“…There have been preliminary suggestions published for such ASCII codings (e.g. Lennig and Brassard, 1984;Wells, 1986), and we note that the International Phonetic Association is taking an active interest in the issue. For example, the issue is on the agenda of the Association's meeting to be held in Kiel in 1989 ( Ladefoged, 1987).…”

Acquiring the skill of phonetic transcription from orthographic text is a widespread technique included in all undergraduate curricula for phonetics, linguistics and speech science. It is an ability which is also frequently expected in students of modern languages and English. Any instructor who has been faced with a pile of thirty and more transcriptions to mark knows what a laborious task this is, requiring a lot of close examination of fine detail. To be able to lighten the load by computerizing some of the detail of error-correcting is therefore seen as desirable from several points of view.

“…The speech samples were recorded with a sampling frequency of 12000 Hz and 16-bit linear quantization. The speech signals of all the spoken sentences in the database were segmented into individual phonemes and were labeled utilizing the Machine Readable Phonetic Alphabet (MRPA) [14]. A total number of 31663 "phonemes" were labeled, but to maintain consistency with Nakajima et al's study (2017) [8], in which the phoneme labeling of this database had to be reexamined, 7523 were omitted, and the same 24140 English phonemes were taken up as analysis samples.…”

A newly developed factor analysis, origin-shifted factor analysis, was compared with a normal factor analysis to analyze the spectral changes of English speech. Our first aim was to investigate whether these analyses would cause differences in the factor loadings and the extracted spectral-factor scores. The methods mainly differed in whether to use cepstral liftering and an origin shift. The results showed that three spectral factors were obtained in four main frequency bands, but neither the cepstral liftering nor the origin shift distorted the essential characteristics of the factors. This confirms that the origin-shifted factor analysis is more recommendable for future speech analyses, since it would reduce the generation of noise in resynthesized speech. Our second aim was to further identify acoustic correlates of English phonemes. Our data show for the first time that the distribution of obstruents in English speech constitutes an L-shape related to two spectral factors on the three-dimensional configuration. One factor had center loadings around 4100 Hz, while the other was bimodal with peaks around 300 Hz and 2300 Hz. This new finding validates the use of multivariate analyses to connect English phonology and speech acoustics.

“…For the author, a specific alert was sounded for the urgency of attention to the chart when some particular recent phonetic research appeared. In the last two years, several proposals have been circulating for the conventionalized representation of IPA symbols (both vowels and consonants) in ASCII machine code, so that phonetic symbols may be standardized internationally on computers (see for example Lennig and Brassard (1984); Wells (1986)), as is especially useful for publishing purposes. Such systematization is, of course, admirable and long-overdue.…”

The IPA consonant chart: Mugwumps, holes and therapeutic suggestions

For some time now it has been clear that the International Phonetic Alphabet consonant chart needs to be carefully re-examined, with a view to its intended provision and possible revision. This article appears as part of the current drive (see also Ladefoged (1987a)) to solicit suggestions for the improvement or revision of the chart, from all the manifold users of the IPA alphabet. The focus here is on the consonant chart, for while the representation of vowels has always been more problematic, the theoretical issues are of a different order and should be discussed separately.
