Minjaee is the general name of some dialects of Luri that are known as Khorramabadi, Balageriveie, Silakhori, Boroujerdi, Malayeri, and so on. This study presents the acoustic parameters such as the first formant frequency and second formant frequency of Minjaee Luri monophthongs. As well it aims at studying the effect of gender and syllable (open and close) on these parameters. Finally, it is possible to obtain the vowel space diagram of Khorramabadi and Balageriveie dialects. The acoustic parameters of Minjaee Luri vowels /i/, /ɪ/, /ʏ/, /e/, /ø/, /a/, /ə/, /u/, /o/, /ɑ/, have been studied according to totally 1217 phonetic samples, produced by 18 participants (12 males and 6 females). Phonetic samples were analyzed by using PRAAT and the results were analyzed by SPSS. The study results were reported in two parts of descriptive and analytical statistics. According to the first formant frequency, vowels /a/ and /i/ are the highest and lowest vowels, respectively. Vowel /i/ shows the highest second formant frequency and is the frontest vowel in this dialect. While vowel /a/ in males and vowel /o/ in females are the most back ones. The vowel roundedness was investigated; it reduces the second formant of vowels. Men’s first and second formant frequencies are lower than women’s.

In their article in Elm-e Zaban (Volume 7, Issue 11) titled “Acoustic Analysis of Glottal Stop Occurrence before Initial Vowels in Persian Words”, Navab Safavi et al report the findings of their research on the acoustic features of the glottal stop before the word-initial vowels in the Persian language and try to answer the question whether this sound is a phoneme or not. The research is based on the recorded pronunciation of some non-words with the CVCV syllable structure and also 30 Persian words with word-initial glottal stops (or “vowels” as the authors argue). The authors suggest that the criteria for the existence of the glottal stop consonant in the word group are not verified and conclude that a full glottal stop with the characteristics of a consonant does not exist before the word-initial vowels in the Persian language. It seems that this acoustic research suffers from weaknesses in terms of assumptions, critique of previous studies, methodology, conclusion, and references. The most serious weakness is the confusion between the realms of phonology and phonetics, and the lack of distinction between the status and characteristics of the two branches of linguistics. This reply takes up a number of phonological and methodological issues which challenge the main conclusions of the authors.

The present study, in the context of computational linguistics and acoustic phonetics, attempted to determine the acoustic features of glottal stop before the word initial vowels in the Persian language and to answer the question whether this sound is a consonant or is the characteristic of the initial vowel in the Persian. The research test groups consisted of three groups: (a) nonword group in which the vowel is located after a consonant except glottal stop, (b) nonword group in which the presence of glottal stop is clear before the vowel, and (c) the group containing 30 words of Farsi language which begin with vowels. The three groups were read and recorded by 16 sample members at the studio. Then, they were subjected to acoustic measures, duration, first formant, intensity and spectral tilt of vowels evaluation using The Praat software. The numerical values obtained were analyzed based on mean indices, variance and Scheffe test. It was found that the criteria for the existence of the glottal stop consonant in the word group were not verified; as a result, the complete stop that has the acoustic characteristics of a consonant does not exist before the word initial vowels in the Persian language. Therefore, the incomplete obstruction can be taken as the phonetic process that is added at the beginning of the initial vowel production, and it makes that vowel glottalized.

Two anterior aphasic patients (one man and one woman) were recorded for their productions of six Persian vowels and were compared to a group of four normal speakers (two men and two women). Praat was used to obtain the spectrograms of the sound files. Vowel duration values showed that normal women produced longer vowels compared to normal men. The male patient produced all vowels shorter, and the female patient produced all vowels longer than all four normal subjects. Although there were no significant differences in the formant frequency values of the four non-round vowels across groups, the two round vowels /o, u/ showed a pattern different from that of other vowels in aphasic speech
