Speakers differ from each other in their precise pronunciation and the same speaker may vary the pronunciation of the same word in different contexts. Speakers are at liberty to modify their pronunciations in various ways. That is, the uncritical application of these guidelines will not always result in a perfect narrow transcription. You need to understand clearly that the guidelines to narrow transcription provided below are not really “rules” but more of predictions. phonetic, transcription must be enclosed in brackets. Today, we will discuss some of the main “rules” for converting a broad transcription to a narrow transcription. In certain contexts etc.) have resulted in a complex relation between orthography and pronunciation.The transcriptions we have considered so far were phonemic transcriptions, (also used synonymously with broad transcriptions) which contain the minimum amount of phonetic detail needed in order to be able to distinguish between words.Ī narrow transcription contains phonetic detail which can often be predicted by ‘rules’. And there are "difficult" languages like Danish where certain historical sound changes (weakening of plosives and lowering of vowels Languages like Turkish where the problem largely can be solved simply by substituting orthographic symbols with phonemic ones without considering Moreover, for languages withĪlphabetic orthographies the problem of mapping graphemic symbols to phonemic ones does not have equal complexity. This excludes languages like Chinese (with a syllable based orthography) and Hebrew (consonantal orthography). The data-driven, predictive model is suited only for languages with alphabetic orthografies (where one grapheme largely corresponds to one phoneme). Since version 1.2, the present system utilizes exception lists, small "lexica" with words (typically of foreign origin) that cannot be transcribed properly even if they are included in the training lexicon. Other systems may be mainly lexicon-based and only resort to machine-generated transcriptions when words are not found in the lexicon. For "normal" native words it mostly produces correct results, however for words of foreign origin, some proper names, abbreviations etc. The transcription tool is not error free. It has been generated by a program that based on an Expectation–Maximization algorithm aligns graphemes and phonemes of the training lexicon and subsequently based on the alignments builds the tree structure. #Phonetic transcriptions to english code#More specifically, the Decision Tree is some machine generated code that decides how a grapheme should be transcribed phonemically given its left and right context. It doesn't look up words in a lexicon, but transcribes in accordance with the general rules it "learned" from the training lexicon. The transcription tool is based on a Decision Tree derived from a training lexicon (a list of orthographic forms and their phonemic counterparts).
