.01 s and at minus 0.01 s off the targets of vowels in a 100-word list read by five male and five female speakers, for a total of 3390 10-variable spectrum specifications. Each of the six Polish vowel phonemes was represented approximately the same number of times. The 3390* 10 original-data matrix was processed by probabilistic neural networks to produce a clas…
Polish
Polish is a West Slavonic language with about 41 million speakers in Poland and approximately 10 million in diasporas. It can be described as a 'consonantal' language, in two respects: (a) it has a rich system of consonant phonemes, as shown in the table, and (b) it allows heavy consonant clusters, especially word-initially
Reduction of speaker-related variability in Polish vowel spectra
Sources of variability in the speech signal and their statistical treatment are discussed. In the experiment, a total of 3390 vowel spectra obtained from a specially constructed 100-word list read by five male and five female speakers were measured, described in terms of five variables, F 1 F 2 , F 3 , F 4 , F 5 and subjected to statistical analysis. First, the 5D data are normalized, and then treated using a novel discriminant analysis based on …

More on German [ç] and [x]
The two notes in JIPA 20(2) by Kohler (1990) and Ladefoged (1990) concerning the phonemic status of present-day Standard German ç] and [x] are one of many pieces of evidence that distributional (‘taxonomic’) phonemics has happily survived the thirty-year war with Generative Phonology and its offspring. But it is common knowledge among linguists that even half a century after Bloch's (1948) classic paper there is still no fixed and exhaustive set …
IPA Phonemic Transcription Using an IBM PC and Compatibles
We have designed special IPA characters for IPA phonemic transcriptions of the following languages: E[nglish—RP and GA], F[rench], G[erman], I[talian], P[olish], R[ussian], Sp[anish] and Sw[edish], using two different programs which can be run under MS-DOS (BIOS) on an IBM PC or compatible. One, the ChiWriter—henceforth CH—is a complete word processor whilst the other, the LETTRIX—henceforth L—has to be combined with a word processor, such as Wor…

Neutralization of voicing in Polish obstruents
The Phonology of Modern English
Re-defining English accent and stress
In a well-known introductory text on linguistics, Langacker maintained (1968: 161), expressing a widely held view:Linguists do not fully understand just what constitutes stress. The best we can say is that stressed vowels are apparently different from unstressed ones in that they are of greater length, higher pitch and greater articulatory force
On the Distributional Analysis of Pitch Phenomena
Both the present analytical techniques and methods of structuring pitch data in language are not entirely satisfactory. Neither traditional procedures, essentially aimed at didactical applications nor the more theoretical work done on transformational-generative lines have reached sufficient depth of insight or fully accounted for available data. For general methodological reasons it is preferable to try to elaborate a distributional theory of li…
Speech Audiometry for Children and Subjective Probability of Polish Words
Word lists used for speech audiometry should fulfill a number of conditions in order that the results of hearing tests be unambiguous and directly interpretable not only in terms of possible hearing loss but also in terms of the neurolinguistic decoding process. In order to construct a proper word list, it was decided to attempt to estimate the subjective probability of word occurrence in schoolchildren. Nine different lists of over 300 words eac…
A Model of Standard German Intonation
Pitch and compass of the speaking voice
There are many unsolved problems concerning the linguistic interpretation of intonation curves obtained instrumentally. Among the major ones are (1) How accurate must the instrumental data be to make sure that no linguistically relevant information is missed? (2) Which of the details of the intonation curve are linguistically relevant? (3) How should the graph be scaled? (4) How should the curves be normalized so as to neutralize individual (spea…
Nasal vowels in contemporary Standard Polish: An acoustic-phonetic analysis

Acoustic Correlates of Stress
The use of the term ‘stress’ is reviewed, and inconsistencies are pointed out An experiment is described in which synthetic nonsense syllables of the forms /sisi/, /S⊃S⊃/ and /sasa/ were played to subjects who were asked to judge the position of the stress. The parameters of fundamental frequency, intensity and duration were varied systematically. The results revealed a high level of consistency between the (naive) subjects. Variations in fundame…
The Formants of Fricative Consonants
Spectral analysis of American English, Swedish and Polish fricatives shows that these sounds may be classified according to the relations between their formant frequencies and formant levels. Three binary distinctive features at the acoustic-phonetic (not necessarily phonemic) level are postulated: spread/compressed formants (F4–F2); higher/lower formants (F2+F3+F4); higher formant/lower formant emphasis (L4–L2 or L3–L2). A possibility of further…
